I bought three of these to fit under my island, and they work very well. Only v minor issue I have is that they are quite slippery unless you ensure your feet are on the step, so I may purchase something appropriate to glue / affix to each seat. Damper is very strong, so you need to sit on it to force the seat down should you raise it too high - not really an issue.
