On a day at the beach, it's nice to have a chair along, but most beach chairs are a hassle- they're clunky and involve a lot more metal and material than is necessary. So it's nice to see this design, the "Sand Chair," by Tovdesign. It's super simple, made of only a towel, a rag, and four broomsticks.
It's not an especially supportive chair; in fact, your butt will likely be on the sand. But it's enough to prop your back up; I find that much more comfortable for reading on the beach.
Apart from its simplicity and minimalism, the Sand Chair takes up no more room than your towel- which you can still use to dry off. I heartily approve.
