View all mattresses in the Heritage collection. QUILTING LAYER: Shifman premium mattresses feature the exclusive Sanotuft® technique, which produces a smooth buttonless tuft that is hand-sewn from top to bottom, locking all upholstery layers securely in place. This process prevents shifting and bunching, extending the comfort life of your mattress.   Materials: Belgian damask, 2" sculpted super-soft high-performance foam, two layers of plush New Zealand woold COMFORT LAYER: This mattress blends artisanal luxe cotton and super-soft high-performance foam to deliver a breathable and luxurious sleep experience. Materials: four layers of luxe artisanal cotton, 1.5" of super-soft high-performance foam SUPPORT DETAILS: Individually wrapped coils significantly reduce partner disturbance. Wrapped coils are individually encased so they each respond independently to pressure. Any movements you or your partner make during the night, such as adjusting your sleep position, are isolated to only the coils directly beneath you. This enables you and your partner to sleep more soundly throughout the night. Materials: 713 coils foam encased, 14.5 gauge BOX SPRING: Shifman's premium mattresses feature 8-way hand-tied box springs. Hourglass-shaped upholstery coils are meticulously tied by hand to ensure that they respond independently to conform to the natural contours of the body. These coils maximize comfort by absorbing the body's weight to provide strong, flexible support, durability and extraordinary comfort for the ultimate sleeping experience. Made from Canadian spruce, Shifman's premium box springs feature furniture-grade upholstery coils, the finest imported Italian twine, elegant gold-plated metal corner guards, Belgian damask covers, as well as all-natural cotton padding.
