Overview & features

A tidy, supportive desk chair for home offices and small spaces. A large, padded lumbar support and an S-shaped mesh back cradle your spine, the waterfall-edge seat keeps your legs comfortable, and the arms flip up 90° so the chair slides right under the desk.

Why you'll love it

Big lumbar support: a large, thick lumbar cushion adjusts about 2" in height to cradle your lower back.
Seat that is easy on your legs: a 3.2" thick foam cushion with a waterfall front edge helps circulation.
Space-saving arms: soft-padded arms flip up 90° so you can roll the chair under the desk.
Quiet and floor-friendly: rubber casters glide without scratching hard floors.
Adjust and recline: seat height adjusts about 3.74" and the back reclines with a pull of the lever.
