If you thought the recently unveiled Lexus UXconceptwas outlandish, wait until you check out Lexus' other Paris auto show debut. Called the Kinetic Seat Concept, this wild throne is a spindly take on what we might see in cars of the future.

However, this seat isn't all show. In an attempt to provide ease of movement and relieve kinetic forces from the driver's back, both the seat and the backrest move and flow with the movement of the car. According to Lexus, this is the best way to remove stress from the driver's body and spine.

See that spiderweb design pattern? That's no accident. The material in the backrest is synthetic spider silk. Despite being petroleum-based, this "silk" contains a large amount of protein formed from a process Lexus calls "microbial fermentation." Lexus chose this material for its strength, flexibility, and shock-absorbing properties.

Thanks in part to its airy construction, any car equipped with these wild buckets would benefit from a good amount of weight reduction.

We can't imagine we will see anything like this in regular production anytime soon, but the synthetic spider silk could have potential applications beyond sci-fi car seats.
