Meet the LEX seat: a folding exoskeleton that turns into a chair, allowing you to sit anywhere with the proper posture. It also takes the load of the backpack off your body. The LEX weighs only 1kg, so you can wear it everywhere.
The LEX is pretty simple to wear: simply 3 straps are needed to fit it on your body. It has an aerospace-grade aluminum construction and water resistant fabric. It can withstand up to 120kg of weight.
