On this page (4 sections)
The best split king mattress setup gives each partner a separate Twin XL mattress, often paired with a split adjustable base for independent positions. ESHINE is the top bundle here, while Purple and Celestial Sleep are mattress-only split king options.
A split king can help when one sleeper wants a firmer surface, or when partners prefer different bed positions. The main choice is between a pair of separate mattresses and a single mattress built in split king size.
If you are still comparing construction types, our simple guide to mattress types explains how foam, hybrid and other builds differ.

Which split king mattress is best for different setups?
ESHINE ranks first for its base and hybrid mattress bundle, while Purple and Celestial Sleep are the two mattress-only split king picks in this group. The other options help if you want a gap bridge or prefer one continuous king surface.
ESHINE Split King Adjustable Bed Frame: Best for a complete hybrid bundle
- Split king adjustable base and hybrid mattress
- 55° head tilt and 42° foot elevation
- Remote with 3 memory presets
- Massage modes and dual USB ports
This bundle combines a split king adjustable base with a hybrid mattress. The remote has Zero Gravity, Anti-Snore and 3 memory presets.
Pros
- Base and mattress arrive as one bundle
- Massage modes and under-bed lighting
- 10-year limited warranty for steel base
Cons
- Requires assembly
- Boxes may arrive separately
The ESHINE bundle includes a split king adjustable bed base and a hybrid mattress, which makes it the most complete setup here. The remote includes Zero Gravity, Anti-Snore and 3 memory presets, so each sleeper can adjust position without replacing the base.
The base raises the head up to 55° and the feet up to 42°. It also has massage modes, under-bed lighting and dual USB ports, which may be useful if you read or watch TV in bed.
The included mattress has gel-infused foam and a spring construction. ESHINE says the foam is CertiPUR-US certified and designed to help dissipate heat.
This set suits couples who want the base and mattress together. It requires assembly, and the four boxes may arrive separately.
MLILY EGOHOME King 14 inch Memory Foam: Best for a shared king foam feel
- 14-inch medium-firm memory foam
- Graphene cooling cover
- CertiPUR-US certified foam
- King size
This king memory foam mattress is an option for couples who prefer one shared surface over two separate Twin XL mattresses. Its medium-firm feel is a useful starting point when both sleepers want a similar level of support.
Pros
- Medium-firm feel
- 14-inch profile
- Cooling cover and CertiPUR-US certified foam
Cons
- Not a split king size
- No trial period; opened mattresses cannot be returned
The MLILY EGOHOME is a standard king mattress, not a split king. It fits this guide as a comparison for couples who want a shared foam surface instead of separate movement or separate comfort choices.
The 14-inch mattress has a medium-firm feel, gel memory foam and a high-density foam base. MLILY says the cover combines cooling fabric and graphene technology, and that its foam is CertiPUR-US certified.
This may suit partners who agree on a medium-firm feel and do not need each side to adjust separately. Since it is a king mattress, check whether your base is designed for one king mattress or two Twin XL mattresses.
MLILY states there is no trial period and opened mattresses cannot be returned. Confirm those terms before buying if you need time to decide whether the feel works for both sleepers.
Marsail Split King Adjustable Bed Frame: Best for adjustable positions and massage
- Split king base with mattress
- Head and foot incline up to 65° and 45°
- Zero Gravity and TV modes
- 3-speed vibration massage
Marsail combines a split king adjustable base and 14-inch Twin XL memory foam mattresses. Its two memory presets, massage modes and tool-free assembly suit shoppers who want an adjustable setup with several comfort features.
Pros
- Three massage speeds
- Two memory presets
- CertiPUR-US certified, fiberglass-free foam
Cons
- Mattress expansion can take up to 72 hours
- Warranty is 1 year
Marsail combines a split king adjustable base and two Twin XL memory foam mattresses. The base offers head and foot adjustment, two saved positions, Zero Gravity and TV modes.
Its mattress is 14 inches thick, medium firm, and made with three layers of memory foam. Marsail says the cover uses graphene and the foam has CertiPUR-US certification and is fiberglass-free.
The massage function offers gentle, medium and intense settings. Assembly uses 3 steps without tools, according to Marsail, and the mattress may take up to 72 hours to fully expand after unboxing.
This bundle suits buyers who want massage and independent positioning in one setup. Its warranty is 1 year, so compare that coverage with the other bundled options if long-term protection matters.
Novilla Bliss Mattress King Size: Best for a single foam surface
- 14-inch king memory foam
- Three foam layers
- Medium plush feel
- Motion absorbing construction
Novilla's king mattress offers a single surface with three foam layers and a medium plush feel. It may fit couples who value one continuous sleep area more than separate mattress movement.
