Chair is perfect for me. I'm 5'9 170 lbs 62 years old. Mesh seat and back are very comfortable and cool which is especially important to me living in hot dry desert climate. Arm supports are adjustable to my satisfaction and fixed lower back support fits me well. Chair looks light but is as heavy as a leather chair of similar size. A more adjustable chair with better ergonomics would cost MUCH more. This one suits my size and budget fine.
I was a little wary about a full mesh chair because I am used to ones with cushions but so far it is great. You dont have the same pressure pushing against your joints and it feels fantastic and neck support is just right.
shame on staples to have a product poorly enough designed that the mechanism squeaks. re arms: I like to sneak my knees under my desk. the forward facing arms prevented that. So they are now rearward facing.
I've been looking for a chair that would support my back and neck. This is it! Most chairs don't support your neck and head at all or not very well. I sat in every chair on display and none of them had the neck support I needed except this one. And you can lean back in the chair and be comfortable enough to take a nap - okay at home not so good at work.... The lumbar support fits well and is adjustable. When I sit in this chair I want to sit up. I have a much more expensive chair at work but I have a tendency to slide down. Not with the Hyken chair! Note: This chair really forces you to sit up straight.
