This bunk bed is an incredible value and I would highly recommend It for anyone in the market for a low bunk bed.  It is extremely sturdy.  I bought it for my 7 year old who is afraid of heights.  I didnt expect her to sleep on the top bunk but because it is a low bunk bed, she immediately began sleeping up top, no problem.   Instead of a mattress on the bottom bunk. She just uses the space as a fort/play area.   It is also very stylish with three great colors to choose from.
