The Best Split King Mattresses To Customize Each Side Of The Bed

For many people, sleeping next to someone is comforting and can even reduce anxiety or help them fall asleep faster. But what happens when opposites genuinely attract and your mattress needs don’t align? That’s where the best split king mattresses can come into play. They allow you to pick your own firmness and feel for your side of the bed while also minimizing motion transfer.

The best split king mattresses cater to a couple's individual needs. According to Dr. Nathan Holley, a chiropractor with more than 12 years of experience in clinical practice, snoozing on a mattress better suited for your partner can have real consequences. “Not having the firmness your body requires can show up in many ways,” says Dr.

Holley. “In addition to causing pressure point and alignment issues with the spine, circulatory, respiratory and muscle problems can also form when a mattress doesn’t suit the person.” Luckily, you don’t have to compromise. Split king mattresses consist of two twin XL beds that sit together to form the equivalent of a king size mattress .

While this offers all the space of a bigger bed, it allows each side to have a different comfort level to suit individual needs. See our top picks below for the best split king mattress for every couple. Best Split King Mattress Overall Nectar Type : Memory foam or hybrid | Firmness : Medium firm | Delivery : Bed in a box | Trial : 365 nights | Warranty : Lifetime Thanks to its versatility, the Nectar Premier Copper is our top overall pick for the best split king mattress.

Because it’s available in both memory foam and hybrid versions, this model is suitable for most sleeping positions. We recommend the hybrid option for back and combination sleepers who require more support and responsiveness and the foam model for side sleepers who want deeper sinkage. Nectar rates it at a 6.5 comfort level and calls it medium firm, which is where comfort and support collide.

Seven layers comprise the hybrid version, including 4 inches of foam to contour your curves and relieve pressure. The coils are individually wrapped and respond to your movements with minimal motion transfer. Together, the foam and springs promote proper spinal alignment. The memory foam model is designed with several layers of foam that work in tandem to offer support while allowing crucial rebound.

A cooling cover featuring copper fibers intended to dispel the heat and excess moisture tops both options. What’s more, both models are made with CertiPUR US certified foams. What our editors say: “I found the Nectar Premier Copper all foam model to have a very classic memory foam feel with slow, deep sinkage,” says senior mattress and sleep editor Bridget Chapman.

“There are mattresses out there with similar feels that cost a lot more money. However, I do think it’s firmer than advertised and would consider it a firm bed (rather than medium firm).” Best Value Split King Mattress Leesa Type : Foam | Firmness : Medium firm | Delivery : Bed in a box | Trial : 100 nights | Warranty : 10 years As the overall pick for our list of best affordable mattresses , the Leesa Studio is a top contender for anyone looking for a budget friendly split king mattress that doesn’t sacrifice quality.

While it doesn’t have a specific split king option, buyers can choose two twin XL mattresses with a medium firm feel. Plus, you don’t have to worry about that disagreeable off gassing smell many foam beds have because it’s Greenguard Gold certified and meets the strictest guidelines for VOC emissions.

This mattress is designed with three distinct foam layers. The base layer offers stability and support, the comfort layer contains billions of micro air capsules to help cool you down and the responsive memory foam contours for better alignment. It’s topped with a cover designed for both comfort and cooling.

Together, the different types of foam combine to offer cradling support in nearly any position and relieve hip and shoulder pressure. While this mattress is competitively priced, it’s made with quality CertiPUR US certified foam that ensures it doesn’t contain ozone depleters, flame retardants, formaldehyde and other harmful substances.

What our editors say: “For folks looking for a firm, affordable memory foam option that doesn’t let you sink in too much, this is a great choice,” says Forbes Vetted contributor Lindsey Vickers. She says since it allows you to sink slightly into the mattress to cradle you, it also offers excellent pressure relief.

As a stomach sleeper, Vickers says she’d consider purchasing the Leesa Studio. Best Split King Mattress For Back Pain Saatva Type : Hybrid | Firmness : Plush soft, luxury firm and firm | Delivery : Free white glove delivery | Trial : 365 nights | Warranty : Lifetime With a combination of memory foam, spinal wire and responsive coils, the Saatva Classic is engineered specifically to offer relief for achy backs and joints.

