Buying Guide

Choose the right size

Match insert dimensions to your pillow cover—common sizes here include 14x22, 20x20, 26x26 and lumbar lengths like 14x36 for a proper fit and fullness

Consider fill material

Down-alternative fills provide hypoallergenic loft and consistent shape while cotton-covered or synthetic fills offer firmer support and easier care

Check cover construction

A tightly woven cotton cover helps retain fill and reduce pilling; look for reinforced seams on inserts used in frequently handled pillows

Decide on firmness level

Higher-fill density or synthetic down inserts keep a plumper look for decorative pillows, while softer down-alternative inserts work better for lounging

Buy multi-packs for matching sets

Sets of two or more inserts simplify styling and ensure consistent loft and appearance across a sofa or bed ensemble
