Your Side. Your Perfect Sleep.
Choose the comfort that feels right for you. One partner can enjoy a firmer feel while the other prefers something softer. With two mattresses, both sleepers get their ideal comfort—without compromise.
Premium Dual King Setup
King-size space, personalized comfort.
Less Motion. Better Sleep.
With a separate mattress on each side, movement stays more contained. So when your partner turns, gets up, or moves around, you’re less likely to feel it—helping you enjoy a more peaceful night.
Perfect for Adjustable Bases.
Dual King works beautifully with a Split King adjustable base. Each side can move independently, giving both sleepers the freedom to raise, lower, and adjust their side for personalized comfort.
Easier to Move. Made for Modern Living.
Two narrower Twin XL mattresses can be easier to maneuver through doorways, hallways and stairs than one large King mattress.
What is a Dual King?
A Dual King is a spacious King-size sleep setup made by placing two Twin XL mattresses side by side. Instead of sharing one single mattress, each sleeper has their own mattress while still enjoying the generous sleeping area of a King.
This configuration is especially useful for couples who have different comfort preferences, sleep habits, or firmness needs. Each person can choose the Twin XL mattress that feels right for them, while the two mattresses work together to create one complete King-size footprint.
