This is great. It is adjustable height which you can adjust to your liking.

I like it and prefer the higher height, can be bent forward and backward as an ankle exercise 👍

A little too flexible due to plastic, but works ok

It's a bit pricy but meets my needs.

confortable, j'ai bien le niveau d'auteur pratique quand on est petite

Serves its purpose...relatively comfortable and it does help with sitting properly...keeping the back straighter. Like that the height can be adjusted and the it tilts.
