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 couples with different sleeping needs to have their mattress and sheets. Changing positions on one mattress won’t disturb your spouse next to you, thanks to all the in-built mechanical features. Remember that headboards are usually not included with any bases and have to be bought and installed separately. 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 chosen to buy a split king. Here are a couple of things to keep in mind:

What to look for
PricePositive customer reviewsDecor and design
FeaturesCompany policies 
  1. Compatibility – You’ve already got a bed and a mattress that you won’t be discarding. You’ll want to ensure the prior setup fits the new split king frame. 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. You’ll discard your old mattress unless you store it somewhere. Read up on reviews and check up on the extended warranty period. 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. It’s good in case they malfunction or stop working.
  3. Comfort – After your spouse and you discuss your sleeping needs, buying a mattress and frame that fits your requirements is important. The head and foot incline may be 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. Rather, find one that has a comfortable mattress that easily inclines without slipping off the head and foot reclining angles.
  4. Price – Split kings are expensive, even in the most basic models. It is due to their high number of electronic features and ergonomic design. Reading reviews will ensure that you buy durable, long-lasting frames 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. Always check customer feedback to know the plus and minus points of each frame. 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

split king size adjustable beds with mattress and frame

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 buying new fitted bed sheets for each part. Apart from this, it could be that you find these frames too big to fit into a small bedroom. 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 stops you from purchasing these superior comfort products.

Is a split king worth it?

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 eliminate any unwanted back and shoulder pains you may experience. It has an anti-snore function that tilts your partner to a level they won’t be making much noise. The massage levels and the memory foam with cooling properties take the stress off your muscles as you hit the hay. So yes, we would say it’s worth every cent.

Can you cuddle on a split king?

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

Do they make a split king adjustable bed?

Yes, and it’s amazing. It will allow two people with very individual sleeping needs to get that quality sleep you’ve been hoping for.

Is two twin XL the same as split king?

A split king size is the same as a normal king-size bed 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.

Why would you want a split king bed?

People have very individual sleep needs, and this product is great for that purpose.

How do you keep an adjustable split king bed together?

This is a major concern for split king buyers. They wonder how they will ever get used to separate mattresses instead of one big one. But this isn’t as huge a problem as it seems. You need two inexpensive pairs of sheet suspenders. 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 to use Otis grip sheets on the wooden surface of the bed below the mattress. Make sure it stays skid-free.

What kind of sheets do you use on a split king adjustable bed?

2 twin fitted sheets. On top of it, you’ll usually put a flat sheet for a king-size. We promise you the hassle will be worth it!

What are the pros and cons?

  • The best models with a higher number of functions are often pricier.

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. 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. See if it can hold out bending and flexing. Standard mattresses that fit seamlessly with adjustable bases are memory and latex foams. You can also use inner springs and air beds.

couple lying on a split king mattress

Yes, most mattresses can. Your memory foams or latex foams are suited for adjustable beds. However, older ones and water beds are the types you have to watch out for. 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 to $3000. 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.

How to keep sheets on an adjustable bed

  1. Find the right bed sheets
