A healthy posture and office master's dependability is a combination that will benefit everyone. The discovery back series come with "molded memory foam backs" standard, which is extremely supportive and comfortable. Healthy posture is achieved across entire line with extensive standard features. Affordable selection of enhanced ergonomic seating.

Sigh-Producing Comfort: DCS Technology creates a seating experience that is at once soft, supportive and beyond compare.



Options 6: Lumbar Selection

The height and shape of the lumbar support should coincide with the lumbar curve ("the small") of the user's back. The support should be firm, but not cause localized pressure points.

The adjustable lumbar option on Office Master Chairs is a knob that changes the firmness of the lumbar support. Also most Office Master Chairs have adjustable height backs, allowing users to find the correct lumbar support position for them.
