(40 x 40cm) 1 valve The hybrid type combines "the comfort of air alone" + "the support and durability of urethane," enabling more practical and stable seating support. Thank you for viewing. There are no air leaks, but as this is a used item, the cover shows signs of wear such as scratches and stains, so please check the images. There are no accessories. Everything in the images is included. I will be listing this item until July 21st due to work commitments.
