I almost bought another bed because this said 5 to 6 week delivery. I received it in two days! I just assembled it myself, very easy but a bit long because I was so anxious to see it. But now I’m wondering how it will be with a memory foam mattress Mattress hasn’t arrived yet, but I’m very skeptical  that this will be solid for two people. It does say not to use a box spring — any comments out there
