Lex

LEX is a passive wearable “bionic chair” (chairless-chair style) from Astride Bionix, designed to provide deployable sitting support and posture-oriented seating for daily life and commuting. The device is designed to fold discreetly while walking, deploy into an ergonomic sitting posture in about 5 seconds, and includes a load-transfer feature intended to reduce backpack load on the shoulders.

Description

LEX is a wearable seating-support exoskeleton worn at the waist and thighs and deployed when the user needs to rest. Astride positions it as a posture- and comfort-focused system for scenarios such as long commutes, standing fatigue, and waiting in queues. The system is described as lightweight enough to wear “at all times,” with a folding mode intended to minimize profile when walking and a three-strap donning method.

When deployed, LEX is described as forming an upright, ergonomic sitting posture with feet planted on the ground and thighs angled forward, intended to support easier breathing and reduce pressure on the body compared with a traditional 90° seated posture. The device is meant to support up to 120 kg (264 lb) and weigh slightly more than 1 kg (2.2 lb). A second core feature is a backpack load-transfer module intended to shift 50% of backpack weight from the shoulders to the “core” via a flexible panel and strap interface, and it can be used while standing or while seated. The Kickstarter copy also notes roll-up storage, a hook for hanging, multiple sizes, and four color options.

We know that chairless chairs like this are not a new technology, thanks to Ray Hu at Core77.com, who has a phenomenal article on the 40-year history of chairless chairs: “Who Knew?” The Wearable Chair Was Actually Invented 37 Years Ago.
