Why You Should Trust Us

Our goal is to help people discover evidence-based strategies for improving their sleep. Our diverse team of sleep experts tested dozens of split king adjustable beds to bring you our top picks on the market today. These beds offer the best balance between cost, features, and customer service policies.

What Is a Split King Adjustable Bed?

A split king adjustable bed is made up of two twin XL mattresses sitting side by side on two connected adjustable bed bases. This kind of bed base keeps your bed raised off the floor and provides crucial support to your mattress. Adjustable beds are unique because they allow you to raise or lower the head and foot of the bed to customize your sleeping position.

While a standard king adjustable bed contains a single king mattress on an adjustable base, the two twin XL mattresses that make up a split king adjustable bed offer an even greater level of customizable comfort at the same size. Combined with a dual adjustable base, this design allows two sleepers to independently adjust their side of the bed.

Each sleeper can also choose a mattress with a different firmness level, which can be helpful if you and your sleep partner have different needs or preferences. Split king adjustable beds also often include premium features such as massage settings, under-bed lighting, and charging ports.

Split King Adjustable Bases

A split king adjustable base allows you to change the position of your upper or lower body. While adjustable bases originated in health care settings, a number of sleep brands now offer models designed to increase your comfort when sleeping at home. Adjustable beds can be purchased in-stores or online.

Split king adjustable bases are usually made from two connected twin XL adjustable bases. This can make split king adjustable beds easier to assemble and move because you can disconnect the two halves of the bed.

Some brands use a split king base for both their split king and regular king adjustable bed options. If this is the case, the regular king may have a sync cable or a specially programmed remote that connects to both sides of the bed and allows both bases to move together.

California split king adjustable beds are also available, though the options depend on the brand. California king beds are slightly longer and narrower than traditional king beds.

Benefits for Couples

Split king adjustable beds can be a good choice for couples because of their many features, which are designed to help each partner sleep comfortably and without disturbing the other.

  • Accommodates different sleep preferences: Split king adjustable beds are made up of two twin XL mattresses. Each person can choose their own mattress style, firmness, and support based on their personal comfort preferences.
  • Independence for bedtime habits: With independently adjusting sides, you can stick to your preferred bedtime routine without worrying about disturbing your partner. One person can keep their side of the bed inclined to read or watch TV while the other person lies flat.
  • Motion isolation: The split king adjustable base design creates two separate sleep surfaces that sit side by side. This allows for excellent motion isolation, as each mattress transfers very little motion to the other. You should be able to get in and out of bed or change sleep positions without waking up your partner.
  • Plenty of sleeping space: The king size sleep area provides each sleeper with ample room to stretch out during the night.

Are Adjustable Beds Worth It?

An adjustable bed comes with a variety of benefits that may help make up for the slightly higher price tag.

Adjustable beds provide a wide range of customizable sleep and lounging positions. Each person using the bed can choose the position that’s most comfortable for them. This may help relieve joint aches and pains as well as snoring without the need to compromise on comfort. It can also make it easier to get in and out of bed.

Adjustable beds often come with a number of premium features. These include wireless remote or smartphone controls, massage settings, under-bed lighting, programmable memory positions, and other features to make your time in bed as comfortable as possible. You may also be able to receive Medicare or other health insurance coverage for part of the bed’s cost if it’s part of a treatment plan prescribed by a doctor.

Benefits of an Adjustable Bed


Angled Sleep Positions

These positions elevate your upper or lower body, allowing you to choose from many different sleep positions beyond just lying flat.

Reclining Position for Lounging

The reclining position raises the head of your bed so you can sit comfortably while watching TV, reading, working, or relaxing with your partner.

Pain Relief

Elevating parts of your body or using preset positions like zero gravity may help promote neutral spinal alignment and reduce common pain points, such as the lower back.

Reduce Snoring

Sleeping in an incline position or an anti-snore preset position may help reduce snoring.

Assist Movement

For people experiencing reduced mobility, an adjustable bed can make getting in and out of bed much easier.

Relief from Health Conditions

Changing your sleep position can help with certain health conditions, including acid reflux, snoring, and frequent nighttime urination.

Health Insurance May Cover Cost

Your health insurance may cover part of the cost for an adjustable bed if it’s prescribed by your doctor to treat a health condition.

Premium Features

Premium Feature


Many high-end adjustable beds come equipped with a built-in massager. This can include multiple speeds and custom options for head, legs, or full body.

Zero-Gravity and Anti-Snore Preset Positions

Adjustable bases often come with pre-programmed bed positions. Zero gravity keeps your body in a neutral, low-impact position, while anti-snore helps open the airway to prevent snoring.

Programmable Memory Positions

This feature lets you save your favorite positions for different activities like sleeping or reading and switch between them with the click of a button.

