What Is a Zero Gravity Bed And Its Benefits?

By: Christina Davies
Updated on: April 05, 2024

In today’s fast-paced world, getting a good night’s sleep is important for our overall health and well-being. One emerging trend in the sleep industry is using zero-gravity beds, which offer a unique sleeping experience that can provide numerous health benefits. This article will explore the concept of a zero gravity bed, how they work, and their advantages for your sleep and overall health.

What is a Zero Gravity Bed?

The term “zero gravity” refers to a neutral body posture that NASA initially developed to help astronauts during takeoff. In this neutral position, the body is in a state of weightlessness, with the head and feet slightly elevated above the heart and stomach. This angle of approximately 120 degrees is considered the most relaxed position for the heart and nervous system.

Zero gravity beds are designed to replicate this position and offer a weightless sensation while you sleep. These beds are typically adjustable, allowing you to raise both the head and foot of the bed to achieve the desired angle. By elevating your body on a flat bed in this way, zero gravity beds distribute your weight evenly and prevent pressure build-up on any specific body part.

The Benefits of Zero Gravity Sleep Position

Sleeping in a zero-gravity position can benefit your sleep and overall health. Let’s explore some of the advantages of zero-g sleep position:

Minimizes Pain

Pain relief is one of the main advantages of sleeping in a zero-gravity position. When you lay flat on a traditional mattress, there can be a gap between your body and the mattress, causing pressure on certain muscles and joints. In contrast, the benefits of a zero-gravity position ensure there is no gap, promoting better posture and distributing your body weight evenly. This can help alleviate pain, particularly in the neck, back, and joints.

Improves Circulation

Elevating your legs and feet in a zero gravity position promotes better blood circulation. This can benefit individuals who experience swelling or edema in these areas. Sleeping in zero gravity beds can reduce the risk of deep vein thrombosis and varicose veins by improving circulation.

Enhances Digestion

Sleeping in an inclined position can improve digestion compared to sleeping flat. This can lead to a healthier gastrointestinal tract and help prevent issues such as acid reflux and heartburn. A well-functioning digestive system promotes better sleep and overall well-being.

Reduces Snoring and Sleep Apnea

Sleeping on your back can make you snore and even cause sleep apnea because it relaxes your tongue and jaw, which can block your airways. However, sleeping in a zero gravity position with your upper body elevated helps keep your airways open and reduces the symptoms of snoring and sleep apnea. This can result in quieter and more restful sleep for both you and your sleep partner.

Alleviates Pressure on the Heart

When you sleep in a zero gravity position, your heart has less pressure. This allows your heart to pump blood more easily, improving blood flow and promoting better heart health. By high blood pressure and reducing the strain on your cardiovascular system, sleeping in a zero gravity bed can benefit your overall cardiovascular health.

Relieves Pregnancy Symptoms

Pregnant women often experience discomfort during sleep due to back pain, heartburn, and edema. Sleeping in a zero gravity position can make you feel better by removing pressure from your lower back and improving your blood flow. It can provide pregnant women with a more comfortable and restful sleep.

Enhances Relaxation and Deeper Sleep

The zero gravity sleeping position is known for its ability to promote relaxation. By relieving pressure on your body and creating a weightless sensation, sleeping in a zero-gravity bed can help you unwind and achieve a deeper state of relaxation. This can help you sleep better and feel more refreshed.

Offers Versatility and Customization

Adjustable beds supporting the zero gravity position often have additional features to enhance your sleep experience. These features may include massage functions, under-bed lighting, built-in USB ports, and programmable remotes. With the ability to customize your bed to find the most comfortable position for sleep, the gravity bed benefits you can create a personalized sleep environment tailored to your unique needs.

Improves Overall Sleep Quality

Combining all the benefits mentioned above, sleeping in a zero gravity position can significantly reduce pressure and improve overall sleep quality. From pain relief and enhanced circulation to reduced snoring and relaxation, zero gravity beds provide an optimal sleep environment to help you wake up refreshed and rejuvenated.

How to Use a Zero Gravity Bed

Using a zero-gravity bed is relatively simple. You can activate the position with a single click if you have an adjustable bed with a zero gravity preset button. Alternatively, you can manually adjust the bed to achieve a zero g position at the desired angle. Ideally, your torso and thighs should be at a 120-degree angle, with your knees slightly bent and raised above heart level.

It’s important to note that sleeping in the zero gravity position is most effective when you sleep on your back. Some adjustable beds have extra features for side or stomach sleepers, but the zero gravity position is made to give the best support and comfort when you sleep on your back.


How do you use a zero-gravity bed?

You can achieve the zero gravity position on your adjustable bed in two ways: using a preset button or manually adjusting the adjustable bed frame’s angles. Some adjustable bed models come with a convenient remote button that instantly positions the head and foot of the mattress in the zero gravity position.

If your bed doesn’t have this preset button, you can still set it up easily. Simply raise the bed sections so your head and knees are slightly above your heart. Some remote controls even allow you to save a couple of favorite sleep positions beforehand, making it effortless to return to the zero gravity position whenever you prefer.

Should I use a pillow with zero gravity?

People who sleep can try using or not using a pillow to see what feels more comfortable. However, it’s usually a good idea to sleep with a pillow. Pillows are often needed to support the space between your neck and the mattress. Sleeping without a pillow might make your neck feel stiff or hurt when you wake up. If you find a regular pillow uncomfortable when you’re in a zero-gravity position, you could consider using a small neck pillow instead.

Is sleeping in a zero-gravity position okay?

Absolutely, sleeping in a zero gravity position can be quite comfortable as it reduces pressure on your body. This position can also enhance your breathing and blood circulation, offering various benefits. However, it’s worth noting that sleeping on a flat surface is also perfectly fine. Adjustable beds are great because they allow you to experiment with different angles and find your ideal no-gravity sleeping position.

Can you attach a headboard and footboard to a zero-gravity bed?

Yes, you can usually attach a headboard and footboard to an adjustable bed frame. Many adjustable bed models come with headboard brackets, making them easy to set up. Alternatively, you can consider wall-mounting an adjustable base and a headboard for a more traditional bed frame appearance.

How long does it take to get used to a zero-gravity bed?

Most people typically get used to sleeping on an adjustable bed for several days to a week. This adjustment period is common and doesn’t necessarily mean that the adjustable zero gravity bed isn’t unsuitable. It’s similar to adapting to a new mattress, even if it’s a perfect match for your sleeping style.


Zero gravity beds offer a unique sleeping experience that can provide numerous benefits for your sleep and overall health. By mimicking the neutral body posture developed by NASA, these adjustable beds allow you to sleep in a weightless position that promotes pain relief, improved circulation, better digestion, reduced snoring, and enhanced relaxation. With the ability to customize your bed and create a personalized sleep environment, zero gravity beds can significantly improve your overall sleep quality. Consider investing in a zero-gravity bed to optimize your sleep and wake up feeling rejuvenated each morning.
