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.
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.
