Sophia R. ★★★★★

The 20-inch size is a perfect match for my covers, and the duck feather fill gives it that plush, weighty feel without being lumpy. It plumps right up after a quick fluff, and the shape holds up through a full night of use. Honestly, best inserts I’ve tried, hands down.

Carter H. ★★★★★

The duck feather fill gives these inserts a real heft that makes my sofa look styled instead of saggy, and they’ve kept their square shape even after daily use. I bought two to swap between covers, and the fullness is exactly what I wanted for a plush, expensive-feeling seat.

Sophia ★★★★★

It fluffed right back up after a couple of days in the dryer, and the duck feather filling gives it that heavy, plush feel you only get from real down. It’s a perfect snug fit inside my 20x20 cover with zero sagging corners after a week of daily use.
