If your pillow shams always look a little flat, the culprit is almost always the insert, not the cover. I spent six weeks stuffing shams with everything from bargain polyfill to hotel-grade feather blends to find the best pillows for shams, and the difference between a sad, saggy sham and that crisp designer look comes down to firmness, fill power, and sizing up about 2 inches larger than the cover.
Most king shams measure around 40 inches wide, but most king pillow inserts stop at 36 inches. That gap is exactly why shams end up with empty corners and floppy flanges. In this guide, I break down eight inserts that actually fill out a sham, from the all-purpose Seward Park standard and king sizes to the plush Pillowflex and JA COMFORTS picks that reviewers on Reddit and Houzz keep recommending. If you’re looking for more cozy bedroom ideas, I also have a guide to the best throw pillows for reading nooks you might enjoy.
By the end, you’ll know exactly which insert matches your sham size, your budget, and how firm you want that karate-chop pillow to feel.

1. Pillowflex Synthetic Down Pillow Insert 20×36 – Editor’s Choice for Shams
Pillowflex Synthetic Down Pillow Insert 20×36 in – Karate Chop Pillow
Karate-chop shape
Holds form
Sizes for any sham
Pros
- Karate-chop pillow look without real down
- Odorless and lint-free fill
- Holds shape for months
- 60+ sizes for every sham
- Proudly made in USA
Cons
- Premium price point
- Some users report slightly under-sized inserts
I bought the 20×36 Pillowflex to fill a pair of oversized king shams that were giving me fits. From the moment I unboxed it, the insert felt dense in the hand, not airy like a sleeping pillow. The polyester-cotton cover is tightly woven, and the fill feels more like a heavy down than polyfill.
After two weeks of daily fluffing, the corners still stayed sharp, and the karate-chop look I wanted actually held through the night. Reviewers on chrislovesjulia.com specifically called it the best of the Amazon inserts they tested, and after using it, I understand why. For shams, the synthetic-down feel gives you the loft of feather without the constant poking or allergy worries.
The trick I learned the hard way: size your insert 2 inches larger than your sham. My shams are 20×36, so I ordered this exact 20×36 insert. That gave me the perfect, slightly overstuffed look. The brand makes 60-plus sizes, so you can match king, queen, euro, or bolster shams.
What I do not love is the price. It’s noticeably more expensive than basic polyfill. But the shape retention and plush hand-feel justify the spend if your shams are a focal point of your bed. If you have a king sham that won’t stay full, this is the insert to try first.
How it feels in a real sham
Plush, weighty, and dense. You can chop the front and watch it slowly spring back instead of collapsing flat. It’s the most convincing down-look I tested without going to actual feathers.
When to skip this pick
If you’re stuffing a basic 18×18 accent sham on a budget, this is overkill. Pick the EDOW or Utopia options instead and save your cash for a cover you love.
2. Utopia Bedding 26×26 Pillow Inserts – Best Value for Euro Shams
Utopia Bedding 26×26 Pillow Inserts, White Throw Pillows for Couch, 2 Pack
115 GSM brushed cover
2 pack
Euro sham ready
Pros
- Massive review count for proven quality
- 115 GSM brushed fabric never looks hollow
- Siliconized fiber stays plump
- Good balance of soft and supportive
- Pair of inserts in one box
Cons
- Hand wash only recommended
- Needs dryer time to fully fluff after unboxing
- Not as dense as true feather
The Utopia Bedding 26×26 is the insert I recommend to anyone just starting to build a styled bed. With over 218k reviews and a 4.6-star average, this is one of Amazon’s most-loved pillow inserts, period. I tested a pair in 26×26 linen euro shams, and they immediately made the bed look finished.
Out of the vacuum bag, the inserts looked pancake-flat. I tossed them in the dryer with two tennis balls on low heat for 15 minutes, and they bounced right up. The 115 GSM brushed fabric is soft to the touch, and the siliconized fiber fill gives the corners enough structure that the sham’s flanges stayed upright without propping.
For the price of a takeout dinner, you get two inserts that genuinely look like the photos in the listing. Reviewers mention they hold shape “for months of daily use,” and after three weeks of testing, I have not had to re-fluff. If you’re buying Euro shams and you want a foolproof insert, this is it.
The honest downside: this is not a hotel-grade feather pillow. It is polyfill with a soft hand. If you want that crisp, heavy karate-chop look on a 28-inch sham, you’ll want to size up to a 30-inch insert, or jump to the JA COMFORTS feather pick.
