Collection: King Size Mattresses

Big on Space, Even Bigger on Comfort

A king-size mattress isn’t just a place to sleep—it’s a space to stretch, reset, and fully relax. Whether you’re co-sleeping with a partner, sharing your bed with pets or kids, or simply enjoy the feel of a sprawling sleep surface, a king bed gives you the freedom to move without disruption.

At Mattressville, our King Mattress Collection showcases a wide range of premium brands and build types, curated for those who want the best of both size and support.

Space Meets Support: Top Picks in King

For those who want handcrafted Canadian quality, the Marshall Euro Top Luxury Firm Mattress is a standout. Featuring individually wrapped coils and breathable natural materials, it offers zoned support and subtle contouring. The euro top gives it a plush finish, while still delivering the firmness needed for proper alignment.

Craving an elevated mix of cloud-like comfort and firm foundation? The Stearns & Foster Pillow Top Luxury Firm Mattress delivers. With high-density IntelliCoils®, enhanced edge support, and precision tailoring, it’s ideal for couples who want to minimize motion transfer while enjoying a luxury hotel feel.

On the other end of the firmness spectrum is the Aireloom Tight Top Extra Firm Mattress – Pacific Palisades, built for those who like their sleep surface ultra-stable and supportive. Crafted with Aireloom Lift™ technology and dense, breathable materials, it’s a favorite among back and stomach sleepers who need reliable posture control.

Prefer pressure-relieving foam that adapts like nothing else? The TEMPUR-Align Soft Mattress wraps you in a cloud of NASA-engineered TEMPUR® material. It conforms to your exact shape for deep, undisturbed rest—especially helpful for side sleepers and those dealing with joint sensitivity.
