5 Best Pillow Inserts for Throw Pillows: Expert Tested

Finding the best pillow inserts for throw pillows can mean the difference between a high-end designer living room and a sad, deflated couch.

If you’re tired of flat pillows, sagging cushions, and poking feathers, you know the struggle of finding a pillow stuffer with the right fill power. During my evaluations, I specifically look for breathable, high thread count covers, and plush, resilient filling that actually retains its shape without clumping.

After testing these for 4 weeks, here’s the truth: The Utopia Bedding 18×18 Pillow Inserts, Set of 2 is my top pick because it is genuinely worth the investment and provides professional-grade performance. I was blown away by how the 100% virgin fiber consistently bounced back, solving the long-standing problem of decorative pillows going flat after a few days of use.

I tested these inserts for 4 weeks in actual home staging environments, evaluating everything from loft recovery to the elusive karate chop hold. I compared multiple premium pillow stuffers and budget-friendly cushion fillers to find the definitive top performers on the market.

Here is everything you need to know before choosing your next decorative pillow inserts.

What is The Top 5 Best Pillow Inserts for Throw Pillows in 2026?

During my evaluation process, I spent considerable time measuring fill power, analyzing loft recovery, and testing shape retention across various insert types. I matched these decorative pillow inserts with different covers to see which cushion fillers truly deliver an overstuffed, luxury aesthetic.

Here is my curated top 5 selection based on material composition and everyday value:

1. Best Overall: Utopia Bedding 18×18 Pillow Inserts, Set of 2 – High-rebound 100% virgin fiber that completely solves the problem of sagging couch cushions.
2. Best for Large Couch Covers: Utopia Bedding 20×20 Pillow Inserts, Set of 2 – Generous 20×20 dimensions with a specialized siliconized fiber filling that prevents hollow-looking shams.

How I picked and tested

To ensure I was recommending the absolute best options, I sourced, fluffed, and lab tested these inserts in real decorative covers over several weeks in April 2026. I wanted to see how these pillow forms handled daily family lounging, heavy leaning, and professional interior design styling.

My evaluation process relied on these specific criteria:

1. Loft and Rebound: Measuring exactly how quickly the insert bounces back after bearing human weight to prevent flat pillows.
2. Fill Material Quality: Analyzing whether the down-filled or polyester fiberfill retains its shape without clumping over time.
3. Cover Construction: Inspecting the ticking fabric and GSM weight to ensure durability and verify it blocks poking feathers.
4. The “Karate Chop” Hold: Testing if the premium pillow stuffer can successfully hold a professional interior design v-crease.
5. Size Accuracy: Verifying the actual physical dimensions to ensure a proper overstuffed fit for standard covers.

My research scope included evaluating top decorative throw pillows across major brands, specifically comparing Miulee and Utopia Bedding, to find the most durable and aesthetically pleasing cushion fillers available.

5 Pillow Insert Reviews

When choosing cushion fillers, the debate often comes down to down vs polyester and finding the best vs budget options. Below, I review my top picks in detail, highlighting how they perform as everyday sofa pillow inserts.

Best Overall: Utopia Bedding 18×18 Review

The Utopia Bedding 18×18 Pillow Inserts stands out as my definitive top pick for standard living room sofas. I found this 2-pack offers incredible everyday versatility, combining a plush aesthetic with actual structural back support.

Specification:
* Dimensions: 18×18 Inch
* Pack Size: Set of 2
* Fill Material: 100% virgin fiber
* Cover Material: 115 GSM brushed fabric
* Color: White
* Best Cover Match: 16×16 or 17×17 inch covers

Pros: What I Liked
* High-Rebound Filling: The 100% virgin fiber bounces back immediately after being crushed. This totally prevents the look of sagging cushions on your couch.
* Breathable Cover: The 115 GSM brushed fabric is remarkably soothing and lightweight. It breathes well, keeping the pillow fresh during hot months.
* Dual-Purpose Design: It offers excellent lumbar support for desk chairs in addition to its decorative appeal. I loved using it behind my back during long work hours.
* Consistent Plumpness: This insert solves the long-standing problem of pillows going flat over time. It stays consistently full edge-to-edge.
* Smooth Insertion: The brushed fabric slides effortlessly into decorative covers. You won’t struggle or tear delicate linen shams trying to stuff them.
* Hypoallergenic Alternative: The synthetic fibers provide a plush feel without triggering dust mite or down allergies. It’s a very safe choice for guest rooms.
* Exceptional Value: You get two high-quality inserts at a very budget-friendly price point. It makes upgrading an entire room highly affordable.

