Split king beds are becoming increasingly popular, and this trend is expected to continue. It has a king-sized bed’s proportions, but it uses two mattresses, giving you additional customisation and mobility options. However, if they always go apart, the gap can be a bit of a pain.

What Are Split King Movable Mattresses?

Health Benefits

Sleeping positions and bodily centers of gravity vary from person to person. When you sleep on a mattress that’s too firm or too soft, you run the risk of developing major health issues including low back or neck pain.

Individuals have a wide range of options to choose from when it comes to sleeping arrangements like this. No matter if you prefer to sleep on your side or your back, there is a mattress out there for you.

Comfortable For Home Moving

In general, king-sized mattresses are massive. Large mattresses are difficult to move, regardless of whether they are made of traditional coil springs or more modern flexible beds.

Two twin XL pillows can make your life easier. Separating and transporting these pillows is a breeze.

Individual Sleeping Space

It’s perfect for those prone to waking up when their companion tosses and turns in their sleep.

There are motion-blocking beds on the market now, but they can’t stop all of the motion. Using a shared bed could help you fix the issue once and for all.


The cost of adjustable king-sized beds is one of its most major drawbacks. It will cost you twice as much as purchasing just one product. For those on a restricted budget, it can be a problem.

The second issue is one that many people have to deal with on a regular basis. It is possible to move the mattress.

Because you’re combining two separate mattresses, you can’t expect a solid block to result. It’s possible to alter the surface while sleeping and mess up the scene the next day.

Five methods are provided below to help us deal with the issue.

Here, we’ll take a closer look at each adjustable bed fixing method.

Adjusting The Specialized Connector

An iron plate connector is included with the purchase of some split mattresses. Too much of a squeeze on this connector could cause your bed to shift.

The simplest solution is to increase the distance between frames. Pull the mattresses apart a few inches to adjust the connector. The bed should be re-aligned after the mattresses have been put in position.

The bed may bend somewhat in the centre if the link between two surfaces is too tight. Expand your sleeping area by stretching it out to its full potential.

Using A Fitted Bed Frame

The second way to secure two twin XL mattresses is to use a bed frame in the correct size. The structure’s design is entirely up to you.

Some people prefer to go the extra mile and add headboards, footboards, and drawers to their beds, while others are more content with just four wooden planks.

This is a simple and effective way to personalize your area. King-size frames can be found easily, as they are a common size. If you’re handy, you can even make your own.

Adding Non-Slip Pads

A non-slip mattress pad can help you separate the two beds if you find the first two solutions too inconvenient. Additionally, cushioning can be used by individuals who cannot afford a frame.

It’s a breeze to use. Insert the pads under the product’s base and you’re done. If the pads are strong enough, the bed will stay in position.

The main drawback is that you’ll still need to make occasional adjustments to these pads.

In addition to reducing tiny movements, adhesion tape can also be used. There are carpet and furniture double-sided tapes available.

Trying Bed Connector Straps

Two mattresses tethered together sound like a simple and practical way to save money and space.

Make use of bed restraints to keep you in place. Other bungee cords are not as safe because of a locking clasp and rope added by the manufacturer.

A 30-foot cord is ideal for wrapping around a king-sized double bed.

Stack the mattresses next to each other and wrap the straps around the mattress’s perimeter. Wrap them around the outside of the mattress so that you don’t feel weighed down while you sleep. Pull the strap through the buckle until it’s snugly fastened in place.

Padding The Gap Out

There is no need to use this strategy as a substitute for the other options. It doesn’t matter how firmly you fasten the two mattresses together; there will always be a space between them. As a result, cuddling with your lover will be awkward.

Tuck an old sheet between the mattresses, either rolled or folded. As long as the room isn’t too big, you can utilize a bed bridge instead.

How To Keep Split King Mattress From Sliding On An Adjustable Base

When it comes to maintaining a split king bed’s two mattresses together, let’s also talk about how to protect them from slipping off the base. Using an adjustable base to customize both mattresses is perhaps the most important benefit of split mattresses over other beds. While this may be the case for some people, others have complained about the mattresses slipping out of their beds.

If you’ve followed the steps outlined above, you may rest assured that the mattresses will no longer shift on either side. The only thing left to do is to use the bed’s foot retention bar or put grippers underneath to prevent slipping in other directions. If your mattress doesn’t come with a retainer bar, you can use a non-slip pad instead, which is what we recommend.

How To Keep The Sheets On A Split King Mattress

With an adjustable split king mattress, it can be difficult to find the right sheets. The purpose of the accessory will be defeated if the cover slides or bunches up. As a result, the split king bed requires twin XL linens to go with each of its mattresses.

We’ve discovered a way to make mattress covers more comfortable, and we’d want to share it with you. To ensure a snug fit, you should rapidly locate the corners in this position. However, if the sheets continue to fall off, you can always secure them using sheet straps on each corner.

To complete your bed, add a king-sized sheet set and a duvet. Mattress pads can be placed on top of the bed before the king-sized sheet is put on top.

Can Split King Beds Be Separated?

This does not mean that split monarchs can’t be separated. A split king bed is nothing more than two twin XL mattresses joined together. As a result, you can customize each mattress individually. Couples with various sleeping preferences will appreciate the split king’s ability to accommodate them.

If you follow our directions, you should be able to use straps to keep your mattresses and bases together. In order to have more control over your bed, we propose an adjustable base. As for moving the bed, each mattress can be moved on its own.

Can You Cuddle On A Split King?

