A big problem where a dowel was already installed on one of the sides and was forced in where it shouldn't have been and split the wood and veneer. It hopefully won't be seen because it will be on the inside of the cubbies under the bench. Now we are having problems attaching one of the sides of the bench because the bolts were installed securely. So far I'm not very impressed with the quality of the furniture that has to be built after delivery. Maybe Wayfair should consider having their pieces manufactured somewhere else where they can guarantee better quality control.
