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!
