Blue fabric high back task ergonomic chair with arms, grade 3 comfortek. All BodyBilt High-Task-Back chairs provide exceptional comfort with upper and low back support. 10-Point Posture Control adjustability puts at your command the tools to address and alleviate stressful aches and pains so often escalated by inferior chairs. The moderately contoured seat on this model is our most popular design. With passive weight distribution via surface contact this model encourages proper-seated posture and cushions the high-pressure points that lead to discomfort on flat seat designs.
