looks to me like press-board. There is metal bracing under the edges. The top surface is good, smooth. It all seems quite sturdy. Have enjoyed playing on it so far, no issues. Have not tried to fold it up yet, but that looks to be pretty straight forward.
The shipping weight of the table is 200 pounds. The table will weigh around 5-10 pounds less than that due to packing material adding extra weight. Please reach out to email@example.com with anymore questions. Thank you
