Cheap wood, pine. Came in slightly warped. Finally put it together and used light soil. By next day, leg had split away and we could not get it to fit again. Warping had gotten worse!
Chose cuz it was cheapest but you get what you pay for. Cheap soft wood, and pro fitting for floor boards had me swearing at this thing 20 mins in. Save your aggregation and buy a better fitting product elsewhere.
The first raised garden was perfect but the second most recent one we got had lost many of the letter stickers to help put it together which made it challenging! Just happy we had the first to use as a model!
