The chair is on the firmer side and has decent lumbar support. I use it for an office chair and It is surprisingly comfortable compared to other's at a higher price point. It is only about a 3-4 hour a day chair if you have lower back issues and need longer use try the Serta chairs. Assembly of the chair was easy and straightforward and took about 30 minutes The top of the arm to the floor's lowest position is a little higher at 28.25" to 28.50". I'm 5'7" and 185.
This is a great chair for practicing music and recording. I love how the arms rotate back essential for playing stringed instruments. Comfortable and nicely adjustable. It's a winner!
This is a very nice computer chair. The ergonomics are just right for me. I usually supplement with a seat cushion but with this chair I don't have to. It went together pretty easily. The engineering is simple but solid. It's everything I need and none of the extra fancy stuff that would just get in my way. Even the hardware seems above average for an assemble-yourself item. FYI if you have a ratchet screwdriver that allows Allen tips (hex keys) it will make assembly go much quicker.
Great chair at a good price - very comfortable and very stable and was super easy to assemble. Definitely recommend this chair if you want a nice basic gaming or office chair.
