Is a Split King Mattress Right for You? Pros, Cons, and Considerations

Share:

These days, there are so many options to make your sleep better: foam, hybrid, and dual hybrid mattresses, moisture-wicking bedding and pajamas, and adjustable bed frames. With all these choices and terminology, it's understandable to feel a bit overwhelmed. But don't worry, we've got your back! We'll help you find the perfect bedroom setup tailored just for you.

One of the terms that is often misunderstood is "Split King." While most people understand that this means it's a King-size bed setup, the “split” portion can be a little confusing. Let's take a deeper dive into what exactly it is and if it's the right bed for you.

What is a Split King Mattress?

Unlike traditional mattresses that provide a single sleeping surface, a Split King bed offers the flexibility of personalizing each side of the bed. It consists of two Twin XL mattresses placed side by side to create a King-size bed. Each half of the Split King mattress is typically 38 inches wide by 80 inches long, and when combined, they form the Standard King-size dimensions of 76 inches wide by 80 inches long.

When it comes to Leesa’s Split King mattresses, they measure 78 inches wide and 80 inches long. This is because each Twin XL mattress is 39 inches wide by 80 inches long. By placing two Twin XL mattresses side by side, you get a combined width of 78 inches, maintaining the standard height of 80 inches.

A Split King mattress is a convenient way to create a personalized sleep experience for couples by combining two Twin XL mattresses side by side. Leesa offers a range of King-size mattresses, including the regular King and California King options, as well as the option to choose a Split King set up with two Twin XL mattresses.

Benefits of a Split King Mattress 

Split King mattresses offer incredible benefits for couples. Here's what makes them so great:

Individualized Sleeping Preferences for Couples

With a Split King mattress, you and your partner can customize the sides of the bed. That means choosing the mattress type, firmness level, and even adjusting positions independently. It's like having a tailored sleep experience made just for you!

The physical split, while it doesn't create an actual hole, provides a built-in line of separation, so each partner can stay on their side of the bed, or meet in the middle to cuddle.

Reduces Snoring and Back Pain

Snoring can put a damper on a good night's sleep, not just for the snorer but also for their partner. But guess what? With a Split King mattress, you and your partner can raise your side of the bed to find that sweet spot that opens up your airways and reduces snoring. Say goodbye to those loud nighttime noises and hello to quieter, more peaceful sleep!

Peaceful Motion Isolation

No more getting jostled awake! The split design of a Split King mattress helps reduce the transfer of motion between the two sides. So, even if your partner is a restless sleeper, you can snooze away undisturbed.

Support That Suits You

We're all unique, and so are our bodies and sleep positions. With a Split King mattress, each partner can pick the perfect level of support. If one of you wants a firmer mattress and the other prefers something softer, no worries! You can both have exactly what you need for a comfy night's sleep.

Durability

Split King mattresses are made up of two Twin XL mattresses. That means you can flip and rotate them independently, which helps even out wear and tear. It's like giving your mattress a longer lifespan to keep you comfy for years to come.

Disadvantages of Split King Mattresses 

While Split King mattresses offer a range of benefits for couples, it's important to consider the potential disadvantages as well. These drawbacks may affect certain aspects of sleep and bed functionality. From the challenges of finding compatible bedding to the potential for a noticeable gap between the mattresses, being aware of the downsides can help you make an informed decision. 

Difficulty Finding The Right Foundation

One potential challenge with a Split King mattress is finding the right foundation or base. Without the appropriate support, the mattresses may slide apart over time, creating a noticeable gap between them. To address this, the recommended setup is to use two Twin XL adjustable bases. This not only provides proper support but also allows for individual customization. Each partner can adjust their side of the bed independently, ensuring a secure and aligned setup while enjoying personalized comfort.

Bedding Challenges

Finding the right bedding for a Split King mattress can be a bit more challenging compared to traditional mattress sizes. Standard King-size bedding may not fit properly on the divided mattress, requiring separate sets of Twin XL sheets, blankets, and mattress protectors. This can add complexity and potentially increase the cost of purchasing bedding for the Split King set up.

Limited Bed Sharing Space

The middle divide between the Twin XL mattresses in a Split King setup can create a noticeable gap in the center of the bed. This gap may restrict the shared space for couples who enjoy snuggling in bed or prefer a larger, uninterrupted sleeping surface. It's important to consider personal preferences and the need for sufficient space before opting for a Split King mattress.

Cost Considerations

Split King mattresses, along with the bases and bedding required, can be more expensive compared to a Standard King or Queen-sized mattresses. The individual components and customization options contribute to a higher overall cost. It's important to factor in budget considerations when deciding on a Split King mattress.

Potential for Uneven Wear

Since Split King mattresses consist of two separate Twin XL mattresses, there is a possibility of uneven wear over time. Each side of the bed may experience different amounts of use and pressure, leading to potential variations in mattress condition and longevity. Regularly rotating and flipping the mattresses can help minimize this issue, but it's still worth considering the possibility of uneven wear.

How to Choose the Right Split King Mattress?

Choosing the right Split King mattress involves considering several factors to ensure it meets your specific needs and preferences. Here's a guide to help you navigate the selection process:

Size and Compatibility

Confirm that the dimensions of the Split King mattress will fit your bed frame and bedroom space. Additionally, ensure that the Split King setup is compatible with the adjustable bases, if applicable.

