Best Adjustable Beds for Zero Gravity Sleep 2026: Top Bases, Presets & Exact Angles
Zero Gravity has gone from being a premium adjustable-bed feature to one of the main reasons people buy an adjustable base in the first place.
Instead of sleeping completely flat, a Zero Gravity position raises both the upper body and legs. The goal is to reduce the amount of pressure concentrated on your lower back and create a more supported, almost weightless-feeling position.
But not every adjustable bed handles Zero Gravity equally well.
Some bases give you a simple one-touch preset. Others let you fine-tune the head and foot angles, save custom positions, add lumbar support, use massage, or independently adjust each side of a Split King.
So which adjustable beds are best if Zero Gravity is one of your priorities?
In this 2026 guide, we'll explain how Zero Gravity works, the approximate angles you should start with, which adjustable-base features actually matter, and some of the best Zero Gravity adjustable beds to consider.
Quick Picks: Best Adjustable Beds for Zero Gravity in 2026
If you want the short version, these are the types of bases we'd look at first:
Best Overall Zero Gravity Adjustable Base: TEMPUR-Ergo® Smart Base
Best Premium Zero Gravity Base: TEMPUR-Ergo® ProSmart® Base
Best Value: Ergomotion RIO Series
Best Simple Zero Gravity Base: Ergomotion ErgoAdapt
Best for Maximum Position Customization: Premium Ergomotion and Reverie bases
Best for Couples: Split King adjustable-base configuration
Best for Shoppers Who Want Extra Lower-Back Support: Adjustable base with independent lumbar support
The right model ultimately depends on how much customization you want, whether you're buying a new mattress at the same time, and whether features such as massage, lumbar adjustment, sleep tracking or independent sides matter to you.
What Is the Zero Gravity Sleep Position?
The Zero Gravity position places your body in a gently elevated posture rather than lying completely flat.
Typically:
- Your head and upper torso are elevated.
- Your knees are bent.
- Your lower legs are raised.
- Your hips remain lower than your knees.
- Your weight is distributed across a larger portion of the mattress.
The concept is inspired by the neutral-body posture associated with reduced loading on the body.
In practical bedroom terms, it simply means finding a position where your upper and lower body are both elevated enough that your back, hips and legs feel supported instead of stretched flat across the mattress.
Today's better adjustable bases make this extremely easy by including a Zero Gravity or Zero-G button on the remote.
Press it once and the base moves automatically into its preset position.
What Are the Best Zero Gravity Angles?
There is no single angle that is perfect for every person.
Your height, weight, mattress firmness, sleeping position and personal comfort all affect the position that feels best.
However, a very good starting point is:
| Adjustment | Starting Range |
|---|---|
| Upper body/head elevation | 25–35° |
| Knee/leg elevation | 25–40° |
| Head tilt, if available | Slight adjustment only |
| Lumbar support | Low to moderate |
Think of these as starting points rather than rigid rules.
A person who is 6'4" may need a slightly different setting than someone who is 5'4". Likewise, a soft memory-foam mattress can change how your body settles into the position compared with a firmer hybrid.
A simple way to dial it in
Start with approximately:
Head: 30°
Legs: 30–35°
Then make small changes.
If you feel too folded at the waist, lower the head slightly.
If your lower back still feels unsupported, raise the knees a little more.
If your knees feel overly bent, lower the foot section.
The best Zero Gravity position should feel relaxed, not forced.
Is a Zero Gravity Preset the Same on Every Adjustable Bed?
No.
This is one of the most important things shoppers overlook.
The words “Zero Gravity preset” don't mean every manufacturer's base moves to exactly the same angles.
Each company programs its own default position.
That's why we strongly prefer bases that offer either:
- Programmable memory positions
- Independent head and foot adjustment
- Adjustable lumbar support
- Multiple presets
- App-based position control
A factory Zero Gravity preset is convenient, but the ability to modify it is much more valuable over the long term.
You might love the factory setting.
Or you might decide that moving your feet two inches higher makes the position dramatically more comfortable.
