Size: 22 Inch by 22 Inch
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.

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.

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

Best insert I have tried. Higher quality brand. I will be buying more. Comfortable, good support and fills out the cover. Looks more professional.

These are the best pillow inserts I have ever purchased. I love home decor and I especially love high quality Pottery Barn, Restoration Hardware, Crate & Barrel, etc. bedroom looks. I try to mix high and low since you don’t need to spend top dollar on everything. I always felt like my bed was lacking even though I had Pottery Barn & West Elm bedding and even though I had good quality Euro pillows it didn’t look as nice as photos I’d see online of other interior designed bedrooms. THESE inserts make your bed look amazing & more designer. These inserts really made a difference in the look of our bed. They are very heavy, they hold the “karate chop” well, and you won’t have to worry about them going flat because of the down alternative filling. I had originally purchased a set of 2 and thought maybe I’d use my old 3rd Euro pillow insert but the difference was so big, I had to buy the 3rd insert. The Pillowflex inserts look that much better. Just full and designer. I can’t wait to buy a few more for my couch now. I purchased the 26” Euro pillows and used 24” pillow covers to make sure they would look full. Shipping took longer than normal but it was worth it. Highly recommend and I will continue to purchase this brand for all pillow inserts.

I bought a bolster size sham from minky couture 42x14, put this pillow insert size 46x16 in it, fits great. This pillow insert is great quality but really pretty soft and easily squish-able. Glad I sized up.

Heavy, squishy, high quality, - BUT ONLY ONE INSERT. This one is absolutely my fault, but I assumed this was a price for 2 inserts and when it came found it was one, so if you’re like me be warned. For one insert this price is HIGH but it is very good quality. I was going to return it and buy a two pack elsewhere but Amazon charges you to return this product…still 4 stars, 5 if it wasn’t so expensive. Otherwise this is a great alternative to down without it being down alternative, karate chops and is heavy weight, but doesn’t go flat like down does.

Best pillow form I own. I needed a very strange size. So I just happened to find this. They’re nice and full. Keep in mind they’re very heavy. I am in a wheelchair and it can be a little challenging to make the bed, but it is worth it because the pillows are very nice looking. I liked them so much. I purchased king pillows for shams. This is the brand I will purchase in the future.
