Pros and Cons of Alaskan King Mattresses

Given its grandeur, an Alaskan king bed is a luxurious choice. However, there are a few drawbacks to consider before purchasing a mattress this massive. Anyone interested in an Alaskan king should weigh these pros and cons to make an informed decision about a mattress size upgrade.

Pros

  • Personal Space: An Alaskan king bed affords maximum sleep space. You’ll have plenty of room to sprawl out, get comfortable, and enjoy unrestricted rest.

  • Minimizes Sleep Interruptions: Alaskan kings make bed-sharing easy. With room to spread out, your partner’s movements won’t disrupt your REM.

  • Room for Co-Sleeping: Need a family bed suited for co-sleeping with children or pets? Alaskan kings fit the bill, offering ample space for parents, young kids, and beloved pets to share a bed for connection and comfort.

  • Luxury Look and Feel: An Alaskan king bed automatically elevates your bedroom aesthetic. It’s also the perfect canvas for decorating with a stylish bed frame, bedding textures, and a creative pillow stack.

Cons

  • Price: By nature, bigger beds cost more. When considering the costs, remember that you’ll also need an Alaskan king size bed frame and bedding for your new mattress.

  • Large Bedroom Required: Alaskan king beds take up considerable space. Grab a measuring tape to assess your bedroom’s size and how a 9-foot-by-9-foot bed would fit with your other furniture and walkways.

  • Difficult to Move: Once you set up your Alaskan king mattress and base, they are challenging to relocate due to their size and weight. Moving your bed will require some logistical planning and heavy lifting.

What You Need to Know Before Buying an Alaskan King Bed

We understand that an Alaskan king sleep setup is a big investment. Before adding a giant mattress to your online cart, carefully consider each factor below.

Required Room Size

If you’re interested in an Alaskan king bed, you first need to determine if you have enough room. To comfortably accommodate the bed, additional bedroom furniture, and walkways, you’ll need about 15 feet by 15 feet of space or more.

Occupancy

How do you plan to use your oversized mattress? Alaskan kings make the ideal family bed for co-sleepers and pet owners. Two adults plus three to four children or pets can all fit on this giant bed.

Mattress Construction

Oversized mattresses may not be as common as the standard twin through California king sizes, but you’ll still have a handful of brands of models to choose from. To find your ideal fit, look closely at each model’s materials, layer count, firmness feel, and additional features while comparing your options.

Mattress Types and Materials

Our Mattress Material Guide unpacks the most popular mattress types on the market: foam, latex, hybrids, and innerspring. When it comes to Alaskan king size mattresses, we strongly recommend hybrid builds for optimal comfort, support, and durability. Hybrid mattresses combine a coil core with foam upper layers to provide structural strength and pressure relief, which is exactly what you need for a long-lasting Alaskan king bed.

Firmness Level

Regardless of the mattress size you choose, identifying the ideal firmness level for your sleep position, weight, and contouring preferences is essential for finding a comfortable fit that properly supports your spine. Head over to our Mattress Firmness Guide for help deciding between a plush mattress, a firm mattress, or something in the middle.

Additional Features to Compare or Consider

You’ll receive easy-to-follow instructions and the following pieces: four mattress cores, one foam attachment, and one mattress shell. You’ll need two people to set up the mattress, but it’s quick and easy. Your bed will be sleep-ready after you let it expand for a few hours.

Alaskan King Bed Frames, Bedding, and Accessories

Don’t forget! If you’re changing mattress sizes, you’ll need a new foundation. Look for a base specifically made for an Alaskan king size mattress (108 inches wide by 108 inches long). We recommend a platform or slatted base design for maximum durability.


You’ll also need Alaskan king size bedding, like a sheet set and comforter or duvet. A mattress protector isn’t required but will go a long way to keep your mattress clean and safe.

Conclusion

With their staggering dimensions, Alaskan king beds redefine sleep luxury and personal space. For mattress shoppers with the bedroom space and budget, Alaskan kings offer uncompromising comfort that couples, parents, kids, and pets can all enjoy.
