1. Understanding the Split King Mattress
A split king mattress is a king-size mattress constructed from two separate twin XL mattresses. Each mattress measures 38 inches wide by 80 inches long, totaling the standard king size of 76 inches wide by 80 inches long when placed side-by-side. This design offers unique advantages for couples with different sleep preferences or needs, offering a blend of shared space and individualized comfort.
1.1. Dimensions of a Split King Mattress
- Width: 76 inches (193 cm)
- Length: 80 inches (203 cm)
- Individual Mattress Size: Two Twin XL mattresses, each 38″ x 80″
1.2. Key Differences Between a Split King and a Regular King Mattress
| Feature | Split King Mattress | Regular King Mattress |
|---|---|---|
| Construction | Two separate Twin XL mattresses | One single king-size mattress |
| Customization | Allows individual firmness and support levels for each side | Uniform firmness and support across the entire mattress |
| Motion Transfer | Minimizes motion transfer between partners | Motion transfer can be more noticeable |
| Adjustable Base Compatibility | Ideal for use with split king adjustable bases, enabling independent adjustments for each side | Can only be used with a standard king-size adjustable base, providing uniform adjustments for both partners |
| Sheet Requirements | Requires two Twin XL fitted sheets and a king-size top sheet | Requires standard king-size sheets |
| Weight & Movement | Easier to move and handle due to the smaller size of each individual mattress | Can be difficult to move and maneuver due to its large size and weight |
1.3. Who Is the Split King Mattress For?
A split king mattress is particularly well-suited for:
- Couples with Different Sleep Preferences: Partners who prefer different firmness levels or mattress types.
- Individuals with Medical Conditions: People who need to adjust their sleeping position due to back pain, sleep apnea, or other health issues.
- Light Sleepers: Those easily disturbed by a partner’s movements during the night.
- Tech-Savvy Sleepers: People who enjoy the flexibility and customization offered by adjustable bases.
2. Advantages of a Split King Mattress
The split king mattress offers numerous benefits, from personalized comfort to enhanced convenience. Here’s a detailed look at its key advantages:
2.1. Personalized Comfort
2.1.1. Different Firmness Levels
One of the most significant advantages of a split king mattress is the ability for each partner to choose a mattress with a firmness level that suits their individual needs. For instance, one partner might prefer a firmer mattress for back support, while the other may prefer a softer mattress for pressure relief.
2.1.2. Different Mattress Types
Couples can also opt for different mattress types on each side, such as memory foam, latex, or innerspring, to cater to their specific comfort preferences.
2.2. Reduced Motion Transfer
2.2.1. Minimizing Sleep Disturbances
A split king mattress significantly reduces motion transfer, meaning that movements on one side of the bed are less likely to disturb the person sleeping on the other side. This is particularly beneficial for light sleepers or those with restless partners.
2.2.2. Independent Support Systems
Each twin XL mattress functions as an independent support system, absorbing movement and preventing it from spreading across the bed.
2.3. Adjustable Base Compatibility
2.3.1. Individualized Positioning
Split king mattresses are ideal for use with split king adjustable bases, which allow each partner to independently adjust the position of their side of the bed. This can be particularly helpful for:
- Reading or Watching TV in Bed: One partner can sit upright while the other lies flat.
- Relieving Pressure Points: Adjusting the bed to elevate the legs or torso can help alleviate pressure points and improve circulation.
- Managing Medical Conditions: People with conditions like sleep apnea, acid reflux, or back pain can benefit from customized sleeping positions.
2.3.2. Enhanced Comfort and Convenience
Adjustable bases often come with additional features such as massage, zero-gravity settings, and programmable presets, further enhancing comfort and convenience.
2.4. Easier to Move and Handle
2.4.1. Lighter Weight
Compared to a single king-size mattress, each twin XL mattress is lighter and easier to move, making it simpler to transport the mattress during relocation or redecorating.
2.4.2. Maneuverability
The smaller size of each mattress also makes it easier to maneuver through doorways, hallways, and staircases.
2.5. Potential Health Benefits
2.5.1. Alleviating Back Pain
The ability to customize firmness levels and sleeping positions can help alleviate back pain by providing targeted support and pressure relief.
2.5.2. Improving Circulation
Adjustable bases can improve circulation by elevating the legs, which can be particularly beneficial for people with varicose veins or edema.
