Tinwell Rounded Picnic Bench Description This novel twist on a classic design is a good looking and long lasting addition to any garden. Tinwell Rounded Picnic Bench Features Like all of our wooden furniture, the bench is constructed using heavy duty joinery grade redwood timber, sourced from responsibly managed forests, so as well as lasting for years you can be sure that it is environmentally sound too. We also use corrosion treated heavy duty fixings and protective black plastic screw tops throughout so that the components remain securely fastened year after year.