USB Charging Ports

Some models feature USB ports, so you don’t have to rely on a wall outlet for charging devices like smartphones, e-readers, and tablets.

Under-Bed Lighting

Built-in under-bed lighting makes it easy to see where you’re going in the middle of the night without waking your partner.

Wireless Remote and App Controls

A wireless remote allows you to easily control your bed’s features without getting up. Some models also let you control your bed from your phone.

Smart Functions

Smart functions go beyond normal smartphone control. This can include Alexa compatibility, voice control, and sleep tracking.

Choosing an Adjustable Split King Bed

There are a variety of factors to keep in mind when deciding whether to purchase a split king adjustable bed.

Do You Need a Special Mattress for an Adjustable Bed?

The best mattresses for an adjustable bed are memory foam, latex, or hybrid. These styles are flexible enough that they can bend with the moving base. Traditional innerspring mattresses without pocketed coils are not recommended due to their more rigid design.

Keep in mind that a split king adjustable bed requires two twin XL mattresses. This allows couples to get the most benefit from the split design, including independent adjustments and different mattresses to suit each person’s comfort preferences.

What to Consider in a Split King Adjustable Bed

  • Premium features: When comparing different adjustable split king bed models, think about any premium features that you want your bed base to include. These features may increase the price of the bed, but it’s important to remember that you’ll probably use and enjoy this bed for a very long time.
  • Weight capacity: Consider both your weight and your partner’s. Higher-end models are likely to be more sturdy and have a higher weight capacity.
  • Bed height: Make sure to take into account your desired bed height. This includes the height of the adjustable base as well as the mattress. Higher beds can be easier to get in and out of, especially for sleepers with reduced mobility. Keep in mind that some models may allow you to adjust the height of the bed, while others are fixed.
  • Size and appearance: Choose an adjustable bed that fits with your current bedroom decor. Remember that adjustable bases don’t usually require a separate bed frame or other foundation. However, you may be able to combine your new adjustable split king with your current headboard if their sizes match.
  • Price and financing: The typical cost for a split king adjustable bed can range from $1,000 to $3,000. Adjustable beds cost more than standard bed bases due to their more complex construction and luxury features. Many retailers offer financing options to help shoppers fund their purchase.
  • Warranty and sleep trials: A sleep trial allows you to try a product at home and return it within a certain time frame if you’re not happy with how it performs. Not all adjustable beds come with a sleep trial, but most come with a limited warranty. Make sure to check whether the manufacturer includes the electronic parts of the adjustable bed base in their warranty or if they’re covered by a separate policy.
  • Assembly and delivery: Adjustable bases can be bulky. Some models may require assembly, while others arrive in one piece. If you think you’ll need help setting your bed up, look for brands that offer services like White Glove delivery. This service includes delivery and assembly, sometimes for an added fee.

Common Problems with a Split King Adjustable Bed

Adjustable split king beds have many benefits, especially for couples. But, like any purchase, they also come with several drawbacks, including cost, size, and certain design features.

Gap and Seam

There may be a noticeable gap in the middle of your split king adjustable bed. Some mattresses may also have a seam on the outer edge. This can be bothersome when it comes to things like cuddling and sex.

There are several ways to minimize this issue. Make sure that the two twin XL mattresses you order with your split king are the same height, and try to find models with smooth top covers and strong edge support. This will make sitting in the middle of your split king more comfortable.

Split King Sheets and Compatible Bed Frames

Even if you already own a king mattress, your current sheets and bed frame may not be compatible with your new split king adjustable bed. Because split kings are made up of two twin XL mattresses placed side by side, it’s best to use two sets of twin XL sheets. This makes it easier to adjust each side of the bed independently.

Adjustable beds usually don’t require a bed frame. However, some brands design their adjustable beds to be compatible with a variety of bed frames. Some models also have mounts for attaching a headboard.


Adjustable bases rely on a motor to move the head and foot of the bed. Some models make noticeable noise when adjusting the bed position. Those who find the noise disruptive should make sure to choose a model with a quiet motor.

Adjustable Frame Weight

Adjustable frames tend to be heavier than standard bed bases of similar size due to their motor and electronic components. Typical adjustable beds weigh around 200 pounds, while split king adjustable beds can weigh closer to 300 pounds, depending on the model.

This can make moving adjustable beds very difficult. Additionally, the combined weight of the adjustable bed base and mattress can place a great deal of stress on the flooring in older homes. However, split adjustable beds are often modular. Being able to separate each half of the bed makes a split king adjustable bed slightly easier to move than a regular king adjustable bed.

Total Cost

A split king adjustable bed will likely be significantly more expensive than a standard king bed, due to its complex construction and added features. You’re also more likely to spend on extras like a new mattress set, sheet set, and headboard. However, the high upfront cost may be worth the investment for some couples. A high-quality, durable model will probably last many years while also providing numerous benefits.
