Jaguar Land Rover is developing what they deem to be the car seat of the future—a pioneering shape-shifting system that’s designed to improve comfort and reduce the health risks of sitting down for too long.

The ‘morphable’ seat, being trialed by Jaguar Land Rover uses a series of actuators in the seat foam to create constant micro-adjustments that make your brain think you’re walking, and could be individually tailored to each driver and passenger.

If this sounds familiar, it’s because Mazda currently uses this technology on their new-generation vehicle. Though their design doesn’t contain any electric actuators, Mazda optimized its seat design to maintain the spine’s natural S-curved shape—its shape while walking or standing upright.

Anyway, going back to Jaguar Land Rover’s research, they find that by simulating the rhythm of walking, the tech can mitigate against the health risks of sitting down for too long on extended journeys.

More than a quarter of people worldwide—1.4 billion—are living increasingly sedentary lifestyles, which can shorten muscles in the legs, hips and gluteals causing back pain. The weakened muscles also mean you are more likely to injure yourself from falls or strains.
