Bought this for wfh during quarantine. My back went out due to sitting in a dining chair, and I knew I needed a different solution. I chose this due to good reviews and I wanted something tall to use with a standing desk. Turns out this almost works and was very easy to put together - I was particularly happy with the clear labeling of all the parts, and the adjusters work great. However, it’s a touch short for my needs even fully extended (not really the fault of the chair) and I wish it had more back support, but overall a good purchase.
