Most people, when they are buying a new mattress, choose one of the regular-size mattresses available in Canada, and most times, these mattresses will meet your requirements. But there are times when a standard-size mattress will not do.

There are times when you might need a mattress with different dimensions. For example, to accommodate several sleepers or to fit in your RV. In this article, we focus on oversized and RV mattresses to give you an idea of what options are available in Canada outside the standard mattress sizes.

Oversized Mattresses in Canada

Oversized Mattresses in Canada

Many people are not even aware that there are several size options available that are bigger than a king-size bed. Oversized beds can be between 4 and 68 inches bigger than king-size mattresses. Because these mattresses require a larger-than-average bedroom, they are not in high demand and are only sold by a few vendors.

While oversized mattresses are more challenging to find than standard sizes, they can offer a great deal for sleepers who share a bed with a partner or who often have their children getting into bed with them. They can also provide more comfort for people who need more space either because of their size or moving around a lot during sleep.

Wyoming King

At 84 inches x 84 inches, the Wyoming king is the smallest square-shaped oversized mattress. It can comfortably fit a couple and a small child or offer extra space for two adults. The Wyoming king is the only oversized mattress that will comfortably fit in an average-sized master bedroom. The minimum room requirement is 12 feet by 12 feet.

Alberta King

The Alberta king measures 96 inches x 96 inches. It is one foot bigger than the Wyoming king and one foot smaller than the next square-shaped bed, the Alaskan king. To comfortably accommodate an Alberta king-size mattress, your bedroom should be at least 13 feet x 13 feet.

Alaskan King

The Alaskan king-size mattress, measuring 108 inches x 108 inches is the largest of the square-shaped mattresses. It is wide enough to fit more than one child with two adults and the extra-long length is great for very tall sleepers or if your pet sleeps in your bed. It is the longest of all the oversized mattresses available. You will need a minimum room size of 14 feet x 14 feet for the Alaskan king-size bed.

Texas King

Measuring 80 inches x 98 inches Texas king mattresses are slightly wider than regular king-size mattresses but considerably longer. This makes the Texas king mattress a good option for taller Canadians or those whose pet or pets sleep at the bottom of the bed. The recommended minimum room size is 12 feet x 14 feet.

Extra Wide and Super Wide King

The extra and super wide king mattresses are the same length as a standard king but considerably wider. The extra wide mattress is 108 inches and the super wide is 120 inches wide. Both sizes comfortably accommodate two adults and one child with the super king allowing more room to move about. Room size recommendations are 14 x 12 for extra wide and 15 x 12 for super wide.

Family and Family XL

Both family beds are 144 inches wide providing plenty of space for two adults and a couple of children. The family-size mattress is shorter at 80 inches, while the XL version adds four inches to the length. Both mattresses require a large room to comfortably accommodate the bed, preferably at least 17 feet wide and 12 feet long.

RV Mattresses in Canada

RV Mattresses in Canada

The other specialty mattress type we focus on in this article, are mattresses specially designed for RV use. RVs generally have less space to accommodate beds so they come in smaller sizes than standard mattresses used in our homes.

Other than bunk bed mattresses, short queen and king-size mattresses are the most common mattress sizes for RVs in Canada. Shorter than the standard queen and king-size mattresses, they are better suited for RV use.

Bunk

Bunk bed mattresses come in different sizes depending on the manufacturer. The width generally varies from 28 inches to 35 inches and the length from 75 inches to 79 inches. These mattresses are mainly used in RVs designed for family use.

RV Full

RV full mattresses are sometimes referred to as RV doubles. Full-size RV mattresses are often used in fold-out couches to optimise space. The mattress width ranges from 53 inches to 55 inches but they are generally 75 inches long.

Short Queen and RV Queen

Both queen mattress options for RVs are 60 inches wide, meaning they can comfortably accommodate two adult sleepers. The difference is in the length, with short queen mattresses measuring 74-75 inches and the RV queen 80 inches. If you are a taller person and can fit an RV queen in your camper, it is worth going for the extra length.

