Blue vinyl fabric mid-back petite stool with arms, grade 3. All BodyBilt Small-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 slightly contoured seat on this model is one of our most popular designs. 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. The J style mechanism rocks from a center-pivot point under the seat, and allows for the backrest depth adjustment feature. The J756 chair is a popular part of BodyBilt's Mid-Back Task seating line and offers a comfortable choice for the smaller worker who desires a minimal amount of contour. This chair was designed specifically for desktop intensive job performers. The J756 features ten ergonomic adjustments that allow the user control their own comfort level.
