Mostly MDF with Cedar trim I used this as a router table base but it can be easily modified for your purposes. Lots of storage capacity underneath. Top is 1 1/2 in thick and is reversible. Heavy and very stable. Size is 34 in long x 26 in wide x 26 in high. Would make a great jigsaw, drawing or Lego table. In the Luxton /Happy Valley Elementary area of Langford.
