The best split king mattress for an adjustable bed is a pair of compatible Twin XL mattresses, especially if each sleeper wants independent head and foot positions. If you need a complete setup, Marsail, ESHINE, EGOHOME, Celestial Sleep, and Vipbear offer base-and-mattress bundles; if you already own a base, focus on mattress fit and flexibility.

A split king is typically made from two Twin XL mattresses placed side by side. The split lets each sleeper move their side without lifting or bending one shared king mattress.

Which split king mattresses work best with adjustable beds?

The best fit depends on whether you need a full bundle or replacement mattresses for a base you already own. These picks include complete split king sets, plus two king-size replacement mattresses that suit a different kind of setup.

We compared the stated mattress sizes, materials, adjustment features, and bundle contents against the needs of a split king bed. Our score weighs specs, features and buyer feedback against what you're shopping for.

ESHINE suits shoppers who want a hybrid bundle

1

ESHINE Split King Adjustable Bed Frame: Best for a feature-rich hybrid bundle

9.7/10Our score

• 14 in hybrid mattress
• 55° head and 42° foot tilt
• Zero Gravity and Anti-Snore presets
• Massage modes

This split king set pairs a 14 in hybrid mattress with a base offering independent head and foot adjustment, massage modes, and remote presets.

See it on Amazon

Pros

• Base and mattress come together
• Hybrid mattress has gel-infused foam
• Includes massage and Zero Gravity features

Cons

• Ships in 4 boxes that may arrive separately
• Assembly is required

The ESHINE set combines a split king adjustable base with a 14 in hybrid mattress. Its base raises the head up to 55° and feet up to 42°, and the remote includes Zero Gravity, Anti-Snore, and three memory presets.

The mattress pairs pocket springs with CertiPUR-US certified gel-infused foam. ESHINE also describes massage modes, USB ports, and under-bed lighting, which may suit shoppers who want more than basic head and foot adjustment.

The frame has a steel-reinforced base and mattress retention bars. It ships in four boxes, which may arrive separately, and assembly is required.

Choose this set if you'd like the base and hybrid mattress together, with remote presets and massage. If you already have a base, look for replacement Twin XL mattresses that match its size and flexibility requirements.

MLILY EGOHOME is a one-piece king replacement

2

MLILY EGOHOME King 14 inch Memory Foam: Best for a king-size foam replacement

9.7/10Our score

• 14 in memory foam
• Medium-firm feel
• Graphene cooling cover
• CertiPUR-US certified foam

This king mattress is a replacement option for a one-piece king setup, not a pair of Twin XL mattresses for split king movement.

See it on Amazon

Pros

• Medium-firm memory foam
• Graphene cooling cover
• CertiPUR-US certified foam

Cons

• King size does not allow independent split king positions
• No trial period; opened mattresses cannot be returned

This MLILY EGOHOME mattress is a 14 in medium-firm memory foam king with a graphene cooling cover. Its foam includes copper gel aerofuion memory foam, Adaptifoam, and a high-density foam base.

The king size is useful for a conventional king setup, but it is not a pair of Twin XL mattresses. On a split king base, one continuous mattress won't let each side move independently.

MLILY says its foam is CertiPUR-US certified and includes a 10-year limited warranty. There is no trial period, and opened mattresses cannot be returned.

Choose it for a king bed that moves as one surface. If you want independent motion, compare separate Twin XL models in our guide to the best mattress for an adjustable bed.

Marsail provides a complete adjustable split king set

3

Marsail Split King Adjustable Bed Frame: Best for independent head and foot control

9.6/10Our score

• Split king base and mattress bundle
• Head and foot angles up to 65° and 45°
• Gel memory foam mattress

Marsail combines a split king adjustable base with two Twin XL mattresses, plus separate head and foot controls and massage settings.

See it on Amazon

Pros

• Complete split king bundle
• Independent head and foot adjustment
• Tool-free frame assembly

Cons

• Warranty is 1 year

Marsail combines a split king base with two 14 in Twin XL memory foam mattresses. The base offers head and foot angles up to 65° and 45°, along with Zero Gravity and TV Mode presets.

Its three-layer gel memory foam mattress has a graphene-infused cover and breathable open-cell foam. The maker says the mattress can take up to 72 hours to expand after unboxing.

The remote also controls three-speed vibration massage and saves two positions. Marsail describes tool-free assembly in three steps, and includes a one-year warranty.

This set fits shoppers who want separate movement and a foam mattress in one order. For a mattress-only comparison, see our best king mattress for adjustable base guide, which covers one-piece king setups.

EGOHOME combines a split base with medium-firm foam

4

EGOHOME Split King Adjustable Bed Frame: Best for a medium-firm foam bundle

9.4/10Our score

• Split king base and mattress bundle
• Medium-firm gel-infused foam
• 58° head and 37° leg lift
• Mattress fits 8–14 in thickness range

The EGOHOME set includes two adjustable bases and two mattresses, with a medium-firm gel-infused foam mattress and wireless remote.