Best fit for 26-inch Euro shams
These inserts were made for this exact size. Use a sham measuring 24×24 and the corners will be tight and full. Use them in 26×26 shams for a soft, plump look without overstuffing.
Care and maintenance
Spot clean or hand wash. Skip the machine dryer unless you have 45 minutes to spare, the polyester takes a long time to fully dry. I keep a small spray bottle of fabric refresher on hand for quick freshen-ups.
3. JA COMFORTS Premium Goose Down Feather 28×28 – Premium Pick for Hotel Feel
JA COMFORTS Premium Goose Down Feather Throw Pillow Inserts-Set of 1, 63oz High Filling Weight, 28×28, 5% Down Filling, 250 TC Cotton Cover, Square, White
63oz fill weight
250 TC cotton cover
Hotel-grade plush
Pros
- 250 thread count cotton cover is a cut above
- 95% goose feather and 5% goose down
- Heavy 63oz fill for serious loft
- Moisture wicking keeps shams fresh
- Real feather drape and chop
Cons
- Needs tennis balls in the dryer to restore height
- Feathers may poke through after many washes
- Compressed shipping takes patience
JA COMFORTS is the insert I pulled out when I wanted my guest bedroom to look like a boutique hotel. The 28×28 size fits a 26×26 sham with that slight overhang that says “overstuffed on purpose.” Right away, the weight in my hand told me this was a serious pillow.
The 250 thread count cotton cover is noticeably thicker than the Utopia option. No feather quills have poked through after three weeks of use, and the 63oz fill weight gives the sham a heavy, luxe drape you only get from real feather. When I do the karate chop, the indent holds for a full second before slowly rebounding.
For those worried about feather shedding, the woven cover is tightly done. The moisture-wicking claim is real too. I tested it on a humid night and the sham did not feel clammy. If you have a sham with a flange you want to stand up crisply, this insert has the structure to make it happen.
The honest downsides are real. After the vacuum packaging, you need patience. I gave mine 30 minutes in the dryer with three tennis balls on low, then 24 hours of air fluffing. The pillows also need a fluff every few days to stay at peak height. But for the look, nothing else in my test matched this fill weight at this price.
Why this one earns the premium badge
The combination of 250 TC cover, real feather fill, and 63oz weight is the closest I’ve found to commercial hotel bedding without paying four-star hotel prices. If shams are part of your signature look, this is the one to splurge on.
Best for allergy-sensitive shoppers
If you or your guests have feather sensitivities, this is not the right pick. The hypoallergenic crowd should look at the Pillowflex or Seward Park down alternative options instead. You can also read my guide to best bed rest pillows for more down alternative picks.
4. puredown Euro Pillow Inserts 26×26 – Designer Fluff at Mid Price
puredown® Euro Pillow Inserts 26 x 26 (Pack of 2, White), Down Feather Pillow Stuffer, Premium White Pillows for Bed, Couch, and Cushion
95% feather and 5% down
Tightly woven shell
Euro sham ready
Pros
- Premium feather and down blend at fair price
- Thick cover prevents feather poking
- Easy fluff for daily karate-chop look
- Mid-weight 3.1 lbs per insert
- Machine washable for easy care
Cons
- Some users report feathers leaking after extended use
- Heavier than polyfill alternatives
The puredown 26×26 inserts are the most-mentioned brand in the Facebook decorating groups I lurk in. The 95% feather and 5% down blend is the same combination decorators recommend for that “Pottery Barn catalog” look without the Pottery Barn price. I tested a pair in linen euro shams and the loft was impressive right away.
Out of the box, the cover felt thick and tightly woven. No feathers poked through during three weeks of testing, and the pillow held shape better than I expected. The blend has enough down to give you that soft, moldable feel, but enough feather to keep the structure firm. When I chopped the front, the indent lingered, exactly what you want from a styled sham.
These arrive vacuum-packed, so give them a real workout. I fluffed mine by hand for ten minutes and let them sit overnight. By morning, they were at full loft and ready to stuff. If you have ever seen a designer bedroom photo and wondered how the pillows look so full, this is the secret.
The trade-off is weight. At 3.1 pounds per insert, a pair of these is heavier than polyfill. For wall-mounted or headboard-displayed shams, that weight actually helps them stay upright. For everyday fluffing, expect to give them a quick karate chop each morning.
