This is a sturdy, well made bed. I was hesitant to order a bunk bed online, but I am so pleased with my purchase! The blue is such a great color! It is almost impossible to find a 5 inch mattress for the top bunk, but we bought 8 inch mattresses that work great on the top and trundle. On the bottom bunk, we used a traditional twin mattress. I like that the ladder can be used on either side and that the beds can also be used unstacked if they get tired of sharing a room.
