Bought multiple for our office and after one month of use two of the four are squeaking with every movement. It is unbearable to listen to all day we will be replacing them. Don't recommend for long periods of use.
If you haven't had a mesh office chair before you might be surprised how comfortable they are. I was given a mesh chair at work and really liked it. so I bought this one for home. The mesh seat seems to distribute weight more effectively and eliminate pressure spots from extended sitting. I didn't expect to like/want the headrests but it's perfectly comfortable and I'm glad to have it.
