Works great. Exactly what we needed.

I mostly like this chair but the ring tension piece is plastic and broke so now the ring is just sitting at the bottom useless.

The adjustability is what drew our attention, my welder is able to position himself as needed to get the job done, so far so good.

Chair arrived on time, fairly easy to assembly, nice heights, and very adjustable..good build quality. The footstool isn't that usable at the lower heights but is okay as you lift it higher.
