Love the chair, perfect fit for my size of body, mesh back gives full support to your back and lumbar while keeps you cool and dry. A large, cushioned seat relieves fatigue from long periods of sitting. Best of all, the 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° smoot. I can adjust the tilted angle of the backrest to enjoy rocking back and forth.
