I purchased two of these for my kids.  They love them!  They love having a "sleep over" in each others rooms! 
The only con is that it's a little hard to pull out and push in the trundle but that is expected so no big deal!


Pros: We were able to use the box spring and the kids love how high up the beds are!
Cons: It's a little hard to pull out and push in the trundle but that is expected so no big deal!
