Our THE·o·REM mesh office chair is available two different versions: base and premium.  The base version is feature packed boasting a cool mesh upholstered back featuring a ratchet back height adjustment, a soft sitting black upholstererd seat (3″ hi-resiliant foam), a bonus secondary lumbar adjustment to insure precise lumbar support, upright lockable synchronous-tilt (keeps feet planted throughout the tilt), pneumatic seat height adjustment, tension control adjustment, 8-way adjustable arm kit (height, width, depth, and articulate twisting), and a sleek commercial-grade black polymer spider base.  While keeping all the same features as the base office chair, the premium “All Mesh” office chair converts the padded seat to full mesh and upgrades the plastic base to stunning chrome.
