The Alvin Paragon Mesh Back Office Chair CH760 is a sleek ergonomic chair that moves with your body when you wish to lean back and contemplate a job well done. The back and seat feature a synchronized rocking motion with adjustable tension control-- for every 2° the backrest moves, the seat automatically moves 1°. If you want the seat to stay upright, it's easy to lock it in position. You can rest your arms comfortably on the height and width adjustable padded armrests with 7 available positions. The breathable mesh back is depth adjustable, too.
You can set the seat height of this adjustable chair from 18" to 23" with the pneumatic control lever. The black fabric upholstered seat is made out of molded foam measuring 20"L x 18"W x 3½"H. The backrest measures 20"W x 21"H. You can move your chair around the room on its 5 swiveling wheels, while the 26" diameter reinforced nylon 5-arm base gives you support and stability.
