Our ergonomic desk chair is designed to provide exceptional support for the hard worker in the office or at home. The low backrest, comfy armrests and Y-shaped support are all dedicated to relieving body pressure and pain. In addition, the breathable mesh back and seat keep good air circulation and bring a cool sitting experience. Height can be easily controlled from 16" to 21" via an adjustment lever located under the seat. Its 360-degree rolling base makes moving from room to room quieter and smoother. This office chair also comes with sit-brake casters to automatically lock when the load exceeds 66 lbs. It is a perfect choice that combines ergonomic design with a modern look!
