After a long day, many people know the feeling: you finally get into bed, but lying completely flat does not always feel as comfortable as you expected. Your back feels tired, your legs feel heavy, and you keep adjusting your pillows trying to find a position that feels just right.
That is where zero gravity sleeping comes in.
Despite the name, zero gravity does not mean floating or sleeping in space. It is simply a position created by an adjustable bed that gently raises your upper body and legs to support a more balanced posture.
In a typical zero gravity position, the head section lifts about 15° while the foot section rises about 35°, creating a relaxed V-shaped position where your knees sit slightly higher than they would on a flat mattress.
The goal is not to create a “perfect” sleeping position. It is to give your body another option—one that feels more supported than lying completely flat.
Zero Gravity Sleeping: Quick Answers to Common Questions
| You wanted to know | Short version |
|---|---|
| Is this a different kind of bed? | No. Zero gravity is a position, not a separate type of bed. An adjustable bed simply raises the head and feet together to create a gentle V-shaped posture. |
| What do the 15° / 35° numbers mean? | These numbers describe the typical zero gravity position on an adjustable bed. The head section lifts about 15° while the foot section rises about 35° to create a more balanced and supported posture. |
| Do I have to use the Zero Gravity button? | No. You can create a similar position by adjusting the head and foot sections manually. The Zero Gravity button simply moves both sections together with one touch. |
| Then what’s Anti-Snore? | A head-only raise designed for a more elevated pillow-like position. |
| Can I sleep in Zero Gravity all night? | Some people enjoy sleeping in this position overnight, while others prefer using it while relaxing before sleep. Side sleepers, partners who prefer a flat surface, or those with specific comfort preferences may prefer other positions. |
What the Position Actually Is
Zero gravity sleeping is not about floating or removing gravity. It is simply a more supported way to position your body on an adjustable bed.
In this position, the head section gently lifts while the foot section rises, creating a relaxed V-shaped posture. Your knees naturally bend, and your legs sit slightly higher than they would on a completely flat mattress.
The idea behind this position comes from NASA’s research on Neutral Body Posture—the natural shape the human body takes when it is relaxed and not pushing against a flat surface. Adjustable beds adapted this concept into an everyday comfort position, giving people another way to customize how they rest.
You may see different angle numbers mentioned online, because there is no single universal measurement for zero gravity. Some sources describe slightly different angles, but the goal is the same: creating a gentle V-shaped position that feels more balanced and supported.
Keep in mind that an adjustable bed can move far beyond the zero gravity position. Hold the head-up or foot-up button longer, and you can create other comfortable positions for reading, watching TV, or relaxing before sleep.
Understanding the Buttons on Your Adjustable Bed Remote
The Zero Gravity button is the easiest way to find this position. With one touch, it raises the head and foot sections together to create the gentle V-shaped posture we described earlier.
The Anti-Snore button works differently. It only lifts the head section, creating a slightly elevated sleeping position similar to adding a little more height under your pillow. It does not raise your knees or legs.
The Memory button lets you save the position that feels best for you. If the preset Zero Gravity position feels a little too high or too low, simply adjust the head and foot sections to your preferred angle and save it for easy access later.
The Flat button brings the bed back to a completely level position when you are ready to return to a traditional sleeping surface.
Of course, you do not have to use any preset at all. The head-up and foot-up buttons give you full control, allowing you to create a position that matches the way you relax, read, watch TV, or sleep.
What It Changes, and What It Does Not
A zero gravity position changes the way your body rests on the mattress. By gently raising your legs and supporting your upper body, it creates a more balanced posture compared with lying completely flat. For many people, this different position simply feels more comfortable because the body is supported in a new way.
But comfort is different from treatment. Zero gravity is not a medical solution, a circulation therapy, or a replacement for guidance from a healthcare professional. It is simply another way to adjust your sleeping position and discover what feels right for you.
If your main goal is reducing nighttime snoring or creating a more elevated sleeping angle, a head-only raise may be a better place to start. Try the Anti-Snore button or use the head-up button to create a higher pillow-like position without lifting the legs.
You may also see the term “zero gravity” used on some lift chairs. Same nickname, different furniture.
An adjustable bed keeps and supports your mattress while changing your sleeping position. A lift chair is designed for sitting, reclining, and helping you move from sitting to standing. If you are deciding between the two, our guide on Lift Chair vs Adjustable Bed: Which One Fits Your Needs? can help you understand the difference.
