Calling this a "chair" is perhaps doing it a disservice. MWE Labs describes it as a "work environment," and even that doesn't really capture what's going on here.
Anti-glare lighting, total sound and imagery immersion, completely adjustable (and heated!) seating in multiple dimensions... this thing is nuts!
The price tag matches the insanity of what's on display, starting at a mere $5,300 with none of the extra bells and whistles and going way, way, way up from there as you add on more features.