Pros
- Single king surface
- CertiPUR-US certified foam
- 100-day trial and 10-year protection
Cons
- Not a split king size
- Medium plush may not suit both sleepers
Novilla's Bliss is a standard king mattress with a medium plush feel. It uses three foam layers, including NanoGel memory foam, and has reinforced edge support.
This can make sense when both partners want one continuous surface and do not need separate firmness choices. Novilla says its foam is CertiPUR-US certified and that the mattress has a 100-day free trial and 10-year protection.
The 14-inch height is worth checking against your fitted sheets and bed height. It is not a split king, so it will not offer independent motion on a split adjustable base.
Choose it if shared comfort matters more than separate adjustment. If you need independent positions, compare it with our guide to the best mattress for an adjustable bed.
EGOHOME Split King Adjustable Bed Frame: Best for a cooling foam bundle
- Split king adjustable base and 14-inch mattress
- 58° head and 37° leg elevation
- Zero Gravity and Flat presets
- 750 lb static load capacity
This split king set pairs an adjustable base with a medium-firm gel memory foam mattress. The wireless remote includes Zero Gravity and Flat presets, and the frame has a mattress retainer bar.
Pros
- Mattress and adjustable base in one set
- Wireless remote with preset positions
- Frame fits several mattress types from 8 to 14 in
Cons
- No trial period; opened mattresses cannot be returned
- Brand is not specified in the product name
EGOHOME's split king set pairs an adjustable base with a 14-inch cooling memory foam mattress. The mattress has a medium-firm feel, and the base offers head and leg elevation with Zero Gravity and Flat presets.
The frame has a 750 lb static load capacity and a retainer bar to help keep the mattress in place during adjustments. EGOHOME says the base fits memory foam, latex and hybrid mattresses between 8 and 14 inches thick.
This bundle suits a couple who want a split setup and a medium-firm foam surface. EGOHOME states there is no trial period and opened mattresses cannot be returned.
Before buying, confirm the exact mattress height and your preferred return terms. For other split base and mattress combinations, read our guide to split king mattresses for adjustable beds.
Vekkia 75” Split King Gap Filler: Best for bridging the center gap
- 75 x 10 in foam bed bridge
- Removable, washable cover
- Includes storage bag
- Works on adjustable beds when mattresses are in similar positions
The foam bridge covers the gap between two mattresses when you want a more continuous center area. On adjustable beds, Vekkia says both sides need to be in the same or a similar position.
Pros
- Removable, washable cover
- Storage bag included
- Designed for gaps from 1.5 to 3 in
Cons
- Can limit independent bed positions
- Adds a layer across the center
The Vekkia bed bridge covers the center gap between two mattresses. Its foam wedge is 75 inches long and 10 inches wide, and the removable cover can be machine washed.
This is an accessory rather than a mattress, but it addresses one of the most common split king concerns: feeling the divide between the two sides. Vekkia says it works with adjustable beds when both mattresses are in the same or a similar position.
That condition matters if you raise one side for reading or TV. The bridge may not stay positioned well when the mattresses move at different angles, so it suits couples who tend to keep both sides level.
Nectar 12” Memory Foam Mattress: Best for a firm king feel
- 12-inch king memory foam
- Firm feel
- Contouring foam and dynamic support foam
- 365-night trial
Nectar is a firm king memory foam option for couples who want one mattress and a firmer feel. Its 12-inch profile is also worth considering when a tall mattress would not suit the bed setup.
Pros
- Firm feel
- King size
- 365-night trial
Cons
- Not a split king size
- A firm feel may not suit both sleepers
Nectar is a standard king mattress with a firm feel, so it is another one-piece comparison rather than a split king option. It uses contouring memory foam and dynamic support foam, with a 12-inch profile.
Nectar describes the feel as firm with some cradling. That may suit a couple who both like a firmer mattress, but it removes the ability to choose separate feels on each side.
The mattress comes compressed in a box, and Nectar says it should be ready in 24 hours. Its stated trial is 365 nights, which gives couples more time to decide whether the shared feel works.
Purple Mattress: Best for responsive pressure relief
- Split king size
- 9.25-inch profile
- 2-inch GelFlex Grid
- Medium-firm feel
The Purple Mattress is available in split king and uses a responsive GelFlex Grid over comfort and support layers. Its medium-firm feel may suit partners who want separate mattress movement with a less conventional surface.
Pros
- Split king size
- Grid designed to adapt as you move
- Air channels in the Grid
Cons
- Distinct surface feel may take getting used to
- No adjustable base is included
Purple is a split king mattress with a 9.25-inch profile and a 2-inch GelFlex Grid. Its medium-firm feel and responsive grid make it different from the foam-only picks.
