Wayfair

We bought an excellent outdoor sofa that can be turned into a bed. It’s awesome.

I recommend outdoor from West Elm/Pottery Barn/Williams Sonoma! Great quality and materials that don't off gas you. We did teak Adirondack's from Pottery Barn, timeless style in a forever material. FWIW my landscaper designer said 4 chairs, 2 side tables and 2 ottomans is the perfect design scheme.

Because you have a screened in porch (with a roof), your furniture will last much longer than something in the open air. Take care of them. Bring cushions inside in the winter and cover during heavy rains and pollen season. My cushions are at least 20 years old and I finally recovered last year for an update. The furniture structure is still in great condition.
