I bought this for my 3 young sons, ages 3,5 and 7. This bed seems sturdy everywhere EXCEPT FOR THE WOOD SLATS SUPPORTING THE WEIGHT OF THE MATTRESS (and the child.)

We watched the very flimsy wood slats bend A LOT as my 7 year old gets on the top bunk. I don’t think we will be able to use this bed long because of how flimsy the bed slats are. 

I would NOT recommend this bed for bigger kids or kids that weigh more than 70-80lbs.