Best Adjustable Beds for Zero Gravity Sleep in 2026
1. TEMPUR-Ergo® Smart Base
Best Overall
The TEMPUR-Ergo® Smart Base is one of our favorite choices for shoppers who want a premium Zero Gravity experience combined with advanced comfort features.
It includes a dedicated Zero Gravity preset designed to elevate the head and feet into a weightless-feeling position. BedPlanet's current model also includes adjustable lumbar support, allowing the lower-back area to be raised independently by up to six inches. Bedplanet
That matters because Zero Gravity alone isn't necessarily perfect for every back.
Being able to add a little lumbar support can make a noticeable difference for sleepers who want more support beneath their lower spine.
Why we like it
- One-touch Zero Gravity preset
- Independent head and foot adjustment
- Adjustable lumbar support
- Automatic Snore Response™
- Sleeptracker-AI® sleep monitoring
- Multiple relaxation and sleep positions
- Excellent match for TEMPUR-Pedic mattresses
Best for
People buying a premium adjustable base who want a combination of Zero Gravity, lumbar support and smart sleep technology.
2. TEMPUR-Ergo® ProSmart® Base
Best Premium Zero Gravity Base
For shoppers who want to go beyond basic adjustable-bed functionality, the TEMPUR-Ergo® ProSmart® Base sits near the top of the category.
Both TEMPUR's Smart and ProSmart bases offer the core functions you'd expect from a premium base, including head and foot articulation and Zero Gravity positioning. The ProSmart adds more advanced relaxation features, including upgraded massage and integrated sound technology. Bedplanet
If you're mainly interested in raising your head and feet, you probably don't need to spend the extra money.
But if you want your adjustable bed to function almost like a complete relaxation system, that's where the ProSmart starts to make more sense.
Why we like it
- Excellent Zero Gravity functionality
- Premium articulation
- Lumbar support
- Advanced massage features
- Smart sleep technology
- Premium relaxation features
- Excellent pairing with TEMPUR-Pedic mattresses
Best for
Luxury buyers who expect to use their adjustable bed for sleep, relaxation, reading and massage, not simply head elevation.
3. Ergomotion RIO Series
Best Value for Zero Gravity
Ergomotion is one of the strongest names in adjustable-bed manufacturing, and the RIO lineup gives shoppers several levels of features and pricing.
That's useful because you don't necessarily need every premium feature simply to get a great Zero Gravity position.
As you move through the RIO lineup, features can include:
- Head and foot articulation
- Zero Gravity and other presets
- Programmable memory positions
- Massage
- Under-bed lighting
- USB charging
- Lumbar support on select models
- Zero-clearance compatibility
BedPlanet currently carries multiple RIO models, including the RIO 4.0, RIO 5.0 and RIO 6.0. Bedplanet
Why we like it
The RIO lineup allows you to buy the amount of adjustable bed you actually need.
If Zero Gravity is your primary concern, you can choose a simpler configuration.
If you also want massage, lumbar adjustment or additional memory positions, you can step into a higher model.
Best for
Shoppers looking for a strong balance between price, reliability and adjustable-bed features.
4. Ergomotion ErgoAdapt Adjustable Base
Best Simple Zero Gravity Base
Some people don't need sleep tracking, massage programs and a remote with enough buttons to launch a small aircraft.
They just want:
Head up. Feet up. Zero Gravity. Flat. Done.
That's where the Ergomotion ErgoAdapt becomes interesting.
The ErgoAdapt includes:
- Head articulation
- Foot articulation
- One-touch Zero Gravity
- Flat preset
- Lightweight construction
- Ready-to-assemble design
BedPlanet currently lists the ErgoAdapt at under 100 pounds, making it considerably easier to handle than many traditional adjustable bases. Bedplanet
Why we like it
You're paying for the features people actually use most often instead of loading the base with technology you may never touch.
Best for
Value-focused shoppers who primarily want Zero Gravity and basic independent positioning.
5. Ergomotion Ascend High-Low Adjustable Bed
Best for Additional Positioning Flexibility
The Ergomotion Ascend takes adjustable positioning a step further.
