Best split king size adjustable beds with mattress and frame

It’s 2021 and you’re still sleeping on an uncomfortable mattress that doesn’t fit your needs? You no longer have to! You and your spouse can each have your mattress and still sleep on the same bed! This concept is known as a split king adjustable bed. This article will make you familiar with how this works and how to find the best split king-size adjustable beds with mattresses and frames for you!

What is a split king adjustable bed?

While a regular king-size features one bed and one mattress, a split king has two twin-size mattresses on the same bed. This allows any couple with different sleeping needs to have their own mattress and sheets. Changing positions on one mattress won’t disturb your spouse next to you, thanks to all the in-built mechanical features. Keep in mind that headboards are usually not included with any bases and have to be bought and installed separately if you’re looking for a new one. Take a look at our best picks for the season.

What to look for

It can be difficult to choose the right options with so much variety in the market. But if you’ve made the choice to buy a split king. Here’s a couple of things to keep in mind:

What to look for
Compatibility Quality Comfort
Price Positive customer reviews Decor and design
Features Company policies
  1. Compatibility – If you’ve already got a bed and a mattress that you won’t be discard, you’ll want to ensure the prior setup fits the new split kingframe. Twin size fitted sheets will also need to be bought in case you’ve only got one king-size mattress. It should also be measured to match the frame you are thinking of buying.
  2. Quality – If you’re buying a frame with a mattress included, it is important to check the durability of both since you’ll be discarding your old mattress. Read up on reviews and check up on the extended warranty period to ensure that the one you’re looking at lasts at least 6-7 years. Read up on policies surrounding the electronic features and their repair or replacement in case they malfunction or stop working.
  3. Comfort – After your spouse and you discuss what your sleeping needs are, it’s important to buy a mattress and frame that fits both of your requirements. For instance, if the head and foot incline is important but a massage feature isn’t a must for you, you can go for an option that doesn’t focus so much on the massage points and rather has a comfortable mattress that easily inclines without slipping off the head and foot reclining angles.
  4. Price – Split kings are an expensive investment even in the most basic models due to their high number of electronic features and ergonomic design. Reading reviews and checking ratings will ensure that you buy durable and long-lasting frames that are worth every penny of your hard-earned money.
  5. Decor and design – While frames are highly comfortable, they may not always be the most beautiful. It is a challenge to fit them into a theme-based home. Hence you may have to look into the options of colors and matching sheets to integrate split kings into your decor.
  6. Positive customer reviews – Look for the most appealing stars in the ratings and always check customer feedback to know the plus and minus points of each frame. While one or two problems may be a fluke, a repetitive problem in each review is a red flag and must be avoided at all costs.
  7. Features – Which features do you require the most? A foot-warming feature may be more important to a senior citizen than a USB port. A head-raising anti-snore feature is a must for someone with breathing difficulties and sleep apnea. This is why prioritizing your required features is important before you go and finalize your adjustable base.
  8. Good company policies – If the company guarantees a good period of the extended warranty, it is a good sign of the durability aspect of the frame. Repairs and customer service are also essentials that you can check in the reviews section straight from the customers. Immediate repairs and timely doorstep service are signs of a good company and customer relationship

Problems with this type

There aren’t too many problems with split kings as most are of the same size as regular king-size ones. The few hurdles you can encounter are perhaps buying new fitted sheets for each part. Apart from this, it could be that you find these frames are too big to fit into a small bedroom and hence small spaces aren’t ideal for this type of innovation. Another obstacle is the price aspect. Split kings can be on the pricey side thanks to the premium functions they offer. Especially if they include good quality memory foam mattresses, you’re looking at a budget of at least $3000.

Apart from these minor hurdles, nothing is stopping you from purchasing these superior comfort products.

How do you keep an adjustable split king bed together?

