Terrible terrible product, very complicated to assemble and poor instructions given. some of the shelves arrived with dents in them already! The back panels do not even fit to measure to assemble well, so could only fit some of them. The product/mdf material crumbled as the nails went through it. Please do not buy it. The worst purchase ever. Polluting the world with very cheap products that are completely useless. I am requesting my money back.
