The s-shaped mesh back gives full support to your back and lumbar while keeping you cool and dry. A large, cushioned seat relieves fatigue from prolonged sitting. Best of all, our desk chair is highly adaptable to your preferences. The seat and lumbar support can be adjusted within a certain range of heights to accommodate different body types. Armrests are a great place to rest your arms and can be flipped up to save a lot of floor space. The star base with five nylon castors allows 360° smooth and mute mobility. To add more fun, users can adjust the tilted angle of the backrest to enjoy rocking back and forth.
