This is a very sturdy chair. The suction cups on the legs ensure the chair will not slip. Only one problem and it has nothing to do with the chair itself. If your bathtub is not wide, you will have to put the chair sideways. But it still works great.
The first chair I ordered came without the bag of screws. We contacted the manufacturer, explained our need for the chair asap and they said to keep what they had sent and sent another whole new complete box. Excellent customer service and a very sturdy chair.
I am very pleased with this chair. It is well made and was very easy to assemble. I made of aluminium and hard plastic, it is very light and you could tip over if you lent back too far, but this is an observation rather than a criticism.
Fits in shower stall very nicely, makes for a safer environment easy to assemble, high quality suction cups on legs make for a no slippage while showering
