With the Picasso Mattress, three inches of PureGel™ Plus Gel Memory Foam covers the entire mattress from edge to edge and from head to foot. Memory foam conforms to your body to alleviate pressure points. Meanwhile, the core of this mattress takes support very seriously. The innerspring Comfort Support Core features 7-inch coils that are individually encased to ensure quietness and custom compression to support the sleeper’s body shape. This mattress also includes two inches of Quick Recovery Convoluted Foam (QRC) to create a resilient, fast rebound when weight is removed. High density foam runs around the border to support you well when you sit down on the edge or sleep near the edge. The removable cover is made with a Tencel/poly blend fabric. Machine wash as needed in a washer with at least 4.0 cu. ft. of capacity.
