The Alaskan King Mattress is not your average bed—it’s an oversized sleep sanctuary measuring 108 inches by 108 inches. That’s a whopping 9 feet by 9 feet of uninterrupted stretch space. If you’ve ever felt cramped, kicked, or cornered in bed, this mattress might be the liberation you didn’t know you needed.
Perfect for families, pet owners, or tall individuals, the Alaskan King redefines what comfort can look like. But is it just a flashy upgrade, or is it genuinely worth it? Let’s break it down.
Why the Alaskan King Mattress Is Unlike Anything Else
The Alaskan King is the largest standard mattress size on the market—bigger than California King, Texas King, and even the Alberta King.
Dimensions Breakdown:
- Alaskan King: 108” x 108”
- California King: 72” x 84”
- Standard King: 76” x 80”
- Wyoming King: 84” x 84”
- Texas King: 80” x 98”
- Alberta King: 96” x 96”
That translates to 81 square feet of sleeping surface. To put that in perspective—you could fit a family of four, plus a couple of dogs, and still not feel crowded.
Who Needs a Mattress This Big?
Not everyone. But for those who do—it’s life-changing.
- Families who co-sleep: No more cramped limbs or edge-of-the-bed drama
- Pet parents: Let the dogs stretch out too
- Tall sleepers: If you’re 6’6”+, this bed welcomes your feet
- Luxury-seekers: Turn your bedroom into a five-star retreat
- Light sleepers: Less motion transfer means fewer sleep disruptions
Benefits That Go Beyond Size
It’s not just about square footage. The Alaskan King offers real benefits in terms of comfort, durability, and customization.
Top Perks:
- Motion Isolation: Perfect for couples or restless sleepers
- Weight Capacity: Designed for multiple occupants and heavier frames
- Custom Comfort Options: Many models offer dual firmness zones
- Sleep Freedom: You can literally starfish without touching anyone
Bonus: It’s ideal for lounging, Netflix binges, reading with kids, or those glorious weekend sleep-ins.
Things to Consider Before You Buy
Let’s talk logistics. A bed this size requires a little planning.
Space Requirements
You’ll need a minimum room size of 16’ x 16’ to allow for walking space and furniture. Anything smaller, and it’ll feel like the bed swallowed your room.
Transportation
These mattresses are heavy. Modular models—where the mattress arrives in multiple pieces—are easier to deliver and assemble, especially if you’re working with stairs or tight hallways.
Price Tag
Expect to invest $3,500 to $6,000+ for a high-quality Alaskan King setup. Add custom sheets, a frame, and bedding, and it could run close to $7,500.
Suggested Products to Pair with an Alaskan King Mattress
An Alaskan King Mattress is more than just a bed—it’s a lifestyle center. To complete the experience, you’ll want accessories and essentials that match its scale, function, and comfort. These picks are perfect additions to elevate your oversized sleep sanctuary.
1. Oversized Comforter (120” x 120” or Larger)
A standard King-size comforter will leave you short on coverage. Look for oversized comforters labeled for “family beds” or “super king” sizes. Bonus if it’s hypoallergenic and machine-washable.
2. Bamboo or Eucalyptus Cooling Sheet Set
Alaskan Kings retain heat due to their size, especially with multiple sleepers. Cooling sheets made from breathable fibers like bamboo or eucalyptus keep things airy and comfortable.
3. Weighted Blanket for Oversized Beds
Go for a 30–35 lb weighted blanket designed for large beds. It helps reduce stress and anxiety while offering enough coverage for two or more people.
4. Bedside Shelf with USB Ports
A bed this big often means your nightstand feels far away. Clamp-on bedside shelves or floating nightstands with USB ports are ideal for holding your phone, water, or book within easy reach.
5. Sound Machine for Better Sleep
More space doesn’t always equal better sleep—especially if you’re co-sleeping with kids or pets. A white noise or ambient sound machine can block distractions and help everyone fall asleep faster.
6. Under-Bed Storage Bins (Slim Profile)
Big bed = big opportunity for hidden storage. Grab a set of rolling under-bed bins to store off-season bedding, books, or even extra pillows. Look for fabric lids or zip closures to keep dust out.
7. LED Bed Frame Lighting
Add a glow-up to your Alaskan King setup with adhesive LED light strips that run along the bed frame. Great for soft nighttime lighting, ambiance, or guiding late-night bathroom trips.
8. Adjustable Bed Tray Table
Perfect for family movie nights, breakfast in bed, or even remote work. Choose one wide enough for shared use and with foldable legs for easy storage.
9. Mattress Protector – Waterproof & Hypoallergenic
Protect your investment. Go for a protector that’s waterproof, breathable, and made specifically for Alaskan King or family-sized mattresses.
