History on the Alaskan King Bed

The king-sized bed was the king of all beds up until about the 1960s when the California King was introduced. History tells us that in past centuries, large mattresses were a thing dating back to even the 16th century. In the past decade, demand for mega-beds and custom mattresses has grown significantly. Sleep needs have been changing and so larger mattresses have continuously developed in the past 50 years. Although a king sized mattress is now a standard size, the Alaskan King is most often customized for an individual’s specific needs. 

So How Big is an Alaskan King Bed?

While a King bed measures about 80” x 76,” an Alaskan King bed is a whopping 108” by 108.” For some, the King bed is simply not cutting it anymore. People are craving more space while sleeping with a significant other—with hopes that a larger bed will limit motion transfer and sounds.

For parents that have adopted co-sleeping into their family lifestyle, squeezing pets and children into a King is still pretty tight. Others just want the biggest and largest mattress they can get their hands on (we don’t blame you). 

According to the Guiness Book of World Records, the largest mattress ever recorded was in 2011 by Commissie Zomerfeesten at St Gregorius, Hertme, in the Netherlands. The bed measures approximately 86’ x 54’.

Oversized Mattress Sizes


Is an Alaskan King Bed Ideal For Me?

An Alaskan King bed might be the right fit for:

  • Taller or larger individuals
  • Couples who sleep with children
  • Couples who sleep with pets
  • Couples with varying sleep schedules who want to limit sleep disruptions
  • Those who find a traditional King to be too short
  • Those who find the California King too narrow

There are so many benefits that come with an Alaskan King mattress. First and foremost, a larger bed will allow for more movement and decrease sleep disruption from your partner. Pets and children can fit more comfortably in co-sleeping arrangements. Up to three or four adults can fit in an Alaskan King, or for two, the bed serves as a large sleep oasis. Typically, the large surface area can allow for taller and larger individuals to sleep more comfortably as well.

But when it comes down to it, unless it doesn’t fit in the room, when have you ever heard someone complain that their mattress is too large?

Import Factors to Consider

Most Alaskan Kings will fit in a home, but it is important to measure your bedroom to make sure it will fit properly. Just as important, is measuring doorways and stairways in your home to make sure the bed will fit when it is delivered. Some Alaskan Kings can be assembled in modules to facilitate an easier delivery and set-up.

A larger mattress means you need to find a bed frame and sheets that will also fit your new Alaskan King bed. Many bedding boutiques or manufactures can work with you to customize dimensions. Although sometimes more expensive, custom ordering does not always mean crazy expensive. Online searching may yield some great options, however, if you do not want to go the custom route.

So how should you estimate the bedding dimensions? The 12-16 rule is a great guideline when shopping for a comforter, especially for larger mattresses. You may have noticed that comforters are wider than they are long. Even though a Wyoming and Alaskan bed are square, you will still want a wider comforter. The comforter should hang over both sides of the bed, but the length will only cover the foot side of the bed. The 12-16 rule suggests that you should add 12” for the comforter lengths, and 16” for the comforter width. For a 108” x 108” Alaskan King, your comforter should be about 120” length and 124” width.

What About a Wyoming King Bed?

Our visual comparison photo displays a bed size that measures between a California King and an Alaskan King– a Wyoming King. The Wyoming King measures 84” by 84” and for some, solves the issue of a narrow California King.

A Wyoming King is great for those who want just a little bit of extra space rather than the surplus that an Alaskan King might provide. A Wyoming King is a great choice for those who sleep with small children, and fewer or smaller pets.

It’s essentially the happy-medium of ginormous mattresses. Like the Alaskan King bed, the Wyoming King bed is typically a custom order. Using the 12-16 comforter rule, you would want a comforter that is approximately 96” length and 100” width.

Where Can I Get an Alaskan King Bed?

An Alaskan King bed can be found pre-made by some mattress retailers, but chances are you will not find one in the big-box mattress stores. The best route to go for ordering an Alaskan King bed is a custom order.

If you are going to splurge on a mattress of that size, you might as well custom order it to be exactly to your liking. Many manufactures are willing to work with you so that your covers, foam thickness and densities, and technology is perfected to your desires.
