These mattresses are terrible! We purchased five twin and one full for bunk beds we have. I made sure I matched the size of the mattresses up to the specifications of the bunk beds and they do not fit into the frame. These beds are hard like sleeping on a board. Stuck with six mattresses now we will not use! Waste of money.  Very disappointed in the quality of these. I don’t even want to give this one star but it wont let me submit with 0.
