Zero Gravity Sleeping Position: Benefits, Setup, and Why It Works

Have you ever wondered what is zero gravity or why more people are talking about zero gravity sleeping positions? Originally designed by NASA to reduce pressure on astronauts during lift-off, the zero gravity sleep position has made its way into everyday bedrooms through adjustable beds and ergonomic designs. It’s more than a buzzword—it’s a science-backed way to optimize sleep.

In this article, we’ll explore how to achieve the zero gravity sleep position, its benefits, who it’s best for, and how the right mattress and base can transform your rest.

What Is the Zero Gravity Sleep Position?

The zero gravity sleeping position involves reclining the upper body slightly (about 30–45 degrees) while elevating the knees so they rest above the level of the heart. This posture mimics the body’s neutral position in space, where gravitational pull is evenly distributed across joints and the spine.

Key features:

• Upper body reclined

• Knees elevated above heart

• Body forms a gentle “V” shape

This position is often activated through a preset on an adjustable bed labeled as “zero gravity movement.”

Benefits of the Zero Gravity Sleeping Position

Is zero gravity a good position to sleep in? Yes—and here’s why, broken down by benefit:

1. Spinal Pressure Relief

• Distributes body weight evenly

• Reduces compression on the lower back

• Promotes natural spine alignment

2. Improved Circulation

• Elevation of legs enhances blood flow

• Supports venous return and reduces swelling

3. Reduced Snoring & Sleep Apnea

• Keeps airways open by raising the head

• Minimizes soft tissue collapse in the throat

4. Acid Reflux Prevention

• Upper body elevation prevents stomach acid from traveling upward

• Ideal for people with GERD or digestive issues

5. Relief for Hemorrhoid Sufferers

• Elevating hips and reducing pressure eases discomfort

• Recommended sleep position for those with mild to moderate symptoms

6. Encourages Deeper Sleep

• Less tossing and turning due to pressure relief

• Muscle relaxation leads to improved sleep stages

Is It Safe to Sleep in Zero Gravity Position Every Night?

Can you sleep in zero gravity position long term? Absolutely. Many people adopt it as their default sleep posture.

Advantages of long-term use:

• Reduced morning pain and stiffness

• Fewer sleep interruptions

• Better sleep posture hygiene

However, some users—especially side sleepers—may need time to adjust or additional pillow support.

Zero Gravity Chair vs. Zero Gravity Bed

What does zero gravity chair mean?

• Recliner for daytime use

• Ideal for watching TV or reading

• Provides temporary relief from back pressure

Zero gravity bed:

• Designed for overnight sleep

• Controlled with an adjustable base

• Enables sustained spinal support and comfort

Key difference: Zero gravity beds are meant for restorative sleep, while chairs focus on comfort during sitting or resting hours.

Best Sleep Setup: Bed Base and Mattress

To enjoy full benefits, you’ll need the right components:

A. Adjustable Bed Base

• Includes “zero gravity” setting

• Remote-controlled elevation for head and feet

• Often comes with extras like massage functions

B. Compatible Mattress

• Flexible construction (memory foam or hybrid)

• Supports motion isolation and pressure relief

• Breathable materials for temperature control

✅ Recommended: EGOHOME Memory Foam Mattress

• Gel-infused, cooling memory foam

• Zoned support for spine and hips

• Designed for adjustable bed bases

• Fiberglass-free and hypoallergenic

This combination makes it easier to maintain a zero gravity sleep system safely and effectively.

Who Should Try the Zero Gravity Position?

The following groups can benefit most:

• Chronic back pain sufferers

• People with poor circulation (e.g., varicose veins)

• Individuals with snoring or sleep apnea

• Hemorrhoid sufferers

• Pregnant women (consult a doctor before trying)

• Anyone struggling with sleep quality

Final Thoughts

The zero gravity sleeping position is more than just a luxury—it’s a functional, science-supported approach to better sleep. If you're asking, “is zero gravity bed good for you,” consider your symptoms and comfort needs. Whether you're seeking pain relief, better circulation, or simply more restful sleep, this setup offers proven benefits.

By combining an adjustable bed base with a flexible, contouring mattress like the EGOHOME Memory Foam Mattress, you're not just improving sleep posture—you're investing in your overall well-being.