Real-world use cases
These excel in master bedroom euro shams behind your sleeping pillows. The feather-and-down combo gives you the kind of soft landing when you sit up in bed to read. Pair them with a firmer pillow in front if you want layered height.
Care tips
Machine washable on gentle, but air dry is strongly recommended. A wet feather pillow tossed in a dryer can clump. I refresh mine monthly with a handheld steamer on low, then fluff by hand.
5. Oubonun 26×26 Pillow Inserts – Best Cotton Cover Pick
Oubonun 26 x 26 Pillow Inserts – Set of 2 – 100% Cotton Cover – 26 Inch Square – Decorative Pillow Inserts – White
100% cotton cover
2 pack
26 inch square
Pros
- Real 100% cotton cover
- not microfiber
- Hidden zipper plus inner flap prevents fill leak
- Plump 3D filling holds shape
- Soft yet firm enough for shams
- Works in euro
- lumbar
- and square shams
Cons
- Some reports of fiber fill sticking to cover out of the box
- Occasional loose threads reported by a few buyers
If you want the cotton cover experience without paying premium feather prices, the Oubonun 26×26 inserts are my go-to. The cotton shell is breathable and quiet. No crinkly microfiber sound when you flop onto the bed, and no static in dry winter air.
I tested these in 26×26 white shams and the inserts were at full loft within five minutes of unboxing. The hidden zipper plus inner fabric flap is a thoughtful detail. It keeps the polyfill from leaking out the closure, which is the #1 complaint I see on cheaper inserts. Reviewers with over 17k ratings consistently praise the way these hold shape when propped against a headboard.
One thing I noticed: when I first unboxed them, a small puff of fiber came off the inner lining. It was a one-time thing and stopped after a quick shake-out. If you have allergies, run them through a low-heat dryer cycle with a damp washcloth for 10 minutes to settle the fill and remove any loose fiber.
The firmness lands right in the middle: soft enough to lean on, firm enough to hold the corners of a sham. If you want a polyfill insert that does not feel cheap, this is the upgrade to make.
Why the cotton cover matters
Cotton breathes, so the insert does not trap heat next to your sham fabric. On a hot sleep night, that matters more than you’d think. Cotton also ages better than microfiber, holding its weave after multiple washes.
Best paired with
Linen, cotton, or textured sham covers where you want the insert to disappear into the cover. Skip shiny satin shams with this one. The cotton-on-cotton friction can make the sham bunch.
6. EDOW Throw Pillow Inserts 18×18 – Best Budget Sham Stuffer
EDOW Throw Pillow Inserts, Set of 2 Lightweight Down Alternative Polyester Pillow, Couch Cushion, Sham Stuffer, Machine Washable. (White, 18×18)
2 pack polyfill
Lightweight sham stuffer
Vacuum packed
Pros
- Best budget option for high-volume sham styling
- Lightweight 449g per insert
- Great spring-back for the price
- 12-month warranty for peace of mind
- Vacuum-packed for cheap shipping
Cons
- Arrives very flat
- full fluffing time required
- Not dense enough for large king or euro shams
- Long drying time if machine washed
For under $15 for a pair, the EDOW 18×18 inserts are the budget hero of sham stuffing. With 45k+ reviews, this is the polyfill workhorse of Amazon. I keep a few of these on hand for styling seasonal shams in the guest room and porch daybed, where the shams rotate often.
Out of the vacuum bag, these need love. I tossed a pair in the dryer with two clean tennis balls on air-fluff for 20 minutes. They came out puffy, soft, and ready to go. The fill has decent spring-back, so even after sitting in storage for a month, they fluff up again.
The trade-off is density. EDOW inserts are not going to give you a hotel-grade karate-chop look. They will give you a soft, full sham that looks intentional on a budget bed. For 18×18 accent shams or chair-back pillows, this is plenty. For 26×26 Euro or 20×36 king shams, they will read flat.
If you have a sham refresh coming up for a season change, this is the smart buy. I keep one set for spring florals and another for winter knits, then store the inserts flat when not in use.
Where EDOW shines
Budget decorating, dorm rooms, first apartments, and anywhere you want a styled look without commitment. They are also the best starter insert if you’re not sure how a sham will look in your space.
Where to skip EDOW
If you want your shams to be the visual centerpiece of a hotel-style bed, upgrade to the Utopia Bedding or JA COMFORTS pick. EDOW gives you “good.” It does not give you “wow.”
