I bought one for about 250 or so last year and its still going strong. Its VERY comfortable and helps my back in the morning. I would definitely recommend it.
So if you go from a spring mattress to memory foam, can you put your memory foam on top of your old box spring? I've heard you don't need a box spring for memory foam, but if I buy the memory foam, I'd like to keep the same frame/box spring if I could.
I kept the same box spring and frame...it works fine for me. There are other frames that provide more clearance under the bed for storage as well.
