Ever since I snuck up to the rooftop pool at W Hotel in New Orleans for a late-night swim, I've been convinced that a cabana is the key to the ultimate poolside haven. Not only can you use it to slip into your teeny weeny yellow polka-dot bikini, but it's also a great escape from the sun and other poolside dwellers. In other words, it's the quintessence of Summer style. Those of you with a pool might want to open your ears now: the Pottery Barn Chesapeake Changing Cabana ($299, reduced from $429) is on sale and ready to make its debut in your backyard. And, it has a FSC-certified solid eucalyptus frame finished with a protective oil-based wood stain, so it may actually outlast your bikini years.
