Customers find the product functional and helpful for elevating seating in hot tubs, with some noting it works well as a neck cushion. However, there are significant concerns regarding stability, as the seats tend to float and move, making them difficult to keep in place even when occupied. This lack of stability also impacts ease of use, with some reviewers finding them unusable or impossible for children to use. Opinions on value are mixed, with some finding the quality acceptable for the price, while others consider them a waste of money due to their instability. Some users do find the product comfortable, particularly for shorter individuals.