2.5.3. Reducing Sleep Apnea Symptoms
Elevating the head can help reduce sleep apnea symptoms by keeping the airways open.
3. Drawbacks of a Split King Mattress
While split king mattresses offer numerous advantages, they also have potential drawbacks that consumers should consider before making a purchase:
3.1. Cost
3.1.1. Higher Initial Investment
Split king mattresses and adjustable bases tend to be more expensive than their standard king-size counterparts. This is due to the increased complexity of the design and the need for two separate mattresses.
3.1.2. Additional Expenses
The need for two sets of twin XL fitted sheets can also add to the overall cost.
3.2. The Gap in the Middle
3.2.1. Potential Discomfort
Some sleepers may find the gap between the two mattresses uncomfortable, particularly if they tend to move around a lot during the night.
3.2.2. Gap Fillers
While gap fillers are available to bridge the space between the mattresses, they may not completely eliminate the issue and can sometimes be cumbersome to use.
3.3. Sheet Compatibility
3.3.1. Need for Twin XL Fitted Sheets
Split king mattresses require two twin XL fitted sheets, which may be less readily available and more expensive than standard king-size sheets.
3.3.2. King-Size Top Sheet
While a king-size top sheet can be used, it may not fit as snugly as it would on a standard king-size mattress.
3.4. Aesthetic Considerations
3.4.1. Visual Gap
The visual gap between the two mattresses may not appeal to everyone, particularly those who prefer a seamless, uniform look.
3.4.2. Styling Challenges
Styling a split king bed can be more challenging than styling a standard king-size bed, as it requires coordinating two separate sets of bedding.
3.5. Weight Limitations
3.5.1. Adjustable Base Capacity
Split king adjustable bases may have weight limitations for each side, which could be a concern for heavier individuals.
3.5.2. Mattress Durability
The durability of each twin XL mattress may be affected by the weight and sleeping habits of the individual using it.

8. Addressing Common Concerns
Here are some frequently asked questions and concerns about split king mattresses:
8.1. Can You Feel the Split in a Split King Mattress?
8.1.1. Mattress Design
While there is a gap in a split king mattress because it is two mattresses joined together, most sleepers can’t feel it because the mattresses are designed to fit so closely together.
8.1.2. Solutions
If you prefer not to feel the gap at all, options include:
- Using a bungee cord to strap the legs together
- Purchasing a “gap filler,” which is typically a piece of foam you put between your mattresses
- Using a king-sized mattress topper on top
8.2. What Size Headboard Do You Need with a Split King?
8.2.1. King-Size Headboard
Adding a headboard is a great way to protect the wall behind your bed—plus, the right headboard can add a stylish and upscale backdrop!
8.2.2. Headboard Brackets
All you need is a king-size headboard and the right headboard brackets to connect it to your adjustable bed.
8.3. Do You Need Special Sheets for a Split King Bed?
8.3.1. Twin XL Fitted Sheets
A split king bed will need slightly different bedding than a traditional king mattress. The two separate mattresses that make up the one bed will each need their own fitted bed sheet.
8.3.2. King-Size Top Sheet
On top of the fitted sheets, you can then layer on a single king top sheet along with a single quilt and duvet.
8.4. Is a Split King the Same as Two Twin Mattresses?
8.4.1. Twin XL Mattresses
At this point you might be wondering: can’t I just put two twin XL mattresses next to each other to create a split king?
8.4.2. Functionality
The answer is… yes and no! Technically, a split king isn’t really a size—it’s just two separate twin XL mattresses. But it’s so much more than that, too! With two twin XL mattresses, you’ve got plenty of options.
8.5. What Other Problems Are Common with Split King Adjustable Beds?
8.5.1. Gap in the Middle
The most common split king problem that people wonder about is the gap in the middle, as we mentioned in the last FAQ.
8.5.2. Mattress Sliding
Beyond that, some people worry about the mattress sliding down when you’re elevating your head. To combat this, look for an adjustable base with a retainer bar at the foot and non-skid material beneath each leg.
8.5.3. Wall-Hugging Technology
Another common complaint to note: as you raise the head of some adjustable bases, the entire bed moves forward and can leave you far from your nightstand or anything else by the side of your bed. Some companies add “wall-hugging” or “wall-aligning” technology to their base to help with this; others (like our GhostBed Adjustable Base) are simply designed to keep you close even as the bed adjusts.
