It says its suitable for filling with water but the water leaks out. Will fill it with air and just use as a float or head cushion. Very disappointed.

What genius designed an inflatable cushion to be used underwater??? Even when only partially inflated (i.e. Less than 10%) it is impossible to sit on it in the spa as it tries to float and tips you off. HOWEVER........there ia a simple solution: don't fill it with air, fill it with water! It then acts like a waterbed and gives you a veru comfortable cushion which stays in place on the bottom of the spa.

These look good but again due to not using hot tub i haven’t used them

Great product for the hot tub, beats sitting on the floor. Easy to use and arrived in good time, well packaged and app easy to navigate round.

Got it for a seat cushion but realized that it is too floaty. Works great as a tray though.
