What Is The Biggest Mattress?

When we think of grandeur in the world of sleep, the biggest standard mattress size is the Alaskan King, measuring a majestic 108 inches by 108 inches (9 feet by 9 feet). Its square shape provides ample space for multiple sleepers, families, and those who crave extra room to stretch out. Beyond its expansive surface, the factors that contribute to its size, including frame requirements, room size, and bedding considerations, are equally important to understand.

Understanding Mattress Sizes

To truly appreciate the enormity of an Alaskan King mattress, it’s essential to have a grasp of other mattress sizes. Mattress sizes range from small, such as the Twin at 39 inches by 75 inches, to the more common Queen size at 60 inches by 80 inches, and all the way to the impressive California King size at 72 inches by 84 inches. Even among large mattresses, the Alaskan King is a significant step up in terms of surface area, outclassing other oversized options like the Texas King and Wyoming King.

Standard Mattress Size Chart

Let’s look at a size comparison to put things into perspective:
– Twin: 39″ x 75″
– Twin XL: 39″ x 80″
– Full: 54″ x 75″
– Queen: 60″ x 80″
– King: 76″ x 80″
– California King: 72″ x 84″
– Texas King: 80″ x 98″
– Wyoming King: 84″ x 84″
– Alaskan King: 108″ x 108″

As you can see, the Alaskan King is significantly larger than even the largest standard sizes, dwarfing both the King and California King.

Who Needs an Alaskan King Mattress?

The Alaskan King mattress isn’t for everyone due to its sheer size. However, it’s perfect for certain sleepers:
– Families who co-sleep: If you share your bed with multiple children, the Alaskan King can accommodate everyone comfortably.
– Taller individuals: For those over six feet tall, the Alaskan King offers plenty of room to lie straight without having feet dangle off the edge.
– Pet owners: If your pets sleep with you and you need more space, this size provides ample room for you and your furry friends.
– Anyone who enjoys space: If you simply value a spacious sleeping environment, the Alaskan King delivers luxurious comfort with room to spare.

Considerations Before Purchasing an Alaskan King Mattress

Choosing to invest in an Alaskan King is a significant decision and requires considering several factors.

Room Size

Before purchasing an Alaskan King mattress, ensure your bedroom can accommodate it. Ideal room dimensions should be at least 16 feet by 16 feet, allowing for walkaround space and additional furniture. Measure your room to avoid any costly mistakes.


Consider the journey from your doorstep to the bedroom. Can a mattress of this size navigate through your hallways, doorways, and stairwells? Some Alaskan King mattresses come in sections or require on-site assembly to navigate tight spaces.

Bed Frames and Accessories

You may need to custom-order a bed frame, sheets, and mattress protectors for your Alaskan King since standard sizes will not fit. This can add to the overall cost and time it takes to fully set up your new sleeping space.


Due to its size and the specialized production process, an Alaskan King mattress is typically more expensive than smaller mattresses. The investment extends to sheets, bed frames, and comforters, which are all specially made for this size.

Moving Considerations

An Alaskan King mattress is cumbersome and can be a challenge to move. If you relocate frequently, this mattress type might not be practical.

Sleeping on a Mattress Fit for a King

Sleeping on an Alaskan King mattress can feel like a luxury each night. The expansive space allows for a complete stretch and the opportunity to find the perfect sleeping position without disturbing your partner.

Health and Sleep Quality

For those with sleep disturbances like insomnia or sleep apnea, the extra space can improve overall sleep quality. Couples who have different sleeping patterns or preferences may find that the extra space allows one to get up without waking the other.

The Sleep Experience

The sensation of sleeping on such an expansive mattress can be likened to staying in a luxury hotel every night. The lavish space and comfort can result in a deeper, more restful sleep.

Creating a Restful Sanctuary

An Alaskan King bed transforms a bedroom into a sanctuary of rest and relaxation. The bed can become the centerpiece of the room, dictating a luxurious and grand atmosphere.

Decor and Styling

The bed’s substantial size means the other elements in the room should be proportional to avoid any piece being dwarfed. Carefully select large furniture and decor to create visual balance in the space.

Bedding Options

Opt for high-quality bedding materials such as Egyptian cotton or silk for the ultimate luxury experience. Although bedding for an Alaskan King is a significant investment, it’s crucial for maximizing the comfort and longevity of your mattress.

Finishing Thoughts

The Alaskan King mattress is the epitome of comfort and luxury in the world of sleep. Its expansive size ensures that each person has their personal space, which can contribute to better sleep quality and overall well-being. While it may not be suitable for every household due to its size and cost, for those with ample space and the desire for a grand sleeping environment, it’s a worthwhile investment.

When considering an Alaskan King mattress, take into account your lifestyle, room size, bedding and accessory needs, and moving concerns. With the right preparations and considerations, this mattress can be the ultimate sleep solution for those who crave space, comfort, and a touch of majesty in their nightly retreat.
