Ideal for firm support seekers, the Therapedic Cressida mattress features sleep technologies that will bring both comfort and restoration to your body while you sleep. TheraWrap Elite coils inside are individually wrapped to flex and conform independently of each other, reducing motion transfer and eliminating partner sleeping disturbance. To improve the transition of getting in and out of bed, a TheraFoam encased edge system provides tremendous edge support in addition to extra surface space. As an added feature, this mattress is constructed with copper-infused TheraCool MemoryTouch gel technology. The microscopic copper particles naturally protect against viruses to prevent the spread of odors and stains, while copper's powerful conductivity complements the gel to dissipate excess body heat. Extra firm performance foams included provide long-lasting durability and support. The GlacierTouch fabric cover on top stays cold to the touch to ensure a cool and comfortable rest. 15 Year Limited Warranty.
