Hello! I've reviewed the assembly instructions for the WF198242 Dining Table, and WF198243 and WF198244 Dining Benches. This document provides a detailed guide for assembling the table and benches, including parts lists, hardware lists, and step-by-step instructions with diagrams. I'm ready to answer your questions about the assembly process or any other details you might need.
What should be done to avoid scratching the parts during assembly?
