Purchased the chair in June 2019 and still highly satisfied. It's comfortable very durable and lasting well. Mechanics still working like new and chair surface has not stretched. The padding on the left armrest did crack. Called to inquire about purchasing a new one. Warranty covers that and a new one will be sent at no cost.
The lumbar support bar arc is too sharp the highest setting is too low and the adjustment mechanism slips. Either the bar needs to be more adjustable (e.g. angle height) and the slope gentler or it needs to be removable. Otherwise I think it's a great chair.
The chair was pretty comfortable it breathed well being made of mesh. It leaned back a bit too far for my taste and only had 3 settings: straight all the way back or slightly tilted. The biggest problem is how it broke within 6 months. The back of the chair which is made of cheap metal completely broke near the screws. Very unsatisfied by the quality.
