We've been living with this trundle bed for more than 7 months. What a disappointment. It took hours to assemble and the trundle beneath doesn't take a standard mattress, so it's always getting stuck. Incredibly frustrating. Don't buy this item. Too hard to return and it's not efficient with the constant pushing and pulling on the trundle.  

Cons: Heavy. Cumbersome. Trundle doesn't slide out easily at all. Really annoying.
