What Should I Consider When Buying a New Bed?

The table above gives you some basic facts about King and Queen-sized beds. Now, let’s delve deeper into the details.


Prices for King and Queen-size beds vary by brand and quality. Because King beds are larger, they are usually more expensive than Queen beds. The accessories for a King bed will also be more expensive for this reason. 

Queen and King beds are both popular and widely available, which means that finding accessories for them will not be difficult. The price difference between King and Queen beds is usually not a dealbreaker for customers, but keep in mind that the larger the mattress, the higher the price. 

Worried that your larger mattress might not live up to the higher price point? The SONU Sleep System includes a 100-day trial period and a 5-year warranty to ensure your new bed brings you the sleep of your dreams. 

Bedroom Size

King beds are 16 inches wider than Queen beds, so they need to be placed in larger rooms. A 10’ by 14’ room should be big enough for a King bed — the master bedroom in your home may be just the right size.

Because the Queen bed is more narrow, you have more options for where you can put it. It will fit nicely in rooms that are 10 feet by 12 feet. This gives you plenty of options, from the master bedroom to a smaller guest bedroom.

Before purchasing a mattress, measure your bedroom to confirm that the bed you want will fit alongside your other furniture. 

Do you plan on putting a dresser in your room? How about side tables, lamps, a bench, or a chair? Your ideal bedroom should fit all of the items you wish to decorate it with and still leave space so that you can move around freely. 

Sleeping Partners

If someone sleeps beside you at night, be that a partner, your children, or your pets, you need to consider how much room your bed will provide you. A King-size bed is usually enough to accommodate a few people — for example, a couple and their children may be able to share a King bed. Your pets might even be able to sleep at your feet.

A Queen bed will be enough if you sleep alone, but another person could still sleep beside you. You will each have a space that is 30 inches wide and 80 inches long.

If you sleep with a partner, are you easily awakened by one another’s movements? Do you have different sleep schedules? 

Motion transfer can often wake people up if their sleeping partners move throughout the night — that’s why the SONU Sleep System features a plush layer of serene foam. 

If your partner’s movement doesn’t bother you and you prefer to sleep together snugly, maybe you should buy a Queen bed. If your partner’s movements easily perturb you, think about getting a King bed. The further apart you are, the less likely you are to feel the other person’s movement. 

If one of you prefers to read in bed late at night while the other is sleeping, consider a split King bed with an adjustable base. That way, the person reading can raise their side of the bed up while the other person sleeps soundly. 

Your Height

Height is another factor to consider when choosing a bed. This is where King and Queen beds are equally accommodating — both beds are 80 inches long. This means that any person 6 feet 7 inches tall or shorter will be able to sleep without their feet hanging off the end of the mattress. Anyone taller than that might want to consider a California King bed.

Your Size and Sleep Position

You should also consider your size and your partner's size when choosing a bed. 

If you’re a physically larger single sleeper, a Queen bed will be a good option for you. If you and your partner are larger, a King bed will be better. 

If you are tall and need more legroom, a King bed or California King may be enough. A Queen bed is a good choice if you are of shorter stature.

Your choice of bed could depend on your sleep position, too. Side sleepers tend to take up less space on a bed, so a Queen bed providing you with 30 inches of width per person may be enough. Back and stomach sleepers take up more space, so having 38 inches per person would be a better choice. Of course, if you sleep alone, either option may work for you.


King and Queen beds can be a challenge during the moving process. Considering that the King bed is 16 inches larger, you may have more trouble moving it into your home. A Queen bed may be easier to transport on the back of a truck and carry upstairs. However, if you’re using professional movers to put your bed into your home, neither bed will be an issue to move in.

What Are the Different Types of King and Queen Beds?

King and Queen mattresses come in a few size variations to suit the preferences of many customers. Some you may have heard of, while others may be completely new to you. Keep reading to learn more about these revolutionary mattresses.

Queen Mattresses

Queen RV Mattress

A Queen recreational vehicle (RV) mattress, as the name implies, is made for RVs. It is 60 inches wide by 75 inches long, maKing it five inches shorter than a regular Queen bed. Usually, when RV owners want a mattress to accommodate two people, they get a full bed. The Queen RV mattress is harder to come by.

