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:Five inches of sculpted natural latex responds to your individual body contours and reduces the pressure that causes you to toss and turn for a deeper, sounder sleep.
