How to choose throw pillows
Updated June 2026Independently researchedNo paid placement.
The best throw pillow for you depends on where you plan to use it and how much maintenance you’re willing to do: go with a down-alternative insert for a soft, machine-washable option, choose a dense foam core for structured couch support, and pick a cover fabric that matches your lifestyle, velvet for cozy, or performance linen for spill-prone homes.
What size of throw pillow should I buy?
The size of your throw pillow should first match your sofa or bed. For a standard couch, 18 by 18 inches or 20 by 20 inches are the most versatile; they sit comfortably on seat cushions without overpowering the back. If you have a deeper sectional or a king-sized bed, 22-inch squares or even 24-inch squares can look intentional and generous. Smaller pillows, like 12 by 20 or 16 by 16, work well in layered groupings or on accent chairs. Consider the scale of your furniture, not just the visual proportion. A low-profile mid-century couch can be overwhelmed by a 22-inch pillow that blocks the armrest. Conversely, a plush, oversized sofa can make a 16-inch pillow look like a tea coaster. Owner reviews and styling experts often suggest starting with a pair of 20-inch pillows and then adding a smaller lumbar or square for depth.
What fill material is best: down, down-alternative, or foam?
Down inserts offer the softest, most luxurious feel, they squish nicely and conform to your shape. The trade-off is that they need daily fluffing to hold their shape, and real down can trigger allergies in some people. Down-alternative fills (usually polyester fiber clusters) mimic the softness of down but are machine-washable in most cases and hypoallergenic. For a premium feel without the upkeep, many reviewers recommend a high-quality down-alternative insert with a plush baffle box construction. Foam or poly-fil cores give a structured, firm look that stays crisp even after hours of sitting. They are ideal for pillows that serve as back support or for a more tailored, decorative look. The downside is that foam cores can feel stiff and less cuddly. For the best of both worlds, some brands offer a blend: a foam core wrapped in a down-alternative layer. Consider how much use the pillow will get, if it’s purely decorative, go with a firmer fill; if you’ll lean on it daily, a softer fill is more comfortable.
Which fabric cover is most durable for everyday use?
Performance velvet, cotton twill, and linen blends are three popular choices for long-lasting throw pillow covers. Cotton twill is a workhorse: it resists pilling, washes well, and has a classic, slightly textured look. Linen blends bring a relaxed, breathable feel but can wrinkle easily and may show wear faster in high-traffic areas. Velvet (especially performance or velvet made from polyester) feels luxurious and hides pet hair more than you might expect, but it can snag sharp jewelry or claws. For homes with kids or pets, look for covers labeled as “performance fabric” or “indoor-outdoor” material. These are often solution-dyed acrylic or polyester that resists stains, moisture, and fading. They feel a bit crisp but get softer with washing. In published roundups of durable pillow covers, performance polyester and tightly woven cotton blends consistently earn the highest marks for longevity. Avoid silk or delicate weaves if the pillow will be handled daily.
What closure type is most convenient: zipper, envelope, or knife-edge?
Envelope closures (also called overlap closures) are the easiest for everyday use, you can pull the cover off and toss it in the wash without wrestling with a zipper. They are also the most forgiving if the pillow insert is slightly too large. The drawback is that envelope flaps can gap slightly if the pillow is very full or you sleep on it, revealing the insert beneath. For a cleaner, more tailored finish, zippered covers are the gold standard. The zipper should be hidden along a seam, not on the back, to keep the look polished. Knife-edge pillows (a square shape without a box border) are a specific construction style rather than a closure, but they often have an invisible zipper. They look modern and neat but can feel less plush than a boxed-edge pillow. If you plan to swap covers seasonally or wash them often, a zipper with a generous tape length is easier to manage than a tiny zipper that catches fabric. Many experienced decorators prefer zippered covers because you can add or remove filling to get the perfect plumpness.
How many throw pillows should I put on my couch or bed?
For a standard three-seat sofa, a good starting point is three pillows: two larger squares at the ends and one smaller lumbar or accent in the center. This gives a balanced, welcoming look without crowding the seating area. If you prefer a more minimal style, one or two 20-inch pillows on the ends can be enough. For a bed, the usual formula is two standard pillows, two euro shams, and then two or three decorative throw pillows in descending sizes. That arrangement works well for queen and king beds. There is no strict rule, but oversaturating a small loveseat with five pillows will shrink the usable space. On the other hand, a large sectional can carry four or five pillows if they are distributed across the different seating zones. The key is to leave at least some clear seating for actual sitting. Owner feedback often suggests that the number of pillows should feel “just right” for your household’s daily use, more pillows mean more fluffing and more storage space for resting them when not displayed.
Can I mix and match different pillow shapes and patterns?
Absolutely, and that is often the secret to a styled look. Start by choosing a color palette of two or three hues, one neutral, one accent, and one metallic or pattern. Then mix a solid pillow, a subtle geometric, and a larger-scale floral or abstract. Varying texture is just as important as color: combine a smooth linen, a nubby knit or faux fur, and a glossy velvet or silk velvet. For shapes, pair a standard square with a rectangular lumbar or a round bolster to break up the visual monotony. The safest approach is to let one pillow be the focal point (the bolder pattern) and keep the others toned down. If you are unsure, try two pillows in the same color family but different patterns, like a stripe and a small-scale dot. Many interior designers suggest the “rule of three”: three different textures or patterns that share one common color. That keeps the arrangement cohesive even when the pillows themselves are quite different. Reading reviews and looking at customer photos of pillow sets can give you a good sense of which combinations work before you buy.
Frequently asked questions
Should I buy a pillow insert and cover separately or as a set?
Sets are often a better value if you like the cover and the fill together. But buying separately gives you the freedom to choose a high-quality insert and a cover that exactly matches your decor. Many owners prefer separates because the insert can last longer than the cover, and you can swap covers seasonally.
How do I keep throw pillows from going flat?
Fluff your pillows daily and rotate them. For down-blend inserts, give them a good shake and a few punches to redistribute the fill. If a pillow seems deflated, try a low-heat tumble in the dryer with a clean tennis ball or dryer balls to restore volume. High-quality inserts will hold their shape much longer than budget ones.
What is the best way to clean throw pillow covers?
Always check the care tag first. Most cotton and linen covers can be machine-washed on cold and tumble-dried low. Velvet and silk are often dry-clean only. To extend the life of any cover, use a mesh laundry bag and skip fabric softeners, which can damage fibers and reduce stain resistance.
How can I tell if a throw pillow insert is well-made?
Look for a high fill power (for down) or a high gram weight (for synthetic), but avoid trying to compare exact numbers across brands. Instead, read owner reviews that describe the plumpness and loft. A good insert will have a baffle box construction that prevents the fill from shifting to the corners, and the seam should be sturdy and double-stitched.
Are feather pillows safe for people with allergies?
Feather pillows can trigger allergies because they contain dust mites and dander. Hypoallergenic down-alternative pillows are a safer choice for allergy sufferers. If you prefer down, look for certified allergy-friendly brands that wash the feathers multiple times, but even then, some people react. A tightly woven cover (like a high-thread-count cotton) can help contain allergens.
