Designed by Mexican architect and designer Ricardo Garza Marcos, this curved elastic bench, presented at Designweek Mexico, uses vertical cuts in the wood to give the stool some elasticity.
But not all woods are suitable for this bench design, and the designers tested different types of wood, as well as the depth and spacing of each cut.
Test results used a type of Mexican cypress called ahuehuete because it provides the required strength and flexibility.
The bench seat is made from a 3-inch-thick piece of wood with 87 perfectly spaced cutouts and two grooves in the steel frame.
Once a person gains weight, the seat begins to flex for a soft, cushioned feel. The point is that there are no auxiliary materials, but the comfort given by the whole piece of wood.
