I can personally vouch for the comfort factor as I have one myself and I love to raise the head to read in bed.

In this article, I’ll take you through what I think are the top 3 split king adjustable bases you can buy, and there’s also a bonus section on a smart base. I’ll tell you right now that Saatva is one of the only brands offering a split California King so if you’re looking for one of those, head straight to them.

Top 3 Picks For Split King Adjustable Bed Bases

After spending a LOT of time picking through your buying options, I’ve landed on these as my top three. All of them have head and foot articulation, under-bed lighting, massage functions, and remotes with presets.

They’ve got everything you need to make using your adjustable bed the comfortable and easy experience it should be.

1. Best Overall: Saatva Plus Adjustable Bed Base

First of all, I really like Saatva as a brand. They make good quality products and pride themselves on their excellent service. For the purposes of this review, we’re talking about the “standard” adjustable base, not the “upper flex” model.

• Made in the USA
• Free white glove delivery (this means they come and set it up in your house for you, this is awesome)
• 25 Year warranty
• Many size options, including Split King AND Split California King
• Legs: Push pin legs are adjustable from 8″ to 13” for a total height of 13”-18” in 0.5” increments
• Weight capacity: 850lb total
• USB Ports: none (this is the one small negative of this split king base)
• Massage function: wave, head, or leg. 15 minute timer
• Clear plastic corners at the bottom edges to help hold your mattress in place

It’s also important to note that if you want Saatva mattresses to pair with your base, their mattresses are one of the few online-only mattress brands that are not mattresses in boxes, and they are superb quality. I recommend the 11.5-inch height Saatva mattress to pair with this base.

2. Best Value: Puffy Adjustable Base

Best known for their massively popular and feature-packed memory foam mattress range, Puffy also make an incredible adjustable bed base which is the best value of any in this article. It’s also the only one offering you a 101 night sleep trial, so your purchase is completely risk-free. What a bargain.

• 101 Night sleep trial
• Free shipping, and will arrive within 1-3 business days
• Unbeatable lifetime warranty
• Legs: 3 adjustable height settings: 6.5, 9.5 or 11.5 inches
• Dual USB charging ports
• Massage function: 3 speeds, two zones
• Metal bar at the bottom to hold your mattress(es) in place
• Make the most of Puffy’s current discount deal: save $300 on your purchase AND get up to $455 worth of free accessories when you buy a bundle including Puffy’s awesome mattress

I had a read through the reviews of this base as the combination of powerful features, big sleep trial, and value price all seem too good to be true. I’m happy to reassure you that this is a legitimate great deal, and I could only find people raving about how great this base is, how sturdy it is, and how well it performs. This is an all-around great buy.

3. Best Massage Power: GhostBed Adjustable Bed

I actually love the GhostBed base. The whisper-quiet massage functions are amazing, and it comes with all the features you’d expect. It’s a shame it doesn’t come with in home setup or a sleep trial, but honestly, these bases are easy to put together and I strongly doubt you’ll want to return this base anyway.

• Fast delivery: ships within 24 hours!
• Designed and engineered in the USA
• Dual massage (that means at both head and feet ends) with 15 settings, bliss
• Legs: adjustable height to suit your preferences and your mattresses
• Zero gravity, massage, and 3 preset options
• USB Ports and night lights
• A black bar at the bottom edge to hold your mattress in place

GhostBed also often run really amazing sale deals, and my links will take you straight to today’s best price. I think that in my 4+ years of reviewing and testing beds, they offer some of the deepest discounts on adjustable bases that I’ve EVER seen.

Honorable Mention: Emma Powerbase Pro Adjustable Bed

I own two Emma mattresses and an Emma bed frame, so I can personally vouch for the quality of their products. This adjustable base is the only one with voice activation, which really makes it stand out (no more worries about lost remotes!)

Emma sells this base in twin XL, Queen, and King sizes. To make your spit king adjustable bed you simply purchase two twin XL bases, as this is what a split king-size bed is.

• Free delivery with a simple setup: you unfold the base and attach the legs yourself
• 10 Year warranty and 24/7 customer support
• Size options: Twin XL (buy two to make your split king), Queen, King
• Legs: 12 legs, adjustable height to suit your preferences and your mattresses
• Zero gravity, massage, and 3 preset options
• USB Ports and night lights
• Voice control command options this is the only base I’ve seen this on!
• A black bar at the bottom edge to hold your mattress in place

BONUS : The Best Smart Base Is The TEMPUR-Ergo Smart Base

If you want a base that goes above and beyond by giving you insights into your sleep quality, sleep analytics, and programmable sleep alarms, then the TEMPUR -Ergo smart base is the best split king adjustable base for you. Simply download the app to your phone, and get all the benefits of the bases above, plus the intelligence of automatic head raising in response to snoring, a breakdown of your sleep time and quality, and so much more.

• Free white glove delivery (this means they come and set it up in your house for you, like Saatva)
• 25 Year warranty
• Many size options, including Split King AND Split California King
• Legs: 12″ stackable legs that can be set at 3″, 6″, 9″, or 12″ depending on your preference.
• Weight capacity: 700lb
• USB Ports: 4
• Massage function: 3 intensity levels across 2 zones of the base or 4 (2 zones = one at the head and one at the feet 4 = two zones at the head, and two at the feet)
• A black bar at the bottom edge to hold your mattress in place

This base is compatible with other smart gadgets you might have in your home: get your sleep info from your smart base via Hey Google or Alexa!

