Review: Good Quality pillow - Wow! Great pillow! Well sewn! Firm! Better than I expected. Super comfy. I bought to add to bed for a decorator pillow but I keep grabbing it to use to lay on. It’s soft and comfy but firm. I’m probably going to have to buy more.

### ⭐⭐⭐⭐⭐ Nice product
*by A***R on January 12, 2026*

A nice substitute for down pillow inserts. It is soft and flexible, mimics down, at an affordable price for such a large pillow size. I’m very happy

### ⭐⭐⭐⭐⭐ Good Quality pillow
*by C***I on January 7, 2026*

Wow! Great pillow! Well sewn! Firm! Better than I expected. Super comfy. I bought to add to bed for a decorator pillow but I keep grabbing it to use to lay on. It’s soft and comfy but firm. I’m probably going to have to buy more.

### ⭐⭐⭐⭐⭐ Great insert
*by E***T on November 16, 2025*

This is a great pillow insert. I like the look/feel of down but the poking feathers are really annoying and they just mush and stay mushed—this alternative one is great! It’s heavy, soft, fluffy, chops well, and seems like it’ll be sturdy and hold up to couch naps and dogs. I went with the actual size of the cover at first per reviews and they were a little too small, so I wound up sizing 1 up and they’re perfect. 22x22 in a 20x20 cover and 24x24 in a 22x22 cover. Easily the nicest insert I’ve bought! Will be a repeat buyer as I get more pillows.
