Split king adjustable beds are possibly the best way to share a bed without sharing a bed. They allow you to set your own sleep position and choose your own mattress without impacting your partner.

They can also help alleviate snoring and reduce motion transfer. So if sleeping with your partner means you’re not actually sleeping, read on.

“While it’s important to get regular exercise and consult with a physical therapist when needed, sleep is also extremely important,” says Jennifer Miller, a noted physical therapist. “Many of my patients have back pain and I make sure to inquire about their sleeping position, use of pillows, and mattress type.”

“We spend much of our time sleeping and poor quality mattresses or a snoring spouse can reduce the quality of sleep and overall health. I encourage my patients to look into an adjustable bed when repositioning with pillows isn’t enough, especially when they have sleep apnea or swelling in their legs.”

We’ll talk about some of the best adjustable beds on the market and all the ways they can offer you relief from the complications of sharing a bed with another person.

How to Choose the Right Adjustable Bed for You

You and your partner are probably looking at a split king size mattress and bed because you have divergent sleep needs. The good news is that most adjustable bed bases are equipped to meet almost everyone’s needs. So it shouldn’t be too hard for you and your partner to find a compromise that suits you both.

Bed Articulation

The articulation of an adjustable bed is the number of degrees it can rise up on each end. The zero-gravity position is between 30 and 45 degrees for both your head and feet. So if you want a bed that lets you sleep in this position, you’ll need at least 45 degrees of articulation.

Those who want to sit fully up in bed for reading or watching TV (though this isn’t the best sleep hygiene practice) should make sure they’re getting an adjustable base that can go all the way up to 60 degrees at the head. It’s one of the simpler benefits of an adjustable bed.

Bed Height

Those who want an adjustable base for pain or mobility issues should seriously consider their bed height. You’ll want a bed profile that is around the same height as a couch or chair. That is to say, when you’re sitting on the edge of the bed, your feet comfortably touch the floor.

The good news is most adjustable beds now come with adjustable height. This is usually done using incremental legs. The more leg pieces you stack together, the higher the bed’s height. This is perfect for anyone seeking an adjustable bed for seniors or anyone else who needs to slide out of bed with minimal risk of falling down.

As a reminder, your bed height consists of your frame or foundation, plus your mattress thickness and any thick toppers or pads you have.

Ease of Assembly

If you’re handy, this may not be an issue for you. But for those of us who aren’t so great with the toolbox, a bed’s ease of assembly can be a major factor in the decision-making process. Thankfully, many adjustable beds can now be snapped together with a few quick steps and few to no tools. Even optional steps like attaching a headboard to an adjustable bed can be relatively hassle-free.

If an adjustable bed has easy assembly, that fact is typically prominently displayed. Some beds might offer free in-room setup in lieu of easy assembly. Again, if this is something you’re looking for, manufacturers often advertise it prominently.


It’s no secret adjustable bed frames are not cheap. They’re quite a bit more expensive than standard immobile bed frames, and split king ones are usually the most expensive of the adjustable lineup. So expect to pay well over $1,000 for your setup. You may be paying much more than that, depending on the brand and features of your adjustable bed.

Special Features

Special features are additional features that are not necessary for the operation of the bed but make sleeping on it a more luxurious experience. These include massagers, underbed lighting, USB ports, wireless connectivity, and more.

Keep in mind these features can have a huge impact on the bed’s price. So if you want to keep it affordable, you might consider base models that don’t have the bells and whistles.

Weight Capacity

Your bed’s maximum weight is a big factor to consider, especially if you or your mattress are on the heavier side. When it comes to split kings, each side of the bed will have its own max weight because it’s technically its own separate bed. You’ll need to know your and your mattress’s weight so that you can stay well within the parameters of your adjustable base.

Mattresses Compatible with an Adjustable Base

When it comes to mattresses for adjustable bases, we’ve got bad news and good news. The bad news is that one of the most popular mattress types, traditional innerspring, cannot be used with an adjustable base.

Innerspring mattresses feature a support core of open coils. These coils are wired together in a network that spans the entire bed. This means innerspring mattresses are stiff and cannot bend with an adjustable base.

At worst, they will break the adjustable bed or break themselves when you try to move it out of the flat position. At best, they will “float” above the lower parts of the adjustable bed because they cannot flex with it.

The good news, though, is that (for the most part) every other popular mattress type is compatible with an adjustable bed. So those with an innerspring mattress will need to replace it, but if you have a foam or hybrid mattress, you’re good to go!

Memory Foam

Of all the mattress types on the market, memory foam is the best for adjustable beds. This is because of its combination of comparatively lighter weight, decent durability, and excellent flexibility. A memory foam mattress wants to mold itself to the shape of anything that can exert pressure on it. That means it can flex with an adjustable bed in a way that no other mattress type can.

Memory foam mattresses are also usually lighter than hybrid or latex mattresses. So you will almost never have to worry about the mattress being too heavy for the bed. While memory foam is not as durable as latex, it is still more than durable enough to withstand night after night of being bent and unbent.

