A pneumatic lab chair for labs, clinics, exam rooms and classrooms: a back that adjusts four ways, an 18 in. wide seat with 3 in. of foam, and a 300 lb capacity.
- Back adjusts four ways. Raise or lower the 16 in. wide back and move it forward or back to fit each user; pneumatic height adjustment sets the seat.
- Three height ranges. Desk Height 17–22 in., Medium Bench Height 20–27 in. or High Bench Height 24–33.5 in., measured from the floor to the top of the seat. A foot ring is optional at Medium Bench Height and required at High Bench Height. Seat Height Guide
