Zero Gravity: what it is and which SIDORA chairs have it
Where this feature came from, how it works and which SIDORA chairs have it.
Author: Mykhailo Rybin
Short answer. Zero Gravity is a position with your legs slightly above your heart and your body weight spread evenly. Two Zero Gravity stages are offered by Imperio (UAH 728,000), Sentio Max (UAH 408,636) and Livaro (UAH 197,080); Miore and A70Max also have the feature.
Where the idea comes from
The “weightless” position comes from spaceflight: astronauts use it to withstand g-forces at launch. The backrest tilts back, the legs rise above heart level and the angle between torso and thighs opens up.
How it feels in the chair
Your weight spreads across the whole chair, pressure on the spine and joints drops and the back relaxes more easily. Rollers and airbags fit closer to the body, so the massage feels deeper.
One stage or two
Chairs with two stages offer a light recline and a deeper weightless position, so you can choose what feels best. Two stages are found in Imperio (reclines to 180°), Sentio Max (176° track) and Livaro.
Zero Gravity and stretching
In Sentio Max and A70Max, weightlessness is combined with Bi-Stretch programmes: the leg unit gently stretches the body from ankles to hips. After such a session you feel supple, as after a yoga class.
Who should consider it
People who sit or stand a lot and feel tired by evening, and anyone who wants to relax more deeply before sleep. A massage chair does not replace treatment: if you are pregnant, have serious health conditions or a pacemaker, consult your doctor first. More tips in how to choose a massage chair.
