The wedge pillow came in an unbelievably small box, but when opened, it started “growing”. Within two days, it was to full size, except for one corner, and after a week, that corner has still not popped out! It really doesn’t affect its use tho, because it is plenty wide as is, about 23” square. With approximately a 7” rise, it is a good base to use as a post-surgery pillow. The memory foam wedge pillow comes in a removable cover which is washable, and it works equally well for head or legs, where ever you need a gentle incline.
