Quick answer: This Drive Medical 16" back cushion adds targeted lumbar support and comfort to a standard wheelchair. It uses two layers of foam — a standard-foam base with a high-quality memory-foam lumbar section — that conforms to the curve of your lower back to improve seating posture. A durable Masonite stabilization board prevents hammocking in sling-back wheelchairs, a sealed liner protects the foam from moisture, and a non-slip vinyl back keeps the cushion from sliding. Fits most standard 16" wheelchairs; 300 lb weight capacity. Model 14906.
What is this cushion for?
For anyone who spends extended time in a wheelchair, a sling back can sag and offer little lower-back support. This cushion conforms to provide support to the lumbar region and improves seating posture while providing back support and comfort; it has two layers of foam — a standard-foam base and a high-quality memory-foam lumbar section — and a stabilization board secured on the back of the foam core that prevents hammocking in sling-back wheelchairs. A sealed liner protects the foam core from moisture, and a non-slip vinyl back prevents the cushion from sliding.
