## Description

desertcart.com: Pillowflex Synthetic Down Pillow Insert - 16x16 Down Alternative, Ultra Soft Throw Pillow, Small Couch Sham Bed Sleeping Pillow - 1 Decorative Accent Form : Baby

Review: Buying more in different sizes! - I’m very happy with the Pillowflex Synthetic Down Pillow Insert (22x22). The fill is soft, fluffy, and provides a nice balance of comfort and structure. It has that “down-like” feel without being too flat or overly stiff, which is exactly what I was looking for in a decorative throw pillow. One of the biggest positives is how well this 22x22 insert fits into a 20x20 pillow cover. It gives the pillow a very full, high-end look—no sagging corners or underfilled appearance. The result is nicely plump and polished on the couch. The quality feels solid, and it holds its shape well after fluffing. My only small reason for four stars instead of five is that it does compress a bit over time and needs occasional fluffing to keep that full look. Overall, this is a great value pillow insert—comfortable, soft, and perfect if you want a fuller look when sizing up inside a 20x20 cover. I would definitely buy these again.
Review: Great bed pillow - This pillow is great! It's just what I was looking for. Soft and fluffy like a good bed pillow, but bigger and fuller. I've got these on my bed now as my sleeping pillows, also great for sitting up in bed.

This pillow is great! It's just what I was looking for. Soft and fluffy like a good bed pillow, but bigger and fuller. I've got these on my bed now as my sleeping pillows, also great for sitting up in bed.

### ⭐⭐⭐⭐⭐ Quality pillow inserts!
*by L***G on February 26, 2026*

I just received my pillow inserts and I am so impressed. They are beautiful and heavy. The quality is so good. They are not down but they have a substantial feel. They are also choppable which is something I was looking for. I got a 27” for a 25” pillow cover. They were a little pricier than I wanted to pay but totally worth it in my opinion
