This wheelchair-specific cushion was born from that desire. Under the supervision of a physical therapist, we worked with experts to consider the necessary functions, suitable materials, and shapes for wheelchair cushions. We offer it at a reasonable price so that as many people as possible can use it. [Three essential functions for wheelchair cushions] ① High-density molded urethane material absorbs impact on the buttocks and distributes pressure. Relieves buttock pain. ② The perfect size and 3D molding for wheelchairs firmly support the pelvis. Maintains correct posture and reduces the risk of pressure sores and spinal deformities such as kyphosis. ③ Non-slip processing on the bottom prevents falls from the wheelchair. [Easy to attach and remove the cover with a large zipper] The cover is removable and washable. In addition, the cover uses a large zipper with a wide opening. We have taken care to make it easy to attach and remove the cover and to take the inner cushion in and out.