See it on Amazon

Pros

• Complete split king bundle
• Retainer bar helps hold each mattress
• 750 lb maximum weight recommendation

Cons

• No trial period; opened mattresses cannot be returned
• Frame and mattress warranty terms need confirmation

The EGOHOME split king set includes two adjustable bases and two mattresses. Its medium-firm gel-infused memory foam mattress has a graphene-infused cover, and the base raises the head up to 58° and legs up to 37°.

A wireless remote includes Zero Gravity and Flat presets, while a retainer bar helps keep each mattress in place during adjustment. The frame is described as fitting mattresses from 8 to 14 in thick, which gives you a useful range to check against your mattress choice.

There is no trial period, and opened mattresses cannot be returned. The provided warranty details don't state a term, so confirm coverage before buying.

Choose this if you want two foam mattresses and bases in one bundle. If you own a base already, compare the frame's thickness range and your base's requirements before using replacement mattresses.

KUTUU protects the two mattress surfaces

5

KUTUU Waterproof Split King Mattress Protector: Best for protecting two Twin XL mattresses

9.3/10Our score

• Two protectors sized 39 x 80 in
• Waterproof TPU backing
• 6–18 in deep pockets
• Machine washable

The two-piece protector set is sized for split king mattresses and has a deep pocket design with a 360° elastic skirt.

See it on Amazon

Pros

• Two protectors for split king sides
• Waterproof backing
• Machine washable

Cons

• Check mattress dimensions and depth before buying
• Protector does not replace a mattress

KUTUU sells two waterproof protectors sized 39 x 80 in, a common Twin XL size for split king setups. The 360° elastic skirt is designed for mattresses 6–18 in deep.

The quilted polyester surface has a TPU backing, and KUTUU describes it as breathable and quiet. Each protector is machine washable, with tumble drying on low heat recommended.

This is an accessory, not a mattress replacement, but it helps keep both sides covered without joining them into one surface. Measure mattress depth and check that the protector won't interfere with the bed's movement.

Choose this pair if spill protection matters and the dimensions match your mattresses. For a one-piece king bed instead, our best split king adjustable beds with mattresses guide can help you compare complete bundle options.

Grbsy offers a taller hybrid king mattress

6

Grbsy 16 Inch King Size Mattress: Best for a taller one-piece king mattress

9.2/10Our score

• 16 in hybrid construction
• Medium-firm feel
• Pocketed springs and memory foam
• 7-zone support

This 16 in king hybrid has memory foam and pocket springs, but its one-piece king size does not provide two independent Twin XL sides.

See it on Amazon

Pros

• Hybrid foam and pocket spring construction
• Medium-firm feel
• 365-night trial stated by Grbsy

Cons

• One-piece king cannot flex independently on split bases
• Confirm base compatibility and clearance before buying

Grbsy's 16 in hybrid is a medium-firm king mattress built with memory foam and pocketed springs. The mattress uses a Euro-top and describes 7-zone support, plus a breathable cover and cooling gel memory foam.

This is a one-piece king mattress, not a pair of Twin XL mattresses. It may suit a standard king base that adjusts as one surface, but it cannot provide separate movement on a split king base.

Grbsy states that the mattress has a 365-night trial and a 10-year warranty. Its 16 in thickness also makes it important to check a base's mattress limits and your room's clearance before buying.

Choose it if you want a taller hybrid king and your base supports that mattress size. For independent split king positioning, choose two compatible Twin XL mattresses instead.

Celestial Sleep is a softer foam bundle

7

Celestial Aurora Adjustable Bed Base: Best for a softer foam bundle

9.0/10Our score

• Split king base and two mattresses
• 12 in gel memory foam
• 60° back and 45° leg lift
• Zero Gravity and Anti-Snore buttons

Celestial Sleep pairs a split king base with two 12 in gel memory foam mattresses and a remote with memory positions.

See it on Amazon

Pros

• Complete split king bundle
• Head and foot lift
• 10-year base warranty stated by Celestial Sleep

Cons

• Medium-soft feel may not suit shoppers seeking firmer foam
• Ships in separate boxes

Celestial Sleep pairs a split king base with two 12 in gel memory foam mattresses. The mattresses are described as medium soft, while the base lifts the head to 60° and legs to 45°.

The wireless remote has Zero Gravity and Anti-Snore buttons, memory positions, and a flashlight. Celestial Sleep describes a 10-year warranty for the base, and says the bundle ships in four separate boxes.

This set may suit sleepers who prefer a softer feel and want the base included. If you need a firmer surface, compare mattress feel carefully because firmness labels are subjective.

ESHINE's 12 in hybrid has pocket springs

8

ESHINE Split King Adjustable Bed Frame: Best for a pocket-spring hybrid

8.6/10Our score

• 12 in hybrid mattress
• 319 individually wrapped pocket springs
• 55° head and 42° foot adjustment
• App and wireless remote

ESHINE pairs its E2000 base with a 12 in hybrid mattress built with individually wrapped pocket springs and gel-infused memory foam.

