(Top 5) Best Oversized Mattresses – June 2022

What are the best oversized mattresses on the market? This article will help you find out. We have researched and tested many of them, so we know which ones are worth your time. There are four that we think are great for different reasons, but there might be one that is perfect for you. Let’s get started by looking at them all in detail.

How I conducted the research

I spent 45 hours conducting this research to pick the best huge matress. I looked at 38 different mattresses, tested them, and narrowed them down to 4. I consulted with orthopaedists, dermatologists, and certified sleep consultants to add expert opinions to the subject.

What is an oversized mattress?

An oversized mattress is any mattress larger than King size mattress that measures 80 inches long and 76 inches wide. The most popular oversized mattresses are Texas king (80″ x 98″), Wyoming king (84″ x 84″), Vermont King (96″ x 96″), and Alaskan king (108″ x 108″). They are designed to fit in large bed frames, which makes them perfect for people with large space or who want something bigger than the average queen-size mattress. They are also known as “California king mattress” or ” extra large mattress”.

Here are all possible oversized mattresses sizes

California King is the smallest oversized mattress and it’s pretty close to common King size. It fits two parents with a baby or just for a couple that wants extra space at night but has a pretty small room.

Texas King mattress perfectly suits tall people and those who like sharing beds with their pets. It’s not as wide as other oversized beds, but it’s very long.

Wyoming king is a quite small oversized mattress and has a square shape. It fits three people who have too small room for an Alaskan or Alberta mattress.

Alberta King was designed for people who want Alaskan’s dimensions but has a too-small room. It is also the less popular size for mattresses. It is almost like Alaskan King, but 6″ smaller.

Alaskan King mattress has a square shape too and is designed to fit all families. This is the longest oversized mattress so it’s perfect for tall people.

Family mattress dimensions can differ depending on the manufacturer. This bed is usually 2 times the size of the standard bed, but its width is not that big. Family size mattress fits families with kids and pets.

Family XL is the biggest size on the market today. It is designed for people who like extremely big spaces while sleeping. This mattress has the size of two California King mattresses and can place at least 5 people.

Also, you can make a custom mattress if you have a specific bed, but it will be much expensive than buying a finished mattress.

Benefits of oversized mattresses

This mattress size suits people that need a lot of space for their body and sharing a bed with a partner. This mattress size also allows people with different sleeping positions to enjoy a comfortable sleep.

If you have kids that sleep in your bed – then an oversized mattress is very useful for them because they will all fit on one big bed instead of sharing a small bed with a parent.

Extra large king mattress is also good for people that share their beds with pets or partner because it allows more space to move around and not be crowded by the other person in your sleep. It is especially useful if one of you tosses and turns a lot during the night time – they won’t disturb anyone else.

Downside

The only downside of these mattresses is the big price. The larger the mattress, the more material is used in it, respectively, it will be more expensive. This should be considered before buying a large bed.

Types of oversized mattresses

Innerspring

Innerspring is the most popular type of mattress. It’s consists of steel coils that are sewn into the fabric of the mattress. The comfort layer is then added on top of this to provide a soft surface for you to rest upon.

These additional layers make it possible for these beds It’s a good choice for a lot of people because they are easy to use and inexpensive.

Foam

There are many kinds of foam. The most popular are memory, gel, and polyurethane (also called polyfoam). A gel mattress is a good option if you want to avoid foam mattresses because it doesn’t develop any smell. They are also very durable and comfortable. The only downside is that they may be too hot for some people who live in warmer climates and during the summer months – so keep this in mind when making your purchase.

Foam mattresses do not need box springs or foundations – all models available in the market are adjustable base-friendly.

Latex

Latex is one of the most durable materials in the market today. It’s also has a good airflow effect and feels almost like a foam mattress. If you have any allergies, a latex mattress is a good choice for you because it doesn’t support dust mites and other allergens.

Hybrid

A hybrid mattress combines the benefits of several types, it has innerspring construction but also contains other materials like memory foam or latex rubber. It’s a good choice if you want the durability of an innerspring mattress and the pressure relief of memory foam. But it’s also the most expensive category of mattresses.

Things to consider when choosing a mattress

When choosing a mattress, you should look at the size of your room and choose what fits best. You can also consider getting it with handles to move or transport. There are some other factors that affect the quality of your sleep.

Thickness

The perfect thickness for you depends on your weight, sleep position, medical conditions, and other factors. There are 5 types of thickness:

• low profile
• slim
• standard
• thick
• super thick

Low profile type is all mattresses to 5 inches thick. This type is very useful as a mattress topper. So if you feel like your mattress is too thin, you can add extra comfort by getting a 1-3 inches mattress topper. You can also regulate firmness level like that, just choose a mattress topper with the right firmness for you. In other cases, you don’t actually need this feature.

