Anyone can enjoy an Alaskan King's expansive sleep space, including:

Couples and Restless Sleepers

Your partner's night-time movements won't disrupt your rest again on an Alaskan King bed. These giant beds offer plenty of personal space for two. Spread out when it's time for sleep, and shifting positions or getting in and out of bed won't affect your partner or vice versa.

Families and Co-Sleepers

Alaskan Kings make bed-sharing possible, even for families with multiple kids. Up to two adults and three to four children—depending on their size and age—can fit on an Alaskan King bed.

Pet Owners

You don't have to sacrifice sleep space when you let your furry friends join you in bed. Alaskan Kings are roomy enough for you and your pets to sprawl out.

Luxury Lovers

An Alaskan King bed makes a statement. It's a lavish bedroom upgrade for anyone with maximalist taste.

At Alaskan King Sleep, we believe hybrid construction is best for oversized beds. Hybrid mattresses combine multiple foam layers with a coil support core, offering soothing comfort and deep support. Hybrid builds also enhance durability, a critical quality for beds as big as Alaskan Kings.

Our mattresses may be massive, but they're meticulously crafted. We design and assemble our mattresses right here in the U.S.A., ensuring the quality and durability that beds this size demand. Our premium Alaskan King mattresses boast these essential features and more:

Cooling– Sleep cool, even if you share the bed with a partner, kids, or pets. Our heat-dissipating covers and breathable foams prevent body heat from building up within the mattress.

Pressure Relief– Our soothing foams cushion your curves and disperse body weight for lower peak pressure around vulnerable joints.

Motion Isolation– The size of an Alaskan King lends itself to uninterrupted rest, but our responsive and motion-absorbing foams take comfort to the next level.

Full-Body Support– Our mattresses have hybrid constriction, pairing cushioning foams with ultra-durable coils for deep support, structure, and strength.