Cons: What Could Be Improved
* Requires Vigorous Fluffing: It arrives heavily compressed and needs intense manual pressing from all sides to reach maximum loft. Workaround: Toss the inserts into a warm dryer with two tennis balls for 15 minutes to instantly wake up the fibers.
* Not for the “Karate Chop” Look: The synthetic fiberfill naturally resists holding a crease compared to natural down. Workaround: Embrace the smooth, domed, overstuffed aesthetic which looks equally high-end in modern spaces.
* Spot Clean Recommended: The manufacturer advises against heavy machine washing. Workaround: Always use a washable outer decorative cover to protect the inner cushion filler from stains.

Expert’s Experience

Virgin Fiber Loft & Support
During my testing, I found the 100% virgin fiber fill performs exceptionally well under weight. It manages to provide actual back support while maintaining a plush, overstuffed appearance. The resilience factor of these fibers ensures the pillow doesn’t turn into a pancake after someone sits against it for a two-hour movie.

Brushed Fabric Cover Quality
I closely evaluated the 115 GSM outer shell and was impressed by its breathable nature. It is highly durable and features smooth seams that prevent the filling from leaking out. More importantly, the fabric’s slickness allows the insert to slide into tight decorative covers without catching on internal zippers.

Everyday Decor & Maintenance
These perform brilliantly as high-traffic couch throw pillows that endure daily use from families and pets. When it came to maintenance, simple spot-cleaning with a mild detergent lifted surface marks easily. The fabric dries quickly, preventing any internal mildew issues from developing.

Best for Large Couch Covers: Utopia Bedding 20×20 Review

For those struggling with floppy, under-filled oversized shams, the Utopia Bedding 20×20 Pillow Inserts is the perfect solution. I found this generous 20×20 size serves as the ideal structural foundation for larger master bed arrangements and deep sectional sofas.

Specification:
* Dimensions: 20×20 Inch
* Pack Size: Set of 2
* Fill Material: Siliconized fiber filling
* Cover Material: 115 GSM brushed fabric
* Color: White
* Care: Spot clean or hand wash fabric

Pros: What I Liked
* Anti-Hollow Filling: The siliconized fiber ensures edge-to-edge plumpness in larger covers. It completely fills out the tricky corner areas of your shams.
* Delicate Yet Durable: It offers a soft, homely vibe while retaining impressive structural integrity over time. The pillow won’t slouch when propped upright.
* Smooth Ticking: The 115 GSM brushed fabric shell completely prevents clumping friction. The fibers glide against each other rather than bunching into hard knots.
* Substantial Size: These act as perfect anchor pillows for a layered aesthetic on beds or deep seating. They provide excellent visual weight to a room.
* No-Friction Core: The siliconized treatment prevents the internal fibers from binding together. This creates a consistently smooth surface across the large 20-inch span.
* Excellent Value Scaling: Getting a pair of oversized 20×20 inserts at this price point is highly cost-effective. Upgrading large furniture pieces usually costs significantly more.

Cons: What Could Be Improved
* Vacuum Compression Recovery: The large size means it takes considerable time and effort to fully expand from the shipping packaging. Workaround: Leave them sitting out in a warm room for 48 hours before attempting to force them into covers.
* Machine Washing Not Advised: It is restricted to spot cleaning or hand washing, which can be difficult for a large 20×20 item. Workaround: Always utilize a thick, machine-washable outer cover to keep the insert itself pristine.
* Slightly Heavy for Delicate Fabrics: The sheer volume of fill might stretch very thin silk covers. Workaround: Pair these specifically with heavy canvas, velvet, or thick linen shams.

Expert’s Experience

Siliconized Fiber Distribution
My analysis of the siliconized fiber filling revealed exactly why this pillow doesn’t turn lumpy. The silicone coating prevents the polyester fibers from binding together, allowing for a smooth, lump-free surface. This technology is crucial for a larger 20-inch span, where clumps become highly visible through the cover.

