Power through long work sessions in this ergonomic computer desk chair whose S-shaped backrest aligns with the spine and supports the lumbar curve. A breathable mesh back cools the spine, while the padded sponge cushion eases pressure points during marathon focus blocks. Flip-up arms swing 90 degrees so the chair tucks beneath compact desks, and adjustable height from 18 to 21 in pairs with a 90 to 110 degree rocking back and 360-degree swivel for tailored posture.