In addition to the numerous health benefits that cuddling provides, it also helps us feel closer to our partner. When snuggling, you might notice the divided king’s delineation in the middle. Even yet, if you value each side’s autonomy, this isn’t a big deal.

You’ll get used to the gap with time. Using a sheet, mattress pad, or duvet can also alleviate this problem. It may be best to just get a true king-size mattress if you and your partner have the same preferences when it comes to sleeping arrangements.

How to Keep Your Mattress in Good Shape Longer

Protecting your mattress and home from disaster is as simple as following our list of the ten greatest ways to take care of it.

1. Make sure your mattress is properly supported.

You may not always need to purchase the matching foundation or box spring with a new mattress, but it is crucial to ensure that your mattress is supported properly. Preventing early wear and tear is a benefit of this method.

For more information, speak with the product’s creator or review the manufacturer’s warranty policy. The majority of the time, box springs are only utilized with spring mattresses, however memory foam and other speciality mattresses often need a strong, stable foundation.

The weight of sleepers and the mattress should be supported by a bed’s frame, and queen and king beds should have center support bars for added stability. Depending on the mattress and weight, wide-slat platform beds may require additional support.

Once or twice per year, you should look over your bed’s support to make sure there aren’t any cracked or damaged pieces that could affect your mattress’s longevity and comfort.

2. Use a mattress protector from the beginning.

One of the greatest and simplest ways to ensure the longevity of your mattress is to use a mattress protector, which we’ve previously discussed.

A high-quality mattress protector provides waterproof protection in the event of a spill or accident, as well as reducing the amount of dust, debris, and filth that enters your bed.

This keeps skin oils and sweat off the bed, which helps keep allergens like mildew and dust mites from building up. When mishaps do happen, a protector makes cleanup a breeze, and many of the newer models are just as comfortable to sleep on as a fitted sheet.

3. Wash bed linens regularly.

Sweat, oils, hair, and skin cells are all shed while you sleep. Crumbs are left behind when people eat in bed, and animals can bring in a wide variety of items. Bacteria and dust mites thrive in mattress layers that are infested with disgusting stuff.

Bed linens and blankets should be laundered every week or two, according to most cleaning professionals. Even if you use a mattress protector, you should still wash your sheets regularly. Additionally, the mattress protector should be washed in accordance with the manufacturer’s instructions.

4. Get pets separate beds to snuggle in.

If you don’t want anything on your bedding, don’t allow your pet snuggle up on your mattress in the first place.

Your bed will be soiled even if your pet is well-groomed because they wander outside and slobber and shed hair and cells much like people. An otherwise decent mattress can be ruined by accidents caused by pets.

5. Rotate the mattress regularly.

No matter the size or the material, rotating a mattress on a regular basis is beneficial to all mattresses. While some manufacturers claim that rotation does not promote more even wear, the converse is also true: not rotating increases the likelihood of depressions and softening.

Rotate the mattress from top to bottom every two to six months. Breaking in a mattress is especially critical in the first few years.

6. No jumping on the bed!

Your mother was right when she cautioned you not to jump on the bed. Foundations, frames, and even foams can all wear down more quickly if you are tough on the mattress.

7. Take care when moving your mattress.

In order to avoid damaging your mattress during the moving process, wrap your mattress in plastic and avoid folding it. In addition to protecting the mattress from dirt and wetness, these heavy-duty mattress bags can also be used to guard against scuffs and scratches.

In general, it’s better to move a mattress upright on its side to avoid creases or sagging during transport. Mattress covers with handles are normally not recommended for moving or dragging the mattress.

8. Don’t bring home unwanted hitchhikers.

An infestation of bedbugs is one of the fastest and most efficient ways to damage a mattress.

When sleeping away from home, always inspect the bed from signs of bed bugs and try to keep luggage off the floor. If you suspect bedbugs, Texas A&M University has a few tips for preventing bringing them back home.

Check for bed bugs and keep luggage off the floor if you’re staying somewhere other than home. You can avoid taking bedbugs back to your own home by following these precautions from Texas A&M University.

9. Let the light in occasionally.

If you have a dry and sunny day once or twice a year, remove your mattress and let it air out for a few hours (though if bedbugs are possible, leave the cover on).

To keep dust mite populations in check according to a research by Kingston University, this prevents excess moisture from both sleepers and humidity.

10. Follow manufacturer cleaning directions.

Cleaning your mattress on a regular basis will help you sleep better and maintain your mattress healthy.

To remove surface dust, most beds should be vacuumed with a hose attachment to remove stains and general dirt from the surface.

It’s best to wait to make the bed until the stains have completely dried before using a gentle water and soap solution. Foams can lose their integrity if cleaned with strong chemical cleaners.

Vacuuming should be done every one to three months, depending on the degree of dust, allergies, or personal preference, and stains should be cleaned as needed with spot treatments.

The essentials of mattress care and maintenance are the same regardless of the type or brand of mattress. To summarize, make sure the bed is free of debris, secure it from harm, support it, and rotate it regularly to promote even wear.

Mattress lifespan depends on many factors, but following these best practices can help ensure that you enjoy years of healthy sleep and that your investment lasts as long as possible. Whether you are looking at more traditional brick-and-mortar stores, or a new bed in a box mattress companies, know that a 10-year warranty on your mattress is considered an industry standard.


If you follow these tips, you can ensure that your mattress lasts as long as possible and that you get the most out of your investment. For both traditional brick-and-mortar and new bed-in-a-box mattress firms, 10-year warranties are considered the industry standard.
