What Is an Alberta King Bed?

Dimensions: 96-by-96 inches

The Alberta king bed is the second-largest king mattress. Measuring 8-by-8 feet, the Alberta king mattress can comfortably fit two adults, two children, and two pets, making it a great option for co-sleeping arrangements. 

Compared to different king sizes, the Alberta king is smaller only than the Alaskan king and measures 20 inches wider and 16 inches longer than a standard king size mattress. 

Alberta vs. Vermont vs. Alaskan King Mini Beds

While often referred to by different names, it’s key to note that the Alberta king, Vermont king, and Alaskan king mini mattresses are identical in size, all measuring 96-by-96 inches. This is mainly due to different manufacturers using different names to differentiate their products. But don’t fret, they’re all one and the same. 

Who Is the Alberta King Size Best For?

Given its exceptionally large size, the Alberta king is suited for families who co-sleep together or those who are looking for a luxuriously large bed to fit a bigger-than-average room. 

An Alberta king mattress is best for:

• Couples looking for something slightly smaller than an Alaskan king
• Families with multiple children who co-sleep together
• Those looking to fill the space of an extra-large room
• Those looking for the luxury feel of an oversized mattress

The Alberta king mattress is the perfect middle ground between the Wyoming and Alaskan king sizes, making it a good bed size for couples. If you’re looking for something slightly larger than a Wyoming king size mattress, which measures 7-by-7 feet, yet not quite as large as the biggest king mattress at 9-by-9 feet, then the Alberta king might be right for you. 

Benefits of an Alberta King Bed

One of the more unique features of the Alberta king bed is its shape. While standard mattress sizes are typically rectangular, the Alberta king is perfectly square — allowing for easier arrangement. Its expansive size also fits most body sizes and accommodates multiple sleepers. Here are the top benefits of choosing an Alberta king mattress:

• Perfect middle ground between Wyoming and Alaskan king beds: The Alberta king measures 8-by-8 feet, making it 1 foot longer and wider than the Wyoming king and 1 foot shorter and narrower than the Alaskan king bed. 
• Great for co-sleeping with multiple children: The Alberta king bed is a good choice for families, providing ample room without feeling cramped. It can comfortably fit two adults, two children, and two pets. 
• Suitable for most body sizes: With a surface area of 64 square feet and a weight limit of over 2,000 pounds, the Alberta king bed ensures comfortable sleep for most body types, including taller or larger individuals. 
• Offers a luxurious oversized look: An Alberta King can be the centerpiece of your room, creating a spacious feel. Its grand size complements large rooms, adding sophistication to your primary or vacation home. 

Alberta King Mattress Size Comparison

The Alberta king bed is one of the largest king mattresses available. Measuring wider than most other non-standard king sizes, it offers just over 21 square feet more surface area than a standard king mattress. 

Here are the largest mattress size dimensions to choose from:

Alberta King vs. California King

California King: 72-by-84 inches

While a California king offers more legroom than a standard king, the Alberta king takes spaciousness to a whole new level. Measuring 8-by-8 feet, the Alberta king mattress is 2 feet wider and 1 foot longer than the California king, providing ample room for a small family. 

Unlike the California king mattress, which is rectangular and the most narrow of all non-standard kings, the Alberta king’s size and square shape create a balanced and luxurious feel in large rooms. 

When comparing the Alberta king to a standard king or California king mattress, it offers room for two adults, two children, and two pets with a large surface area of 64 square feet. 

Alberta King vs. King

King: 76-by-80 inches

The standard king fits two adults, but the Alberta king bed is the better choice when you need room for the whole family. While the standard king size measures 76-by-80 inches, the Alberta king mattress provides 20 extra inches of width and 16 inches of length. 

The Alberta king’s large size allows a family of four to fit comfortably with additional room for pets. But the Alberta king isn’t just for families. It’s also perfect for all types of couples’ sleeping positions, which you’ll appreciate if you enjoy sprawling out or have a restless partner. 

Alberta King vs. Texas King

Texas King: 80-by-98 inches

The Texas king bed is most similar to the California king, as it is longer than it is wide, making it a better option for taller people or those who sleep with pets at the foot of the bed. The Alberta king mattress is 16 inches wider and 2 inches shorter than the Texas king.

The difference between the two oversized mattresses is namely their shape. If you prefer a longer bed that is wider than the California king, then the Texas king might be right for you. If you’re looking for more space all around, then the Alberta king might be better suited for you.  

