Tried to put in a 20x20 pillow insert (which is supposed to be done to make them look fluffier) and the zipper broke cleanly. The hole is very narrow. I was able to insert 18x18 and everything was fine, but you have to be very careful when doing this. The material isn't the softest for sleeping, but they're only good for lounging or behind your back.
