This twin is a great substitute for a chunky bookshelf that easily holds as many books and objects. The shelves are slightly larger than I had imagined --I can fit my printer on the bottom shelf! The description specifies that each shelf will hold no more than 30 pounds, but from assembling it, I got the feeling that it would be a little sturdier than that. Because of its ladder design, I feel safe using it without having to install tip-over resistance. The sides are made in metal, but are hardly distinguishable from a distance.   

Pros: Easy assembly, simple design, large shelves, tip-over proof
Cons: Surface veneer chips easily
