In 1943, Ralph Rapson originally conceived his Rapson Outdoor Cave Chair as plywood with a cushion, inspired by his architectural design for the earth-excavated Cave House. Neither project was built. But today, that over-sized, futuristic, comfortable and fun chair is reimagined entirely in bright and durable recycled milk jugs and High-density Polyethylene (HDPE) - that's the Loll Designs Rapson Cave Chair.
