I'd love the stairs to make a bridge over the pool. The split would allow exit over the pool or under near the house. Under Deck Design Ideas, Only missing is underdecking to protect under deck patio from rain. Love the swing.
buy the wood from home depot, use the screws to hook the chains with and make it the size of a twin size bed.buy an old twin size mattress cover it in plastic then in outdoor fabric to make a cool swing for the covered patio @ DIY Home Design
