SOMEONE GOOFED BIG TIME! The drawers will not go into the cabinet. There is 1/4 inch gap under the bottom of drawer and cabinet which elevates the drawer,  preventing it from closing all the way. And the drawers do not slide easily. We attempted to move the brackets down with no luck. AND we used a level as we assembled the cabinet.
The drawers cannot be used as they are intended.  Have been living with it since assembly but the force needed to close the drawers is very hard for me at 91 years old. There is a terrible odor from the wood and irritated my nose and throat, it is somewhat better since it has "gassed off". I had decided to live with the cabinet, but I am finding the drawers to be a very hard thing to deal with. I will be calling customer service.
