Our boys love these bunk beds! They are 5 and 3 and loved them right from day 1. 
They are very happy to have the drawers built into the stairs and the shelves along the side of the stair case. 

The bottom bunk is great because it is high enough off the floor to add storage bins if you need extra space. 

I would have given 5 stars but a couple of the pieces were damaged when I unboxed it all. Pretty disappointing when you buy something brand new... especially since they were a Christmas surprise so we couldn't take the time to contact wayfair and have replacements shipped.
