A pneumatic wood chair on a round tube base with the foot ring built in, for labs, classrooms and work areas: a 7-ply hardwood seat and back, a back that adjusts four ways, and a 300 lb capacity.
- Back adjusts four ways. Raise or lower the 15.5 in. wide back and move it forward or back to fit each user; pneumatic height adjustment sets the seat.
- Two height ranges. Desk Height 17.75–23 in. with caps, 19.75–25 in. with casters; Medium Bench Height 20.5–28 in. with caps, 22.5–30 in. with casters, measured from the floor to the top of the seat. The foot ring is part of the round tube base. Seat Height Guide
- Solid hardwood seat and back. 7-ply furniture-grade hardwood with a natural finish: a 16.75 in. wide, 16 in. deep seat and a 15.5 in. wide, 10 in. high back.
- Feet for your floor. Caps: non-marring, no wheels, so the chair stays where it is placed. Or Self-Braking Casters: the chair resists rolling while empty, then rolls once you're seated. Caps and casters suit hard and carpeted floors.
- 15-Year Warranty · Lifetime Cylinder Guarantee. 15 years against defects in materials and workmanship, and a replacement gas cylinder at no charge for the life of the chair.
