Very difficult to put together.  Accidentally put leg K on wrong side and impossible to remove screws now. Bolts have a built in rubber washer and according to a contractor if they broke while screwing in can only be cut off. Will try to just put up without tables but that was the feature I wanted. You absolutely need 2 people to put together. Had I known it was this difficult. I would have paid for assembly. Price was very high though for assembly. Extremely dissapointed!
