QUILTING LAYER:Shifman mattresses feature its exclusive Sanotuft® technique, which produces a smooth buttonless tuft that is hand-sewn from top to bottom, locking all sumptuous upholstery layers and innerspring securely in place. This process alleviates shifting and bunching of material layers, allowing your mattress to stay comfortable longer. Materials: Cotton, polyester, viscose, polyamide COMFORT LAYER:Seven inches of sculpted natural latex respond to your individual body contours and reduces the pressure that causes you to toss and turn for a deeper, sounder sleep. A 3-in-1 fiber combines natural New Zealand wool, alpaca, and silk for breathability, durability, and comfort to keep you warm in the winter and cool in the summer. The pillow top features 5" of super-soft sculpted natural latex, layered with two layers of plush New Zealand wool, fine silk, and deluxe alpaca, delivering a cloud-like feel with exceptional breathability and luxurious softness. Materials: Latex, New Zealand wool, silk, alpaca SUPPORT DETAILS:The latex core relieves pressure points and promotes proper spinal alignment, to help reduce tossing and turning throughout the night, resulting in a deeper and more restful sleep. Latex is inherently breathable and temperature-regulating, creating a cool and comfortable sleep environment. The premium latex edge rails not only enhance the overall structural integrity of the mattress but also provide a luxurious feel and enhanced comfort along the edges.
