Neutral Posture AbChair

item#: NPC322

The Neutral Posture AbChair is a unique ergonomic chair designed to provide support for workers who find themselves in a forward-leaning position for long periods of time. The distinctive cylindrical cushion offers much-needed support when performing tasks such as medical or laboratory work and pivots a full 90° to provide back support when used as a traditional chair. This additional range of movement allows Neutral Posture AbChairs to provide dynamic support, helping to encourage the use of multiple sitting postures and reducing stress when seated for long periods of time.

Professor Ergo's Thoughts:

While we generally recommend sitting in a chair with a slight back recline to relax the back muscles and support the spine, some occupations require a forward-leaning posture for efficient work. The Neutral Posture AbChair offers support for both forward-leaning and standard sitting postures, thanks to a rotating cushion that can be placed in front of the body for support in medical, industrial or scientific applications, and can be rotated back to act as a back support when needed. Additionally, multiple seat cushion styles and upholstery options are available, allowing the AbChair be used in the office, clinic or cleanroom.
