The Best Split King Mattresses – Our Top 9 Picks!

Our Expert’s Take

Saatva is well known for designing luxury-grade mattresses without compromising construction or quality. Its Memory Foam Hybrid offers sleepers the best of both comforting foam and supportive coils in its construction. The mattress is surrounded by high-density rails that keep it strong and retain its edge support, and it has a durable foundation of coils and thick foam. On top are two memory foam comfort layers underneath Saatva’s exclusive “Lumbar Zone Quilting” and a breathable, ultra-soft organic cotton cover.  

The hybrid design and its accessible medium-firmness offer the versatility that makes the Saatva an excellent choice for different types of sleepers who share a mattress. Furthermore, couples can rely on the support of the mattress’s heavy-duty coil and foam base when getting intimate.

Split kings already offer couples more freedom to get a good night’s rest while sharing the bed with their partner. Still, the Saatva takes it one step further by creating a top-to-bottom flexible design that may reliably help different types of sleepers sharing the bed find their unique comfort zone for a night of quality rest beside their significant other.

What We Love About the Saatva Memory Foam Hybrid

• Couples with children or roommates may appreciate that our testers found the bed to stay impressively quiet when they moved around on it. 
• Our tester reported that the mattress had “the best edge support” they have ever encountered. So, expect proper support and comfort across the entire bed’s surface.
• The organic cotton cover and breathable foam design had our tester establishing that the Saatva is “one of the best cooling mattresses on the market.”

What to Keep in Mind About the Saatva Memory Foam Hybrid

• While Saatva does offer a 365-night sleep trial, they will charge a $99 fee for picking up the mattress when making a return.
• Heavier sleepers who sleep on their stomachs may not get the support they need on this Saatva, so they may want to consider a mattress designed specifically for heavy sleepers.

Other user reviews

On the Saatva website, the Memory Foam Hybrid had an average score of 4.8/5 based on at least 171 reviews. Happy customers repeatedly mentioned the balanced combination of sturdy support and plush comfort, making for what many claimed was the “best sleep” a bed can offer.

Our Expert’s Take

With over a dozen different mattress models, Helix Sleep is known for variety. They even created a mattress quiz that matches customers to their ideal bed based on their firmness preferences, sleeping position, and body type.

But if you’re looking for a luxurious medium-firm hybrid mattress, you can’t go wrong with the Helix Midnight Luxe. This mattress contains durable coils, plush foam, and a cooling cover. It works well for most back and side sleepers!

Though you won’t find a split king option on the Helix website, you can purchase two twin XL mattresses and receive the same thing. This makes it a particularly good option for couples with different preferences. That way, each person can rest on the mattress that works for them.

What We Love About the Helix Midnight Luxe

• The Helix Midnight Luxe offers a nice balance of comfort and support, and its perfectly medium-firm feel makes it an ideal choice for most back sleepers.
• As we mentioned, the Helix Midnight Luxe offers a great deal of comfort, especially thanks to its plush pillow-top that gives the bed a hotel mattress feel.
• It’s a great choice for hot sleepers since it’s made to help dissipate heat. The layer of coils in the mattress help promote airflow, and the cover and foams on the mattress are designed to promote cooling and breathability. 

What to Keep in Mind About the Helix Midnight Luxe

• Again, the Midnight Luxe is perfectly medium-firm, so it likely won’t be supportive enough for stomach sleepers, who will likely want something firmer, like the Helix Dawn Luxe.
• As the name suggests, the Helix Midnight Luxe is a luxurious mattress and comes at a luxurious price tag. If you’re on a budget, this may not be a great fit.

Other user reviews

Over 5,000 customers rated the Helix Midnight Luxe on the Helix site and gave it an average score of 4.4 out of 5 stars. Reviewers loved that the mattress is soft and comfortable, but still feels supportive enough to hold up their bodies properly. On the other hand, some users felt the opposite and thought that the mattress was too soft.

Our Expert’s Take

Hybrid mattresses are a great solution if you want the durability and support of an innerspring bed and the ultra-comfort of a foam-based bed in one. The DreamCloud Original is a five-layered hybrid that combines foam and coils in its construction to efficiently deliver the benefits of both materials. At its base is a combination of coils for extra support and airflow underneath a high-density foam layer. At its core is a foam transition layer designed to retain comfort while preventing too much sinkage into the bed when sleeping. And greeting you on top is a pressure-relieving gel memory foam layer and a luxurious cashmere-blend cover top. The construction allows you to embrace memory foam’s hug while helping you avoid sleeping hot or compromising posture support when resting.

While the cashmere cover and memory gel top layers have a snug feel, the mattress is firmer than typical all-foam beds (7.5/10), making it ideal for people with back pain who love all-foam beds but don’t get the lumbar support they need. Overall, the DreamCloud is a great option for combination sleepers and couples with different sleeping preferences, making it one of the more stand-out luxury hybrid mattresses today.

