This lazy inflatable sofa is made of polyester fabric. It can be used not only on the smooth ground but also on rougher surfaces such as those with (small) rocks, or hard pavement. It is fast to inflate and deflate, filling up with air similar to the wind catcher. It can weight up to 400 pounds. It is also great for those long hiking trips, hanging out at the beach or the park, sunbathing in your backyard or at your favorite outdoor festival. Besides, it is easy to be packed into a compact bag when not in use.Customized imprint and color are available.
