What Sizes Can a Custom Mattress Come In?
Sometimes, investing in a custom sized mattress is a necessity. Maybe you have a unique bed frame that’s a family heirloom, need a special mattress for your RV, or simply want a super big bed.
You can get a custom size mattress in really any size or shape you want—just remember, the more outlandish the mattress, the higher the price tag. However, it is easier to describe what you want if you know more about some of the more common custom mattress sizes.
This article goes over a few reasons to get a custom mattress and the most common custom mattress sizes.
Popular Custom Mattress Sizes
This means anyone with an antique bed frame, headboard, or footboard may need to order a custom sized mattress because none of the standard sizes fit. Shoppers also buy custom beds because they want something extra big. In the 1960s and 1970s, colossal custom mattresses like the Texas and Alaskan king became popular.
King and queen size mattresses didn’t become popular in the US until the 1950s. As the king and queen mattresses became more popular, mattress companies decided to make wider or longer versions of the standard mattress sizes. Here are some of the most common custom mattresses:
A super single mattress is 48 inches wide and 84 inches long. Compared to a standard single (or twin), which is 38 inches wide and 75 inches long, the super single is significantly larger.
As far as custom beds go, the super single is a more affordable price because it isn’t substantial. This custom mattress is excellent for single sleepers who are tall and want to be able to spread out.
Olympic queen mattresses are 66 inches wide and 80 inches long. They are the same length as a standard queen but with an extra 6 inches of width. This is great for partners who want a little extra room for themselves at night.
One of the biggest bed sizes is the Texas King. The Texas King is 80 inches wide and 98 inches long. Compared to a standard king mattress, which is 76 inches wide and 80 inches long, the Texas king is massive. Tall couples who want plenty of room are well suited to this mattress size.
At 108 inches by 108 inches, the Alaskan king is a staggering 32 inches wider and 28 inches longer than a standard king mattress. Partners who enjoy plenty of room to themselves are a good fit for this type of mattress.
To fit this mattress comfortably, you need a bedroom that is at least 16 feet by 16 feet. Otherwise, your room will feel cramped.
Reasons to Get A Custom Mattress
Many people order custom mattresses because they want something longer or broader than a standard size mattress. Others need a custom mattress because they have unique space to fill. Yet more people need a mattress tailored to their sleep needs.
Let’s take a closer look at a few common examples of this:
While many RVs include mattresses for their built-in beds, these mattresses are usually made of thin foam that doesn’t accommodate all of your sleep needs. If you suffer from lower back pain, consider ordering a medium-firm innerspring replacement mattress that both supports and conforms to your body.
The best RV mattresses can help your body rest in a neutral position (which keeps your neck, spine, and hips aligned), giving you a deep night’s sleep. A great way to make the most of your RV experience is buying a custom mattress that fits the bed frame perfectly and keeps you well-rested.
For the avid camper, a custom mattress that can fit in the bed of a truck makes traveling the country much more accessible. Make sure your custom dimensions are accurate so your bed is a perfect fit. Also, be sure to order a truck bed mattress that is well suited to your sleep style.
- A medium-firm to firm mattress for back sleepers helps them rest in a neutral position.
- Side sleepers rest well on a medium mattress, although some prefer a plusher mattress for side sleeping because the extra softness helps keep pressure off their shoulder and hip joints.
- Stomach sleepers need a firm mattress to keep their neck, spine, and hips aligned.
Ordering custom mattresses for a boat is relatively common. Boats often don’t have beds built-in, meaning you have to install them yourself then order a mattress that fits snugly in the new frame.
Your bed frame sometimes has to be a unique shape to easily fit inside the cabin of your boat, so measure carefully to ensure you know the exact size before ordering your custom mattress.
Keep in mind that a box spring isn’t practical on open waters (in rough weather, it could slide off-center). Design your bed so it is a comfortable height for you with just the frame and the mattress.
You should also keep in mind your sleep needs when ordering a custom bed. For example, a hybrid mattress with high-density foam and at least 800 coils offers plenty of healthy support for back and side sleepers.
Custom Sheets and Duvets
If you purchase a custom mattress, you need custom bed accessories to fit your unique bed. Confirm the mattress dimensions with the manufacturer making your bed and use these to order custom-made:
If you don’t already have a bed frame, you need to also use the mattress dimensions to find or commission a bed frame to complete your custom bed.
Someone may order a customizable mattress because they want a bed made of eco-friendly materials, like organic cotton, natural latex, and recycled coils. These materials decrease the number of harmful chemicals inside the mattress and tend to be more antibacterial than standard mattresses.
We must stress that there is a difference between organic and natural mattresses, as organic is a more heavily regulated term. Essentially, organic means the materials passed a higher standard of production, but this means an increased cost.
Can I cut a mattress to size?
While it is possible to cut through the materials of a mattress, we don’t advise cutting your mattress. Inside there are several layers of foam, latex, and coils. And it’s nearly impossible to cut evenly through them all. Also, sealing the mattress back up in a way that keeps it from sagging on the cut side is very challenging.
Lastly, cutting up your mattress would void its warranty. This lack of protection will leave you with no defense to easily replace your mattress. It’s best to simply purchase a new mattress that is the size you need.
Do two twin mattresses make a king mattress?
Two twin mattresses (each 38 inches wide and 75 inches long) don’t equal a king sized bed (76 inches wide and 80 inches long). However, at 38 inches wide and 80 inches long, two twin XL mattresses are the same dimensions as a king sized bed.
Setting two twin XLs side by side is how a split king bed is created. Thanks to having two mattresses, a split king size mattress allows you and your partner to adjust your own side of the bed however you please.
Are there any beds that are bigger than a California King?
The Alaskan and Texas king mattresses are both bigger than a California King bed. A Cal king is 72 inches wide and 84 inches long, a Texas king is 80 inches wide and 98 inches long, and an Alaskan king is 108 inches wide and 108 inches long.
What is the biggest mattress in the world?
The biggest mattress in the world is the Alaskan king. At 108 inches by 108 inches, there is no shortage of room on this bed. The Alaskan king was most likely first produced in the 1960s-70s. Around this time, the California king was trendy. With more people interested in large mattresses, manufacturers started making beds bigger and bigger.
Does an RV require a custom mattress size?
Some RVs may require custom mattresses. RVs have various bed sizes, depending on whether it’s designed for a family or one couple. If it sleeps multiple people, it probably has RV bunk mattresses, which range from 28 inches wide and 75 inches long to 35 inches wide and 78 inches long. If the RV sleeps only one couple, it may have a short king (72 inches by 75 inches) or a short queen (60 inches by 75 inches), both smaller than their standard sizes.
Most RVs come with mattresses that fit each bed, but they are usually made of 5-6 inches of foam and not very comfortable. To get your best sleep while traveling, you should consider ordering a custom mattress that fits your RV bed and suits your sleep needs.
Should You Invest in a Custom Sized Mattress?
There are two main reasons to buy a custom mattress:
- You have an oddly shaped bed frame
- You just want a big bed
Both are good reasons to order a custom mattress.
We each have unique sleep needs and preferences. If a custom mattress gives you the comfort and support you need to get a good night’s sleep, that’s an excellent reason to invest in one. Complete your custom mattress with custom bed accessories and enjoy!
