This is a prototype of a custom designed chaise lounge. The frames are made of laminated mahogany. The seating surface is open-weave webbed material with grommets along the edges, through which is laced to the side rails. It was made to order by a company that supplies “trampolines” for catamarans, so it should be plenty strong, and it’s made for the outdoors. Very comfortable! Next one will have arms as well.
