1" Upholstery Foam (size 1x24x108) is the right thickness, width and length for larger upholstery jobs that do not require a thick padding. The 9 foot length makes it possible to upholster a king or queen size headboard without having to cut the foam. It is also long enough and just the right width to be placed under sofa cushions for additional padding and comfort. If you are looking to add luxury to your home, upholstering the walls can help. This 9 foot length will cover most walls from the ceiling to the floor and the 1 inch foam adds just the right thickness.