Sitting at the base of the mattress are tempered steel coils surrounded by foam rails to help prevent sagging and create a stable edge. Above that are pocketed coils designed to hold strong and firm in the center third of the mattress (which is where most of the body weight is concentrated) to better contour your curves and relieve pressure points.

To provide even more back support, this mattress also features a memory foam lumbar crown and spinal wire for healthy alignment. Comfort and luxury are also key, and you can enjoy the plush 3 inch pillow top for cushioned relief. Plus, you can choose from three comfort levels—Saatva rates the plush soft as a 3 and recommends it for lighter weight people or side sleepers, the luxury firm as a 5 to 7 for all sleepers and the firm option as an 8 and says it’s best suited for stomach or back sleepers.

What’s most beneficial about a split king is the ability to get two twin XL mattresses in different firmness levels to ensure each partner has exactly what they need to snooze through the night. What our editors say: Forbes Vetted mattress and sleep editor McKenzie Dillon says the Saatva Classic reminds her of mattresses you sleep on in upscale hotels and says it’s one of the nicest beds available for the price.

She adds, “Its dual coil design sets it apart from a majority of online beds that only have one innerspring layer. Combine this with its multiple lumbar support layers and plush pillow top, and you’ve got a great mattress for people with back pain.” However, she finds each model to be firmer than advertised.

Best Split King Mattress For Side Sleepers Helix Type : Hybrid | Firmness : Medium | Delivery : Bed in a box | Trial : 100 nights | Warranty : 15 years The medium feel of the Helix Midnight Luxe makes it an excellent option for side and back sleepers or those who frequently toss and turn at night. The comfort level is rated a 5 to 6, making it soft enough to cushion the hips and shoulders yet firm enough to provide support.

As a hybrid mattress, it contains both coils and foam. The individually wrapped coils are designed to cradle your body and reinforce support under the hips for lumbar support, while the memory foam reacts to your body weight to contour where it’s needed. Another reason this mattress is ideal for side sleepers is its 14 inch depth, giving your body more than a foot of support and cushion.

However, the medium firm feel and slight bounce also makes this model great for other sleeping positions or those who toss and turn. Instead of a specific split king size, you need to purchase two twin XL mattresses. What our editors say: Forbes Vetted executive strategy editor Lindsay Boyers recommends the Helix Midnight Luxe for side sleepers and mentions that both she and her fiancé felt comfortable and supported throughout the night.

Boyers also appreciates the foam as it dampened motion transfer, so you won’t get jostled awake when your partner or furry friend moves around. Chapman adds, “I think the Midnight Luxe is a great option for back and side sleepers who want just the right amount of cushioning and support. Overall, it’s a great value in my book.” Best Cooling Split Mattress Brooklyn Bedding Type: Hybrid | Firmness: Soft, medium and firm | Delivery: Bed in a box | Trial: 120 nights | Warranty: 10 years The Brooklyn Bedding Aurora Luxe Mattress is available in three firmness levels, with the option of adding a cloud pillow top for additional comfort.

The soft model (rated a 3 by Brooklyn Bedding) is recommended for side sleepers or those who enjoy the feeling of being hugged, medium (rated a 5) is best suited for combination back, stomach and side sleepers and the brand says those who snooze primarily on their stomach or back should choose the firm model, which is rated a 7.

The multiple comfort levels allow couples to choose their preferred firmness level in a twin XL and combine them to create a split king bed. Cooling is one of the primary benefits of this mattress, with a ton of features to ensure hot sleepers can find comfort. To start, it features a cover with cool tech fibers that actively work to remove excess heat from the sleep surface.

The hybrid design boasts open cell technology for optimal airflow that prevents heat retention and cooling infused foam that absorbs excess body heat. What our editors say: Chapman has slept on the medium Aurora Luxe model with a pillow top and says she finds it comfortable for both back and side sleeping.

“It has a nice level of cushioning and lift—you don’t get deep sinkage or feel stuck in the bed,” she says. “I also have found it to have strong motion isolation and edge support.” However, she also loves an extra soft mattress and says she could see herself swapping it out for the soft model.

