I’ve been researching oversized mattresses, and the Alaskan King keeps coming up as the ultimate solution for families who need serious space.
If you’ve ever wondered just how big these giants really are, you’re in the right place. An Alaskan King measures nine feet by nine feet; absolutely massive compared to anything you’ll find in a typical mattress showroom.
In this post, I’ll walk you through the exact dimensions, show you how it stacks up against standard sizes, and cover the challenge of finding bedding that actually fits.
I’ll also help you figure out if your bedroom can handle it and share some practical buying tips.
How Does an Alaskan King Bed Compare to Standard Beds?
When I first saw the numbers, I couldn’t believe the difference. An Alaskan King isn’t just slightly bigger; it’s in a completely different league. To put this in perspective, it’s over two feet longer and wider than a standard King.
Here’s how it stacks up against the beds you’re probably more familiar with:
| Mattress Size | Dimensions | Total Area | Fits Comfortably |
|---|---|---|---|
| Standard King | 76″ × 80″ | 6,080 sq in | 2 adults + 1 pet |
| California King | 72″ × 84″ | 6,048 sq in | 2 adults + 1 pet |
| Alaskan King | 108″ × 108″ | 11,664 sq in | 4+ adults or 2 adults + 3–4 kids/pets |
The Alaskan King offers nearly twice the sleeping area of a standard King. That’s enough room for multiple adults, several children, or a small army of pets, all without anyone fighting for space.
Who is an Alaskan King Best for?
Not everyone needs a mattress this size, but for certain situations, an Alaskan King is a game-changer.
Here’s who benefits most from all that extra space:
- Large Families Who Co-Sleep: Parents with multiple young children can finally fit everyone comfortably without someone getting kicked off the edge.
- Couples Who Love Personal Space: If you or your partner sprawls out or needs distance to sleep well, this eliminates the battle for territory.
- Tall Sleepers: At nine feet in every direction, even the tallest people can stretch out diagonally without their feet hanging off.
- Pet Owners With Big Dogs: Your Great Dane or multiple furry friends can claim their spot without crowding you out of bed.
- Luxury Vacation Rentals: Airbnb hosts and boutique hotels use these as a unique selling point that guests remember and rave about.
If any of these scenarios sound familiar, an Alaskan King might be worth the investment. It’s not just about having more room; it’s about converting how your whole household sleeps.
Room & Layout Planning: Will an Alaskan King Fit?
Before you fall in love with the idea of an Alaskan King, you need to make sure it’ll actually fit in your space. This isn’t just about the bedroom; getting it through your home is half the battle.
1. Minimum Bedroom Size and Clearance
Your bedroom should be at least 14 ft × 14 ft (168 in × 168 in) to accommodate the mattress with walking space around it. Ideally, leave 2 to 3 feet of clearance on each side for easy movement and making the bed.
Don’t forget to measure doorways, hallways, and staircases. Most standard doors are only 36 inches wide, which creates a major obstacle for delivery.
2. Measuring Your Room and Planning Placement
Grab a tape measure and map out your bedroom dimensions on paper first. Mark where windows, closets, and outlets are located, then sketch in the 9 ft × 9 ft footprint.
This helps you visualize traffic flow and ensures you’re not blocking access to essential areas. Consider centering the bed or placing it against your longest wall for the best layout.
3. Moving and Delivery Constraints
Getting an Alaskan King into your home is often impossible as one piece. Many manufacturers offer split mattresses (two sections that zip together), making delivery and maneuvering through tight spaces much easier.
If you move frequently or have narrow hallways, a split design isn’t just convenient; it’s essential for actually getting your mattress where it needs to go.
Frames, Foundations & Bedding for Alaskan King
Finding the right setup for an Alaskan King takes some extra effort since you won’t find these accessories at your local home goods store.
Here’s what you need to know about frames and bedding:
| Category | Type | Construction/Material | Key Benefits |
|---|---|---|---|
| Frames | Custom-built platform | Sturdy wood or metal | Built to exact 108″ × 108″ specs for a perfect fit |
| Modular frames | Adjustable metal frames | Expands to fit oversized dimensions | |
| Foundations | Two-piece split box springs | Standard box spring material | Easiest to maneuver through doorways |
| Platform base | Solid wood slats | No box spring needed; provides firm support | |
| Bedding | Custom sheets | Cotton, linen, microfiber | Fitted sheets made to 108″ × 108″ dimensions |
| Mattress protectors | Waterproof fabric | Available through specialty retailers | |
| Comforters & duvets | Down, down-alternative | Minimum 120″ × 120″ for proper overhang |
Many Alaskan King mattress companies sell matching bedding bundles, which saves you the headache of hunting down compatible sheets and protectors separately.
