What Is an Alaskan King Bed?

An Alaskan King mattress measures 108 x 108 inches. It’s the largest size available on the market for both mattresses and bed frames. 

What Is an Alaskan King Bed

Such a mattress can comfortably fit 4 adults and would come in handy if you have a big family who enjoys extra-comfortable lounging. Alaskan King also works for parents who often co-sleep with their kids, as this size can fit 2 adults and 2 children (maybe more, depending on their size, of course).

How Much Does an Alaskan King Mattress Cost?

While the price would depend on a range of factors (including the materials used, the design, and the warranty coverage), most Alaskan King mattresses cost between $2,000 and $7,000.  There will also be a shipping fee, most likely, as this size is quite challenging to transport.

What Is the Best Type of Alaskan King Mattresses?

While the Alaskan King bed size isn’t that common, there are still plenty of options to choose from. But to understand which one would be the most suitable, it’s important to distinguish between the main mattress types. So, here are the most common options:

  • Innerspring. Spring mattresses can usually deliver sturdy support all across the surface. That’s why they are often considered the best option for heavier sleepers. Additionally, innerspring models belong to the cheapest category. And that may come in handy for budget shoppers, as Alaskan King bed prices can be overwhelming sometimes. It’s also worth mentioning that innerspring models allow for improved breathability and thus, sleep cool. At the same time, spring mattresses aren’t that good in terms of pressure alleviation. Therefore, they don’t usually work for side sleepers or users who have sharp pressure points.  
  • Foam. Foam mattresses (whether it’s memory or cheaper polyurethane foam) excel at redistributing the sleeper’s weight evenly and relieving pressure. These mattresses are cradling and often feel like a deep warm hug. This, however, often makes them sleep hot (plus, foam tends to trap heat). Therefore, for hot sleepers, it might be a good idea to choose foam mattresses that use gel particles for cooling or have a breathable open-cell structure.
  • Latex. Derived from rubber tree sap, latex makes a great option for mattress layers thanks to its conforming abilities. It can redistribute the weight evenly to avoid pressure build-up (1). And the best part is, latex isn’t that hugging and does not restrict movement (unlike foam). It doesn’t sleep hot either. However, latex mattresses are also among the most expensive ones (this may be explained by their impressive durability). And given the fact that Alaskan King bed prices are pretty high, getting a latex mattress in that size can put a real strain on some budgets.
  • Hybrid. As the name suggests, hybrid mattresses use combined materials. Usually, they include wrapped coils (for support) and foam or latex (for comfort layers). Hybrid mattresses typically have a very balanced feel. They can guarantee reliable support but also work to relieve pressure. They can be quite expensive, though. Additionally, because hybrids often have multiple layers, they can be quite tall. Combined with an impressive Alaskan King size, such mattresses may end up looking super bulky.

Other Aspects to Consider to Make Shopping for an Alaskan King Mattress Successful

Shopping for an extra-big mattress may be challenging. Unlike most mattress sizes, Alaskan King isn’t that common or widely available. That’s why it’s often hard to predict what shoppers may receive in the end.

Consider to Make Shopping for an Alaskan King Mattress

  • Warranty. Needless to say, an Alaskan King mattress is a serious investment. Naturally, extended warranty coverage would protect this investment better. The conditions of the warranty matter even more, so it’s crucial to study them before finalizing the purchase.
  • Budget. Since this is the biggest mattress size, Alaskan King bed prices also can be pretty high. A good trick to prevent overspending is setting a specific budget right from the start. This would also help shoppers figure out which mattress size they could afford (the bigger the bed is, the more expensive it’s going to be). In some cases, it’s better to settle for a smaller mattress than to strain one’s budget.
  • Height. And this aspect applies to both the mattress and the bed frame. Shoppers need to remember that Alaskan King mattresses can be very bulky and tall. Paired with a high-profile bed frame, they can force sleepers to literally climb onto the bed every night. Therefore, shoppers need to check the height of the mattress to make sure it will work with their current (or desired) bed frame.
  • Delivery and set-up. Naturally, Alaskan King mattresses are big and heavy. They can’t fit through most doors, so it might be a good idea to get a mattress-in-a-box model (or a mattress that comes with separate parts to assemble). Most companies offer delivery to the shoppers’ door. Anything extra would cost more (like delivering to one’s room of choice and unpacking). 
  • Trial. Because most of the mattress companies make Alaskan King models on demand (it’s a custom size, after all), they usually don’t offer a sleep trial. Returning a mattress like that may also be quite challenging. That is why many shoppers give it a lot of thought before committing to the Alaskan King size.
  • Room requirements for an Alaskan King bed. Alaskan King mattresses measure 108 by 108 inches. Needless to say, not every bedroom can accommodate such a mattress. The recommended room size for Alaskan King is 12 x 12 ft. or bigger. This should be enough to allow users to walk freely around the bed.
  • Bedding. It can be challenging to find suitable bedsheets for an Alaskan King mattress. Sometimes shoppers get the needed size from the mattress manufacturers themselves, and sometimes users need to have those sheets custom made. It’s crucial to consider this aspect, as it can make the task of finding bedsheets for the new mattress pretty daunting.

  • natural cotton cover for improved breathability and cooler sleep;

Being among the best Alaskan King mattresses, the Big Mattress Classic seems like it was made to impress. First of all, this is an all-foam model. This mattress is adaptive and feels like it's drawing the tension away from the body. Additionally, the Big Mattress Classic is very sturdy, even the small details like cover fabric or stitches.

  • easy to set up thanks to the convenient zipper system;
  • adjustable firmness on both sides for both the comfort layer and the base to offer more comfort variations;
  • latex + gel memory foam comfort layer for cooler sleep.

Another great Alaskan King bed that deserves your attention, in my humble opinion, is this model by Mattress Insider. It can fit your whole family and also make everyone feel comfortable.
Alaskan King bed by Mattress Insider allows for firmness adjustments as well. You can flip the base (each of the sides) to make it feel softer or firmer. You can also flip the comfort layer. The quilted side uses memory foam and feels softer to the touch. The other side uses latex and feels firmer and more resilient. My wife and I both enjoyed the quilted side more, but we flipped the base (I picked the firm side and my wife chose the soft base side).

You can buy this Alaskan King bed on the Mattress Insider’s website. The company offers free FedEx Ground Shipping.

What Makes a Good Alaskan King Bed Frame?

One of the most important aspects is the sturdy construction, of course. Central support beams and extra legs are a must for an Alaskan King size.

Next, customer-friendly shipping conditions are always a huge bonus. Carrying an Alaskan King bed frame inside and into the bedroom may require a lot of effort (and help). The good news is, some companies offer White-Glove delivery with their Alaskan King bed frames (typically, for an additional fee). This service usually includes delivery to the room of your choice, unpacking, and disposing of the debris.

A quick note: it’s crucial to keep in mind that an Alaskan King bed frame won’t fit into just any room. So, users who aren’t sure their bedroom would be enough might want to opt for a Wyoming King bed, which is also pretty spacious.
