Clear Day Twin Mattress

The Jamison Clear Day is a firm twin mattress built around a 5.5-inch Ortho-Support foam core that gives the bed its shape and structure. Above that, Cloud Comfort and Ultra Support foam layers work together to take the edge off the firmness without softening the feel. The quilted stretch knit cover includes a layer of gel cooling foam, so the surface sleeps noticeably cooler than standard foam mattresses tend to. At 7.5 inches tall, it fits most standard bed frames and is a straightforward, no-fuss option for a guest room, bunk setup, or first bed.