Alberta King vs. Wyoming King

Wyoming King: 84-by-84 inches

The Wyoming king mattress measures 84-by-84 inches, making the Alberta king 1 foot wider and 1 foot longer than the Wyoming king. Both beds are square rather than the traditional rectangular mattress shape, which offers a luxurious oversized look. 

Room size and preferred mattress size are the two main reasons to choose the Alberta king over the Wyoming king. If you have a room larger than 12-by-12 feet, or you simply prefer the extra space based on your family size or sleeping preferences, then the Alberta king may be the better choice. 

Alberta King vs. Alaskan King

Alaskan King: 108-by-108 inches

The Alaskan king is the largest of the king mattresses, measuring 9-by-9 feet, but the Alberta king is close behind at 8-by-8 feet. Both mattresses are good for co-sleeping arrangements or for filling up a large room, but the Alaskan king is 1 foot wider and longer than the Alberta king. 

The biggest difference between the Alberta and Alaskan king is that the Alaskan king can fit an additional adult with extra legroom for large pets. If you’re looking to sleep multiple adults and children, then the Alaskan king is a better choice. Otherwise, if your bedroom is between 13 and 15 feet in width and length, the Alberta king may be a better fit. 

Considerations When Buying an Alberta King Bed

Choosing the right mattress is an important decision. After all, it impacts everything from your comfort to your overall sleep quality. While choosing the right size mattress is one important piece of the puzzle, you should also consider aspects like your sleeping position and temperature regulation needs. 

Availability

While there are many benefits to buying an oversized mattress, keep in mind that they can be harder to come by. This is especially true for Alberta king mattresses, as they are less common than most other king beds. You’ll likely have to find a specialty retailer that sells the Alberta king size, plus accessories to go with it. That includes a non-standard king size bed frame, sheets, and pillows. 

Family Size

If you’re planning to co-sleep, consider how many people can comfortably fit in your bed. An Alberta king mattress can fit two adults and two children, plus two pets at the foot of the bed, making it a good choice for small families. 

While an Alberta king offers an abundance of space for co-sleeping, it’s also great for couples who want ample room to move around. With 64 square feet of surface area, you and your partner can spread out without worrying about disturbing one another. 

Room Space

The Alberta king bed fits best in a 15-by-15 foot room to give you that luxurious feel without feeling cramped. Since the Alberta king bed is square unlike most standard rectangular mattresses, you should also consider your room configuration. An extra-large bed will look best in the center of the room rather than pushed to one side. 

Preferences

The type of bed you choose, such as a foam or hybrid mattress, makes all the difference in your sleep quality. While a memory foam mattress provides pressure relief and contours to your body’s shape, a hybrid mattress tends to offer more support and breathability. This is important, as the type of mattress you choose impacts the cost and availability of an Alberta king bed. 

Knowing your comfort preferences can help you decide which mattress type works best for you and your family. You may also prefer one over the other depending on your sleep position. 

Cost

Oversized king mattresses are typically more expensive than standard beds due to their sheer size and the cost of materials. An Alberta king bed typically costs between $2,500 and $3,500. 

That said, how much you spend on a mattress also depends on the type of bed you choose. Foam and innerspring mattresses are on the more affordable end — ranging from $450 to $1,300 — while hybrid mattresses tend to cost slightly more because of their higher quality — ranging from $1,200 to $3,000. 

Sleep Style

Whether you’re learning how to sleep on your back or you prefer to move around a lot at night, your mattress size should suit your sleep type. The best part of an extra-large mattress is that it accommodates just about any sleep position and a range of body sizes. 

This can be especially helpful if you and your partner are on different sleep schedules or you toss and turn a lot. The extra space of an Alberta king bed helps minimize sleep disturbances for better rest. 

Sleep Better With a Supportive Mattress From Purple

Of all the different king size mattresses, the Alberta king bed, also known as a Vermont king, does not disappoint when it comes to spaciousness. It offers room for a family of four, plus additional space at the foot of the bed for multiple pets. 

Despite the grandeur of an extra-large bed, most couples find that a standard or California king size bed offers more than enough space. In fact, the average bedroom size is 143 square feet (11-by-13 feet), which is too small to accommodate an Alberta king. 

If you’re looking for a standard king size mattress rather than an oversized bed, Purple offers king, split king, and California king sizes to meet your needs. If you’re looking for luxury comfort, Purple’s GelFlex® Grid provides adaptive support and relief that won’t overheat for restful sleep, night after night.
