Mattress Store Near You With Mattresses and Adjustable Bases

Are you struggling to find a comfortable sleep position that alleviates your aches and pains? The zero gravity sleep position might be the solution you’ve been searching for. This unique sleep position, inspired by the way astronauts rest in space, is designed to distribute your body weight evenly, reducing pressure on your joints and spine. In this article, we’ll explore the concept of zero gravity sleep, its numerous health benefits, and provide practical tips on how to achieve this position for a more restful and rejuvenating night’s sleep.

If you wake up sore in the morning or tired, you probably mention it to your friends or coworkers. Everyone has a little advice or way to help you sleep better at night.

You may have heard someone mention the idea of a zero-gravity bed. Of course, you’ve never heard of this and wonder if it might help you get a better night’s sleep.

Take it from your favorite astronaut – developing the zero gravity sleeping position is one of the best things NASA has done for humanity since, well… at least since the memory foam mattress.

Find out how you can benefit from a zero-gravity adjustable bed frame and where you can get this spectacular piece of technology in this guide to zero gravity.

Fair warning – this guide will NOT teach you how to walk on the moon (or moonwalk for that matter.)

What Is Zero Gravity?

You’ve known about gravity since you were in elementary school and learned about the guy who got hit in the head with an apple. Gravity is what keeps on the earth. Of course, this constant pull on your bones and joints causes your body to age and become achy in all the wrong places.

A true state of zero gravity means the state of weightlessness experienced during a change in gravitational fields. As a space shuttle travels and changes speed in its orbit of the Earth, its centrifugal force balances the Earth’s gravitational pull – an absolute necessity to remain in orbit instead of getting drawn back towards the Earth. The result? The weightless state astronauts know as zero gravity.

While astronauts experience zero gravity while in space, during the actual liftoff and exit from the Earth’s atmosphere, they’re subjected to ridiculous amounts of gravitational force. In fact, they experience as many as 3 Gs on their way into the great beyond – that’s three times what you and I experience in our beds at home. This pressure can be harmful to the body, and it’s why NASA developed a neutral body posture known as the zero gravity position designed to provide maximum comfort for astronauts during these stressful periods.

The concept of zero gravity sleep is inspired by the natural resting position of astronauts in space, where they experience weightlessness. In this position, the body reclines at an angle that minimizes the force of gravity, allowing for even distribution of body weight and reducing pressure on the spine and joints. But what exactly is the definition of zero gravity sleep?

The definition of zero gravity sleep refers to a sleep position where the body is reclined at an approximate 120-degree angle, with the legs elevated slightly above the level of the heart. This position promotes a neutral spine alignment, reducing the strain on the lower back and hips. It also encourages better blood circulation and minimizes the risk of developing conditions like sleep apnea and acid reflux.

In the following sections, we will delve deeper into the benefits of zero gravity sleep, address common concerns, and provide practical tips on how to achieve this optimal sleep position for a more comfortable and restorative night’s rest.

Why Should I Care About All This Science? And What Does It Have to Do With My Bed?

We’re getting to that. As with most of NASA’s best technology, other companies began to think of how we everyday humans could benefit. Soon, manufacturers realized that many of us experience the more unfortunate side effects of gravity in the form of painful pressure points throughout the body, and could benefit from the same positioning NASA astronauts used on liftoff.

What Is The Zero Gravity Sleep Position?

While most people can’t reach zero gravity, you can sleep in a zero-gravity position. This helps to remove the stress and pressure on your body while you sleep.

The zero gravity position was originally created to help astronauts heading into space. Needless to say, it adds a lot of stress to the body to rocket into space, so NASA created the zero gravity position for astronauts to assume for liftoff. This position helps to minimize the pressure that astronauts feel on their spine during lift off.

To truly assume the zero gravity position you have to make sure your:

  • Torso and thighs are at equal angles from the hip.
  • The upper body is elevated.
  • Knees are bent.
  • Legs are raised to about chest level.

Not easy to do in a traditional bed, unless you’re a throw pillow collector – and even then, pillows are bound to shift at night just as you do.

Instead, the geniuses behind the first adjustable bed base realized that the bed itself must support the zero gravity position and right they were. Once the entire body is relaxed and conforms to a high-quality zero gravity mattress… that’s when the magic truly happens.

Is it Okay to Sleep in Zero Gravity Position?

