Best Throw Pillows: Features, Fit and Trade-offs

Choose a feather-and-down-blend insert with a cotton or linen cover if you want a plush, sink-in look; choose a polyester-fill insert with a washable cover if you want easy care and a lower budget; and choose velvet or textured covers if you want a decorative accent, since the cover and size usually matter more than the brand name.

At a Glance: Throw Pillow Types Compared

Size and Fit Rules

The most common sizes are 16, 18, 20 and 22 inches square, plus lumbar shapes around 12 by 20 inches. A common styling tip is to choose an insert one to two inches larger than the cover so the pillow looks full when covered. An 18-inch cover filled with an 18-inch insert looks tight and holds a clean shape, while a 20-inch insert in an 18-inch cover looks very plush.

On a standard sofa, a mix of 18- and 20-inch squares plus one lumbar is a flexible starting set. Large 24-inch pillows suit deeper sectionals and beds, while small 14- or 16-inch accent pillows fit chairs and benches.

Fill: Feather, Down or Polyester?

Feather and down

This fill is soft, forms around your back and can be fluffed to restore shape. The downside is that quills can poke through cheaper casings, and anyone with allergies should avoid it. Check the maker’s description for the feather-to-down ratio and for a down-proof casing.

Polyester fiberfill

Polyester is inexpensive, easy to wash and often marketed as a hypoallergenic alternative. It does flatten sooner than feather, so you may need to replace the insert after a few years.

Memory foam and shredded foam

Used in firm decorative or back-support pillows. Shredded foam can mold to your back but may feel dense on a sofa.

Covers: Fabric and Closure

Cotton and linen

Natural fibers are breathable and easy to find in neutral and printed styles. Linen wrinkles but looks relaxed and casual.

Velvet

Soft, dressy and good at hiding wear, though it can attract pet hair and may crush in places. Check whether the cover is machine washable.

Textured and woven styles

Chenille, bouclé and knit covers add depth. They tend to snag if pets scratch, so consider this if you have cats.

Boho and patterned covers

Tassels, embroidery and tufting add personality but may need gentle washing or dry cleaning.

Closure

Hidden zippers give a clean look and secure fit. Envelope closures are easy to make and remove but can gape slightly with a loose insert.

Styling Notes

• Mix at least two textures and two patterns with a solid or two for balance.
• Use odd numbers, such as three or five pillows, for a relaxed look on a sofa.
• Pick colors from a rug or art piece to tie the room together.
• Keep fragile or dry-clean covers for display pillows and use washable ones where children or pets sit.

Care Notes

Remove covers before washing. Wash inserts only if the label allows, and dry them thoroughly to avoid mildew. Fluff feather pillows regularly. If anyone in the home has allergies, a washable cover and an insert with a tight-weave casing can help, but follow the maker’s guidance and speak to a doctor about allergy concerns.

Budget Tiers

Budget

Value inserts from Utopia Bedding and similar brands in polyester fill, paired with inexpensive covers, cover most needs. Expect inserts to flatten sooner.

Mid-range

Feather-blend inserts and better covers from home retailers last longer, hold their shape and look more polished.

Premium

Designer covers, hand-embroidered pieces and down-filled inserts are in this tier. Choose these for a showpiece living room where the look matters most.

Pick X If… Decision Table

Alternatives to Consider

• Floor cushions: Larger, good for casual seating or kids’ spaces.
• Bolsters: Cylinder-shaped accent pillows for beds and daybeds.
• Folded throw blankets: Add texture and color without buying more pillows.

How to Build a Pillow Arrangement

Start with the largest pillows at the back, usually 22 or 24 inches, then layer smaller squares and a lumbar at the front. Repeat one color or pattern across at least two pillows so the set looks intentional. For a bed, use sleeping pillows first, then Euro shams, then two or three decorative pillows.

Common Mistakes

Buying covers and inserts in the same size

This creates a flat, floppy look. Size the insert up by an inch or two to fill corners.

Choosing delicate covers for daily-use seating

Silk, embroidery and heavy beading look great but can snag or stain. Use durable cotton, polyester blends or performance fabrics where children and pets sit.

Ignoring cover care

Some covers are dry-clean only. If you want to wash covers often, look for machine-washable cotton, linen blends or polyester.

Skipping insert quality

A beautiful cover over a thin, lumpy insert looks sloppy. A good insert holds its shape and has tight stitching around the edge.

Outdoor and High-Use Spaces

For porches and patios, look for fabrics the maker states are weather- or fade-resistant. Even so, bring cushions inside during heavy rain or when not in use. Quick-drying fills help prevent mildew. For family rooms, choose tightly woven fabrics that resist pet hair and spills, and consider zippered covers so you can wash them regularly.

Frequently Asked Questions

What size throw pillow should I buy?

The most versatile sizes are 18 and 20 inches square. Add a 12 by 20 inch lumbar pillow for variety. Pick an insert one to two inches larger than the cover for a fuller look.

Do I need to buy inserts separately?

If you buy covers only, yes. Many decorative pillows come pre-filled, but the fill may be basic. Buying inserts and covers separately lets you upgrade the fill and change the look.

How many throw pillows should a sofa have?

There is no fixed rule, but three to five pillows suits a standard sofa. Use odd numbers for a relaxed look or pairs for a formal one.

How do I wash throw pillows?

Remove the cover and follow its care label. Wash inserts only if allowed, use a gentle cycle and dry completely. When in doubt, spot clean.

Are feather pillows safe for allergy sufferers?

Feather fill can aggravate allergies for some people. Polyester inserts with washable covers are a common alternative. Talk to your doctor for allergy advice.

How long do throw pillow inserts last?

It depends on fill and use. Polyester can flatten within a few years, while feather-down inserts can be fluffed back into shape and often last longer.
