The wedge design of the Breyta seat cushion encourages correct pelvic positioning and spinal alignment, helping to reduce back discomfort. A discreet hidden coccyx cutout at the back of the cushion relieves pressure at the base of the spine. For convenience, this wedge seat cushion includes a built-in carry handle, making it easy to transport wherever you work. Made with sustainability in mind, the foam is composed of 93% pre-consumer recycled content, and the fabric cover is crafted from 100% post-consumer recycled polyester.