Why not the TEMPUR-Ergo extend base? I don’t think the extra features are worth the extra $1000. Save your money and just get the regular one.

What Makes The Saatva Plus Base Really Stand Out As #1?

In One Sentence: it offers the most features for your money but also has the lowest recommended retail price.

Here’s a full list. There are a lot of reasons!

• It’s the only one in this roundup that’s made in the USA
• It comes with free in-home set-up (I speak from experience assembling an adjustable base myself: they are HEAVY and difficult to maneuver. You’ll really appreciate this.
• It has the most customizable leg height options
• It’s known to have very quiet motors
• It has a high weight capacity
• It has the lowest recommended retail price. The only thing missing here is USB ports. My base doesn’t have them either, and I can’t say I feel like I’m missing out so I do not think this is a big deal.

Key Features to Consider While Buying Split King Adjustable Bed Base

When you’re choosing your adjustable base, you’ll need to understand how it moves, and whether your mattress is compatible with it.

You’ll also want to understand exactly what features you can access with a touch of your remote, and the quality of your base.

Adjustability Options and Range of Motion

With motors on each side of the bed you can choose to adjust one side separately from the other, or synch the sides together so the bed moves as one.

A good adjustable bed will have a range of height adjustments from flat to nearly 90 degrees at the head, and a smaller range of motion at the feet (you don’t need your legs sticking right up in the air).

This means you can adjust the bed into pretty much any position you desire. My personal favorite is back almost straight up and feet elevated a bit for reading.

Mattress Compatibility and Support System

You will find that most modern mattresses are compatible with an adjustable bed frame, as they are more flexible than traditional innersprung mattresses.

To operate a split king base independently on each side, you will need two twin xl mattresses to fit the frame.

This is especially true for all foam mattresses, as the foams flex easily as you adjust the bed. Many pocket coil mattresses are also compatible with an adjustable bed base but please do check first as you do not want to void any warranty.

All of the bases I have talked about in this review can be made into great value bundles with mattresses, so you can get a whole new bed in one go if that is easier for you.

If you really want to feel the massage features of your adjustable base, I recommend you get a thinner mattress. I use a 14 inch mattress on mine and it’s a bit too thick to really feel the massage through.

Remote Control and Customizable Settings

That’s my remote pictured above. Yours will look similar. You can see it’s quite a small remote that packs a lot of features.

At the top you can see buttons for pairing bases, locking the base, memory, and light. Then you’ve got handy presets like zero gravity, reading, and flat. You can see there are buttons so you can adjust the angle of the head and/or foot exactly as you wish.

At the bottom, you have your massage settings.

Your remote may have a different configuration but these are the buttons you can expect to see on an adjustable bed base with the full range of features.

Durability and Quality of Construction

Adjustable beds are really sturdy. The’ve generally got steel or solid wood cores that are built to last, and a soft but wear-resistant fabric cover for your mattress to sit on.

The motors are designed to be quiet and powerful, and should last for ten years. Most brands will offer 5 – 10 year warranties with their adjustable bed bases. I’ve had mine for more than a year now and it’s still looking and working like new.

Best Split King Adjustable Bed Base FAQ

• Is a Split King adjustable bed base worth it?
  • It’s an easy yes from me. Not only are they are sturdy and strong base that will support your mattress really well, they will bring you many benefits as listed above. They generally cost $1000-$3000: I’ve certainly seen bed bases in this price range that don’t perform nearly as well as any of these 3 adjustable bases do.
• Is a Split King the same as two Twins?
  • A Split King adjustable bed base is the equivalent of two Twin XL bases.
• What sheets do I use with my Split King adjustable bed base?
  • For the base, you’ll need two Twin XL size fitted sheets. If you also like top sheets, you then have the option of one king sheet to cover the entire bed or separate Twin XL size flat sheets. Look for brands like ever popular Brooklinen, who offer special Split King sheet sets.
• Is a Split King bigger than a King?
  • No. The dimensions should be very similar, but you may find small variations from brand to brand. Each of the brands I recommend in this article have their dimensions on their websites.
• Do adjustable beds ruin mattresses?
  • Nope! In fact, many modern mattresses are designed to work perfectly with an adjustable base, especially memory foam and latex mattresses. If you’re in doubt, please check with your manufacturer. One small thing: I generally recommend a mattress height of up to 12 inches for an adjustable bed base, which is why I suggest you buy the Saatva 11.5 inch mattress instead of the 14.5 inch mattress for use with their Split King adjustable bed base.
• Do I still need to use a foundation or box spring?
  • Nope! Your adjustable bed base works as a support for your mattress all on its own. However, if you like the look of a bedhead or frame, most adjustable bases will fit inside any open cavity frame or are compatible with a range of bed heads. Again, just make sure you check those measurements first!

Conclusion

Now you know everything you need to know about split king adjustable beds. Getting a bed that’s of high quality and a good range of features is really important for you to get the most out of your purchase.