Short King, RV King, and RV California King

There are three king-size mattress options for RVs. They are all 72 inches wide but the lengths range from 75 inches for the short king, to 80 inches for the RV king, and 84 inches for the California king.

What to Consider When Choosing a Specialty Size Mattress?

There are several things you should think about when you are choosing an oversized mattress for your home or a mattress for your RV.

The Size of Your Space

Whether you are shopping for an oversized mattress or an RV mattress, the main point to consider is what size mattress can you comfortably accommodate. Carefully measure the space you have available and think about how easy it is to get in and out of bed and move around it.

Mattress Material

The material you choose for your mattress can make a big difference in how comfortable it feels. While RV mattresses are often made with polyfoam or memory foam, you can also choose to have a latex, hybrid, or innerspring mattress. All four options are also available for oversized mattresses.

Innerspring mattresses have more bounce than all types of foam mattresses. However, foam mattresses are better at contouring the body. For people who sleep hot, innerspring mattresses have better airflow than regular polyfoam and memory foam mattresses. Natural latex mattresses stay cooler than other foam mattresses but you can also invest in a foam mattress with cooling technologies.

Since you are likely to share oversized mattresses and probably most RV mattresses, too, consider how well the mattress isolates movement. Foam and hybrid mattresses are better at motion isolation. If you would like an innerspring mattress, pocketed coil mattresses isolate movement the best.

Preferred Sleeping Position and Weight

How firm your mattress should be depends on your preferred sleeping position and how much you weigh. People who sleep on their back or stomach should choose a firmer mattress that prevents the mid-section of the body from sinking in too low into the mattress. This will support a correct spine alignment. Side sleepers need a softer mattress that allows the hips and shoulders to sink in a little.

However, you also need to consider how much you weigh. While petite sleepers can choose a softer mattress, anyone weighing 60 kg or more needs at least a medium mattress. Taller and heavier people need a firmer surface and would benefit from choosing a mattress for heavier sleepers.

Budget

For many people, the cost of the mattress is an important factor. This especially applies to oversized beds because the costs increase with the size of the bed. While you can find good standard-size mattresses in Canada for around $500, you need to budget at least $1,500 for oversized mattresses. With family-sized beds, you are looking upward from $2,500. With oversized mattresses, you also need to factor in the cost of transport and oversized bedding.

The cost of the mattress will also depend on the material you choose. While innerspring beddings made with Bonnell or continuous coil systems are generally the cheapest, they do not offer much motion isolation. This means they are not ideal for mattresses shared by several sleepers. Hybrid, natural latex, and memory foam mattresses are often the costliest but also provide excellent motion isolation.

Transport

This factor applies more to oversized mattresses than RV mattresses. Large mattresses may not only cost you more to transport but can also be difficult to get into your home. It can be difficult to get oversized mattresses through standard-size doors and up staircases so measure your spaces carefully to ensure you can get the mattress into your home before buying.

What If You Can Not Find a Size That Meets Your Needs?

If you cannot find a mattress retailer for either oversized or RV mattresses who does the size that meets your requirements, you can get a custom-made mattress. Some manufacturers make mattresses according to the dimensions specified by you.

Look into custom-made mattresses if you, for example, need a mattress that fits an irregularly shaped space. You may also need to have your mattress custom-made if you want one in an unusual shape such as a circle or half-moon. Because the mattress is individually made, based on your specifications, the prices will be higher and the cost will increase with the size of the mattress.

Conclusion

There are several options for Canadians looking for mattresses that are either bigger than the standard sizes or fit into an RV. While most people can find a mattress that meets their needs among the selection of oversized and RV mattresses, you can also consider getting a custom-made mattress if you need one with an unusual shape or dimensions.

Before you decide on a new mattress, consider your sleeping preferences and your body weight to choose the right material and firmness level for you. It is also a good idea to research the different options available for you in Canada and read reliable reviews.
