Zero Gravity Bed: What Are They & What Are the Benefits?

October 22, 2021 | Casper Editorial Team

You might think your traditional bed is comfortable, but it may also be the source of your neck and back pain. Dreaming of a solution to those daytime aches and pains? When it comes to getting a restful night’s sleep and eliminating pain, a zero gravity bed is the best answer. 

But, what is a zero gravity bed? 

A zero gravity bed is any adjustable bed frame that places your body into a zero gravity position. This spreads the pressure evenly throughout your body to alleviate neck and back pain. Plus, it can benefit a sleeper’s digestion, breathing, and provide proper blood circulation.

Keep reading to learn more about this type of bed and how it can provide you with better sleep.

Enjoy a better night’s sleep with the Zero Gravity features on our adjustable bed frames. Relieve stress on your body and relax comfortably through the night with a zero gravity bed.

What is a Zero Gravity Bed?

When you hear “zero gravity,” images of astronauts floating in space are probably the first to come to mind. Well, that’s what a zero gravity bed promises: the feeling of floating in space without having to actually be in space.

NASA invented this zero gravity position to ease the stress on astronaut’s bodies from launching into space. Now, you can experience that pressure-free feeling for yourself with a zero gravity bed. 

On an adjustable bed base, the zero gravity feature places your body in a neutral sleeping position. With your legs raised and head tilted up, it supports your heart, spine, and nervous system and makes it easy to fall and stay asleep. 

What Does Zero Gravity Position Mean?

Your sleeping position at night can have a profound effect on whether you wake up feeling rested or wake up with a new ache. So, the best position to sleep in is the one that supports every part of your body from your head to your toes. 

Wondering how a zero gravity bed can help you achieve this position? Here’s how these programmable positions works:

  • Your upper body is raised to a 120-degree angle so that your head is above your heart
  • Your legs are elevated to about 45 degrees, with knees bent
  • Your torso and thighs are angled equally from the hip

The Top 5 Benefits of Zero Gravity Beds

Gravity weighs us all down. The benefit of a zero gravity bed is the pressure relief you will experience on our bodies during the hours when we need it the most. As you sleep, your body can fully rest and recover in the most relaxing position. 

Whether you’re suffering from back pain or looking for an alternative sleep setup to catch more Zs, anyone can benefit from the zero gravity sleeping position. Take a look below at their top five benefits.

#1 Ease Neck and Back Pain

In the zero gravity position, your spine is relieved of all tension and pressure. 

When you’re sleeping in a flat position, gravity adds pressure to your spine and causes discomfort and soreness. You’re likely to feel this pain in your neck and lower back. And if you already have sleeping problems, this pain can feel even worse.1 That’s because studies show that sleep disturbances interfere with how your body manages pain. The less restful your sleep, the less opportunity your body has to try to alleviate those aches. 

Being in a sleep position that fully aligns your spine is the solution to your pain. The 120-degree angle guarantees that you’ll wake up pain-free. 

#2 Improve Digestion

Placing your upper body in the zero gravity upright position helps you to digest food properly, preventing sleep disruptions. 

When lying flat, gravity works against your digestive system. The body then has a harder time breaking down food. Your digestive system has already slowed down for the night, so a poor sleep position forces it to work harder. 

This means you’re more likely to experience sleep disruptions like:2

  • Heartburn
  • Indigestion
  • Acid reflux

When poor sleep causes digestive issues, those issues lead to more poor sleep. It’s a cruel cycle, but at a 120-degree angle, gravity works with your digestive system. Food is better able to move through your body allowing you to sleep easily.

#3 Eliminate Snoring (and Deepen Sleep)

Breathing better means sleeping better. But if you have trouble breathing at night or if your snoring is keeping you up, changing your sleep position can help open your airways. 

The zero gravity position that keeps your head and chest up at an angle allows for your nasal passages to stay open and keeps your tongue from putting pressure on your throat. In this position, you can experience a deeper, more restful sleep.

When Snoring Becomes a Nightmare 

Snoring problems are a lot more common than you may think.3

  • Roughly 40% of men snore habitually
  • About 24% of women snore habitually
  • About half of all people experience snoring at some point in their lives

But when snoring becomes bad enough to disrupt the amount of sleep you’re getting and the quality of that sleep, it’s time to make a change. 

Not only does poor sleep lead to daytime fatigue, but it also affects other crucial aspects of how your body functions. In fact, poor sleep can cause problems like:4

  • Impaired memory
  • Diabetes
  • Depression
  • Weak immune system
  • Lack of alertness
  • Heart diseases
  • High blood pressure

Some adjustable mattress bases, such as the Casper Rise Pro and Rise Max, even come with anti-snore features that work to reduce pressure on your airway. This makes it easier to breathe and reduces the possibility of any snoring waking you up.

#4 Regulate Blood Circulation

Elevating your legs so that they’re about the level of your chest is an easy exercise for proper blood circulation. This is because when you lie flat on your back, you put pressure on your heart, forcing it to work harder to pump blood throughout the body. 

With your legs lifted, you receive better blood flow, which is beneficial for reducing:

  • Swelling in the hands and feet
  • The chance of blood clots
  • Heart-related diseases

#5 Improve Heart Health Through Better Sleep

Not getting enough sleep can negatively impact your heart health, leading to the development of different heart-related issues, such as high blood pressure and heart failure. With a zero gravity bed, you can ensure you’re getting the most restful sleep possible for your body. 

What’s the optimal amount of time spent snoozing? 

A good rule to follow is seven to eight hours of sleep each night.5 While it can vary a little, you’ll know you’re reaching your body’s ideal sleep duration if you’re able to fall asleep in 15 minutes and wake up feeling rested without an alarm. 

If you’re looking for more ways to improve your sleep quality and your heart health, Hopkins Medicine recommends:

  • Reporting to your doctor for any sleep or heart concerns
  • Seeking treatment for any underlying sleep-related problems
  • Maintaining a healthy weight

The Best Position to Sleep In For Zero Gravity Beds

There are a few sleep positions to choose from, but sleeping on your back is best for zero gravity beds. It guarantees spinal alignment and opens nasal passages.

In traditional beds, sleeping on your back may not be comfortable without a few pillows. Since the body is flat, gravity still puts pressure on the lower back or causes your nasal passages to close, leading to back pain and nasal congestion.6 

In a zero gravity bed, all of those problems are solved because you’re placed in an upright position. You won’t need to add a ton of extra pillows or toss and turn all night until you find that sweet spot. With an adjustable zero gravity bed, you can find that sweet spot sooner. And with the Casper Rise Adjustable Base, you can save that sweet spot using a programmable memory button. 

The Best Mattress for a Zero Gravity Bed

If you’re thinking of making the switch to zero gravity, it’s important to consider which mattress is best for your adjustable base. In particular, your zero gravity mattress has to be flexible enough to match the bends of the base without damaging it. 

The best options are:

The Price of a Good Night’s Sleep

The cost for a zero gravity bed depends on a variety of factors. Prices can range anywhere from $300 to $10,000 or more.7

It’s a pretty wide range, but there are a number of considerations that can influence the price: 

  • Buying an adjustable bed frame with the zero gravity feature may mean buying a new mattress to go along with it, increasing your total cost.
  • The more advanced the features are, the more you’ll have to pay for the base. 
  • The bed size can also affect the price.  

At the end of the day, it’s all about finding the best option for you and your budget.