Slim type is 5 to 9 inches mattresses. This type is designed for children, people with limited mobility, and people who weigh less than 130 pounds. Also, it can be used as a day bed, guest bed, or trundle bed.

Standard mattress averages from 9 to 13 inches. It is also called “regular” or mid-thickness, which suits people who weigh 130 to 230 pounds. It’s the most versatile type of thickness and it has a medium-firm feel that allows for comfortability in all sleeping positions.

There are some nuances in the choice that will increase your comfort. If you are a back or stomach sleeper, you should choose a mattress that is not too thick. 9-11 inches will be perfect for you. If your spouse or child sleeps on their side, opt for one with 11-13 inches thick. It also works for combined sleepers.

The thick category features extra cushioning because it is designed for people who weigh more than 230 pounds. This type is from 13 to 17 inches mattress. While it can be soft, when you use the right firmness for your needs and weight, you will feel like sleeping on a cloud.

People who are heavier than 400 pounds should choose an extremely thick mattress. It’s also called double-thick and it has more than 17 inches thick. It has extra support in all areas of the body so if you sleep in any position you want – back, stomach, side, and combined. It’s even more comfortable with a super wide king mattress.

But you shouldn’t opt double thick mattress because it’s not suitable for most people and it can be used only for those who have obesity and other medical conditions.

Firmness

Firmness is the main factor that affects your comfort and restorable sleep. Most people fit medium firmness but there are some exceptions. The firmness level can be

• soft
• medium
• firm

If you are a light person, an orthopedic firm mattress can be uncomfortable for you. You should choose a soft type of firmness and a mattress with a big comfort layer (at least 3 inches). It also concerns children, light teenagers, and people with limited mobility. But don’t choose a mattress with a firmness level lower than 4/10. It’ll be too soft even for a child. 

If your weight is average, the medium will be perfect for you. It’s the most expanded category of firmness so you will not have trouble with finding a good mattress.

If your weight is more than 230 pounds, you should choose a firm type of mattress. It will support your body evenly. It also concerns people with back pain and spinal cord injury. But don’t overdo this measurement, 7/10 firmness level will be enough.

Some mattress manufacturers have options of firmness or even regulation built in the mattress. It’s a great benefit if you are not sure of the best firmness level for you.

Choosing the firmness of a mattress also depends on your medical conditions. Here is what orthopaedist Christopher Gilbert says about it:

“I recommended choosing a firm mattress to all people who have regular back pain and pressure in knees, hips, and chest. The ideal firmness for you is 6/10. Soft mattresses could be comfortable at the first time of use but they can cause pressure point in your spine, so you shouldn’t buy it for adults. But it still can be useful for children to 12-14 years (depends on their weight).

For other people, I always recommended a medium firmness level (4-6/10). People who have back pain or medical conditions with pressure in the knees, hips, and chest can sleep on a firmer mattress.”

Non-toxic materials

It’s especially important if you have allergies, asthma, or skin diseases like acne or eczema. Be sure that the composition of your mattress is hypoallergenic and natural. Some harmful materials like microfiber can seriously affect your skin and cause an allergic reaction. It’s concerns sheets, mattress toppers, and other bedding. In general, everything that concerns your face.

Natural cotton, linen, wool mattress covers are perfect because these materials are breathable and hypoallergenic. 

Here is what dermatologist Rosanna Conley says about it:

“Microfiber is one of the most popular materials for mattresses, especially for foam. But I don’t recommend it, because it’s synthetic and it can cause allergic reactions.

Natural fabrics are much better because this material is very tightly packed together, which makes it perfect for trapping dust mites, fungi, bacteria, and other allergens. The most comfortable and safe materials are cotton, linen, wool.”

Price

The price of the product must meet its quality standard. The price of a mattress depends on many factors such as its brand, quality, and size. You should be wary of too low a price, as the mattress most likely will not last long and could even cause health problems.

Company policy

Another important factor for mattress manufacturers is company policy. There should be a warranty for at least 2 years, convenient and fast delivery, and a free trial to evaluate and test your mattress at home.

Medical conditions

If you have a spinal cord injury, you should ask your doctor about the right mattress, because the wrong type, thickness, or firmness of the mattress can seriously affect your health. This also applies to those who have experienced major spinal surgery.

If you have regular back pain, a mattress 10-11 inches thick will relieve pain and restore your back. It’s also good for your mattress to have good pressure relief. Foam and latex mattresses usually have this all.

If you have blood circulation diseases like arthritic joints, rheumatic disease, or thrombosis in the lower extremities – you should choose a mattress that is soft with medium density.

