So far it’s going great. It hasn’t lowered itself automatically due to weight. However I have only had the chair for a week so rating it this soon isn’t enough time to rate it correctly.
After spending over an hour testing all of the chairs in the store my wife and I found this one to be the best. It is very comfortable work chair with a well padded firm seat. Some chairs were more comfortable when reclining back in them but the fact is for us we sit upright leaning forward while working. There is an adjustable lumbar section which offers great lower back support. Chairs we had purchased in the past with imitation leather arms wore out extremely quick and looked bad just after several months. There were some on display in the store that the stitching was coming undone!! The arms on this chair are are what I would call thick soft vinyl rubber like material and adjustable. The mesh seat and back keep you cool during long periods of sitting. One thing is if you are a large person this chair may be too small for you. I weigh 190 and am 5'10". When sitting upright my lower back is right up against the lumbar section which is great but a big boy may feel pushed too far forward. Over all they are just what we wanted and expect them to last a long time. There were other much less expensive chairs to choose from. Don't cheese out trying to save a few bucks on something that you will spend a good part of your day sitting in that will not last very long. You get what you pay for.
I am glad that I purchased this chair as I was getting tired of my old office chair that was falling apart. I like the fact that it not only has a mesh backing but also a mesh seat so that there it is less likely to trap sweat and other smells in the seat cushion like some office chairs. The rest of the functionality is pretty standard to most office chairs with adjustable arms and reclining backing. I was debating bout buying the more expensive WorkPro office chair that was around ~$400 but ultimately went with this one as it seemed lie it would get the job done at a fraction of the cost with mesh seating.
Working from home I was ruining my back sitting on a wooden kitchen chair so this is quite an improvement. Pretty easy to assemble and looks very spiffy.
