Family on Oversized Mattress

In This Article:

We ALL know the feeling...

You climb into bed, exhausted from a long day and ready for a good night's sleep. Before long, your partner is SNORING in your ear, the kids have piled next to you, and a dog (or two) is squeezing you to the edge of your mattress.

You need more room!! Common mattress sizes are too cramped ...but unfortunately, these sizes are the only ones available at your local mattress store.

There is a solution: an oversized bed!

Oversized mattresses come in many sizes, and are much more affordable than you would think.

So how large are these bed? Keep reading to find out (hint: they are BIG)!

Oversized Bed Sizes

This is important: There is no such thing as a ‘one size fits all’ when it comes to mattresses. You have many options to consider, including custom shapes and sizes. This means that you can find the perfect bed to suit your sleep needs, meet your physical requirements, AND fit your bedroom!

Everyone is familiar with traditional mattress sizes (twin, full, queen and king).

Did you know? Oversized mattresses come in standard sizes as well! Here they are:

Alaskan King Bed

If you're going to make a mattress that is larger than all of the others, what do you name it? The Alaskan King, of course! Measuring in at a staggering 9' x 9', you'll be hardpressed to find a mattress much larger than this one.

Typical Cost - $2500 - $4000

Texas King Bed

Not to be outdone, the Texas king bed is close behind the heels of the Alaskan King, measuring 80" x 98". For many individuals, the typical 80" length on most mattresses is not enough. The Texas King is a perfect fit for those people, giving plenty of extra length for stretching out.

Typical Cost - $2000 - $3000

Wyoming King Bed

Similar to the Texas King, the Wyoming King provides a slightly longer and wider sleeping surface than your typical King. The Wyoming King measures 84" x 84", and is perfect for someone who needs a bit more room, but might be too restriced on space for something like the Alaskan King.

Typical Cost - $1500 - $2500

Keep in mind - these are standard oversized mattress sizes. We haven’t listed them all (such as the Ace), but these are the most common sizes available.

Custom Sizes Available, Too!

Most of us don’t think about getting a custom size mattress. ...but what happens when the standard sizes do not meet your needs or space requirements? No worries! Many companies can custom make mattresses in just about any size or shape! That’s not all… They can also make beds using a variety of components, including memory foam, latex, and innerspring.

Important Things to Consider

Measure Your Space

As you consider a new, large bed, you will want to make sure an oversized mattress will fit in your bedroom! You will also need to decide what, if any, foundation you’ll need.

Oversized beds need a LOT of room.

A typical Family XL King is 12 feet wide (you read that right - 12 FEET!)
When measuring your room, be sure to calculate the space required for the bed itself. Leave a bit of room on the sides so you can get out!

Have you Considered the Type of Mattress You Want?

Decisions, decisions…

My definition of ‘firm’ or ‘soft’ will probably be very different from yours. With that said, what matters most is how the bed feels to YOU.

You’ll want to be sure that whoever you buy your mattress from know how to ask the right questions and get the perfect mattress for you.

With that said, I've put together some information on mattress basics to help equip you with the knowledge to make the right decision:

Common Mattress Types

Mattresses can be CONFUSING. There are so many different types of layers, how does one keep it all straight?

This should help simplify things: Here is a list of the most common mattresses on the market (regardless of the name or layers used):

  • Memory foam mattresses: Contour to your body and relieve pressure points as you sleep
  • Gel foam mattresses: Contour to your body and relieve pressure points like memory foam, and also are designed to have a slightly cooler sleeping surface
  • Latex foam mattresses: These durable, eco-friendly mattresses aren’t temperature-sensitive. Latex, when properly made, has a uniquely supportive, buoyant feel
  • Innerspring mattresses: These traditional mattresses support heavier weights per square inch and can also help to reduce motion transfer between partners
  • Hybrid mattresses: This is a newer mattress design that takes the best in the mattresses listed above and combines them; more on Hybrid mattresses below...

Benefits of a Hybrid Mattress

First, let’s answer the obvious question: ...what is a ‘hybrid mattress?’ Hybrid mattresses are a combination of different mattress types, giving you the unique benefits of each in one bed. Hybrid mattresses come in many configurations; companies can combine memory foam with latex, or gel foam layers with innerspring.

Neat, right?

Picking a Foundation (..or going without?)

You have more foundation options than you think for your oversized mattress!

Depending on size, some oversized mattresses can fit securely on two smaller-sized foundations put together. For example - a Family King mattress can be used on two Queen-sized foundations, or a Family LX King mattress can be used with two foundations sized for a California King.

Other sizes, such as an Alaskan King, will require a custom foundation. In this case, finding a local craftsperson to make a basic platform foundation may be your best option.

NOTE - you can also choose to use your oversized mattress without a foundation! Mattresses can be placed directly on the floor and will provide the same level of support and function as one placed on a foundation!

Is an Oversized Mattress Right for Me?

This is a great question, and one worth considering before purchasing an oversized mattress. Here are some reasons why you might need an extra large mattress:

Do you need more space?

Who DOESN’T enjoy snuggling at bedtime? However, if you’re like me ...when it is time to sleep, I need my space!

Couple sharing small bed

Enter the oversized mattress - it will give you and your partner plenty of room to stretch out and get comfortable. Go ahead! Shift positions all you want, with no worries of accidentally bashing the other person (be honest, it has happened to all of us).

Family Co-Sleeping

This is beoming hugely popular; but what is it, exactly?
Co-sleeping is when babies or young children sleeping in the same bed as the parents (vs in separate rooms). There are several benefits to co-sleeping:

  • It builds helps to build bonds between parents and children
  • It allows new moms to nurse more conveniently
  • It makes it easier for parents to soothe and attend to children during the night

An oversized mattress is perfect for co-sleeping - it provides everyone the room they need for great sleep (even if your kids include a few fur babies!).

Family Sharing Bed

There are still many misconceptions about co-sleeping and family beds. Jump over to this blog post to learn more.

Extra tall individuals, and anyone looking for more room

Some of us are tall. REALLY tall. For example, the average height of a basketball player in the NBA is 6' 7"! Your standard mattress length will not cut it for these folks, and most of us don't enjoy our feet hanging off the end of the mattress.


Honestly ...who DOESN'T want more sleeping space?

Whether you’re sharing your bed with a partner, kids, pets, or even if you sleep alone - a bigger bed can be a GREAT investment for anyone who wants more space.
