Why Choose an Oversized Mattress?

More and more households are upgrading to oversized mattresses for both comfort and practicality. If you’ve ever felt cramped in a traditional bed, you’re not alone.

Our oversized mattresses are perfect for:

Families with young children who love to pile into bed
Pet owners with large dogs or multiple pets
Taller or larger individuals who need more sleeping space
Multi-generational households sharing sleep space
Luxury buyers who value comfort, openness, and freedom of movement
Lifestyle-focused customers who want a more flexible and spacious sleep environment

No matter your reason, the goal is the same: more space, better sleep, and a bed that fits your sleep style.

California King

The California King is the refined choice for the sleeper who needs length without the bulk. Measuring 72″ x 84″, it trades 4 inches of width from a standard King to provide 4 inches of essential extra legroom. It’s a specialized silhouette designed for taller individuals who are tired of their feet hanging off the edge, fitting perfectly into narrower master suites. At DeLarkin, we hand-build every California King in our South Carolina factory with high-density foams and cooling materials, ensuring that while the bed is longer, it remains supportive and durable from head to toe for years to come.

Texas King

For those who need an expansive sleep surface but have a bedroom that is longer than it is wide, the Texas King is the ultimate solution. At 80″ x 98″, it is a massive 18 inches longer than a traditional King, making it the premier choice for the tallest sleepers or families who share the foot of the bed with large pets. Its unique rectangular shape creates a grand presence in a master bedroom without the overwhelming width of other oversized models. We engineer our Texas Kings to handle this extended length with precision, providing a consistent, premium feel that standard mass-market retailers simply cannot replicate.

Wyoming King

The Wyoming King offers a perfectly balanced, symmetrical retreat with its 84″ x 84″ square design. This size provides a significant upgrade in both width and length over a standard King, offering that extra “breathing room” for couples who want to stretch out or parents who welcome kids for morning cuddles. Because it is the most compact of the “Big Three” oversized beds, it often fits into standard luxury bedrooms without requiring a home renovation. Built with our laboratory-tested cooling layers, a DeLarkin Wyoming King ensures that even with more surface area, you stay cool and supported in the center of the bed all night long.

Alaskan King

The Alaskan King is the pinnacle of sleep luxury—a staggering 108″ x 108″ masterpiece that transforms a bedroom into a true sanctuary. Offering a full nine feet of width and length, it is the mattress of choice for co-sleeping families, owners of multiple pets, or anyone who desires an uncompromising level of personal space. Hand-crafted to order, our Alaskan Kings utilize specialized support systems to maintain structural integrity across their massive nine-foot span. It isn’t just a mattress; it is a bespoke furniture piece that serves as the centerpiece of a high-end home, providing enough room for the whole family to rest without ever feeling crowded.
