My husband and I were very impressed with SOLID wood used in this bed.  Very sturdy design.  Metal support runs center length of bunks to aid support of mattresses and metal pegs hold the beds together. Design allows this bunk set to be used as two separate beds. The paint job is great, the joints are solid. Bed went together easily.  The ladder is very impressive. We were very impressed!! This unit exceeded our expectations!  Delivery was very quick, too! We are delighted! Highly recommend !
