Selling my used full/queen (it's bigger than full but smaller than queen) memory foam mattress with a custom made frame that fits right over a disassembled Stanford bed so you don't have to worry about storing it.

You can see the outer frame in the picture attached.
Then a series of 2x4s (included) are attached to set the bed on.

I'd keep the bed but the new place I moved into already has one.

Catch: you have to pick it up, or I could help you for another $20.
