It’s too tall as a piano bench by a good 4 inches even at minimum setting.
The cushion on it is also so deep that it feels a bit wobbly like sitting on a balloon . The other similar version is much better as it is firmer, cheaper, easily collapsible but has fake leather which gets sweaty. It is still far too tall to use for a piano bench. Thomann offered me a refund on it however and I still use it around the house. Probably should be advertised for guitar players or other instrument as it’s a decent seat
