For the price, this is a decent option. If you want something seriously sturdy youll need to spend twice as much buying something made of wood from an actual furniture store, but this one is ok as long as all the bolts are tight and its anchored well to the wall. I cut two lengths of 2x6 poplar and screwed them to the wall in order to anchor both top and bottom bunk using rigid electrical pipe brackets (ie the kind holding power line drop to a house). Plenty sturdy that way. Top bunk rail is perfect height for 8 inch mattress, you could even squeeze a 10 inch mattress up there if you want and still have some of the rail there to keep you from rolling out.