What We Love About the DreamCloud Original

• The quilted cashmere and foam blend cover top offers ultra comfort without compromising airflow. Testers found it to be “breathable and soft to the touch.”
• The bed is built to last, with testers estimating you’ll get a quality six to eight years of proper rest on the DreamCloud.
• The firmness and design of this hybrid provide great pressure relief for people with back pain.

What to Keep in Mind About the DreamCloud Original

• Heavier sleepers (over 230 lb) may want to look elsewhere, especially those who sleep on their stomach or side. Our heavier tester reported tension from sinking into the firmer layers when resting on their stomach or side.
• Due to the Dreamcloud’s size and weight, home setup may be complicated. And in-home setup comes at an additional $200.

Other user reviews

Out of 5125 reviews on DreamCloud’s website, their Original hybrid impressively kept an average score of 4.5/5. Many reported quality back support, with one review describing the hybrid design as “the right combination of support and comfort.”

Our Expert’s Take

One reason to get a split king may be that one partner requires more support than the other. For example: What feels firm to a heavyweight sleeper might feel overly smushy to a lightweight sleeper. And there are few mattresses on the market that do a better job providing solid support than the Nolah Evolution, the most luxury mattress from the Nolah brand. Its hybrid build is made to support people of all sizes without sagging or breaking down too quickly or easily.

Plus, if you’re particular about your firmness preference, you can choose among Plush, Luxury Firm and Firm models of the bed. Our testers were most inclined to try the middle ground Luxury Firm model, which clocked a 6.5/10 on our firmness scale.

What We Love About the Nolah Evolution

• The Nolah Evolution is an exceptionally durable mattress that should least at least 10 years, likely more. That makes it a great purchase for eco-conscious consumers who want to avoid filling up landfills with mattress after mattress.
• The bounciness of the Nolah Evolution means it might be the ideal side of the split king during sex: Couples looking for the best mattress for sex can seamlessly switch positions without feeling stuck. 
• The Nolah Evolution mattress is made with a breathable cover and coils that promote airflow, making it one of the coolest mattress on the market, so it shouldn’t cause hot sleepers to overheat at night.

What to Keep in Mind About the Nolah Evolution

• The edge support on the Nolah Evolution is less robust than that of hybrids with a double coil layer. If you tend to stray from the center of your bed and don’t want to feel like you’re about to roll off, try the WinkBed or Saatva Original.
• The pricetag on the Nolah Evolution is a bit steeper, even for a hybrid. A twin XL has a $1,599 sticker price ($1,099 with sales at publishing time).

Other user reviews

The Nolah website is less transparent with its customer reviews than that of other sites, so we can’t state the number of reviews in the 1- to 5-star range for the Evolution — only that the average is 4.9 out of 5. We also couldn’t sort reviews to find the opinion of sleepers on  split kings, but most of the featured recent reviews for the bed are positive, sighting the bed’s comfort.

Our Expert’s Take

The Bear Elite Hybrid mattress is a quality mattress made with athletes in mind and catered to their need to rest and recharge after a workout. The mattress comes in three firmness levels, and the medium-firm model is great for most back and side sleepers.

The Bear Elite Hybrid is one of the company’s most luxurious models, and its cooling features are some of its most impressive features. The mattress has a celliant cover, which is designed to help you keep cool, and furthermore, the top layer is infused with copper to help draw heat away from the body.

What We Love About the Bear Elite Hybrid

• The Bear Elite Hybrid has a great balance of comfort and support. The thick comfort layers are great for pressure relief, while the layer of coils helps to add support.
• The Elite Hybrid comes in three firmness levels, Soft, Medium, and Firm. We tested the Medium version and thinks its a great match for side and back sleepers because of it’s balanced foam feel.
• The mattress is cooling and made with a cooling cover and coils that help promote airflow. This makes it a great fit for people who sleep hot.

What to Keep in Mind About the Bear Elite Hybrid

• Since this mattress is made with coil layers, it’s a bouncy and responsive mattress. If you prefer a slow-moving mattress, try one of the all-foam mattresses in this roundup, such as the Nectar Premier.
• The Elite Hybrid is Bear’s most luxurious mattress. It’s made with high-quality materials, which means that it’s not a great mattress for shoppers who are on a budget.

Other user reviews

The Bear Elite Hybrid has a customer rating of 4.3 out of 5 stars on the Bear website. Some of the top reviews praised the mattress for its cooling effects, its comfortableness, and how plush it felt. As far as negative reviews go, some users complained that the mattress began to sag not too long after they began using it.