When It Helps, and When to Skip It
Zero Gravity may be worth trying if you enjoy relaxing on your back with your knees slightly elevated, or if you like having a more supported position while reading, watching TV, or winding down before sleep.
You may prefer another position if you are a side sleeper throughout the night, you only need your head elevated, or your partner prefers a completely flat sleeping surface.
Bed size also matters. On a standard King adjustable base, the entire mattress moves together. If one person wants to use the Zero Gravity position while the other prefers a flat surface, a Split King setup—two Twin XL adjustable bases placed side by side—offers more flexibility.
During later pregnancy, some people may need to be more mindful of sleeping positions. Because Zero Gravity places the body in a reclined, back-supported posture, it is best to follow the recommendations from your healthcare provider and choose the position that feels most comfortable and appropriate for your needs.
Where It Lives on Our Remotes
The Zero Gravity key and the Anti-Snore key are on both remotes we ship now: the T600 Premium and the E300.
Size, clearance, and whether the mattress bends still come first. See how to choose an adjustable bed frame. Neither key fixes a base that will not go in the frame.
If you keep holding the head-up key, you can reach sit-up range: 65° on the T600, 60° on the E300. That is not the pose.
Understanding the Zero Gravity Controls
The Zero Gravity and Anti-Snore buttons are available on both of our current adjustable bed bases: the T600 Premium and the E300.
Before choosing an adjustable base, it is important to make sure the rest of your setup works with it. Consider the bed size, available space, clearance requirements, and whether your mattress is flexible enough to adjust with the base. For more guidance, see our guide on How to Choose an Adjustable Bed Frame.
The Zero Gravity position is designed as a relaxed, supported posture-not a sitting position. If you continue holding the head-up button, the bed can move into a more upright angle for activities like reading or watching TV, reaching up to about 65° on the T600 Premium and 60° on the E300.
That is a different position-not Zero Gravity.
Is Zero Gravity the Right Position for You?
Before choosing the Zero Gravity button, check a few things:
- You want your head and legs raised together-not a reading position and not just a higher pillow angle.
- You have tried the preset Zero Gravity position first. If the standard setting does not feel quite right, adjust the head and foot sections and save your preferred position with the Memory button.
- You use Anti-Snore when you only need head elevation. If your goal is simply a higher pillow-like position, raising the head section alone may be the better choice.
- You considered your partner’s preferences. On a shared adjustable base, one side’s movement affects the entire mattress. A Split King setup allows each person to adjust their own side independently.
- You choose the sleep position that fits your needs during pregnancy. If you are in later pregnancy, follow the recommendations from your healthcare provider and select the position that feels most comfortable.
- You understand that Zero Gravity is a feature, not a separate type of bed. You do not need to shop for a special “zero gravity bed”—you are looking for an adjustable bed with the right positioning options.
Zero Gravity Sleeping: Frequently Asked Questions
What is zero gravity on an adjustable bed?
Zero Gravity is a preset position that raises the head and foot sections together, creating a gentle V-shaped posture. On our adjustable bases, the Zero Gravity position lifts the head section at about 15° and the foot section at about 35° to create a more supported resting position.
Is a zero gravity bed different from an adjustable bed?
No. Zero gravity is one pose. The bed is the base that can hold it. You do not need a second product labeled "zero gravity bed."
Does zero gravity help your back?
Many people find Zero Gravity feels different from lying completely flat because the body is positioned in a more supported way. However, comfort is personal, and Zero Gravity is not a medical treatment or a replacement for advice from a healthcare professional.
How is Anti-Snore different from Zero Gravity?
Anti-Snore creates a more elevated pillow-like position by lifting only the head section. Zero Gravity raises both the head and foot sections together to create a more balanced V-shaped posture.
Can I sleep in zero gravity all night?
Some people enjoy sleeping in this position overnight, while others prefer using it while relaxing before sleep. The most comfortable position depends on your sleeping style and personal preference.
Use the Remote You Already Have
Think of Zero Gravity as a starting point—not a separate type of bed. The preset creates a gentle V-shaped position by raising the head and foot sections together. If the preset does not feel quite right, adjust the angles to match your comfort and save your favorite position with the Memory button.
Use the Anti-Snore button when you only want to raise your upper body without lifting your legs.
You do not need to shop for a separate “zero gravity bed” to get this feature. Zero Gravity is simply one of the many positions available on an adjustable bed. If your mattress is compatible, your room setup allows for it, and a shared sleeping position works for both partners, explore our adjustable bed frames to find the right fit.
