Review (5/5): A great buy!
I've taken many nice baths with this pillow already!
There are many pluses to the pillow! I've had blow up pillows before - they try to float above the water line, which can be a problem depending on the depth of your tub; and they can deflate while you are using them. I've also had pillows which are more like pillows - the stuffing is soggy and weighs them down, the water they soak up gets cold and can run down your shoulders; and worst of all, the water they hold on to can cause them to mold!
This pillow takes the best parts of both types of pillows and eliminates the cons! The pillow is a rubbery material with a nice plush top side. it doesn't soak up water or hold onto water. But it's stuffed, so it has a nice cushion for your neck and the base of your skull. It isn't inflated, so it doesn't deflate or try to float. It'll float if you have it detached, but it comes with 4 large and strong suction cups to hold it in place on the tub wall.
I also love the fold in it so that it contours to the edge of the tub. This has been fantastic and has me spending more time reading and lounging in the tub!
