Doesn't inflate
I don't know if I didn't read the product description well enough, but this in NOT an inflatable pillow. It has a decent cushion and the rest just keeps your back from touching the bathtub. It was surprisingly comfortable, however the suction cups don't suction well enough to keep it in place. It is great as long as you are leaning against it, but since it doesn't suction well, it slips if you move.  It does have hook that you can hang on your shower to let it dry thoroughly and I love that part of it. I will keep using it, because I have it and have already used it in the bathtub, but I wouldn't buy it again.
