A split mattress upon an adjustable base can benefit couples who have different sleep needs. We’ll introduce our favorite adjustable bases for split kings and go over who may benefit the most from them and who may want to steer clear.

Emma Powerbase Pro Adjustable Bed – Best Support
Emma Powerbase Pro Adjustable Base
This adjustable frame from Emma has a sturdy steel construction and several presets for the head and feet.
Expert Opinion
Emma started out with creating highly supportive mattresses, and now they’ve created a highly supportive split-king base in their Powerbase Pro Adjustable Bed. It has a sturdy steel frame with presets for the head and feet. This allows for many different activities in bed, from watching TV to reading and enjoying a zero-gravity recline. The base also comes with a variety of stackable leg options and added features such as voice command and dual USB charging stations.
Note: Because this product isn’t yet available as a traditional split king, we recommend purchasing two twin XL mattresses and two twin XL adjustable frames, then pushing them together.
Who the Emma Powerbase Pro Adjustable Bed is Best for
- Back sleepers: The Powerbase Pro is compatible with the original Emma mattress and the Emma Hybrid Comfort, both of which we recommend to back sleepers, thanks to their blend of comfort and support.
- Stomach sleepers: We also recommend these mattresses to anyone who sleeps in the prone position. The beds are supportive enough to keep you from sinking too far into the layers, which can throw the spine out of alignment.
- Heavy people: Folks over 250 pounds usually get the support they need on Emma mattresses (especially the more supportive Hybrid Comfort), and will get even more support with the added adjustable bed frame.
Who Should Avoid the Emma Powerbase Pro Adjustable Bed
- Budget shoppers: As comfortable and supportive as the Emma Powerbase Pro Adjustable Bed is, it’s definitely one of the pricier options out there. Two twin XLs — the best way to create the split king dimensions — each run you $1,449 before discounts.

What is a Split King Adjustable Bed?
A split king adjustable bed is simply a king bed that has been split right down the middle to create independent sides. Each side has the same dimensions as a Twin XL (38 inches by 80 inches) but create a king sized bed when pushed together. A split king is unique because it allows two people to customize their side of the bed. To learn more about split kings, check out our guide to them or head on over to our best split king mattress round up to see some of our top picks.
What to Look for In An Adjustable Bed for Split Kings
When shopping for an adjustable bed, you may be overwhelmed by the wide variety of options available. Some adjustable bases are simple, while others come with additional premium features or high technology. It’s important to consider why you’re buying an adjustable bed and what you hope to get out of it. For example, you may be buying an adjustable bed to help with muscle pain, so you may want to narrow your search to bases with massage features to help ease some of the pain. If reducing snoring is your main concern, you may want to look for a base that comes with anti-snoring presets, which will automatically put you in a position to help decrease snoring.
Let’s now go over some of the key factors to consider when shopping for an adjustable base for split kings.
Mattress Compatibility
Foam mattresses are usually the best mattresses for adjustable bases due to their flexible nature that can conform to the changing angles of the base. Many hybrid mattresses are also compatible. It may be more difficult to use an innerspring mattress on an adjustable base because the springs can prevent them from bending.
Weight Limit
Different sleepers have different support needs, so you’ll want to consider the materials the base is made of. Some sleepers may need a bit of extra support depending on their body type and sleeping style, so they’ll want to seek out durable materials. Before purchasing, check how much weight the base can support to ensure it can support both you and your mattress.
Assembly
Some bases may be complicated to set up and you may need help with assembly. However, many companies try to make their bases easy to assemble, and many require no tools to set up. Some people, like those with disabilities or extreme pain, are physically unable to set up bases on their own. In this case, check the company policy, because some brands will send movers to set up the base for you.
Features
Adjustable bases come in a variety of styles, and some come with high-tech features. Think about what kind of adjustable bed you want and the features you need. Are you looking for a bed with premium features such as massaging motors? Or do you want one that just elevates the head and feet? You may want one with easy presets, like zero-gravity or anti-snore. Once you know what you want in a base, it will make your search easier.
