Overall this is a good sturdy and comfortable chair. The lumbar support could use a bit longer and adjustment rail and it just fits me at the top of the rail so anyone taller that 6' may not be able to get it positioned quite right. The lowest height is a bit high for people who are short-legged as the lowest height is about perfect for me. the build quality is solid and the fabric seems durable. I like the ridge on the base above the castors. I almost always have my foot resting on it and it does provide a comfortable resting position. the multi-angle lock is great for the back when you need to adjust your position but still want solid support!
I would say this is a low end option for HM chairs you get most features I like the lumbar support. Everything is about right the only downside is the quality of mesh is not that outstanding but that's what you pay for. Still highly recommend it.
Chair is reasonably comfortable in the seat arms are very limited in motion. The hydraulic unit on my chair does not stay at its setting so while I raise the chair it lowers incrementally while sitting. Infuriating. Replacement part is back-ordered two months.
