The Encore® Aubrey Medium Mattress features a soft, gel-infused foam layer that conforms to your shape, providing cloud-like comfort for your body. The VertiCoil system is foam-encased, allowing for a strong border and consistent coverage across the entire surface of the bed, reducing sagging and roll-off. The kid-friendly knit fabric stretches in four directions, allowing you to get the most out of the comfort layers in your bed. 10-Year Limited Manufacturer’s Warranty.
