I purchased this for my father's wheelchair, but due to physical issues, he couldn't use the wheelchair, so it's unused, only opened. For someone who can use it. It will be shipped on Monday or Tuesday when I return to my parents' home. Please understand. [Product Description] The moderately firm, high-resilience material alleviates pressure on the buttocks. With a thickness of about 8cm, it's suitable for long periods of use. The cover can be removed with a zipper and washed if it gets dirty. The fabric is a soft, velour-like material. The back is non-slip to prevent the cushion from shifting. This lightweight cushion is designed to fit perfectly on the seats of self-propelled or assisted folding wheelchairs. "Size" Width 40cm x Depth 40cm x Height 8cm * Fits perfectly on standard wheelchair seats #Wheelchair #Elderly