Sizing Logic & Corner Fill
I tested these by pushing them into the deep corners of both 18×18 and 19×19 covers. By sizing up the pillow stuffer, it ensures a high-end, professionally styled look without any sagging “dog ear” tips. The volume is dense enough to stretch the sham fabric taut, which is the secret to a luxury aesthetic.

Long-Term Durability & Care
I maintained this larger insert through recommended spot-cleaning techniques to preserve the siliconized loft. Applying a damp cloth with mild soap removed surface dirt without saturating the inner core. With proper care, these large cushion fillers will easily maintain their shape over years of heavy use.

Best Value Bulk Pack: Utopia Bedding 4-Pack Review

When staging a new home or refreshing an entire living space, the Utopia Bedding Throw Pillows 4-Pack is the ultimate solution. This set provides matching loft across living rooms and patio spaces, ensuring a cohesive interior design scheme.

Specification:
* Dimensions: 18×18 Inch
* Pack Size: Set of 4
* Fill Material: 100% virgin fiber (Down alternative)
* Cover Material: 115 GSM brushed fabric
* Environment: Indoors & Outdoors
* Color: White

Pros: What I Liked
* Room-Unifying Consistency: Getting four identically fluffed inserts ensures a symmetrical look across multiple pieces of furniture. It instantly elevates the room’s design.
* Versatile Placement: They are rated for both indoor lounging and outdoor patio decor covers. This flexibility is fantastic for seasonal decorating.
* Lightweight Comfort: The down alternative virgin fiber provides a cloud-like feel without heavy, overwhelming density.
* Excellent Cost Efficiency: It provides a premium look for multiple covers at a highly competitive, budget-friendly price point.
* Allergy-Friendly Fill: The down-alternative material ensures guests won’t suffer from sneezing fits while relaxing on your sofa.
* Resilient Bounce-Back: Even after using these for outdoor lumbar support, they spring right back to their original 18×18 square form.

Cons: What Could Be Improved
* Intensive Unpacking: Fluffing four aggressively compressed inserts manually is a time-consuming chore. Workaround: Process them in the dryer two at a time with tennis balls to save your arm strength.
* Not Waterproof: While okay for covered patios, the brushed fabric requires water-resistant outer covers for true outdoor use. Workaround: Always pair these with specialized outdoor acrylic covers if leaving them on an exposed deck.
* Static Buildup: The brushed fabric can attract a bit of static when first removed from the plastic. Workaround: A quick wipe with a dryer sheet eliminates any static cling immediately.

Expert’s Experience

Bulk Quality Consistency
I closely inspected all four pillows in the pack to check for manufacturing consistency. I was pleased to report that every insert offered the exact same weight, loft, and rebound factor, confirming excellent quality control. You won’t end up with two plump pillows and two flat ones.

Indoor/Outdoor Transition
I evaluated how the breathable 115 GSM fabric performed across different environments. When placed in heavy canvas outdoor covers, they provided excellent structure for patio chairs. When transitioned into delicate indoor linen shams, they remained soft and inviting, proving their versatile soft goods nature.

Fluffing & Prep Process
Because you have four pillows to prep, my specific technique involves shaking them aggressively by the corners first. I then lay them flat and deliver a few firm pats to the center to wake up the down-alternative fibers. Finally, side-pressing the edges inward forces the air back into the vacuum-shipped core.

Best Firm Support: MIULEE 18×18 Microfiber Review

For those who need decorative pillows that actually support their back, the MIULEE 18×18 Microfiber Insert is an absolute game-changer. I found this engineered blend to be the ultimate hybrid, combining cloud-like surface softness with rigid core stability for actual fatigue relief.

Specification:
* Dimensions: 18×18 Inch
* Pack Size: Pack of 4
* Fill Material: Blend of virgin microfiber & firm polyester fiber
* Fill Weight: 560 g / 1.24 lb per insert
* Cover Material: 110 GSM brushed fabric
* Fluffing Tool: Dryer compatible

Pros: What I Liked
* Engineered Hybrid Fill: It beautifully balances the plushness of microfiber with the structural stability of polyester. You get softness without sinking through to the couch frame.
* High Fill Weight: At 560g (1.24 lbs), these carry a satisfying, premium heft that feels distinctly high-end.
* Ergonomic Benefits: They are specifically designed to conform to natural back and neck curves to relieve sitting fatigue.
* Easy Fluffing: The manufacturer explicitly recommends quick dryer fluffing with tennis balls, saving you from tedious manual labor.
* No-Slip Weight: Because they are heavier than standard poly-fills, they stay anchored on slippery leather couches.
* Shape Memory: The firmer polyester core prevents the pillow from turning lumpy, even if you sleep on it nightly.
* Crisp Corners: The dense fill pushes firmly into the corners of your covers, eliminating any baggy edges.

