The Lexus UX Concept CUV introduced at the Paris auto show last year is noteworthy for several reasons: It features an unusual bare-bones “deconstructed” interior design; a separate world premier was staged at the motor show just for a more refined version of the vehicle’s seats; and the seat material is made from spider webs.
Auto designers have been dreaming up lightweight seats made of gossamer wings for decades, but the Lexus Kinetic Seat Concept uses synthetic spider silk that is a functional and extremely tough material.
Made by Japan-based Spiber, the main ingredient is protein created through microbial fermentation. The protein then is spun and processed into a new material with impressive properties. Another benefit is it is not derived from petroleum. Called QMONOS, it currently is being commercialized for a variety of applications.
What’s more, the seat isn’t just a gimmicky sling or a hammock. The seat cushion and backrest are designed to move kinetically with occupant weight and external forces. Sitting in the seat helps stabilize head movement caused by vehicle motion, keeping the field of vision steady, Lexus says. It’s unlikely this idea will show up in production soon, but it illustrates how hard automakers are looking for new ways to impress consumers with style and comfort while chopping weight at the same time.
