I had no trouble putting them together and they seem sturdy to me. I do love the curved lines which is why I chose these. Agree with other reviews that the flat paint on the drawer front and cabinet door is pretty shoddy looking, and there were gaps in the finish at the seams of the side panels on both units. However, I touched all that up with dark paint and they are kind of in a corner where the finish isn’t very noticeable anyway, so I’m not worried about it.
