I have a Casper Twin mattress and bed frame that are about five years old. I don't believe they sell this exact model anymore, but it was the most basic one at the time. It is solid foam, no springs. The frame is dark gray and sits on the floor. Comes with slats that the mattress rests on. Please come with assistance to move the mattress and frame down two interior flights of stairs and a short outdoor flights of stairs. The dimensions listed are for the mattress. The frame is 7.5 inches high
