The beach thingy instant beach chair is a chunk of plastic formed to the shape of a chair backing that you stab into the sand and can lean your back against it while you are sitting in the sand. Unfortunately for yourself the prongs can not penetrate far enough into the earth to hold the ungodly amount of body fat you stand to push against this piece of plastic, but assuming you are able to depart your mattress using your own strength, the instant sand chair will be a great addition to your beach going essentials. The beach thingy sand chair measures 15.25" x 25.25" and weighs 2.22lbs and can purchase one for the price listed or purchase 10 instant sand chairs for $125.
