Product Description Excellent stability when sitting. This popular cushion is ideal for preventing bedsores (pressure ulcers). It is also recommended for those who already have bedsores. Selling due to replacement. There is a repair mark at the location indicated by the red circle (see photos for details). *Please refrain from purchasing if you are concerned, as this is a used item. I have a dog, so some hair may be attached to the sticker on the back of the cushion. Please remove the sticker if you are concerned. Before listing, I soaked it in water in the bathtub to check for air leaks, but please consider the possibility of a leak somewhere just in case. I did not find any air leaks from the valve.
