I only know about the cabinets in the Reflection line. They are a little bit of both. The cabinet doors are stained wood. But the stiles and rails are covered in paper. For this price point, I don't believe you'll find fully wood built cabinets.
I am having a problem with mine. The paper on the stiles are getting some wrinkles in them. I've posted about it on this forum, and as far as I know, I'm the only one with a problem. I've discussed the matter with GD management and they have been very helpful. When we get back from our trip, they are going to send me all the materials and instructions on how to repair them. Then, I'll either do the work myself or take it to the dealer. That's the thing about GD products. If you do have a problem, they go out of their way to take care of you. Try getting that from another manufacturer.
