Initially Horan and Gardner designed the bench with aluminium rings for the feet, but switched to timber because of its much lower environmental footprint. The surface of the bench will be durable, as will the feet. If the plywood for the legs requires more frequent replacement, it will be compensated for by the fact that it is so light in weight. Overall, this is a solid solution created with great economy of materials, and can pack away to a minimal volume for transport.
