Experience the unmatched luxury of the Alaskan King Bed — the largest standard mattress size available. Designed for maximum space, deep sleep, and family comfort, it's the ultimate bed for those who dream big. 

How Does the Alaskan King Compare to Other Oversized Beds? 

When choosing an oversized mattress, it's important to understand how the Alaskan King stacks up against other popular options like the Wyoming King, Texas King, and California King. Each mattress offers unique dimensions and benefits tailored to different needs—whether you're a tall sleeper, have a large family, or simply want more space to stretch out. The table below breaks down the differences so you can find the perfect fit for your lifestyle and bedroom. 

The Alaskan King Bed is not just a larger mattress — it’s a lifestyle upgrade. Designed for those who refuse to compromise on comfort, this bed redefines what restful sleep can look like. If your current mattress leaves you feeling restricted, crowded, or constantly disturbed, the Alaskan King offers a refreshing solution through pure, uninterrupted space.

This bed is perfect for:

• Families who co-sleep with kids or pets and need room to spread out without kicking elbows
  
  

• Couples who value personal sleep space, allowing each partner to move freely throughout the night
  
  

• Tall individuals who find their feet hanging off the edge of standard beds
  
  

• Luxury homeowners looking to make a bold statement in a master suite or oversized bedroom
  
  

• People with health issues like joint pain, back pain, or sleep apnea — the extra space enables better positioning and circulation
  
  

More than just functional, the Alaskan King represents peace of mind. It’s an invitation to stretch out fully, rest deeply, and wake up feeling like royalty — every single morning.

An Alaskan King Bed is a premium product, and the price reflects that. On average, the mattress alone can range from $3,500 to $7,000, depending on materials, firmness level, and customization. Bed frames, adjustable bases, and oversized bedding are typically sold separately and can add another $1,000 to $4,000 to the total.

While the upfront investment is significant, many buyers view it as a long-term decision — one that transforms their sleep quality, family routines, and even the look of their bedroom.

Before ordering, it’s important to consider not just your bedroom size, but your hallways, doorways, and stairs as well. The Alaskan King measures 108" x 108", so delivery and setup can be tricky without proper planning.

Most people with modern homes can accommodate it with a room size of at least 12x12 feet, but for optimal layout and walking space, 14x14 or larger is ideal. Split mattresses and modular bed frames are often used to ease transportation and setup.

If space, comfort, and long-term sleep quality are priorities in your life — the Alaskan King is absolutely worth it. For co-sleeping families, tall individuals, or those simply craving more freedom to sleep how they want, this bed delivers.

It’s not just about size — it’s about how sleep feels. The ability to stretch out without borders, rest undisturbed, and reclaim sleep as a sanctuary is why many consider the Alaskan King an investment in their well-being.

1. What are the exact dimensions of an Alaskan King Bed?

An Alaskan King Bed measures 108 inches by 108 inches, making it the largest standard oversized mattress on the market. That’s 9 feet wide and 9 feet long — significantly larger than a California King (72" x 84") and even bigger than a Wyoming King (84" x 84"). It offers ample space for couples, families, or anyone who values personal sleep space.

2. Can I buy an Alaskan King Bed from regular mattress stores?

Most mainstream mattress retailers do not carry Alaskan King Beds due to their unusual size. However, you can easily order one online from specialized manufacturers like Big Mattress Co., Mattress Insider, or AlaskanKingBeds.com, all of which offer custom sizing and nationwide delivery.

3. Will it fit in a regular bedroom?

Not always. A minimum bedroom size of 14x14 feet is strongly recommended to fit an Alaskan King comfortably, leaving space for walking around the bed and additional furniture. Always measure your room — and doorways — before ordering.

4. Is there a split version of the Alaskan King?

Yes. Some manufacturers offer a split Alaskan King, which is essentially two 54" x 108" mattresses. This makes it easier to move through tight doorways and staircases, and it also allows couples to customize firmness levels or use adjustable bases independently on each side.

5. What kind of bed frames work with Alaskan Kings?

You’ll need a custom or oversized frame specifically designed to hold a 108" x 108" mattress. Many companies that sell the mattress also sell compatible bed frames, including platform bases, adjustable bases, and heavy-duty foundations built to support the added weight and width.

6. Do regular sheets and comforters fit an Alaskan King?

No. You’ll need to buy oversized bedding designed for Alaskan King dimensions. Some manufacturers bundle custom-fitted sheets and oversized comforters with the mattress, or you can order them separately from specialty bedding retailers.

7. How much does an Alaskan King Bed cost?

Prices vary based on materials and customization, but most Alaskan King mattresses cost between $3,500 and $7,000. Bed frames and bedding are additional and can push the total investment to $5,000–$11,000 or more.

8. Is an Alaskan King good for people with back pain or joint issues?

Yes — the extra surface area allows you to reposition comfortably without hanging off the edge or disturbing your partner. Many buyers with chronic pain, arthritis, or sleep apnea find that the space allows for more restorative, uninterrupted sleep.

9. Can I use two mattresses to create an Alaskan King?

Technically, you could place two Twin XL or Full XL mattresses side-by-side, but it won’t match the dimensions or unified feel of a true Alaskan King. If flexibility is your goal, consider the split Alaskan King offered by specialized sellers.

10. Is the Alaskan King Bed worth the money?

If you value space, comfort, and luxurious sleep — absolutely. For growing families, couples with pets, or anyone craving extra room, the Alaskan King isn’t just worth it — it’s often life-changing. It turns your bedroom into a true sanctuary of rest and relaxation.

The Alaskan King Bed is more than just the largest mattress on the market — it's a bold commitment to redefining what comfort means in your home. In a world where most people settle for "just enough," choosing a bed that spans nine feet in both directions signals something more: that your sleep, your peace, and your well-being are non-negotiable. It's not just about space — it's about reclaiming the freedom to sleep without restrictions, to move without bumping into a partner, to rest with pets and children without sacrificing your own comfort. It’s a bed that respects your lifestyle, not one that forces you to shrink into it.

And yet, the Alaskan King isn’t for everyone — and that’s precisely the point. It’s for those who dream big, who live fully, who design their spaces with intention. It transforms a master bedroom into a haven, a private retreat where stress ends and restoration begins. Yes, it requires space. Yes, it comes at a premium. But for those who value serenity, luxury, and deep, uninterrupted rest, the investment pays off every single night. If you're ready to sleep like royalty, this isn’t just a mattress — it's a revolution in how you rest. Click here to explore top mattress brands and frame options.
