â¹9,000 pillow uses NASA tech to prevent users from sweating
US-based company Simba has developed a pillow 'Simba Hybrid' which responds to users' body heat, thus preventing them from sweating. Priced at nearly â¹9,000, the pillow adjusts as users move, allowing trapped air to circulate so the surface stays cool. The pillow is covered by Outlast, a material which was originally developed for NASA to protect astronauts from temperature variations.