The only sleepers who might not like memory foam are hot sleepers and active sleepers. This is because memory foam is not all that great at regulating its temperature, though there are cooling mattresses for hot sleepers. It’s also the least responsive of all the mattress types that can be laid on an adjustable base.

If you have any more questions, read our memory foam mattress buying guide.

Natural Latex

Natural latex is made from the sap of the rubber tree, and it’s a fantastic answer for those who want an all-foam mattress but don’t want to deal with memory foam’s temperature and responsiveness issues. For a thorough comparison of the two materials, see our memory foam vs latex mattress guide.

Latex mattresses are airy and breathable. It’s springy and responsive. And it’s flexible enough to bend with an adjustable base. It’s also the most durable of all mattress types, meaning it can be bent out of shape night after night without wearing out.

Latex’s weight is the main reason it is not quite as good an option for adjustable bases. Natural latex is a very heavy foam. So when you purchase a latex mattress, you’ll need to pay close attention to the weight of the mattress to make sure it can combine with your weight and still remain under the adjustable bed’s maximum capacity.

For more information, read our latex mattress buying guide.


Hybrid mattresses are virtually the only option available to you if you want both springs and an adjustable base. Hybrids have an internal support core made of pocketed coils. These individually wrapped coils are not wired together. So they can flex with an adjustable bed in a way that innerspring coils cannot.

Hybrids are another excellent choice for those who want a lot of bounce and breathability. Their coils allow for tons of air circulation, and they spring back into place without transferring motion the way that innerspring coils do.

Watch out, though. Not all hybrid mattresses are intended for adjustable bases. Most are, but some have internal coils setups that can be rearranged or otherwise harmed by the flexing of the bed. So before you purchase a hybrid for an adjustable base, make sure it is intended to go on one. Most manufacturers will list bases appropriate for their mattresses on their websites.

Saving on Adjustable Beds


Can I use a single king size mattress on an adjustable split king bed?

You can definitely use a single king mattress on a split king adjustable bed. You’ll just need to make sure whatever split king adjustable base you buy has an autosync feature. Autosync allows the two twin XL adjustable bases in your king bed to move as a single unit.

This is extremely important. If the two sides of your bed move independently underneath a single king mattress, this could destroy it. The support underneath the mattress needs to be even from edge to edge, and the mattress also needs to bend the same way from edge to edge.

Anything else can cause tearing or stretching of the mattress’s internal structure that can lead to sagging and soft spots.

How is the adjustable bed’s weight capacity measured, by one person on one twin XL or two people on the whole split king bed?

When putting a split king bed together, you’ll want to think of each side of the bed as its own entity. For example, if each side of your bed has a maximum weight capacity of 400 pounds, that means you can put 400 pounds of mattress and sleeper on each side of the bed.

Technically, this means your bed can take 800 pounds altogether. However, that 800 pounds needs to be somewhat evenly distributed across both sides of the bed, and neither side should exceed 400 pounds. The good news is twin XL mattresses are typically not all that heavy and should not exceed your side of the bed’s capacity.

Do I need separate sheets for a split king adjustable bed?

That depends on a couple of different factors. If you’re going to autosync your adjustable split king bed and put a single king size mattress on it, you can just get a set of standard king sheets and be done with it. A king size topper can even hide the gap between the two twin XL mattresses.

If you’re going to do a true split king adjustable bed, things can get more complicated. You’ll definitely need two twin XL fitted sheets, one for each mattress. Depending on your expected adjustable bed settings, you may also need separate flat sheets and blankets.

For instance, if you both are going to sleep in similar positions with only slight variations, you can probably get away with a single flat sheet and comforter. But if you’re going to have highly divergent adjustable base positions, you might need to consider two entirely separate bedding sets.

Will a split king stop my partner’s snoring?

A split king can absolutely help keep your partner quiet at night. When you sleep, the muscles in your throat relax, allowing your soft tissues to rattle around inside your airways. This is the mechanism that causes snoring. Elevating the head can allow gravity to hold the soft tissues in the throat in place. This can reduce or even eliminate snoring entirely.

Keep in mind that an adjustable bed alone may not be sufficient if your partner’s snoring issue is actually caused by obstructive sleep apnea. If the snoring is extremely loud, or if breathing regularly ceases during sleep, it’s best to see a sleep specialist.

Do two twin size mattresses make a split king bed?

No. 38 by 75-inch twin size mattresses are wide enough to make a standard king size bed when you put them side by side, but they’re too short. Twin XL mattresses are the size you need to make a king size bed.

These mattresses are still 38 inches wide, but at 80 inches long, they’re long enough to fit perfectly into a standard king size bed frame. So when you’re shopping for split king mattresses, remember to get a twin XL, not a twin.

Bottom Line

Adjustable split king beds can help you get a great night’s sleep with your partner by your side. They can do everything from reducing snoring to allowing for different sleep positions. That makes them the perfect way to share a bed without sharing a bed!
