Using 'indoor' furniture on porch
What would I need to consider in order to use non-outdoor furniture on my 20 x 17 screen porch? Budget's getting tight and I was thinking that I could maybe use our old breakfast table (wood top, iron base) out there. But even more intriguing was my husband's idea to get a futon off of craigslist to use as the porch couch. I guess I could recover the mattress with an outdoor fabric but wouldn't it still get moldy? I see people on tv and on the internet all the time use a daybed or something similar so what do they do to prevent mold? DH said if he got yucky we would just throw it out and get another almost free one off of craigslist. We will have 30 inch overhangs so I doubt rain could directly hit any of the furniture, but the damp air is sure to get it. We live in the mountains of NC.
