At first glance Archelis does not look like a chair at all. The wearable chair looks more like a leg brace. The wearer of Archelis will not get full comfort of sitting on a chair but the gadget actually wraps around the wearer’s buttocks and legs, providing support that effectively allows them to sit down wherever and whenever needed.
