This loft bed is very stable and we did not feel there was a need to attach it to the wall. We are very very happy with the price, the product, the stability and the workmanship. The only reason I did not give it 5 stars is due to the fact that there is no section without railing to allow the child to climb in and out easily, without having to get a leg over the top of the railing. It is easy to do with my 11 year old granddaughter bet puts her in an awkward position to lift her leg over and then stretch down far enough to reach the first rung of the ladder. It appears it would still be stable if the top one or two bars were removed in manufacturing that would allow easier step down.