Best Firm Split King Mattress WinkBeds Type: Hybrid | Firmness: Softer, luxury firm, firm or plus | Delivery: Bed in a box | Trial: 120 nights | Warranty: Lifetime If one partner requires an ultra firm mattress, the split king Winkbed (which is made up of two twin XL mattresses) is a top choice. You can choose from four comfort levels.

The firm is rated 7.5 out of 10 by Winkbeds and is designed for stomach sleepers, while the Plus is rated an 8 and is suggested for heavier individuals or those who need more back support. On the plush side is the soft model, which is rated 4.5 out of 10 and is recommended for side sleepers, and lastly, the luxury firm is rated 6.5 and suggested for combination sleepers.

As a hybrid model, it contains both foam and innersprings. The individually pocketed coils are designed to provide targeted back support in the areas where you need it most. Sitting atop the coils is gel foam to absorb motion transfer and a foam Euro pillow top to keep your back, hips and shoulders aligned.

What our editors and the reviews say: Chapman says the Winkbed embodies a luxury innerspring feel. “It reminds me of a mattress you’d find in a nice hotel and is extremely supportive. I also really appreciate how breathable its materials are.” One five star reviewer adds, “ I’ve had the [Winkbed Plus] mattress for two and a half months now.

I weigh 350 pounds and this is the first mattress I’ve owned that has enough support in the middle. I don’t have back pain anymore.” Best Organic Split King Mattress Avocado Type: Hybrid | Firmness: Plush, medium or firm | Delivery: Bed in a box with optional white glove delivery | Trial: 365 nights | Warranty : 25 years Avocado Green is known for using quality products with certified organic materials, so you can feel good about what you’re sleeping on while you have a restful night.

The brand doesn’t use polyurethane foam, chemical adhesives or flame retardants and also ensures every mattress is Greenguard Gold Certified for low emissions. Plus, each mattress is needle tufted by hand and assembled in the United States. It’s available in a plush, medium or firm feel, making it a good fit for most sleepers.

The plush sits about 15.5 inches high, while the firm features less latex and is 11 inches tall. In addition to GOLS certified organic Dunlop latex, this hybrid mattress also features individually encased steel coils arranged in seven distinct zones to keep your back aligned and distribute weight more evenly.

The coils also float independently to contour your body’s natural curves. What our editors say: Boyers tested the medium firmness with the pillow top and highly recommends it for a plush feel with ample support. She thinks the pillow top was great at isolating motion, and she could barely feel her partner moving around in bed.

“The biggest draw of the Avocado Green Mattress is its natural and organic construction, but it’s also super comfortable.” Chapman agrees the pillow top Avocado Green model has a soft, plush feel. “It’s definitely a soft, bouncy and supportive bed,” she says. Why Trust Forbes Vetted The Forbes Vetted team spends countless days and nights researching, testing and thinking about sleep.

And just like you, we yearn for a restful night of sleep and actively search for the best products to make that happen. From the editors to the writers, we’ve produced hundreds of guides on mattresses and sleep in which we interview medical experts, rely on firsthand experience and consult top mattress brands.

We continually monitor discounts and product information to make sure this guide is always up to date. How We Chose The Best Split King Mattresses To ensure we offer the best products, we consulted Dr. Nathan Holley, D.C ., a chiropractor with a dozen years of clinical practice. When asked for his advice to those seeking a split king mattress, he said, “I always recommend mattresses with a trial of at least a month or more to see if their back responds well.

Adjustable mattresses are also a huge plus if you want to go that route, as they can be customized to the patient.” Because of this, each mattress on our list has a trial period of no less than 120 days and a warranty of 10 years minimum. We also included an adjustable mattress and models that are compatible with split king adjustable bed frames.

Of course, each model is available in a split king or a twin XL (which means you have to buy two). We wanted to make sure all sleeping types could find a suitable mattress, which is why we included air bed, memory foam and hybrid options, as well as comfort levels ranging from soft to ultra firm. What’s more, most of the mattresses on this list have been personally tested by our Forbes Vetted editors, including senior sleep editor Bridget Chapman and sleep editor McKenzie Dillon ..
