After about a year the cylinder started to break through the skirting and ended up resting on the floor which makes it not very useful anymore. I liked it up until then. The skirting on the legs is cracked where the cylinder sits so a replacement cylinder would just fall through.
Got this for husband. He is 6'2 210 lbs and it fits him great. The back support is much more supportive than we thought it would be and better than either of our current chairs. He tends to sweat on his lower back. The mesh provides him with a much needed comfort in temperature regulation. He was also a foot sitter. The design of this chair does not allow for comfortable foot sitting. Which his veins and ankles will thank him for. I got this chair on sale around $130 and pleased with the purchase.
The seat is not long enough for me or the lumbar support juts too much forward. I like the seat to be big enough so that the front edge of the seat touches the back of my knees. Otherwise it is a sturdy task chair.
II bought this chair to replace one that was not mesh-backed and kept lowering through out the day. It was easy to assemble and I did not have to attach the arms in order for it to hold together like some chairs. It has adjustable lumbar support and is very comfortable to sit in for long periods of time. The only thing I do not like it that it does not raise up high enough for me to be at an ergonomically correct position for typing. I am tall and like to have my desk a little taller than most so I have legroom under the desk. I am correcting the height issue by making a cushion that will raise me up to a good height for my desk.
This was a great chair for about 3.5 months until the armrests started to break at the seams of the padding it became very uncomfortable because of the padding poking into your skin or clothes. It has also developed some amount of leak in the cylinder and causing you to sink to the floor at a very slow pace. It has also started creaking very loudly so much so that if I'm talking to someone and I lean back they can hear it. I'm 6'3 225 and use this chair to game and do other normal things at my desk but after 3.5-4 months of usage these things have just started to develop I tried WD-40 on for the creaking and sprayed every bolt that I could see and the creaking persists. All in all I would recommend this chair if you put 3-5 hours a day in it but would recommend something more expensive if your are going to use it more.
