Solid construction, was easy to put together with the help of my 10 year old just to balance things.  Arrived with a few minor damages, but I attribute that to the shipping guys. Just used some wood glue and a clamp and it was an easy fix.   My son absolutely loves it and the fact that there is a hiding spot underneath is a bonus to him!!  
So sturdy that when he jumps on the mattress, the bed doesn't give at all!

Pros: Solid, storage, trundle, hiding area for the little ones to play underneath
Cons: arrived with a few surface damages
