While not traditionally the kind of mattress most people buy or use, this air mattress serves two purposes — first, as an outdoor or camping mattress, and second as a boat to use in the river. Pretty clever, huh?
Designed by Japanese fellows Ivan Zhang & Jeho Yoon, this piece goes from being a mattress to a boat by properly hooking up the rope system that is found inside the mattress. There are seventeen points to these all in all, with the ropes carefully laid out. The rope can be controlled to switch to its different forms. And because it is purposely made to be transparent, it would be easy to see how this is done successfully.
