Review on 🛋️ Acanva Soft Throw Pillow Inserts for Couch - Hypoallergenic Polyester Stuffer, Square Form Washable Cushion Euro Sham Filler, 22 Inches - Pack of 2, White by David Hodgson

One of these was vacuum packed, the other - in the same packaging - was fully flared. I ordered 20" inserts for 18" pillowcases and it was difficult to fit the extended one into the cover. I never managed to get it fully working in the corners. Vacuum packed worked much better, but be aware that it expands as soon as it's taken out of the box (although it wasn't fully expanded until the next day). I wouldn't advise opening it until you're ready to use it. The 20" inserts filled out the 18" lids nicely, giving them a plump but not overstuffed look. The pillows feel firm but not stiff and boast soft support when you place one behind your back.