Size and Appearance
You’ll want to choose an adjustable base that is able to fit in your bedroom. Some bases can be heavy and bulky, so you may want to look into one with a slim design that won’t be difficult to move if you tend to move a lot or frequently rearrange your furniture.
Many adjustable bases are able to fit inside an existing bed frame. If you want to use the adjustable bed on an existing frame, be sure to check if the base is able to do that because some can only stand alone. If you plan to use the base as it comes, consider the aesthetics of the adjustable base. Some are sold in styles that look neutral and can go with any decor, while others may come in bolder colors or eye-catching designs.
Price
Adjustable bases can range in price depending on the brand, features, and warranty. The prices in this roundup range from $1,398 to $2,798 for a split king size at full retail. The average price of all these adjustable bases is about $1,908 for a split king size.
Most brands have frequent sales and discounts offered on their adjustable bases, which you can take advantage of. Check out our guide on the best time to buy for more information on getting the best deal possible.
Trial & Warranty
Most companies offer a warranty on their adjustable bases, so it can be replaced if it’s faulty or breaks naturally. The length of the warranty can also be a good indication of quality, as a longer warranty means the company believes its product will hold up for a long time.
Many bases do not come with a sleep-trial period and are final sale with no returns or exchanges offered, so be sure to read the fine print when making your purchase. However, some companies will also offer a trial period on adjustable bases. You pay for the base and sleep on it for a period of time, but you can exchange it or return it for a full refund if you don’t love it.
Split King vs King Adjustable Beds
In this guide, we focused specifically on adjustable bases that are sold in the split king size and pairs great with split king mattresses. A split king and a king adjustable bed are very similar, but there are some key differences that set them apart. The main difference is whether each side of the bed operates independently or moves as one unit.
Common Problems With a Split King Adjustable Bed
A split king is a unique size, so it may come with some unique issues that you’ll want to be aware of before purchasing.
Gap and Seam
Think of a split king bed as just two twin XL beds pushed together. The purpose of this type of bed is to have each side operate independently. The structure and feel of the mattresses used can also be completely different, so each person can have a bed that fits their preferences.
Therefore, there will be a slight space between the two mattresses. Even if you push the mattresses super close together, you may be bothered by the “seam” running down the middle. However, you can purchase a “gap filler” that goes under your sheets and may help hide the separation.
Compatible Sheets and Bed Frames
A split king mattress is a common size, but many companies still don’t sell products that work with a split king. If you have your heart set on a certain brand of model of mattress, you may be disappointed if it is not sold in the split king size. It may also be more difficult to find bedding accessories such as sheets and bed frames that are sold in the split king size.
Noise
If you sleep with a partner, you may be all too familiar with being disturbed at night by their movement. Some people complain that adjustable beds are noisy while they adjust. If your partner adjusts their side of the bed in the middle of the night, you may be woken up by the sound of it moving. Some massaging bases market themselves as “whisper quiet” but still emit a humming noise while in use, which may disturb some sleepers.
Weight
Adjustable beds in general are heavy. They need to be made from sturdy and durable material in order to properly support their sleepers. If they have massaging engines and power boxes, they’ll be even heavier. With a split king, you’ll be assembling and moving not one heavy bed, but two.
Cost
Split king adjustable beds are typically more expensive than king adjustable beds. This may be frustrating to some shoppers who want a split king but don’t want to pay the extra cost.
FAQs
Is split king the same as two twin XLs?
Yes. Dimensions-wise, each side of a split king bed equals one twin XL.
What kind of mattress do I need for a split king adjustable bed?
You’ll need a split king mattress, or twin XL mattresses. A split king base is no use if the mattress isn’t also split.
Do people like split king adjustable beds?
Many do, particularly couples who have different sleeping needs. For example, one person may go to sleep earlier while the other likes to sit up in bed and read. One partner may need to sleep with their head elevated to prevent snoring while the other wants their legs elevated above their head to promote circulation.
How do you keep a split king adjustable bed together?
There are plenty of products on the market designed to help keep your split king adjustable bed together. A popular option is the use of velcro straps. A fitted bed frame can also help keep the bases together and in one place.
