I assembled the chair last night. First day using it for working from home and my tailbone has been numb all day. Terrible lower back posture as well. Do not buy.
I'm a short guy and this is perfect for me. Out of many office chairs I had this has the best back cushion; super comfy and good support when I sit on for work. The arms support may be not great for tall people as it's around my belly.
So comfortable. Just the right amount of cushion in the seat. Good lumbar support. And super nice glide to the wheels. Great purchase for the price. As a matter of fact I ordered a second one for my hubby.
