I purchased this item used and have only used it once. (There is some wear on the surface, but after sleeping on it at home for one night, it was still firm the next morning with no air leaks at all.) The previous owner also said they had used it only a few times and inflated it with an air pump. *I have listed the price based on the current selling price on Amazon. I bought this for solo backpacking trips as it packs down small, but I'm currently busy raising children and won't have a chance to use it for a while, so I'm selling it. It's about 8-10 cm thick. I think it's good for camping and car camping. - Brand: SEA TO SUMMIT - Material: Polyurethane foam - Color: Olive Green - Storage size: Compact storage possible Thank you for looking. *Simple packaging (cardboard box)
