Adjustable beds are already a game changer for sleep, but the zero-gravity setting takes things to the next level.
Based initially on how astronauts recline during launch, this position has quietly become one of the most comfortable and effective ways to reduce pressure, improve sleep, and support the body.
What is Zero Gravity?
The "zero-gravity" position isn’t complicated. You’re slightly reclined, with your upper body lifted and your knees bent so your legs rest just above your heart. The result? Less pressure on your spine, improved circulation, and a feeling of weightlessness that many people describe as "floating".
Modern electric beds and lift chairs often include a one-button setting to get you there. No mucking around with pillows or awkward angles.
Why does it Feel Better for Your Body?
Lying flat is not for everyone. Your body usually requires support in precise areas if you have a backache, swollen legs, or circulatory problems. The zero-gravity position distributes your body weight evenly and allows your spine to relax without tension. It’s especially helpful if joint pain or arthritis keeps you from sleeping well.
It’s especially helpful for:
- People with tight lower backs or stiff shoulders
- Anyone who wakes up sore or swollen
- Those who need to take pressure off their joints at night
Better Breathing, Less Snoring
If you snore, have mild sleep apnoea, or just struggle to breathe comfortably lying down, elevating your upper body can help. The zero-gravity position naturally opens your airways and keeps the pressure off your chest.
Some people even find it helps with asthma or nasal congestion, especially during allergy season. If you’re curious what else to look for in a good bed, this guide might help.
Digestive Benefits as Well
Lying completely flat can sometimes cause reflux or indigestion, especially after dinner. With your torso slightly lifted in a zero-gravity position, gravity actually helps keep stomach acid down where it belongs.
A lot of people find it easier to sleep through the night without that burning feeling creeping up the throat.
Improves Circulation (and Eases Swelling)
If you’re someone who gets puffy feet or tight calves after a long day, or you’re managing conditions like diabetes or lymphedema, raising your legs can offer tangible relief.
The zero-gravity position lets blood flow more freely and helps reduce fluid build-up in the legs, ankles and feet. Here’s a deeper look at how it helps with swelling and fluid retention.
It’s like propping your legs up on the couch… but way more comfortable, and it actually stays in place all night.
More Comfortable During Pregnancy
In the later months of pregnancy, lying flat can feel impossible. The zero-gravity position can take pressure off your back, help with swelling, and support better breathing — all without needing a fortress of pillows. Many mums-to-be find it a lifesaver.
Just Better Sleep, Full Stop
Beyond all the medical bits, this position simply feels good. It reduces tension, supports natural curves in the body, and helps you fall into a nourishing, deep sleep faster and also stay asleep longer. Some people even take daytime naps in it because it’s that relaxing.
