After comparing specs, certifications, and thousands of owner reviews, the Saatva Classic ranks as the best zero gravity mattress for its dual-coil support and adjustable base compatibility; the Nolah Evolution is a strong alternative for pressure relief.
Sleeping in a zero gravity position, where your head and knees are slightly elevated, mimicking the neutral posture of astronauts during liftoff, can reduce pressure on the spine, improve circulation, and alleviate back pain. But not all mattresses support this position equally. We analyzed over 30 models based on CertiPUR-US and OEKO-TEX certifications, firmness levels, and aggregated owner reviews to find the best supportive options.
Our ranking prioritizes mattresses that maintain spinal alignment in a zero gravity reclined posture, distribute weight evenly, and have trial periods long enough to test the position at home. Owners report that a medium-firm feel with good edge support and minimal motion transfer works best for this sleep setup.

Frequently asked questions
What is the zero gravity position in bed?
The zero gravity position elevates your head and knees slightly above the heart, using an adjustable base to create a neutral spine alignment similar to astronauts at launch. This reduces pressure on the lower back and improves circulation.
What type of mattress is best for zero gravity?
A medium-firm mattress (around 5-7 on the firmness scale) with good support and minimal sag works best. Hybrids or innersprings with coils provide better support than all-foam, though high-density memory foam can also work for pressure relief.
Can any mattress be used in zero gravity position?
Most mattresses can be used with an adjustable base, but not all support spinal alignment. Avoid very soft or sagging mattresses as they can cause misalignment in zero gravity. Look for models with reinforced edges and zoned support.
How does zero gravity help with back pain?
By taking gravitational pressure off the spine, zero gravity reduces compression on discs and nerves. This can alleviate back pain, improve breathing, and enhance overall sleep quality.
What should I look for in a mattress for zero gravity?
Key features include medium-firm firmness, good edge support, motion isolation, and compatibility with adjustable bases. Certifications like CertiPUR-US and OEKO-TEX ensure safety and durability.
The verdict
The Saatva Classic is our overall best zero gravity mattress due to its durable coil-on-coil construction and excellent spinal alignment. For side sleepers, the Nolah Evolution offers superior pressure relief, while the Bear Elite Hybrid is ideal for hot sleepers seeking cooling performance.
