What’s The Biggest Mattress You Can Buy

If you’re looking for a truly massive bed, you might be wondering what’s the biggest mattress you can buy. The answer takes us into the world of specialty and custom bedding, far beyond standard retail sizes.

For most people, a king or California king is plenty large. But sometimes, you need more. Maybe you have a huge bedroom, a family that piles in for movies, or you just love having tons of space to sprawl out. The biggest standard mattress size widely available is the Alaskan King. However, you can go even bigger if you’re willing to order something custom-made.

Let’s break down the dimensions, where to find them, and what you need to consider before buying a giant bed.

What’s The Biggest Mattress You Can Buy

The title for the biggest standard mattress you can buy goes to the Alaskan King. It’s a true behemoth. But it’s crucial to understand that “standard” here is relative. You won’t find these at every mattress store.

Here are the common giant mattress sizes, from large to colossal:

  • Wyoming King: Often the first step beyond a standard King. It measures 84 inches wide by 84 inches long (7′ x 7′). It’s a perfect square, offering significant extra width and a bit more length than a standard king.
  • Alaskan King: This is the widely recognized giant. It measures 108 inches wide by 108 inches long (9′ x 9′). It’s essentially a square that can comfortably sleep four adults.
  • Texas King: This one takes a different approach. It’s extra long rather than a perfect square. Dimensions are 80 inches wide by 98 inches long (6’8″ x 8’2′). It’s ideal for very tall individuals who fine the California king still too short.

Beyond these, you enter the realm of custom sizes. With a custom order, your mattress is only limited by your room size, budget, and the manufacturer’s capabilities. We’re talking 10×10 feet, 12×12 feet, or even larger. These are often found in luxury estates, upscale hotels, or specialty settings.

Understanding Dimensions and Square Footage

It’s helpful to visualize how much space these mattresses actually consume. Compare them to a standard King (76″ x 80″):

  • A Wyoming King adds 8 inches in width and a full 4 inches in length. That’s over 10 extra square feet of sleeping surface.
  • An Alaskan King adds a staggering 32 inches in both directions. It provides nearly double the square footage of a standard King mattress.
  • A Texas King is actually narrower than a standard King but adds 18 inches in length, making it the best choice purely for height.

Before you get excited, you must measure your room. Remember to leave at least two to three feet of walking space on at least two sides of the bed. An Alaskan King in a standard 12×12 foot room would leave very little room for anything else.

Where to Buy Giant Mattresses

You won’t find these at your typical big-box retailer. Here’s where to look:

  • Specialty Online Retailers: Several companies specialize in oversized mattresses. They usually make them to order and ship them directly to you compressed in a box.
  • Custom Mattress Makers: Local or national custom mattress manufacturers can build any size you request. This is your only option for sizes beyond the Alaskan King.
  • High-End Furniture Stores: Some luxury furniture or bedding stores may carry or be able to order Wyoming or Alaskan king sizes.

When shopping online, read reviews carefully. Check their policy on returns and warranties, as shipping a mattress this size back can be a logistical nightmare.

Key Considerations for Bed Frames and Foundations

Your giant mattress needs proper support. A standard bed frame won’t work.

  1. Custom Frame: You will almost certainly need a custom-made bed frame or platform. Many mattress retailers offer these as part of a bundle.
  2. Reinforced Support: Ensure the frame has a sufficient number of center support legs (often 6 or more) to prevent sagging in the middle. The slats should be no more than 2-3 inches apart.
  3. Room Access: Consider how you’ll get the frame into the bedroom. Some companies design frames that assemble (and disassemble) easily in the room.

The Challenge of Bedding

Finding sheets, blankets, and mattress protectors for an Alaskan or Wyoming King is a whole other task. Standard bedding sets won’t fit.