See it on Amazon

Pros

• Complete split king set
• App and remote controls
• Tool-free setup is described as taking 5 minutes

Cons

• Ships in 4 boxes
• Confirm mattress fit and clearance with your base

This ESHINE set pairs an adjustable base with a 12 in hybrid mattress made with 319 individually wrapped pocket springs. The comfort layers include gel-infused memory foam and high-density foam.

The base adjusts the head up to 55° and feet up to 42°. You can use the app or wireless remote for Zero Gravity, Anti-Snore, Flat, and saved positions.

ESHINE describes the setup as tool-free and says the bundle ships in four boxes. The stated weight capacity is 750 lb, and the base has a 10-year limited warranty.

Choose this set if you want a hybrid bundle with pocket springs and app control. Check the mattress dimensions against your base before ordering a replacement or adding accessories.

Vipbear pairs a grey foam mattress with its base

9

Vipbear Adjustable Bed Frame Split King: Best for a grey foam set

8.3/10Our score

• Split king base and Twin XL mattress
• 12 in gel memory foam
• Medium-firm feel
• Separate head and foot lift

Vipbear offers a split king adjustable frame with a 12 in medium-firm gel memory foam mattress and wireless remote.

See it on Amazon

Pros

• Base and mattress are sold together
• Separate head and foot lift
• 750 lb maximum weight recommendation

Cons

• Assembly is required
• Warranty information differs between the description and specifications

Vipbear's split king bundle includes an adjustable base and a 12 in grey gel memory foam mattress with a medium-firm feel. Its remote controls separate head and foot lift, with head adjustment up to 65° and foot lift up to 45°.

The base has adjustable legs and a metal support frame. Vipbear says assembly is required, and its description gives a 750 lb maximum weight recommendation.

The warranty information is inconsistent: the description says lifetime coverage, while the specifications state three years. Confirm the terms with Vipbear before relying on either duration.

Choose it if the included mattress feel and base controls match your needs. If you plan to use another mattress, confirm the base's fit and thickness limits first.

How do you choose a replacement split king mattress?

Choose two Twin XL mattresses that fit your base and can flex with its movement. Check the base manual for mattress type, thickness, retention bars, and any clearance limits.

A one-piece king mattress won't bend independently with split king sections. If both sides of your base move together, a king mattress may work, but confirm the base supports that size.

Think about mattress material as well. Memory foam often bends readily, while hybrid designs vary by their foam layers and coil construction, so check the manufacturer's compatibility guidance before buying.

For another size comparison, our guide to the best Twin XL mattress for adjustable bed covers individual mattresses for a single adjustable side.

What should you check before ordering a split king set?

Check that the set includes two mattresses and two base sections if you need a complete split king. Bundle names can be similar, so verify the included pieces, mattress dimensions, and any separate shipping details.

Measure the bed area and nearby furniture with the base fully raised. Confirm that cables, nightstands, and bedroom walls won't block the range of motion.

Also check how the remote controls the sides. Some systems let each sleeper move independently, while bundle features and control details can differ.

A protector should fit each mattress without pulling when the bed flexes. KUTUU's two-piece set has 6–18 in deep pockets, so measure each mattress before choosing it.

Is a split king right for your bedroom?

A split king is a practical choice when two sleepers want different positions or mattress feels. Each side can move independently, but the center seam and two separate surfaces may feel different from one continuous king mattress.

Choose it if independent adjustment matters more than having a single uninterrupted sleep surface. If you want a standard king mattress and base that adjust together, compare the mattress size and base design before switching to a split setup.

Which split king mattress should you choose for an adjustable bed?

Pick Marsail if you want a complete split king bundle with two Twin XL foam mattresses and independent controls. Choose ESHINE for a 14 in hybrid set with massage, or Celestial Sleep for a softer 12 in foam bundle.

If you already own a base, buy two compatible Twin XL mattresses and confirm the base's size and thickness limits. For a king surface that moves together, choose a one-piece king mattress only when the base supports it.

Frequently asked questions

What mattress size makes a split king?

A split king usually uses two Twin XL mattresses side by side. Each mattress needs to fit one side of the base, so check the dimensions and confirm the exact mattress configuration before ordering.

A one-piece king mattress cannot move independently on the two sides.

Can any mattress go on a split king adjustable bed?

No. Each side needs a mattress that can flex with the base, and the mattress must match the base's size and thickness limits.

Check the base instructions for compatible mattress types, retention features, and clearance before buying.

A one-piece king mattress won't allow independent movement.

Is a split king mattress the same as two Twin XL mattresses?

A split king setup commonly combines two Twin XL mattresses, one for each side. The pair gives each sleeper a separate surface that can move independently when used with a split king adjustable base.

Check whether a bundle includes both mattresses and both base sections.

Can I use a king mattress on a split king adjustable base?

A one-piece king mattress spans both sides, so it won't bend with independent movement on a split king base. Choose two compatible Twin XL mattresses if you want each side to adjust separately.

A one-piece king may suit a standard king base that moves both sides together.

Do split king mattresses need separate protectors?

Separate protectors let each Twin XL mattress move with its own adjustable section. KUTUU's set includes two protectors sized 39 x 80 in, with pockets for mattresses 6–18 in deep.

Measure both mattresses, including their depth, before choosing a protector.