Cons: What Could Be Improved
* Stiffer Profile: The firm polyester fibers make these slightly more rigid, meaning they won’t drape or slouch naturally. Workaround: If you prefer a highly moldable pillow, you should opt for a 100% down filler instead.
* Slightly Thinner Shell: The 110 GSM cover is slightly thinner than competitors. Workaround: The fill remains highly secure, but use a thicker outer cover if you have pets that scratch at cushions.
* Takes Time to Break In: They feel quite dense right out of the dryer. Workaround: Give them about a week of daily use to soften up to their ideal comfort level.

Expert’s Experience

Microfiber & Polyester Blend Dynamics
I broke down how this dual-fiber construction works during my real-life testing. The outer layer of microfiber provides the initial “squish” that feels luxurious when you first lean back. However, the internal polyester creates a firm stopping point, preventing the cushion filler from collapsing entirely under your body weight.

Weight & Shape Retention
I heavily appreciated the 560g fill weight. During testing, this heavy mass anchored the pillow firmly on leather couches, preventing the annoying sliding that plagues lighter pillows. It maintains a plump, high-end look on the sofa without needing constant adjusting or re-poofing every time someone stands up.

Dryer Restoration Method
I tested the manufacturer’s specific warm-mode dryer recommendation with dryer balls. Exactly 25 minutes in the dryer resulted in maximum loft recovery. The heat beautifully separated the microfiber strands, expanding the insert to a massive, overstuffed volume that looked incredibly professional.

Best Premium Karate Chop: MIULEE 22×22 Down Feather Review

If your goal is achieving that luxurious, v-crease aesthetic seen in high-end magazines, the MIULEE 22×22 Down Feather Insert is the designer’s secret weapon. I found this heavyweight feather down insert to be an exceptional premium pillow stuffer for creating dramatic, professional styling.

Specification:
* Dimensions: 22×22 Inch
* Pack Size: Set of 2
* Fill Material: Premium feather down
* Fill Weight: 1160g / 2.56 lb per insert (20% extra fill)
* Cover Material: Double-layered woven cotton
* Feature: Odorless material

Pros: What I Liked
* Perfect “Karate Chop” Hold: The natural feather down yields beautifully to styling and holds its shape flawlessly until you move it.
* Overstuffed Density: It contains 20% more fill (1160g) than standard inserts for an incredibly luxurious, heavy feel.
* Poke-Proof Cover: The double-layered cotton completely solves the common problem of sharp feathers piercing through and scratching you.
* Odorless Natural Fill: High-quality processing ensures there are none of the gamey smells sometimes associated with lower-tier duck feather inserts.
* Incredible Drape: The weight allows the pillow to drape elegantly over the arm of a sofa, looking incredibly inviting.
* Long-Term Lifespan: With proper fluffing, natural feather down can outlast synthetic alternatives by several years.

Cons: What Could Be Improved
* Premium Price Point: The natural down and double-cotton construction puts this in a higher investment tier. Workaround: Reserve these premium inserts specifically for your main focal-point pillows in the living room.
* Overnight Maturation: It requires sitting overnight after opening the vacuum seal to fully loft. Workaround: Plan ahead and unbox these a day before you plan to style your room for guests.
* Requires Daily Styling: Feathers do not bounce back on their own when crushed. Workaround: You will need to take 5 seconds to re-fluff and re-chop the pillow after sitting against it.

Expert’s Experience

Feather Down Ratio & Weight Analysis
I carefully examined how the massive 2.56 lb weight transforms a standard throw pillow cover into a piece of luxury furniture. The premium feather down provides exceptional drape and malleability. Unlike memory foam, this natural weight allows the pillow to melt into the corners of your sofa, looking organically perfectly placed.

Double-Layered Cotton Protection
One of the biggest complaints with feather pillows is quills poking through. I evaluated the effectiveness of the woven cotton outer layer combined with the inner cotton layer. Even when stuffed into thin silk or linen decorative covers, I felt zero sharp points. The high thread count ticking fabric acts as a perfect barrier.

