Theres never been a duvet quite like the TEMPUR-FIT quilt. Its designed to reduce overheating by creating a perfect personal climate for each sleeper, so you stay cool when the weathers warm, and warm when the weathers cool. Its all thanks to the unique NASA-inspired TEMPRAKON filling. Light and soft, its climate-regulating properties help maintain your ideal body temperature and reduce perspiration. Even better, it adjusts independently to your sleeping partners needs, so both of you enjoy deeper, more restful sleep. Along with TEMPRAKON, the TEMPUR-FIT quilt is insulated with beautiful European down feathers for even greater softness, and is encased in a cover made of 100% cambric cotton. The cover features the TEMPUR anti-microbial FRESH treatment, making this duvet a perfect choice for anyone with allergies, too. Beautifully soft and superbly comfortable, the machine washable TEMPUR-FIT quilt is available in single, double, king and super king sizes.
