Purchased a few years ago at Alpen Outdoor. Selling due to a change in camping style. Used about 10 times. The photos show the item before inflation (actual item) and official photos (from the 7th photo). There are a few stains, so I'm selling it at a lower price. When rolled up for storage, the sponge inside has some creases and doesn't roll up evenly. However, as shown in the photos, there's no problem storing it in the storage bag. Simple cleaning and alcohol disinfection have been done. *Please refrain from purchasing if you are a nervous person or if you are looking for a perfect item, as this is a used item.
