The O'Conner brings you luxurious, contouring comfort, and elevated support in an adjustable-friendly mattress. To regulate temperature, we've added advanced technology like our Glacier Phase Change Cooling Cover and Englander's exclusive 3° Cooling Coils. Also inside is our pressure relieving 100% Natural Talalay Latex. These comfort layers provide a cloud-like feel coupled with a calming transition for pressure-relief and contouring comfort— with all the healing and anti-inflammatory properties of Natural Talalay Latex. For world-class comfort and support this mattress has contouring, comfortable fabric-wrapped springs and our exclusive Englander edge technology, a full perimeter system eliminates that roll off feeling and provides a consistent sleep service across the entire mattress.