Split-Queen Mattress

A split Queen mattress is made of two mattresses that measure up exactly to a standard Queen bed when placed side by side. Having two mattresses allows buyers to select two different types of firmness. Like the Queen RV mattress, a split Queen mattress is a little hard to find.

Olympic Queen Mattress

An Olympic Queen is a mattress size between a Queen and King size. It’s 66 inches wide by 80 inches long. The Olympic Queen is rare, maKing it hard to find appropriate bedding and frames. Because it’s a rare mattress, it can be expensive to purchase.

King Mattresses

California King Mattress

California King mattresses are 72 inches wide by 84 inches long. The bed is great for anyone taller than average. Their feet won’t dangle from the side of the mattress like they might from a King mattress. The California King is narrower than a standard King mattress.

Texas King Mattress

This oversized mattress is 80 inches wide by 98 inches long. This mattress is another great option for people who are taller than average. It’s also perfect for multiple sleepers. A family and their pets can all sleep comfortably together.

Alaskan King Mattress

The Alaskan King bed is the largest mattress available. This behemoth is 108 inches wide by 108 inches long. It can fit in a bedroom that’s 16 feet by 16 feet or bigger if you can manage to move it.

Wyoming King Mattress

Never heard of this one? You’re not the only one. The Wyoming King bed is 84 inches wide by 84 inches long. It’s not easy to find, but if you do find it and buy it, you’ll probably want to make sure your bedroom is at least 14 feet by 16 feet or larger.

King RV Mattress

Just like the Queen RV mattresses, King RV mattresses are made specially for RVs. It’s the biggest bed that you can put into a vehicle.

Although the King RV mattress’s measurements may vary, it is typically 72 inches wide by 80 inches long. 

Split-King Mattress

Split-King mattresses are made up of two Twin XL mattresses. Like the split-Queen mattress, the separate sides of the split-King can come in different firmness levels. It’s helpful to use adjustable bases so the mattresses can be adjusted to different heights if two sleepers want their sides of the bed to be at different levels.

What Are the Types of Mattresses?

The material beds are made of is more important than what size you choose to sleep on. There are plenty of mattress types that suit different types of sleepers. The most common are foam mattresses, spring mattresses, and hybrid mattresses.

Spring mattresses have coils in their support core, creating a flexible mattress. This type of mattress has been around longer than foam and hybrid. 

Foam mattresses have support cores made of specific types of foam, like memory foam or serene foam. They are best for motion transfer. 

Hybrid mattresses are usually made of two mattress types, like foam and coils. The combination of two materials makes the mattresses both comfortable and stable.


Sleeping on a King or Queen-size bed is a luxury for many people. If you stick to the standard sizes, you’ll have no trouble finding frames and bedding for either mattress. The key to finding the perfect mattress is looKing for quality. 

At SONU, we know a thing or two about quality mattresses. The SONU Sleep System comes in a range of sizes, from Twin XL to California King. Your new mattress from SONU features a Comfort Channel, four Support Pillows, sink-in support, and a plush layer of serene foam for optimal comfort. 

With SONU, you can rest assured that you have chosen a mattress that will bring you a luxurious sleep experience. You deserve it!


How big are standard King and Queen beds?

Standard King-size mattresses are 76 inches wide by 80 inches long. Standard Queen mattresses are 60 inches wide by 80 inches long.

Can King and Queen beds use the same bedding?

No, King and Queen beds cannot share bedding. The King-size bed is 16 inches wider than a Queen bed.

Are there mattresses bigger than the King bed?

Yes! Many specialty mattresses are larger than a King bed, such as the California, Texas, Wyoming, and Alaska King-size beds. These sizes are very rare, so it will be hard to shop for them but not impossible.

What bed is best for side sleepers?

Most beds can accommodate side sleepers. However, between the King and Queen mattresses, side sleepers, who do not take up much space while sleeping, may not need more than a Queen bed. 

One of the biggest issues side sleepers face, however, is uncomfortable pressure on the arm and shoulder they sleep on. That’s why the SONU Sleep System features a patented Comfort Channel that allows you to immerse your arm and shoulder into the mattress. With SONU, even side sleepers can enjoy an unforgettable sleeping experience.
