This seat cushion promotes proper posture to help alleviate back pain. The backrest has a wooden support covered in foam that gently repositions the spine and shoulders, encouraging optimal lumbar alignment while discouraging slouching, a major cause of back discomfort. An adjustable-height, removable lumbar pad relieves pressure on the lower back and encourages proper alignment of the spinal column, reducing strain on spinal discs, the shoulders, and neck. The molded wood and foam seat provides pelvic support, relieves point-of-contact pressure, and disperses your weight to alleviate pressure points. The seat cushion straps to any chair, car seat, or bench for stability and has an integrated handle for ease of portability. Polysuede cover. 19" H x 17" W x 16" D. (5 1/3 lbs.)