In addition to standard head and foot articulation and a Zero Gravity position, the entire platform can raise or lower. It can also tilt the entire mattress surface up to seven degrees while keeping the sleeping surface relatively flat. Bedplanet
It includes three programmable presets and a wireless remote.
That makes it especially interesting for someone who wants more than the typical head-and-foot adjustable bed.
Why we like it
- Zero Gravity position
- Head and foot articulation
- High-low height adjustment
- Up to 7° full-bed tilt
- Three programmable presets
- Under-bed lighting
- Zero-clearance design
Best for
People who want greater control over overall bed positioning, including sleepers who may have difficulty getting into or out of bed.
6. Reverie Adjustable Bases
Best for Fine-Tuning Your Position
Reverie has long focused on customizable adjustable-bed positioning.
For Zero Gravity shoppers, that's particularly useful because the ideal setting isn't necessarily the manufacturer's factory preset.
Depending on the model, Reverie bases may combine:
- Zero Gravity presets
- Independent head and foot movement
- Programmable positions
- Massage
- App controls
- Advanced position customization
In BedPlanet's 2026 comparison of Reverie, Ergomotion and Rize, all three perform well in Zero Gravity, with Reverie standing out particularly for customization and smooth articulation. Bedplanet
Best for
Sleepers who enjoy experimenting with their position and want to fine-tune Zero Gravity rather than simply pressing one preset button.
Which Features Matter Most for Zero Gravity?
If Zero Gravity is the main reason you're buying an adjustable bed, we would prioritize these features in roughly this order.
1. Independent Head and Foot Adjustment
This is essential.
You want to be able to adjust the upper and lower halves of the bed separately.
That allows you to modify the manufacturer's Zero Gravity position rather than being stuck with it.
2. One-Touch Zero Gravity Preset
Technically, you could manually recreate Zero Gravity every night.
You probably won't.
A dedicated button makes the feature dramatically more useful.
Press ZERO G and the base moves there automatically.
3. Programmable Memory Positions
This may actually be more valuable than having several factory presets.
Once you find your perfect position, save it.
For example:
Memory 1: Your Zero Gravity sleep position
Memory 2: TV/reading position
Memory 3: Slight nighttime head elevation
Now you aren't hunting for the perfect angles every night.
4. Lumbar Support
Lumbar support is becoming one of our favorite premium adjustable-base features.
A normal adjustable base raises your entire upper body.
A base with adjustable lumbar support can separately lift the area beneath your lower back.
For someone using Zero Gravity specifically because of lower-back comfort, that extra adjustment can be extremely useful.
The TEMPUR-Ergo Smart Base, for example, currently includes adjustable lumbar support capable of lifting that area independently. Bedplanet
5. Massage
Massage isn't required for Zero Gravity.
But the two features work extremely well together.
Elevating your legs and upper body into Zero Gravity while using a low-intensity massage setting can create a very relaxing position before sleep.
For many owners, this ends up becoming their evening TV or wind-down position.
6. Split King Independent Adjustment
For couples, this can be huge.
A Split King setup generally uses:
Two Twin XL mattresses + two independently controlled adjustable bases.
That means one person can sleep in Zero Gravity while the other remains nearly flat.
One partner might prefer:
Head 30° / Feet 35°
while the other uses:
Head 10° / Feet 5°
Neither person has to compromise.
Zero Gravity vs. Sleeping Flat
Neither position is universally better.
Sleeping flat remains perfectly comfortable for many people.
The advantage of an adjustable base is simply that you aren't limited to flat anymore.
Zero Gravity may feel better when:
- Your lower back feels uncomfortable while lying flat
- You like sleeping with your knees elevated
- Your legs feel tired after standing all day
- You want to relax before bed
- You prefer some upper-body elevation
- You read or watch television in bed
And if Zero Gravity doesn't feel right?
Press Flat and go back.
That's one of the great things about an adjustable bed.
Zero Gravity vs. Anti-Snore Position
These two presets are not the same.
Zero Gravity
Raises both the upper body and legs.
