Idle HippoHot Tub Booster Seat, Weighted Hot Tub Pillow with Powerful Non-Slip Suction Cups, 4D Air Mesh Ergonomic, Booster Cushion, Quick Dry Spa Pillow for Indoor Outdoor Hot Tub

These are great! Made well, lots of cushion and big enough to fix my booty! I use these in my inflatable hot tub. Hang to dry and good to go!

I've tried some other types of boosters (for in the hot tub), and have been disappointed. THIS one is exactly what I want!The suction cups make the booster stay in place without any movement! (In fact, the suction cups are a tad annoying, only because they stick so strongly... it is a tad tedious to pull it out because you have to un-suction each suction cup one at a time. But that's my only complaint; and it's worth it, since it does stay put when I need it to!)The seat is high enough to give me the boost, but not so high it's obnoxious. It's also very comfortable - I actually forget I'm even sitting on it.I like the small loop on the side. I hang it on a hook when I get out of the hot tub, and it dries very quickly.

Very well manufactured, of good quality in materials and workmanship. The suction is all but undefeatable. Thank goodness for the tiny tabs to release the cups. The tabs could be bigger, it takes a bit of searching with my fingertips. The pillow will slide in a tub. It is not the fault of the pillow, the suction cups do not prevent horizontal movement. This has been a bit of an advantage for me. I can slide forward and adjust faucets, etc. without leaving the pillow. Then back to my relaxing position.

This is very comfy but it does not stick to the bottom of the hot tub. Every time I go to get in, this is floating on top of the water.

Actually I use this for my walk-in tub. It fits very nicely, adheres well, is comfortable and dries pretty fast. Nothing not to like!
