first off i wanted this in grey. It seems that it doesn't exist anymore in grey. So i searched and searched and nothing else out there was what i was looking for. So i wanted this and tan it must be. so finding what size mattress that the trundle could fit was a nightmare! No one could answer me! there is no specs on what size mattress you need. So take this advise. 8 inch for the trundle works fine and you CAN fit a 10 inch in there. I suggest a 10 inch on top, i got an 8 and you can still see a crack of the wall between the back board and the bottom of the bed, so if you had an 10 inch on top then that would cover it. other wise seems pretty good. Make sure you have a power drill to put it together! and the bed slats that the mattress sits on are pretty janky, they could break i see in the future if someone sits on bed and slams down on it. But you can replace the slats i saw some at IKEA today.

Pros: looks good
Cons: putting it together, needs 10 inch mattress on top!
