Get the deep, restful sleep you’ve been craving with the Restonic 14” King Firm Hybrid Mattress. Built for firm support lovers, it combines cooling tech, durable foams, and pocketed coils to fix common sleep frustrations—like overheating, partner motion, and sagging. The dual cooling system absorbs and releases heat so you stay comfortable all night (no more tossing from sweat!). CoolFlow Plush Foam adds a soft, breathable layer that cradles your body without feeling stuffy, while DuraLast Foam keeps the mattress firm and shapely for years—no sagging or lost support. Couples will love the 800 pocketed coils that isolate movement (your partner’s tosses won’t wake you up!), and back sleepers get 25% more lumbar support from the Marvelous Middle. Plus, SuperEdge support lets you sit on the edge without feeling wobbly. Perfect for King-size beds, it gives you and your partner room to spread out while staying cool, supported, and refreshed.
