A group of engineers has created this exoskeleton that allows elderly users to enjoy activities like fishing, commuting and golfing for extended periods.

Created by Astride Bionix, the Lex is a wearable chair comprising a black seat fixed onto the body with straps that tighten around the hip and just under the buttock.

Two metallic legs swing underneath to rest at an angle that forms a 120-degrees "body-thigh sitting posture", which Astride Bionix says is best for body health.

The team behind the project – a group of wearable-robot engineers – created Lex as a quick and easy aid for older people in everyday activities.

"We decided on making a wearable product that doesn't require an electrical motor and has a clear function so it's easier and faster to develop," Astride Bionix's Don Plooksawasdi told Dezeen.

"The problem we are trying to solve is that there is a growing number of people in the world who are ageing and they find it difficult to do activities like fishing or golfing or commuting for an extended period of time," Plooksawasdi said.

"Giving them the Lex allows them to take a little rest so that they can go extra miles."

When not in use, Lex becomes a discrete part of the wearer's outfit; the legs fold upwards, while the upper strap acts as a support to alleviate the weight of backpacks.
