The Grand Reserve Ultra Plush Pillowtop is the crown jewel of the Jamison Resort Hotel Collection — and one of the finest mattresses available at any independent mattress retailer. At 15 inches, every layer is a premium material: IceTech™ Cooling Fabric on the surface provides active thermal cooling. MemoryQuilt™ Foam w/Gel delivers gel-infused memory contouring right at the cover. A dedicated CopperFusion™ Memory Foam pillowtop adds deep, antimicrobial pressure relief above the main upholstery. AeroSpring Latex™ in the upholstery provides breathable, bouncy latex cushioning that keeps air flowing and prevents the mattress from sleeping hot. The UltraEdge Secure™ Pocket Coil System below delivers the hotel-grade motion isolation, zoned support, and edge reinforcement that make sleeping on this mattress feel like the best night of sleep you've ever had — every single night.