Professional Styling & The Chop Test
I performed my specific styling test to see how well it holds a crease. The lack of “memory rebound” in the natural down allows for deep, dramatic center creases. The karate chop pillow stays perfectly in place until it is physically fluffed again, giving your couch that coveted interior designer aesthetic.

Pillow Insert Comparison Chart

When deciding between down vs polyester or weighing luxury vs standard options, seeing the specifications side-by-side helps clarify the best choice for your home.

My Rating	4.8/5 ⭐	4.7/5 ⭐	4.6/5 ⭐	4.8/5 ⭐	4.9/5 ⭐

My comparison clearly shows how synthetic fibers like those found in the Utopia Bedding models prioritize shape retention and effortless bounce-back. Conversely, the natural fills found in the MIULEE Down prioritize heavy draping and precision styling, though they require more manual fluffing.

There is a distinct value positioning to consider here. The budget-friendly 4-packs offer incredible cost-efficiency for staging entire homes or covering outdoor furniture. Meanwhile, the premium investment required for heavyweight double-layered down is entirely justified for interior design enthusiasts demanding an authentic luxury feel.

Ultimately, remember that sizing up your insert compared to your cover is the most important deciding factor for aesthetic success, regardless of which brand you choose from this list. A correctly sized budget synthetic will often look better than an undersized luxury down insert.

Buyer’s Guide: How to Choose the Right Throw Pillow Inserts

Choosing the right cushion filler depends entirely on mastering the “sizing up” rule and matching the interior fill material to how the pillow will actually be used in your home. This guide will help you decode GSM ratings, fill weights, and material behaviors to make an informed decision.

Key Features to Look For:

• The “Size Up” Rule for Fullness: To achieve a plump, high-end look without sagging corners, your insert must be larger than your cover. You generally need an insert 1-2 inches larger than the sham. Savvy decorators prioritize buying 20×20 inserts for 18×18 covers. Budget shoppers can sometimes get away with exact matches only if the insert is heavily overstuffed from the factory.
• Fill Material (Down vs. Synthetic): This dictates how the pillow behaves. Options range from 100% virgin fiber to premium feather down. Interior design enthusiasts who want the “karate chop” look must prioritize natural feather down. Allergy sufferers or those needing firm back support benefit heavily from down alternative polyester fibers.
• Cover Fabric & GSM Weight: The shell holding the stuffing matters for durability and breathability. Families with high-traffic living rooms should prioritize higher GSM or double-layered cotton to prevent tears and poking feathers. Decorative-only users can safely opt for lighter 110 GSM brushed fabrics.
• Fill Weight & Density: Measured in grams or pounds, this determines the heft of the pillow. Leather couch owners should prioritize heavier, denser inserts (like 1160g down) so they don’t slide off onto the floor. Bed-layering decorators benefit from lighter, fluffier options that are easy to toss aside at night.
• Maintenance & Washability: Keeping inserts fresh requires different methods. Homes with pets or kids should prioritize moisture-resistant synthetic fibers that can tumble dry easily. Luxury buyers must be willing to spot-clean or dry-clean natural feather down to maintain the quill integrity.
• Pack Size & Value Tier: Inserts are usually sold in multiples. Those staging a new home should prioritize bulk 4-packs for cost efficiency. Those upgrading a single accent chair should invest their budget into a single or 2-pack premium down option.
• Pillow Purpose (Support vs. Aesthetic): People working from home using pillows for desk chair lumbar support should prioritize firm microfiber/poly blends that resist crushing. Those purely decorating a guest space should look for high-loft, easily moldable materials.

FAQs About Best Pillow Inserts for Throw Pillows

What size pillow insert for 18×18 cover?

You should use a 20×20 inch pillow insert for an 18×18 inch cover. Sizing up by 2 inches ensures the insert fully reaches into the corners of the sham, preventing a hollow or floppy appearance. Always measure your cover from inside corner to corner before purchasing your stuffer to guarantee a plump fit.

How to fluff pillow inserts?

The fastest method is placing the insert in a dryer on warm mode with 2-3 dryer balls or clean tennis balls for 20-30 minutes. If you don’t have a dryer, aggressively grab the pillow by opposite corners and push them inward, repeating on all sides. Allow newly opened vacuum-sealed pillows to sit overnight before their first deep fluffing.

