Who says you can stretch out only on a chaise? This antique Spanish-cedar bed frame can weather the elements just fine, but even one made of inexpensive unfinished pine can be protected—and warmed up—with the right finish. Then, for a mildew-proof mattress, zip a custom-cut foam slab into a waterproof vinyl cover and add a fitted-sheet–style topper stitched from quick-dry weather-resistant fabric. Finish with outdoor cushions, as well as indoor linens—if you're willing to bring them inside in damp weather.
