Spa and Hot Tub Booster Seat, Inflatable Bathtub Massage Cushion, Relaxation Massage Mat with Suction Cups, Soft Back Support Bath Spa Pad for Adults Elders Kids at Home Spa&Rest

Easy to inflate these with a hose, although not that easy to get them completely full, when first putting in the spa they seemed fine, and stayed on the bottom, however the next day they had floated to the top. The suction isnt good enough to hold them, i assume it is because there is a little air in them still, but i found it impossible to get any more water in !Not a huge problem for me, they are fine to sit on, mainly used by my wife and son as they are are little shorter and wanted to have their heads a bit higher in the spa!

Bought when my hot tub was full with water and it just would not stick to the bottom. kids did have fun however trying to balance on it as they floated about. Needs to be left in hot tub to get to temperature as I first sat on it freshly filled and boy was it cold :-)

No good for using in hot tub won't stay on bottom so can't sit on them. Filled with water helped that but don't thi k they will last long

If I can manage to sit on one these are very comfortable but although have filled with water , it is impossible to get them to remain adhered to the tub , they continually float to the surface .

Not happy would not recommend do not stay at the bottom with the suction feet

Nightmare to fill with water, doesn’t suctioning very well but does the job

Bit a lot of good didn’t stay under water I. Hot tub! Waste of money

This just would not stick to the base of my hot tub
