Hi, thanks for contacting Houzz. The Kinzie Dining Table is made of rustic pine. It is not all wood, as it would be more susceptible to warpage. Therefore, we add veneers, also pine. It has a top coat of lacquer. However, as with any wood furniture if you leave a glass on the table for a long period of time and it sweats it can cause water rings. I hope this is helpful to you!

Thank you!