If you are looking for a mattress for pregnancy and back pain during pregnancy, сhoose that one that is slightly softer than the usual ones (about 11-13 inches thick). It will make your body more comfortable and it will relieve pressure on the small of the back.

How I tested Casper Sleep Element Mattress

I tested the Casper Element mattress on such features:

• Durability. Based on the design and materials, we can say that the mattress will remain in good condition for at least 6 years of regular use. This is the average for foam mattresses.
• Motion isolation. In this test, Casper performed much better than the other mattresses and this is one of the reasons why it is in the first place. All movement on it is almost not felt and not heard.
• Off-gassing. Casper like other foam mattresses has a smell at the first 1-2 days after delivery. It’s a bit unpleasant but can be easily removed by ventilating the room.
• Pressure relief. It was good for all sleeper postures – back, stomach and side, because of the AirScape Polyfoam used in the top layer of Casper Element. So it’s good for people who feel the pressure on their bodies at the end of the day.
• Temperature regulation. The materials used in the comfort layer don’t retain much of the heat and that provides cool sleeping.

How does it feel to use Casper Sleep Element Mattress beyond the manufacturer’s info?

The oversized king mattress consists of two layers of breathable polyfoam so it’s a good material for people who tend to get hot and sweaty during sleep.

The manufacturer claims that the cover is breathable, but we found it also good in terms of airflow – there wasn’t any humidity build-up when sleeping on this mattress. It’s a great choice if you live in an area with high temperatures all year round or just need a cool night.

FAQ

What is the largest oversized mattress?

Many people think that Alaskan King (108″ x 108″) is the biggest mattress. But there is also Family XL, which is 144” wide and only 84” long. Some companies can make a mattress to order so you can get even more sizes.

How should I clean my mattress?

The best way to clean the mattress is by vacuuming. It protects you from dust mites, dirt, dead skin particles and it should be done once a month. But the cleaning also depends on the mattress manufacturer. For example, Casper Sleep recommends removing stains with a mild detergent and air-drying.

How often should I replace my mattress?

It depends on the durability of the materials. But, on average, it should be replaced every 8-10 years or earlier if there are visible signs of wear and tear.

The lifespan of the oversized mattress also depends on how many people sleep on it (if you have four children sleeping together, they will use up your mattress faster).

What are the different types of foam mattresses?

There are 4 most common types of foam: memory, gel, polyurethane, and latex. Memory foam is the most popular type. It is made by adding chemicals to regular foam, thus making it softer and giving it its memory effect (it returns back to its original shape). Polyfoam is the most durable material in the market today. Latex is good for allergic people and people with special medical conditions. And gel foam is suits people who are sensitive to temperature changes.

Do I need a mattress topper?

If you feel needed support and pressure relief, you don’t need it. But if your mattress is too firm to thin, a mattress topper will be a good solution to this problem. You should choose a 1-2 inch topper in this case.

Mattress pads are also a good choice because they can transform an ordinary bed into a heavenly sleeping surface. They provide extra support and comfort which is essential if you have back problems.

How many people fit in an oversized mattress?

It depends on its dimensions. If it’s Alaskan King (108″ x 108″), 4 people can be easily accommodated there. Family and Family XL can accommodate 5-7 people. And smaller sizes like Texas King, Alberta, and Wyoming can fit 2 people with a baby.

But the more the mattress is, the more comfortable each person is on it, especially if he likes to change sleeping positions at night.

What should be the room to fit an oversized mattress

Your room must have at least 12″ x 12″ dimensions. More specific measurements can be found in the table in the top paragraph of the article.

Where can I buy sheets for an oversized king bed?

Some companies include sheets and other bedding to their mattresses, but not all. In case there’s no such option, you should check Amazon or Walmart for oversized sheets.

Oversized 100% cotton sateen sheets (also called percale) will do for all types of king-sized mattresses. The sheet should be a little bit larger than the bed.

How do I know if my oversized mattress fits me?

You can try and lay on it before you purchase it, but this is not always possible. The best way to check whether it’ll fit your bedroom dimensions is by measuring the room’s length and width in inches then comparing them with recommending measurements from the table at the top of the article.

What is the biggest mattress size?

The biggest mattress size is Family XL 144” x 84”. It is also the most expensive mattress size. This size can accommodate up to 8 people comfortably. If you have a large family, this mattress size would be perfect for you. However, if you have a smaller family, this mattress size might be too big for you and your family members might not be able to sleep comfortably on it. Choose wisely!

Where can I buy a Texas king mattress?

There are a few places you can purchase a Texas king mattress. However, it is best to buy such a mattress online. I did my research and found the best Texas king mattress: #5-best-oversized-mattresses. It is made of organic materials and will give you the best sleeping experience.