Anti-Snore
Typically raises only the head or upper torso slightly.
A mild head elevation may be enough for some people, while the full Zero Gravity posture may feel more comfortable for others.
Some premium smart bases can even react when snoring is detected.
For example, TEMPUR's current Smart Base includes Snore Response™, which can automatically raise the head approximately 12 degrees after detecting snoring. Bedplanet
Zero Gravity vs. Full-Bed Incline
These are also different.
With traditional Zero Gravity, the adjustable base bends at multiple points:
Head rises + knees bend + legs rise.
With full-bed incline or tilt, the mattress surface remains relatively straight while the entire bed is angled.
The Ergomotion Ascend, for example, can tilt the complete sleeping platform up to approximately 7°. Bedplanet
Some sleepers may prefer one style over the other.
What Mattress Works Best With Zero Gravity?
Your mattress needs to flex properly as the base moves.
Generally, the best options are:
Memory Foam
Usually excellent for adjustable bases because the mattress conforms easily as the base changes position.
Hybrid
Many modern hybrids are specifically engineered for adjustable bases and provide an excellent combination of support and flexibility.
Latex
Can work very well depending on construction and thickness.
Traditional Innerspring
This is where you need to be more careful.
Older or extremely rigid innerspring mattresses may not flex properly on an adjustable base.
BedPlanet generally recommends memory foam, compatible hybrid and appropriate latex mattresses for adjustable-bed use. Bedplanet
Always verify that the mattress manufacturer approves the mattress for use with an adjustable base.
What Firmness Is Best for Zero Gravity?
There's no universal answer.
However, an extremely firm, rigid mattress may reduce some of the conforming sensation that makes Zero Gravity comfortable.
For many shoppers, medium through medium-firm provides a good balance of:
- Flexibility
- Pressure relief
- Support
- Conforming comfort
But body weight and personal preference matter much more than a number on a firmness scale.
Best Zero Gravity Setup for Couples
For couples with different sleep preferences, we generally recommend looking at a Split King.
This gives each person independent control.
Example
Sleeper A
Zero Gravity
Head: 30°
Legs: 35°
Sleeper B
Mostly flat
Head: 8°
Legs: 5°
You can still have the overall footprint of a King mattress while gaining two independently adjustable sides.
This is particularly valuable if:
- One person likes Zero Gravity and the other doesn't
- One person snores
- One partner reads in bed
- You have different height or comfort needs
- One sleeper prefers more leg elevation
How Much Should You Spend on a Zero Gravity Adjustable Bed?
You don't need the most expensive base simply to get Zero Gravity.
A rough way to think about the market is:
Entry Level
Usually focused on:
- Head adjustment
- Foot adjustment
- Zero Gravity
- Flat preset
This is often enough for someone primarily interested in sleep positioning.
Midrange
Usually adds:
- Massage
- Memory positions
- USB charging
- Under-bed lighting
- Better remotes
- Zero-clearance compatibility
This is probably the sweet spot for most buyers.
Premium
Typically adds features like:
- Lumbar adjustment
- Advanced massage
- Smart sleep tracking
- Snore detection
- App integration
- Sound systems
- More sophisticated articulation
Whether those features are worth paying for depends on how often you'll use them.
Is Zero Gravity Worth Paying Extra For?
In our opinion, yes — but you often don't have to pay much extra anymore.
Zero Gravity has become common enough that many reasonably priced adjustable bases now include it.
We would generally choose a base with Zero Gravity over an otherwise similar model without it.
The feature is useful even if you don't ultimately sleep in that position all night.
A lot of owners use Zero Gravity for:
- Watching television
- Reading
- Relaxing
- Taking pressure off their lower back after work
- Napping
- Massage sessions
So even occasional use can justify having it available.
Do You Have to Sleep in Zero Gravity All Night?
Absolutely not.
Some people love it for the entire night.
Others use it for 20–30 minutes while relaxing and then flatten the bed before falling asleep.
And some people find a customized position halfway between Zero Gravity and flat works best.
That's why adjustable beds are useful.
There isn't one correct position.
