This canopy bed was both fun and different. I had to figure out the top. Not heavy but sturdy. the post are 1 inch oak and the top is made from 1 inch square stuff. It is glued with Titebond glue and also has a 2 inch screw in the end of each slat. the bottom is 1/4 inch oak plywood. also made 20 inches long for a 18 inch doll. My wife makes all the Bedding you see on all these Beds.
