I've had this bunk bed for my nephew (age 4) for about 6 months! I love me bed and trust that it won't fall apart on me. I had a bit of a hard time assembling the bed because it need extra force that I would usually provide with a hammer. I DO NOT advise using a hammer while building. It will crack remove the paint; maybe if you wrapped a shirt around it and turned it sideways and you were VERY CAREFUL. other wise he loves his bed and it always has his back. 

The bed is great except it's slightly dangerous for young kids. My nephew is regularly slipping on the ladder. It could use some textured strips for traction. Also the bars are short for traditional mattresses. He has not fallen but it makes me nervous. 

Pros: Durable. 
Cons: Slippery