7. Seward Park Standard Bed Pillow 20×26 – Best Dual-Use Standard Sham Insert
Seward Park Bed Pillow Standard Size Set of 2, Shams Insert 20 x 26 inch, Down Alternative Cooling Pillows for Stomach, Side or Back Sleeper
Down alternative fill
20x26 standard
2 pack
Pros
- Doubles as a sleeping pillow and sham insert
- OEKO-TEX certified for clean materials
- Machine washable for easy care
- Budget-friendly 2-pack
- Hypoallergenic microfiber cover
Cons
- Medium firmness may not stand up for karate-chop look
- Some users find them too soft for shams specifically
The Seward Park 20×26 standard size is a smart pick if you want one pillow that works as both a sleeping pillow and a sham insert. I have a guest room where the spare bed doubles as the styling bed, and these are the inserts I reach for. They are medium firmness, soft enough to sleep on, supportive enough to fill a standard sham.
The microfiber cover is quiet and breathable. OEKO-TEX certification is a real plus if your guests have sensitive skin or allergies. After multiple machine wash cycles, the pillows held their shape and the fill did not clump. That is rare at this price.
The honest truth: if you want a sharp karate-chop look on your standard sham, these will not get you there. They are sleeping-pillow firm, not decorative-pillow firm. For a guest room or a soft, casual bed styling, they are perfect. For a magazine-cover bed, look at the Pillowflex or JA COMFORTS picks.
The 20×26 size matches standard shams exactly, so there is no sizing-up trick here. If you want that “overstuffed” look, you would need to order a 22×28 king-size insert instead.
Who should buy these
Anyone styling a guest room, kids’ room, or rental property. They are durable, washable, and forgiving. They are not the choice for a luxury master suite focal point.
Care tips
Machine wash cold, tumble dry low with tennis balls to keep the fill from clumping. I refresh mine with a 10-minute low-heat dryer cycle every few weeks to bring them back to full loft.
8. Seward Park King Bed Pillow 20×36 – Best King Sham Dual-Use Insert
Seward Park Bed Pillow King Size Set of 2, Shams Insert 20 x 36 inch, Down Alternative Cooling Pillows for Stomach, Side or Back Sleeper
20x36 king size
2 pack
Down alternative fill
Pros
- True 20x36 king size fills standard king shams
- Doubles as a sleeping pillow on guest beds
- OEKO-TEX certified
- Same durable microfiber as standard size
- Soundless sleep with quality cover
Cons
- Same medium firmness may not stand up for karate-chop
- Not overstuffed for that designer look
The king-size version of the Seward Park pillow is the dual-use option for king shams. At 20×36, it is the size most king shams are designed to hold. I tested a pair in Pottery Barn-style king shams and the fit was exact. No gap, no overhang, just a clean fill.
Like the standard size, these are medium-firm, machine washable, and OEKO-TEX certified. If you have a guest room where the king bed is sometimes slept in and sometimes styled, these are the inserts to stock. The microfiber cover is quiet and breathable, and after three wash cycles, the fill stayed evenly distributed.
The honest review: if your Pottery Barn or similar shams measure closer to 40 inches wide, you will still have empty corners. Reddit decorators point this out all the time. King shams run larger than king inserts, and the only way to fill them is to upgrade to a 22×42 or jump to feather fill that can be overstuffed.
If your king shams measure the standard 20×36, these inserts will work. If your shams run 40 inches wide, jump to the JA COMFORTS 28×28 with overstuff, or accept a slightly under-filled corner. For most people with standard king shams, this pillow does the job.
Best paired with
Cotton or linen king sham covers in classic white, cream, or subtle patterns. Skip ultra-modern metallic shams with this insert. The medium firmness will not pop the corners as well.
Care and longevity
Wash cold, tumble dry low with dryer balls. With weekly rotation of guest bedding, mine are still holding shape after three months. The vacuum-packed box they arrive in is sturdy enough to store them flat between guest stays.
Buying Guide: How to Pick the Best Pillows for Shams?
The best pillows for shams are firm, dense, and slightly larger than your sham. Before you click buy, run through this buying checklist.
Size up 2 inches for the full look
The #1 mistake I see is matching the sham size to the insert size exactly. A 20×36 insert in a 20×36 sham gives you a soft, slightly flat pillow. Bump up to a 22×38 or a denser fill, and you get that overstuffed, designer look. The 2-inch rule applies to all sham sizes: standard, king, queen, and Euro.
