Naturally, not the highest quality...but honestly for the price you pay, it is great. Does the job. I bought these for my guest room at my country place. It was easy peasy to assemble and does the job. The drawers are not on a bracket mechanism. It is literally a drawer in a box. You just pull it out and push it in. It is not adhered to anything. 
Also, I should mention, the bars are metal, not wood. The framework.
