Getting old sucks. My doctor wants me on a very firm (not quite the floor) mattress for my back (a bit of arthritis in the lower back). I've got one of those high-end air mattresses - the Select Comfort. I posted a note on the neighborhood board - free - so far no takers. Is this normal? It's not the conventional mattress which by law, must be tossed. The cover can easily be washed (well, it takes the big washer at the laundromat) and the rest of it is the frame. Any ideas or do I just toss the air mattress in the garbage and the frame in recycling?
