You must admit, after a couple of hours at the beach laying on a blanket or squirming on one of those webbed or canvas tinny beach chairs, your back starts telling you to head home. But not too long ago I came across a terrific alternative. It's named the Orthoseat. For both poolside and beach use, the Orthoseat portable beach seat is medically endorsed and recommended by chiropractors! Prayers answered! It"s terrific!