  • Specialty Retailers: The same companies that sell the mattresses usually sell the corresponding bedding. Your selection will be more limited and often more expensive.
  • Custom Bedding: For custom sizes or if you want specific materials, you may need to have bedding made. This is a common service offered by seamstresses or online custom fabric shops.
  • Mattress Pads/Protectors: Don’t forget these! Protecting such a large investment is crucial. Order the protector at the same time as your mattress.

Pros and Cons of a Giant Mattress

Is a mattress this big right for you? Let’s weigh the advantages and the drawbacks.

Advantages

  • Unmatched Space: The obvious pro is space. You’ll never fight for covers or feel crowded. It’s excellent for couples with children or pets who join them.
  • Ideal for Tall Sleepers: The Texas King and Alaskan King offer exceptional length for people over 6’5″.
  • Luxury Statement: A massive bed becomes the stunning centerpiece of a master suite.
  • Great for Mobility: If you have mobility issues, a lower, wider bed can be easier to get in and out of from any side.

Disadvantages and Challenges

  • Cost: Everything is more expensive—the mattress, the custom frame, the bedding, and even moving it.
  • Limited Selection: You’ll have far fewer models, materials, and firmness levels to choose from compared to standard sizes.
  • Delivery & Setup: Getting it into your home can be difficult. It may not fit up stairwells or around tight corners. Professional delivery and setup is highly recommended, and sometimes required.
  • Difficult to Move: If you move homes, transporting the mattress is a major undertaking. Some custom sizes may not fit through standard doors.
  • Room Dominance: It will dominate your bedroom, leaving less space for other furniture.

Step-by-Step Guide to Purchasing a Giant Mattress

If you’ve decided to go big, follow these steps to make the process smoother.

  1. Measure Your Room Precisely: Measure the room’s length and width. Mark out the mattress dimensions on the floor with tape to visualize the space left for nightstands, dressers, and walking.
  2. Check Access Points: Measure hallways, stairwells, and doorways from the street all the way to your bedroom. Account for tight turns.
  3. Set a Budget: Include the mattress, frame, foundation, bedding, and delivery/installation costs. Prices can very widely.
  4. Research Retailers: Look for companies with strong reputations for quality and customer service in the oversized mattress niche. Read independent reviews.
  5. Order Samples: Most online retailers offer fabric and foam sample kits. This is crucial since you can’t test the mattress in a store.
  6. Confirm All Details Before Buying: Double-check the exact dimensions, return policy, warranty, and delivery timeline. Ask about the return process—who pays for pickup if you don’t like it?
  7. Order Bedding Simultaneously: Don’t wait until the mattress arrives to order sheets. You’ll want them ready.
  8. Prepare the Room: Clear the path and the room before delivery day. Have help available if the delivery crew needs it.

Custom vs. Standard Giant Sizes

Should you choose a standard “giant” size like an Alaskan King or go fully custom?

Choose a Standard Giant Size (Wyoming, Alaskan, Texas King) if:

  • You want the relative ease of finding bedding from a few dedicated suppliers.
  • You might move someday and hope the next homeowner might appreciate the size.
  • You’re comfortable with the dimensions as they are.

Choose a Fully Custom Size if:

  • Your room has an unusual shape or you want a specific, non-standard dimension.
  • You are creating a built-in platform bed and need a precise fit.
  • Standard giant sizes are still not big enough for your vision.

Caring for Your Massive Mattress

A mattress this size and cost deserves proper care to ensure it lasts for years.

  • Use a Mattress Protector: This is non-negotiable. It guards against spills, stains, dust mites, and allergens.
  • Rotate Regularly: Even if it’s a no-flip design, rotate it head-to-foot every 3-6 months to ensure even wear. This is a two-person (or more) job.
  • Ensure Proper Support: Regularly check the bed frame and center supports for any signs of bending or weakness.
  • Clean with Care: Vacuum the surface occasionally with an upholstery attachment. For spots, use a mild detergent and cold water, and blot gently. Avoid soaking the mattress.