As the zero gravity sleep position gains popularity, many people wonder about its safety and whether it’s okay to sleep in this position. Let’s address some common concerns and answer the question: “Is it OK to sleep in zero gravity position?”

In general, the safety of zero gravity sleep position is not a cause for concern for most individuals. In fact, this position can provide numerous health benefits, such as reduced pressure on the spine and joints, improved circulation, and alleviation of conditions like sleep apnea and acid reflux. However, it’s essential to listen to your body and consult with your healthcare provider if you have any existing medical conditions or concerns.

For pregnant women, it’s recommended to consult with a healthcare professional before adopting the zero gravity sleep position, as the ideal sleep position during pregnancy may vary based on individual needs and stages of pregnancy.

People with certain medical conditions, such as glaucoma or heart issues, should also consult their healthcare provider before trying the zero gravity sleep position, as elevating the legs and upper body may not be suitable for everyone.

In conclusion, the safety of zero gravity sleep position is generally not a concern for most individuals. However, it’s essential to consider your unique health needs and consult with a healthcare professional if you have any concerns or existing medical conditions.

What are the benefits of sleeping zero gravity?

OK, maybe it’s not really magic – after all, we did just spend time explaining the science behind it all. However, doctors, sleep experts, and customers alike have been bragging on the health benefits of zero gravity sleep since NASA first came up with the idea – and at least some of them might just be magicians. Regardless, as it turns out, the health benefits truly do seem a bit magical.

Here are a few things to consider:

Deeper Sleep and Easier to Fall Asleep

According to NPR, around 60 million Americans are affected by insomnia each year. While sleeping in a zero-gravity position isn’t guaranteed to solve insomnia, it can help you relax more effectively. You remove pressure on your joints and muscles in this position and places your spine in a comfortable position. With the stress taken off your body, you’ll find that you sleep more deeply than you did lying flat.

Pain Relief: Helps Relieve Neck and Back Pain

80% of adults experience neck or back pain at some point in their lives.


When you lie in a flat position on a traditional mattress, there are gaps between your body and the mattress in places. The places that do touch the mattress absorb the stress of the places that aren’t touching. This can leave you with a crick in your neck and unexplained back pain in the morning.

When you sleep in the zero-gravity position, the weight of your body is more evenly spread out. Also, your spine is in a stress-free position. This helps you relax and also keeps you from waking up achy in the morning. Who doesn’t like waking up without aches and pains?

Breathe Easy and Snore Less

Up to 20-40% of the general population snore on a regular basis.


If you snore or you have a partner that snores, you know what a problem it can be even if it isn’t associated with sleep apnea. There are many causes for snoring and not all of them can be helped with a zero-gravity position but some can.

If you snore because of the position of your tongue or unusual pressure on the throat, then the zero-gravity position can help curb your snoring. In the zero-gravity sleep position, your head is at a 30 to 45-degree angle. This helps to relieve pressure on your throat. Your airways are more open, and this means that you breathe easier and snores less.

The angle of your head in this sleep position can also settle your tongue in a more normal position. If you want to breathe easier and snore less, you need to try the zero-gravity position on your adjustable bed.

Better Circulation

With your legs slightly raised, the blood flows more easily through your body. This provides a lot of health benefits. With better circulation, you’ll find the following benefits:

  • A reduction in swollen hands and feet
  • Faster healing
  • Reduces the chance of blood clots
  • And more

Your doctor may recommend the zero-gravity bed position if you have heart disease, diabetes, or challenges with high blood pressure. When you’re sleeping in this position, your blood circulates more easily, and it also helps blood flow more easily through your heart muscle.

Better Digestion

When you sleep at night, your bodily functions slow down, which is why you should only eat a light snack late at night. Of course, another reason for slower digestion is because when you lie flat, it can cause problems with digestion. This can cause problems falling and staying asleep.

However, in the zero-gravity position, the upper party of your body is higher than your stomach. This allows your body to digest food normally. It can help you fall asleep faster and stay asleep. When you’re properly digesting your food, you may find it easier to lose weight, feel more energetic, and help your overall mood.

Reduced Occurrences of Heartburn (Acid Reflux)

There is nothing worse than waking up with heartburn and acid reflux. When you sleep in a traditional position, acid can easily come up from your stomach without gravity to keep it in place. The beauty of sleeping in an elevated position is that your head is above your stomach and the acid stays there.