Mattress Types Available for the Alaskan King Bed
Just because you’re buying an oversized mattress doesn’t mean you’re limited in construction options. Alaskan Kings come in the same varieties as standard mattresses, each with its own advantages.
Common Mattress Constructions
Alaskan Kings are available in all the major mattress types you’d find in standard sizes. Here’s how each construction holds up at this scale:
- Foam: Memory foam and polyfoam offer excellent pressure relief and motion isolation, perfect for multiple sleepers. However, they can trap heat and may sag faster under heavy weight at this size.
- Hybrid: Combines foam comfort layers with innerspring coils for the best of both worlds. Breathable, supportive, and durable, making it ideal for large mattresses that need longevity.
- Innerspring: Traditional coil mattresses provide strong support and excellent airflow at a lower price point. Motion transfer can be an issue with multiple sleepers or pets.
- Latex: Natural or synthetic latex offers superior durability, bounce, and cooling. The most eco-friendly option that resists sagging, but comes with a premium price tag at Alaskan King dimensions.
Custom vs. Manufacturer-Made Options
Manufacturer-made Alaskan Kings from established brands typically range from $2,000 to $6,000 and ship within 4 to 8 weeks.
Custom orders from local mattress makers or specialty shops offer more personalization in firmness, materials, and split configurations, but expect to pay $5,000 to $10,000 with lead times of 8 to 12 weeks or longer.
What You’ll Pay: Logistics & Costs Breakdown
Budgeting for an Alaskan King goes beyond the mattress price tag. Here’s a complete breakdown of what you need to factor in:
| Cost Category | Price Range | What’s Included | Return/Warranty Policy |
|---|---|---|---|
| Mattress | $2,000 to $10,000+ | Manufacturer-made or custom-built; varies by construction type | 10 to 25-year warranty; many are final sale |
| Shipping | $200 to $800 | Oversized freight shipping | White glove delivery and setup cost extra |
| Frame/Foundation | $500 to $3,000 | Platform frames or split box springs; wood or metal construction | Varies by manufacturer |
| Bedding | $300 to $800 | Custom sheets, protector, oversized comforter | Bundle packages available |
| Setup & Installation | $100 to $300 | Professional assembly | Often included with delivery packages |
Most people budget only for the mattress and get sticker shock when accessories and delivery add another $1,500 to $3,000. Plan for the full cost upfront so you’re not scrambling to cover extras later.
Alaskan King Pros and Cons: Is It Worth It?
An Alaskan King solves real problems for certain households, but it also comes with challenges you won’t face with standard sizes.
The Upsides of Going Giant
For families and sleepers who need serious space, the benefits are hard to ignore:
- Unmatched sleeping space: Everyone gets room to spread out without disturbing each other, whether it’s multiple kids, pets, or restless sleepers.
- No more bed battles: Couples finally have enough territory that no one wakes up clinging to the edge or fighting over blankets.
- Perfect for co-sleeping families: Parents can comfortably sleep with young children without worrying about someone rolling off or getting squished.
- Luxury experience: The sheer size creates a hotel-suite feel, making your bedroom a true retreat.
The Drawbacks You’ll Face
Before you order, understand these limitations aren’t minor inconveniences:
- Significant upfront investment: Between the mattress, custom bedding, and foundation, you’re looking at a total of $3,000 to $15,000.
- Limited availability: You can’t walk into a store and buy one; most require custom orders with lead times of weeks or months.
- Delivery and setup challenges: Getting it into your home often requires split mattresses, professional movers, and sometimes even removing door frames.
- Space requirements: You need a large bedroom with wide doorways and hallways, which rules out most apartments and smaller homes.
The decision ultimately comes down to whether the benefits of the space outweigh the logistical headaches and costs. If you have the room and budget, an Alaskan King can genuinely improve your family’s sleep.
Alternatives to Alaskan King
If an Alaskan King feels like overkill or won’t fit your space, consider these other oversized options.
- A Wyoming King (84″ × 84″) offers serious room without the full nine-foot commitment.
- The Texas King (80″ × 98″) works better for tall sleepers who need length over width.
- A Family XL (144″ × 84″) provides more horizontal space if your room is wide but not deep.
You can also create a split custom king setup by pushing two Twin XL or Full mattresses together, giving you flexibility with separate firmness levels and easier delivery through tight spaces.
The Bottom Line
After digging into everything an Alaskan King has to offer, I can see why it’s become the go-to solution for families who refuse to compromise on sleep space.
Yes, the logistics are complicated, and the cost adds up quickly, but if you’ve got the room and budget, few things beat waking up without someone’s elbow in your face.
For co-sleeping families with kids, pet owners who share their bed, or anyone craving that five-star hotel feeling at home, this mattress delivers.
