History of the Portaledge

Research into the limits of contemporary furniture uncovered the Portaledge, the archetype designed and used by climbers to ascend previously unclimbable walls. To find out how this superb example of survival design was conceived and developed, interviews were conducted with the original designers Conrad Anker, Mike Graham and John Middendorf, and the first comprehensive history of the portaledge was gathered and published in this article.