This is a major concern for split king buyers as they wonder how they will ever get used to separate mattresses instead of one big one. But this isn’t a huge a problem as it seems. You simply need two inexpensive pairs of sheet suspenders and lock them into position horizontally from one end to the other. One suspender is locked at the foot of the bed while the second is used to keep the head of the mattresses together. Another measure you can adopt is also to use Otis grip sheets on the wooden surface of the bed, just below the mattress, to make sure it stays skid-free.

Is the split king worth it?

Even though you might have to do some savings or extra stockbroking to get these mattresses, it’s worth the effort because a comfortable night’s sleep is what everyone looks forward to at the end of the day. This mattress can get rid of any unwanted back, hip, and shoulder pains you may experience along with the anti-snore function that tilts your partner to a level they won’t be making much noise at. The various massage intensity levels and the memory foam that has cooling properties take the stress off your muscles as soon as you hit the hay. So yes, we would say it’s is worth every cent.

Can you cuddle on a split king?

Sleeping on different mattresses doesn’t mean you have to stay away from your partner. Simply grab the remote and shift into the same setting as your partner and get cozy! Getting intimate only becomes difficult if you choose to sleep in drastically different settings and positions.

What are the pros and cons?

Of course, before making any big purchase it’s essential you review its pros and cons. Here are the pros and cons of a split king.

  • You and your sleeping partner can customize your side to suit your needs.
  • The double twin options make it easier to move and transport the mattresses whenever and wherever.
  • You can also get different mattresses on each side. For instance a water bed on one side and a memory foam on the other.
  • Motion is not transported from the location of one side to the other. So any amount of tossing and turning by your partner won’t wake you up.
  • Instant massage on days you feel extra stressed.
  • Two and sometimes four USB ports assure you don’t have to leave the bed to charge your phone or even attend an important call.
  • Great lumbar support means no more backaches.
  • Head and foot incline on simply pressing a button on the wireless remote ensures you don’t have to get out of bed to change positions.


  • You will need to buy new sheets of twin size if not already owned.
  • The best models with a higher number of functions are often pricier.

Is two twin XL the same as split king?

A split king size is the same as a normal king-size bed which is measured at 76″ x 80″. One twin XL is measured at 38″ x 80″. This means that two twin XL sized ones combined equal the same as a regular king-size mattress as well as a split king.

Can you put any kind of mattress on an adjustable base?

Yes, usually any mattress fits the bill if you’re adding an adjustable base to your bed. Especially if the mattress was bought in the last five years, it is probably suited for adjustable bases. But you should test out the structural integrity of your mattress to see if it can hold out bending, flexing, and mobility. Common mattresses that fit seamlessly with adjustable bases are memory and latex foams, inner springs, and air beds.

Who has the best prices for these options?

Leggett and Platt are rated as the most value for money brand in adjustable beds by several websites. Not only this, but they also have a separate range of adjustable options under “Value models” so you get the best out of your buck. They offer up to 25 years of extended warranty and have the most range of sizes compared to other brands. Theirs range anywhere from $300 to $3500 which means there’s something to suit everyone’s pocket. This is the reason our top value pick is also Leggett and Platt!

Apart from this, Reverie is also a top manufacturer that offers a wide variety of options. The price range varies from $900- $3200 which means there are budget-friendly options as well as premium luxury items available.

The Sleep number is another top-rated manufacturer that offers a wide variety of adjustable beds with unique features. One of these features that not many others offer is foot-warming to give you a cozy kick start to your sleep. You can customize your mattress to fit your base right on their website according to your budget.

Can most mattresses be used on them?

Yes, most mattresses like memory foams, latex foams, and air beds are suited for adjustable beds. However, older ones and water beds are the types you have to watch out for as they are most likely to lose their structural integrity when bending or flexing the frame.

How much does a king-size adjustable bed cost?

On average a good adjustable bed can cost approximately $3000. However, there are other basic and value models available that can range from $2000- $3000 as well. If you’re only going for adjustable bases without mattresses, your cost can come down by $1000. The higher the number of features and better the mattress, the higher the price you have to pay. But everything is worth it when you experience the unique luxury of sleeping on an adjustable base with your spouse.
