I want a sturdy, durable bed that is inexpensive for my new place. I was excited about foldaway beds, but it seems like they are not durable. Any suggestions on a bed that's cheap but durable and comfy? I did look into sofa beds, but I was unsure if they would provide my back with the support it needs, and a foldaway bed would be easy to move. What have your experiences with non-traditional beds been? #finance source