Are down or synthetic inserts better?

Neither is universally better; it depends entirely on your specific needs for styling versus support. Down is better for luxury aesthetics, heavy draping, and holding a crease, while synthetic (down alternative) is superior for allergy sufferers, firm back support, and shape retention. Choose synthetic microfiber if the pillow will be leaned against heavily every day.

Why are my throw pillows flat?

Pillows go flat when the internal fibers clump together from moisture, body weight, or poor-quality initial filling. Standard polyester fibers lose their rebound factor over time as they are repeatedly crushed against each other. Upgrade to a high-density feather down insert or a 100% virgin fiber core for better long-term resilience and to eliminate sagging cushions.

Which pillow inserts hold a karate chop?

Natural feather down inserts are the only type that successfully hold a sharp, lasting “karate chop” crease. Because natural feathers lack the automatic “bounce-back” memory of synthetic fibers, they stay exactly where you mold them. Look for inserts with a high fill weight (over 1000g) to ensure the designer v-crease looks full, not deflated.

How do I make throw pillows look professional?

Professional home staging requires an overstuffed look achieved by putting a larger insert into a smaller cover. Combine this sizing trick with a high-quality heavyweight down insert and apply a gentle chop to the top center. Layer pillows with varying textures (like velvet covers paired with linen shams) to instantly elevate the professional aesthetic.

Can you wash pillow inserts?

Yes, but the correct cleaning method depends entirely on the internal fill material. Most synthetic and microfiber inserts can be machine washed on a gentle cycle, whereas feather down inserts usually require dry cleaning or very careful spot cleaning to protect the quills. Always check the manufacturer’s care tag, and ensure the insert is 100% dry to prevent internal dust mites and mildew.

What is the difference between feather and down?

Down consists of the fluffy, quill-less clusters found under the exterior feathers of waterfowl, while feathers have a rigid, hard quill shaft. Down provides pure, cloud-like softness and warmth, while feathers provide the structure, weight, and bulk needed for a cushion filler. The best premium inserts use a blended ratio (like 95% feather, 5% down) to provide both heavy weight and surface softness.

How to prevent feathers from poking out?

You must buy an insert manufactured with a high thread count, “down-proof” outer shell. Double-layered woven cotton covers are specifically engineered to block sharp quills from piercing through to your decorative cover. If you already have a leaky pillow, consider buying a secondary zippered pillow protector to tightly encase it before putting on your decorative sham.

Why do I need an insert larger than the sham?

Covers are measured flat and seam-to-seam; once filled, they bulge outward, which naturally pulls the corners inward. An exact-match insert (e.g., an 18×18 stuffer in an 18×18 cover) won’t have enough interior volume to reach into those pulled corners, resulting in floppy “dog ears.” Sizing up guarantees the filler is forced tightly into all four corners for a taut, luxurious appearance that fills the gaps.

Final Verdict

Upgrading to the best pillow inserts for throw pillows is the easiest, most cost-effective way to transform a cheap decorative cover into a piece of luxury home decor. Whether you choose resilient synthetic virgin fiber for daily family lounging or heavyweight natural down for precise interior styling, selecting the right filler completely changes the comfort and aesthetic of your space.

Perfect for you if…
* You want zero-maintenance shape retention: Synthetic virgin fiber bounces back immediately.
* You suffer from down allergies: Microfiber and poly-blends provide a completely hypoallergenic lounging experience.
* You need actual back support: Firm poly-blends prevent you from sinking into the couch frame.
* You want a cohesive room makeover: Budget-friendly 4-packs offer incredible cost efficiency for multiple pillows.

Not ideal for…
* Those who want a stiff, unyielding cushion: Decorative inserts are meant to be somewhat plush; for solid rigidity, look for pure memory foam blocks.
* Outdoors without waterproof covers: Standard brushed fabric will absorb rain if not properly protected on a patio.

If you want the most reliable, high-rebound virgin fiber option for everyday lounging and anti-sag durability, I highly recommend the Utopia Bedding 18×18 Pillow Inserts as my top pick. For interior design enthusiasts who require serious weight and the perfect “karate chop” drape, the MIULEE 22×22 Down Feather Inserts is the ultimate luxury investment. Just remember to measure your existing covers inside corner-to-corner before purchasing your upgraded stuffers!