Our Expert’s Take

The Brooklyn Bedding Aurora Luxe mattress is available in three firmness levels: soft, medium, and firm. Average weight back sleepers, however, will feel the most comfort and support on the medium model.

This mattress features premium memory foam, high-quality transition foam, and 8” of individually-encased coils. All together, these materials give the mattress a long lifespan of 7-10 years – but that doesn’t mean it’ll cost an arm and a leg! Brooklyn Bedding owns their own factory, so they can cut costs and pass the savings on to customers.

What We Love About the Brooklyn Bedding Aurora Luxe 

• The Brooklyn Bedding Aurora Luxe should be a great choice for hot sleepers, thanks to its gel-infused foam layers and breathable cover.
• It offers a nice balance of comfort and support thanks to it’s soft foams and coil layers. This makes it a good fit for back sleepers.
• If you are a combination sleeper, or are looking for the best mattress for sex, this mattress may be a good fit since it’s easy to move around on.

What to Keep in Mind About the Brooklyn Bedding Aurora Luxe 

• Stomach sleepers need a firm mattress that’ll keep their spines aligned while they sleep. We tested the Medium version of the Brooklyn Bedding Aurora Luxe, which is too soft for stomach sleepers.
• Much like stomach sleepers, heavy people also tend to need firmer mattresses to get the needed support, and this mattress likely won’t offer that.

Other user reviews

On the Brooklyn Bedding website, the Aurora Luxe mattress is rated 4.7 out of 5 stars by customers. Reviewers think that the mattress is comfortable and keeps them from tossing and turning throughout the night, while some negative reviews noted the exact opposite – the mattress wasn’t comfortable enough.

Our Expert’s Take

If you’re a heavyweight sleeper, firmness is one of the most important factors to consider when shopping for a mattress. We rated the Titan Plus a 9 out of 10 on our firmness scale, meaning it’s really firm. This isn’t going to be a great option for everyone, but we do feel it accommodates most heavyweight sleepers very well. 

In addition to providing needed support and firmness for heavyweight sleepers, the Titan Plus also does a great job of staying cool throughout the night. Like most hybrids, the Titan’s layer of coils allows your body heat to easily flow out of the mattress—this breathability can help keep things from heating up to an uncomfortable temperature.

What We Love About the Titan Plus

• The Titan Plus is a great mattress for heavy people. It’s on the firmer side, so it’s supportive enough for people who weigh 230 to 500 lbs.
• Since it’s a firm mattress, people who sleep on their stomachs may also get some really decent support from this mattress.
• There are a few mattresses for heavy people on the market, but the Titan Plus is a more budget-friendly option for these kinds of mattresses. 

What to Keep in Mind About the Titan Plus

• Though this is a great mattress for heavy people, heavy side sleepers may not get the best pressure relief in the hips and shoulders and may want to opt for the Luxe version of this mattress instead.
• Because this is a mattress meant specifically for heavy sleepers, people who weigh less than 230 lbs will probably think that this mattress is too firm.

Other user reviews

The Titan mattress scores pretty highly on the Brooklyn Bedding website, as customers rated the mattress 4.7 out of 5 stars. The mattress is specifically made to support heavier bodies, and customers who fit the bill praised how supportive this mattress felt, regardless of their sleeping position.

Our Expert’s Take

Birch, also created by Helix Sleep, is one of the best eco-friendly mattresses on the market. Made with durable Talalay latex, organic cotton, and strong innersprings, this bed is both cooling and luxurious.

Another perk: Talalay latex is naturally breathable, so it won’t trap heat like memory foam often does. This material also feels responsive, making it easy for folks to move around on top of the mattress.

The Birch mattress feels slightly firmer than the industry standard, coming in at 7/10 on our firmness scale. We recommend this mattress for back sleepers and lightweight stomach sleepers.

What We Love About the Birch

• The Birch is an eco-friendly and organic mattress that features all-natural, fair-trade textiles without harmful chemicals or pollutants. It also has a cover that is made with Global Organic Textile Standard (GOTS) certified organic cotton, organic wool, and eco-INSTITUT certified Talalay latex.
• The organic materials such as cotton, wool, and ventilated latex help make the Birch mattress a more breathable mattress than typical memory foam mattresses, which may make it a good fit for hot sleepers. 

What to Keep in Mind About the Birch

• The bouncy nature of the Birch mattress makes for some high motion transfer. If you sleep with a partner who is easily disturbed by movements, this is something to consider.
• The Birch is firmer than average, so side sleepers may feel some pressure on their hips and shoulders while lying on this mattress.

Other user reviews

On the Birch website, the Birch mattress is given an average customer rating of 4.7 out of 5 stars. Some of the highest praise comes from customers who think that the mattress is comfortable and easy to set up, and who love the eco-friendly materials. The few negative reviews mostly are complaints about the thinness of the latex layer.