The Art of Sleeping in Zero Gravity: Pillows and Beds

Achieving the zero gravity sleep position may seem challenging, but with the right setup and support, it can be easily attained. In this section, we’ll answer the questions: “How do you sleep in zero gravity position with pillows?” and “How do you sleep in zero gravity position on a flat bed?”

How to use pillows in zero gravity position

Pillows for zero gravity sleep position play a crucial role in providing the necessary support and comfort. To achieve the desired position:

  1. Place a firm pillow or wedge under your knees to elevate your legs slightly above your heart level.
  2. Use a contoured or cervical pillow to support the natural curve of your neck.
  3. Place a small lumbar roll or cushion behind your lower back for additional support and to maintain the natural curve of your spine.

How to sleep in zero gravity on a flat bed

While adjustable beds make it easier to achieve the zero gravity position, it’s still possible to create a similar setup on a flat bed. Here’s how:

  1. Stack pillows or use a foam wedge to elevate your upper body at an angle of about 30–45 degrees.
  2. Follow the same pillow arrangement as mentioned above for leg, neck, and lumbar support.

Cons of Sleeping in Zero Gravity Position

While the zero gravity sleep position offers numerous benefits, it’s essential to consider potential disadvantages to maintain a balanced view. So, what are the disadvantages of zero gravity sleep?

  1. Cost: Investing in an adjustable bed or specialized pillows and wedges to achieve the zero gravity position can be expensive for some individuals.
  2. Adaptation period: It may take some time for your body to adjust to this new sleep position, resulting in initial discomfort or difficulty falling asleep.
  3. Limited mobility: Sleeping in the zero gravity position may make it more challenging to change positions during the night, which could be an issue for those who tend to toss and turn.

Despite these potential downsides, many people find that the benefits of zero gravity sleep outweigh the disadvantages, leading to a more comfortable and restorative sleep experience.

Best Mattresses for Zero Gravity Sleep

Choosing the right mattress is crucial for achieving the perfect zero gravity sleep position. The ideal mattress should provide ample support while conforming to your body’s natural curves. Here are some types of mattresses that work well for zero gravity sleep:

Memory foam mattresses: These mattresses contour to your body shape, providing excellent support and pressure relief. They’re particularly suitable for zero gravity sleep as they help maintain proper spinal alignment.

Latex mattresses: Latex offers a balance of support and pressure relief, making it another great option for zero gravity sleep. It’s also a more breathable material, which can be beneficial for those who sleep hot.

Hybrid mattresses: Combining the best of both innerspring and foam, hybrid mattresses offer a blend of support, pressure relief, and responsiveness. This makes them suitable for zero gravity sleep, as they can adapt to the body’s changing positions throughout the night.

Zero Gravity Sleep for Specific Conditions

The zero gravity sleep position can be particularly beneficial for those suffering from specific conditions, such as back pain and snoring.

Zero gravity sleep for back pain: By promoting a neutral spine alignment, the zero gravity position can help alleviate pressure on the lower back, reducing pain and discomfort. It also allows for better weight distribution, which can help relieve pressure points and prevent further strain on the back.

Zero gravity sleep and snoring: Snoring is often caused by restricted airways during sleep. Elevating the upper body in the zero gravity position can help open up the airways, reducing the risk of snoring and improving overall sleep quality.

The Science Behind Zero Gravity Sleep Position

To better understand the benefits of zero gravity sleep, let’s take a closer look at the science behind this sleep position. The zero gravity sleep position is designed to mimic the weightless conditions experienced by astronauts in space. In this environment, the body naturally assumes a slightly reclined position with the legs elevated, as it allows for even distribution of body weight and minimal strain on the spine and joints.

This position has been found to promote better blood circulation, as the heart doesn’t have to work as hard to pump blood against gravity. It also helps reduce the risk of developing conditions like sleep apnea and acid reflux, as the elevated upper body allows for easier breathing and prevents stomach acid from flowing back into the esophagus.

By understanding the science behind zero gravity sleep position, it becomes clear why this position can offer numerous health benefits and contribute to a more comfortable and restorative sleep experience.

Sleeping In Zero Gravity Position

Heard enough about the advantages of zero gravity? Ready to dive into the best night of sleep you’ve had since… ever? Here’s how to capture all the benefits of zero gravity for yourself.

  • First, you’ll need a zero gravity adjustable bed base that’s movable at the head and the foot. (Note: No Bull Mattresses and More sells multiple styles in our online shop as well as at each of our warehouse locations.)
