What Is an Alaskan King Bed?

Alaskan King bed is the biggest bed size amongst all commercially made beds, which means an Alaskan king size bed happens to dwarf all the rest of the existing bed sizes available in the market!

However, it has not always been like that. It was only after the 1960s that bigger bed sizes like the king and California king started getting standardized. As people’s homes and rooms grew, the demand for ultra-large beds also hiked. And that’s how the Alaskan king bed size came into the picture.

How Big Is An Alaskan King Bed Mattress?

You might be wondering– “How big is an Alaskan king bed mattress exactly?” 

This monster measures about 9 feet by 9 feet, meaning 108 inches by 108 inches! Needless to say, this makes it the biggest mattress size one can ever buy. Think about it this way – an Alaskan king bed mattress can accommodate four grown-ups comfortably while still leaving enough space for a doggo! It’s that big!

What Are the Benefits Of Alaskan King Bed?

Below, we list a few benefits of Alaskan king beds:

  • Allows co-sleeping 

These gigantic beds are brilliant for families who practice some kind of co-sleeping arrangement. Co-sleeping promotes restorative sleep cycles, but it also helps working parents reconnect with their babies. Also, sleep-sharing makes it easier for parents to respond to their babies if they need something in the middle of the night. 

  • Your go-to fun place

Imagine having a huge centralized and comfy place for your family to spend their best time! Be it gossip sessions, storytimes, cousins’ nights, movie nights, or playing cards together – the Alaska king bed can be your go-to place for all the fun times. 

  • More space for couples

Couples who move a lot at night, plus-sized couples, those who enjoy more personal space, and those who do not like motion transfer – all can have access to sufficient space in an Alaskan king bed. 

  • Easily accommodates pets

As a pet owner, you cannot predict when your four-legged friend will come and start cuddling over. The Alaskan king bed dimensions will allow you to enjoy a sound sleep with your pets.

Things to Consider When Buying an Alaskan King Bed

Before you go ahead and buy an Alaskan king bed, don’t forget to consider the following things:

  • Accessibility

Your room must be spacious enough to lodge an Alaskan king mattress conveniently. Introducing these mattresses in rooms measuring less than 16 feet by 16 feet will block space and make it difficult to move around. So, keep in mind the Alaskan king bed measurements. 

  • Bed frame

An Alaskan king bed is not your regular bed. Hence, you will not easily find a ready-made Alaskan king bed frame or foundation. Therefore, it is advisable to plan a custom foundation or bed frame to avoid misfits.

  • Mattress type

As with any other mattress size, you need to decide which mattress material is best suited for you before purchasing. For instance, if you plan to sleep on your bed daily, you’ll want a more comfortable and supportive material. On the flip side, if you wish to convert your basement into a lounge area, a cheaper foam variant might do the trick. 

  • Budget

Make sure you consider your budget because different Alaskan king beds cost you differently. Depending on their thicknesses and quality, the Alaskan king bed mattress prices vary distinctly (by thousands of dollars).

Other Giant Bed Sizes

Two other commonly preferred giant bed sizes are – California kings and double kings. Below, we compare them both with the Alaskan king:

Alaskan King Bed vs California King Bed 

The most significant difference between an Alaskan king bed and a California king is – that while the former is the largest bed size ever created in the history of beds, the latter is the largest amongst all standard bed sizes. 

The Alaskan king bed measures about 108 inches by 108 inches. However, the California king measures 72 inches by 84 inches. So the major difference between an Alaskan king bed vs California king is that an Alaskan king has sufficient space for an entire family. In contrast, the California king is suitable only for taller couples. 

Alaskan King Bed vs Double King Bed 

A double king mattress is essentially the widest of all mattress sizes. With dimensions of 152 inches by 80 inches, it surpasses the Alaskan king considerably in terms of its width. So basically, a double king bed is 44 inches wider and 28 inches shorter than the Alaskan king. Remember, you need to have an exceptionally wide space to fit this one inside your room.
