FAQ: Pillow Inserts
What size pillow insert should I use?
To achieve a full and plush look, choose an insert that is 1 to 2 inches larger than your pillow cover. For example, if your pillow cover is 18×18 inches, go for a 20×20-inch insert. This helps fill out the corners and prevents a saggy appearance. However, if you prefer a softer, more relaxed look, a same-size insert will work.
What’s the best material for pillow inserts?
The right material depends on comfort preferences and allergies. Down and feather inserts offer a soft, moldable feel but can trigger allergies. Synthetic fills, like polyester or microfiber, are hypoallergenic and maintain their shape well. Foam inserts provide firm support, making them great for lumbar pillows or decorative arrangements.
How do I make pillow inserts feel softer?
If a pillow insert feels too firm, try fluffing it regularly to redistribute the filling. Down-filled inserts can be kneaded and shaken to loosen the feathers. For polyester inserts, removing a small amount of stuffing can help. Over time, daily use naturally softens the material, making it more comfortable.
Can pillow inserts be washed?
It depends on the fill type. Down and feather inserts should be washed with mild detergent in a front-loading washer and dried on low heat with dryer balls to maintain fluffiness. Synthetic inserts are usually machine-washable, but check the label first. Foam inserts should only be spot cleaned, as soaking can damage their structure.
How long do pillow inserts last?
A good pillow insert lasts 2 to 5 years, depending on use and material quality. Down inserts tend to last longer if fluffed daily and kept dry. Polyester and foam inserts may lose shape over time, requiring replacement sooner. Washing inserts properly and using protective covers can extend their lifespan.
Why does my pillow insert feel flat?
Pillow inserts flatten over time due to compression from daily use. To restore fullness, try fluffing it by hand, putting it in the dryer on low heat with dryer balls, or adding extra stuffing. If it no longer holds shape despite fluffing, it may be time for a replacement.
Are pillow inserts necessary?
Yes! A well-chosen insert enhances the comfort, shape, and durability of your pillows. It prevents sagging, offers better support, and allows for easy seasonal updates—just swap out the covers for a refreshed look.