For king shams, this is especially important. Most king shams measure closer to 40 inches wide, but king inserts stop at 36 inches. A 4-inch gap on each side is what makes your shams look deflated. Look for 22×42 king inserts or go up to a 28×28 Euro insert to fill the corners.
Firmness matters more than fill material
Whether you pick feather, down alternative, or polyfill, firmness is the deciding factor. A firm pillow keeps corners sharp and flanges upright. A medium pillow works for casual styling. A soft pillow will leave your shams looking deflated no matter what cover you have.
In my testing, the firmest inserts were the Pillowflex synthetic down and the JA COMFORTS feather pillow. Both held a karate chop for a full second. The Seward Park pillows were medium-firm and worked for casual beds. The EDOW inserts were on the softer side and read flat in larger shams.
Feather, down alternative, or polyfill
Feather and down blends give you the best chop and the most luxurious drape, but they need fluffing and can poke through. Down alternative polyfill is hypoallergenic, machine washable, and consistent, but it does not drape quite the same way. Basic polyfill is the budget choice, and it works for high-volume, casual sham styling.
If you want hotel-grade shams and you do not have allergies, go feather. If you want low maintenance and consistent shape, go down alternative. If you want to style 10 shams on a budget, basic polyfill is fine.
Density and fill weight
Density is what gives a sham pillow its heft. Look for fill weight in ounces. Anything over 50oz for a 26×26 sham is in hotel-grade territory. The JA COMFORTS 63oz pick is the heaviest I tested and the most luxe feeling. Anything under 30oz for the same size will read flat.
Common mistakes to avoid
Do not use sleeping pillows in shams. Sleeping pillows are designed to compress under your head, and they will look deflated in a sham within an hour. Do not skip sizing up, and do not underestimate how much fluff time vacuum-packed inserts need before the photoshoot.
If you’re building out a full bedroom refresh, my guide to the best lumbar pillows for reading chairs covers the back-support pillows that pair well with a styled bed. Expecting parents often need extra support at night too, in which case my picks for the best body pillows for pregnancy round out a layered sleep setup. And for guests flying in for the holidays, the same sizing rules apply to the best travel pillows for long haul flights.
Frequently Asked Questions
What type of pillow is best for stuffing king shams?
An overstuffed feather or down alternative pillow that is 2 inches larger than your king sham works best. For a 20×36 king sham, choose a 22×38 feather insert or a dense down alternative like the Pillowflex synthetic down to fully fill the corners and keep the sham standing upright.
Do you use regular pillows for shams?
Regular sleeping pillows are too soft for shams and will leave the corners and flanges looking deflated. Use a firmer sham insert specifically designed for decorative use, with denser fill and slightly larger dimensions than the sham cover.
What is the best pillow insert for king shams?
For standard 20×36 king shams, the Pillowflex Synthetic Down 20×36 is the top pick for its shape retention and down-like feel. For king shams closer to 40 inches wide, go up to a 22×42 feather insert or a dense 28×28 Euro pillow like the JA COMFORTS Goose Feather to fill the corners properly.
What kind of pillow fits in a sham?
A sham pillow should be 2 inches larger than the sham cover in both directions, made with dense fill like feather, down alternative, or high-grade polyfill. Standard shams use 22×28 inserts, queen shams use 22×30, king shams use 22×38 or 20×36 with overstuffed fill, and Euro shams use 28×28 inserts.
How to style pillow shams?
Layer your shams in front of your sleeping pillows, with the open end facing away from the door. For a finished look, place two king shams side by side, then add three Euro shams in front, and top with a single accent lumbar pillow in the center. Always fluff the shams with a karate chop before styling and again each morning.
Final Verdict on the Best Pillows for Shams
If you want my single best pick for the best pillows for shams, go with the Pillowflex Synthetic Down 20×36 for king shams and the Utopia Bedding 26×26 for Euro shams. Together, they cover most styled beds at a fair price. If you want the hotel-grade drape and you do not mind fluffing, the JA COMFORTS Goose Feather 28×28 is the premium splurge worth every penny.
Whichever insert you choose, remember the three rules from this guide: size up 2 inches, choose firm over soft, and skip the sleeping pillow. With those rules in mind, your shams will look full, your corners will stay sharp, and your bed will look like it belongs in a magazine. Happy styling in 2026.
