I asked to return it. After assembly I tryy it Ed to secure the bottom shelf supports. The screws would not penetrate the wood or broke. I them tried to add the rollers to each leg. Thh by e screws only went in a 1/8 inch and I had to use my drill. I was gentle but hand the screws broke off  I sued the leg and the other screws even with the drill bit gently turning stopped a quarter inch from the bottom of  each leg so the  rollers slide around which is dangerous.