The grid is designed to flex as you move, while air channels allow airflow through the surface. Purple says the mattress is designed to cradle pressure points and support spinal alignment.
This option suits a couple who wants separate mattresses and is open to a surface that feels different from standard foam. It does not include an adjustable base, so check the base separately if independent positioning is part of your plan.

Celestial Sleep 12 Inch Split King Mattress: Best for a split king foam pair
- 12-inch split king memory foam
- Medium plush feel
- Cooling gel bead memory foam
- CertiPUR-US and OEKO-TEX certified
Celestial Sleep offers a split king mattress with gel bead memory foam and a medium plush feel. It may work for couples who want separate Twin XL mattresses without an adjustable base bundle.
Pros
- Split king size
- CertiPUR-US and OEKO-TEX certified
- Usable on the first day after unboxing
Cons
- May take up to 72 hours to fully expand
- Medium plush may feel too soft for some sleepers
Celestial Sleep is a 12-inch split king memory foam mattress with a medium plush feel. It uses cooling gel bead memory foam, comfort foam and a base foam layer.
The company says its mattresses are made in the USA and use CertiPUR-US and OEKO-TEX certified materials. Celestial Sleep says the mattress is usable on day 1 after unboxing, though full expansion can take up to 72 hours.
Choose this for two separate mattress surfaces without buying a base and mattress bundle. It may be too plush for sleepers who prefer a firmer feel, so compare it with Purple if you want a medium-firm split option.
How do split king mattresses compare with king mattresses?
A split king gives partners separate mattress surfaces, while a standard king uses one shared mattress. The split can suit couples with different comfort preferences or who want independent adjustment.
Most split king setups use two Twin XL mattresses. Together they cover a similar footprint to one king mattress, but the center seam can be noticeable without a bridge or fitted bedding that holds both sides close.
A standard king may feel simpler if both sleepers agree on firmness and do not need independent movement. See our guide to the best king mattress for an adjustable base if you want one mattress on a movable base.
What should you check before buying a split king mattress?
Check the mattress size, base type, height and return terms before ordering. These details determine whether the setup fits your room and lets each side work as intended.
- Confirm the size: A two-piece split king usually uses two Twin XL mattresses. Make sure the base and sheets use the same configuration.
- Choose separate or shared comfort: Two mattresses let each sleeper pick a different feel. One connected split king mattress keeps the center more continuous but does not offer separate firmness.
- Check adjustable compatibility: Confirm the mattress is intended for an adjustable base and that its thickness fits the base's retainer bars and side rails.
- Plan for the center gap: A bed bridge can cover the seam, but it may be less suitable when each side moves to a different angle.
- Read return terms: A mattress that feels right to one sleeper may not suit the other. Check trial and return rules before opening it.
If one sleeper has ongoing pain or sleep problems, talk with a health professional before relying on a mattress change to address it.
Is a split king mattress worth it for couples?
A split king is worth considering when partners need different mattress feels or want separate adjustable positions. The extra flexibility can make the bed more tailored to each person.
Choose ESHINE for a base and hybrid mattress bundle, Marsail for a massage feature set, or Purple if you want a mattress-only split king with a responsive grid. Pick a shared king mattress if both sleepers prefer one continuous surface, and add a bed bridge if the center gap bothers you.
For couples who want different positions, start with the best split king mattress for an adjustable bed. For a single king mattress, compare the best king mattress for an adjustable base.

Frequently asked questions
What is a split king mattress?
A split king usually means two Twin XL mattresses placed side by side on a king-size base. Each sleeper can choose a separate mattress feel, and an adjustable split base can let each side move independently.
A single split king mattress is also available, so check whether a product is one piece or a two-mattress set.
Is a split king the same size as a king?
A standard split king setup uses two Twin XL mattresses, which together cover about the same width and length as a king mattress. Each side can move or feel different when the mattresses are separate.
Check the mattress and base dimensions before buying, since names alone do not confirm a precise fit.
Can you use a gap filler with an adjustable split king?
Yes, but a gap filler works best when both mattresses are in the same or a similar position. A bridge across the center can make the gap less noticeable, though it may interfere with raising one side independently.
Vekkia's 75-inch bridge is designed for this kind of center gap.
Can split king partners choose different mattress feels?
Yes. Two separate Twin XL mattresses let each partner choose a different feel, while keeping the overall bed width close to a king.
This is the main reason couples consider a split setup.
Confirm that each mattress works with the base and bedding you plan to use.
Do split king mattresses work with adjustable beds?
Many split king mattresses are made for adjustable bases, but compatibility depends on the mattress construction and base. Check the mattress maker's guidance for bending and the base's size requirements before ordering.
For a closer look at moving positions, see our best split king mattress for adjustable bed guide.
