This wheelchair-specific cushion was created with that desire in mind. 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 a wheelchair cushion】 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 treatment on the bottom prevents falls from the wheelchair. 【Easy to attach and detach 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 detach the cover and to insert and remove the inner cushion.
