This is a terrific bed with an easily accessible storage chamber underneath. I was in desperate need of a very large space to store my paintings on paper which need to lie flat. This was a great solution in a small guest bedroom. The hydraulic lift makes it easy to lift the mattress up and the compartment is as wide and nearly as deep as the king mattress. The only challenge is, you cannot lift it easily when all the pillows or heavy bedding are on. So I undress the bed a bit to lift it. Small price to pay for such a great storage solution.
