Skateboard rails

The stacking rails on the Aluminum Chair were inspired by these 1980s skateboard rails, which are made from milled nylon, and were designed to be screwed to the underside of a skateboard to protect the graphic under the board and allow the board to slide smoothly on curbs, railings, and ramp coping. Adapting these rails for the chair allow the chair's profile to remain slim, and protect a great surface area of the chair's seat from scratching as chairs are stacked. Protruding 3mm from the chair's side the rails also protect the sides of the sides of the chair.