Can Side Sleepers Use Zero Gravity?
Yes, although side sleepers usually require less dramatic elevation than back sleepers.
Too much bend at the waist or knees can feel awkward when lying on your side.
Side sleepers may prefer:
- Slight upper-body elevation
- Mild knee elevation
- A supportive mattress
- A softer shoulder comfort zone
Experiment with lower angles rather than automatically using the manufacturer's full Zero Gravity preset.
Can Stomach Sleepers Use Zero Gravity?
Usually with more caution.
Strong head-and-leg elevation can place a stomach sleeper in an uncomfortable curved position.
Stomach sleepers often prefer:
- Very mild head elevation
- Minimal knee elevation
- Or a full-bed tilt system rather than aggressive articulation
A base like the Ergomotion Ascend is interesting here because it can tilt the entire sleeping surface rather than requiring the mattress to bend dramatically. Bedplanet
How to Find Your Perfect Zero Gravity Position
Try this simple process.
Step 1: Start Flat
Lie in your normal sleeping position.
Step 2: Raise Your Knees
Raise the foot section until your knees are comfortably bent.
Step 3: Raise Your Upper Body
Gradually raise the head section to approximately 25–30 degrees.
Step 4: Fine-Tune the Legs
Increase or decrease leg elevation until your lower back feels supported.
Step 5: Adjust Lumbar Support
If your base includes it, add only enough lumbar elevation to fill the natural gap beneath your lower back.
Step 6: Save It
Once you've found the perfect setting, assign it to a programmable memory button.
Now you've created your Zero Gravity position instead of relying on someone else's factory preset.
Frequently Asked Questions
What angle is a Zero Gravity bed?
There isn't one universal Zero Gravity angle. A useful starting range is approximately 25–35° of upper-body elevation and 25–40° of leg elevation, followed by small adjustments based on comfort.
Should your feet be above your heart in Zero Gravity?
The legs are typically elevated substantially in a Zero Gravity position, although the exact relationship between the feet and heart will vary based on the adjustable base, mattress and user's body proportions.
Comfort should be the primary guide.
Can you sleep in Zero Gravity every night?
Many adjustable-bed owners do.
Others use Zero Gravity primarily for relaxation before returning to a flatter position.
Choose whichever position allows you to sleep comfortably.
Does every adjustable bed have Zero Gravity?
No.
Many modern bases include it, but some entry-level adjustable bases only provide manual head and foot adjustment.
Check the product's remote and feature list for a dedicated Zero Gravity or Zero-G preset.
Is Zero Gravity better than raising only your head?
They're designed for different purposes.
Head elevation changes primarily the upper body.
Zero Gravity elevates both your upper and lower body.
Some people strongly prefer one over the other.
Do I need massage for Zero Gravity?
No.
Massage is entirely optional.
However, combining Zero Gravity with a low massage setting can create an extremely comfortable relaxation position.
Is Split King worth it for Zero Gravity?
For couples with different sleep preferences, absolutely.
A Split King allows each person to independently control head and leg elevation rather than forcing both partners into the same position.
Final Verdict: Which Zero Gravity Adjustable Bed Should You Buy?
You don't need to buy the most expensive adjustable base available to enjoy Zero Gravity.
What matters most is finding a base that gives you:
- Independent head and foot articulation
- A one-touch Zero Gravity preset
- Enough customization to fine-tune the position
- A mattress that flexes properly with the base
For a straightforward Zero Gravity experience, a simpler Ergomotion base may be all you need.
For additional customization and premium features, the Ergomotion RIO family and Reverie bases give you substantially more control.
And if you're building a premium sleep system and want features such as lumbar support, sleep monitoring and automatic snore response, the TEMPUR-Ergo Smart and ProSmart bases are among the strongest options BedPlanet currently offers. Bedplanet
For couples, we'd strongly consider a Split King configuration, particularly when one person loves Zero Gravity and the other prefers a flatter sleeping position.
The key is not finding a magical universal Zero Gravity angle.
It's finding an adjustable base that lets you discover your ideal angle — and then save it.
