For the price, this is an excellent bed.  I feel very safe letting my four year old use it.  My 6' 2" 21 year old brother stayed with us over Christmas break and there was plenty of room for him to sleep on the bottom bunk.  It feels pretty sturdy and the ladder is at a good angle.  The drawers are great for him to store his trains and cars in.  I wouldn't put things that are very heavy though.  Overall I am very happy with this purchase.