Material and Construction

Consider the materials used in the mattress and their suitability for your sleep preferences. Common options include memory foam, latex, hybrid (combination of foam and innerspring), and innerspring mattresses. Each material offers different levels of support, comfort, and motion isolation, so choose the one that aligns with your preferences.

Firmness Level

Determine your desired firmness level, whether you prefer a plush, medium, or firm mattress. Keep in mind that individual preferences may differ for each partner, so look for a Split King mattress that allows for customization on each side.

Support and Pressure Relief

Look for a Split King mattress that provides adequate support to align your spine and relieve pressure points. Consider your preferred sleep position and any specific requirements, such as extra support for back pain or targeted pressure relief for sensitive areas.

Cooling and Breathability

If you tend to sleep hot or live in a warm climate, choose a Split King mattress with cooling features such as breathable materials, airflow-enhancing designs, or gel-infused foams to promote a cooler and more comfortable sleep environment.

FAQs

What Kind Of Bedding Should I Use For My Split King Bed?

We recommend using Twin XL fitted sheets for each Split-King mattress to maximize your time and energy. The elastic band ensures a snug and secure fit around the bed when adjusting it in different positions. In addition, it will make it easier to put on and take off the sheets. There are then two options: you can use a single flat sheet to give the appearance of a single mattress or a flat sheet for each bed. Using separate sheets allows you to cater to each sleeper's comfort and fabric preferences. Similarly, you can choose between a single duvet or two duvets.

Is a King bed and an Eastern King bed the same thing?

That's right! In the world of mattresses, an Eastern King is the same as a Standard King. The standard dimensions of both mattresses are 76"x 80" (6.3' x 6.6'). An Eastern King is simply another name for a Standard King. Eastern King is more commonly used to contrast Western Kings (also called California Kings).

What is the difference between a King and Queen size bed?


When comparing King and Queen-size mattresses, it is important to note that their size is the biggest difference. King mattresses measure 76" x 80" (6.3' x 6.6'), while Queen mattresses measure 60" x 80" (5' x 6.6'). While both mattresses offer the same length, the King mattress has 16 inches more width than the Queen mattress.

Consider the following factors when choosing the right mattress: your comfort needs, the size of your room, whether you will sleep alone or with a partner, and your sleeping position. A Queen-sized bed may be a good choice for those who sleep alone, spread their limbs while sleeping, are compact sleepers, or are under 6'2". However, many couples also find the Queen size meets their needs. Lastly, linens and other accessories for Queen-sized beds are generally less expensive than those for King-size beds. We recommend a King-sized bed for people with larger rooms, over 6'2", and those who prefer more wiggle room.

How Much Does a Split King Adjustable Bed Cost?

Split-King adjustable bases from our collection are designed with every sleeper's taste in mind and can be customized at each step. Depending on your preference, our bases start at $2,598* and can be complemented with our headboard brackets for an additional $69*. To ensure personalized comfort, we offer all of our mattresses in Twin XL sizes, except for our kid's mattress and trundle bed. Additionally, the legs on our Split-King base are adjustable in half-inch increments to reach your preferred height. Finally, all our adjustable bases come with wireless remotes, USB charging ports, massage capabilities, and under-bed LED lighting, providing a more relaxing night's sleep.

Split King vs. King Bed: What’s the Difference?

A King mattress is one piece, but a Split King is two Twin mattresses placed on the same base or bed frame. A Split King is great for couples with an adjustable bed or who don't agree on the same type of mattress. Both offer plenty of room to spread out.

What base should I use?

You have a few options when it comes to the right base for a Split King mattress. The best base setup for a Split King mattress (and the most common reason people choose a Split King) is two Twin XL adjustable bases. This allows for the customization we talked about earlier: your partner can elevate their side of the bed while yours is completely flat, or vice versa. There are many other bed base options. Read our full guide to bed bases.

Who Needs a Split King Setup?

As we mentioned, a Split King setup is best for those couples who want a split adjustable base. This allows each partner to customize their side of the bed, whether they both prefer a different mattress or just have different sleeping preferences.

Can you feel the split in a Split King bed?

In a Split King bed, you might feel a slight split between the Twin XL mattresses, but as you get used to it, you'll likely pay less attention and enjoy your sleep. In many cases, the feeling of the split becomes less noticeable over time as you adjust to the unique setup. Plus, the benefits of personalizing each side of the bed often outweigh any minor sensation of the split. So, rest assured that a Split King bed can still provide a comfortable and restful sleep experience for you and your partner.

Is it hard to put sheets on a Split King bed?

Putting sheets on a Split King bed isn't too tricky once you get the hang of it. It just takes a bit of extra effort since you'll need separate sheets for each side. But hey, it's worth it for the personalized comfort you get with a Split King setup.

How to keep Split King mattresses together?

You can use a mattress retainer bar or strap that spans the gap between the mattresses, securing them in place. Another option is to use a non-slip mattress pad or gripper that helps prevent the mattresses from shifting apart. Additionally, ensuring that both Twin XL mattresses are placed on a sturdy and compatible bed frame or base can also help maintain their alignment and keep them together.
