Zero Gravity and other ways to recline your chair


Most people associate massage with lying down, however, traditionally understood lying down is not always required for a massage. In massage chairs, massages are performed in several different positions. There are, of course, chairs that massage in a lying position, in the Zero Gravity position, there are non-reclining models, and those in which only the footrest “reclines”. Below, you will learn how massage chairs “recline” and how this affects the massage.


In massage chairs that do not recline, the massage is performed in a sitting position. These are most often models of compact sizes, which offer basic massage and can easily fit in any room. Often, such a chair (in our offer, for example, Massaggio Piccolo) is one of the choices for people who do not have enough space. Another proposition from our offer is iRest QL (A185) – a non-reclining chair, however, possessing a unique tilting function and a comfortable, detachable footrest. Another example are chairs with non-reclining backs but with an adjustable footrest. The back massage is performed in a sitting position, while legs can be stretched out to enjoy a relaxing massage.


In our offer, reclining chairs to the Zero Gravity position predominate, but there are also those that recline to a lying position. The main advantage of compact – non-reclining – chairs over reclining ones is space saving. Non-reclining chairs, however, have fewer functions and are not as technologically advanced as reclining ones. A solution for people who want to opt for a chair with more functions, fearing it will take up much space, is Zero Wall function. This feature allows setting the massage chair only about 10 cm from the wall – that’s enough for it to be able to recline.


In massage chairs reclining to a lying position, the backrest is lowered down, and the footrest with leg massager goes up. During reclining, the process can be stopped at any moment, choosing the most comfortable position for oneself for the massage. However, keep in mind that the farther back you lie, the stronger the massage. Gravity simply does its job.

We should mention the Flat position featured in Fujiiryoki JP3000. It is also a lying position, but the chair’s construction has been specially shaped so that the body assumes a sleeping position. It also reclines to the Total Relax position, which helps optimize stretching effects.

Thanks to the unique, split guide –  iOpen, through which the massaging arms move in advanced models of iRest (from iRest Grandease (A550) and higher), these chairs can not only recline to Zero Gravity but also to the Flat position. iOpen allows for increasing the possibilities of stretching the entire body as well as deep relaxation of the back muscles, and the spine.


It is considered the most comfortable position for massage. Paweł explains what Zero Gravity is, what it entails, and what distinguishes it from other functions of massage chairs.

Zero Gravity is a natural body position in which the angle between the torso and thighs is approximately about 125 degrees, and the knees are raised to the height of the heart, resulting the most optimal relaxation of the whole body.

It is said that this position was scientifically confirmed by NASA researchers (hence its name) when they were looking for the ideal position for astronauts. However, this doesn’t change the fact that the massage chair reclining into the Zero Gravity position allows the back muscles to be thoroughly massaged. Until now the Zero Gravity position has appeared exclusively in the most complex and advanced chairs, such as Massaggio Stravagante 2 or Esclusivo 2, but we already have compact models, such as Massaggio Bello 2, which can boast this technology.


This is first of alli an exceptionally comfortable massage chair position,  which makes  the massage very pleasant and extremely relaxing, with the joints benefiting from the greatest relief. But the benefits of Zero Gravity can also include:

  • reduction of muscle tensions,
  • relieving pressure of the spine,
  • lowering blood pressure,
  • increased lung capacity,
  • better oxygenation of muscles,
  • reducing swelling.

The body positioning in Zero Gravity means that the heart does not have to pump blood against gravity, instead it freely distributes it throughout the body.

It’s worth mentioning that some models have several degrees of setting the chair in the Zero Gravity position, for example, iRest Chillin (A360) or Bodyfriend Davinci have 3 degrees to choose from.

What opinions about Zero Gravity do our customers have?

The chair is brilliant, the Zero Gravity feature makes you feel suspended in the air. A completely different feeling than a seated massage. I recommend!


Zero Gravity has one disadvantage, however. Because the backrest remains in a fixed position in relation to the seat, it’s not possible to perform a full-body stretch in this position. This programme is only available in chairs with flat type reclining. The airbags then grip the shoulders and calves, and the seat reclines to carry out the stretching programme. The Zero Gravity position only allows the legs to be stretched.

As you see, each of the ways of reclining the massage chair has its own benefits. It all depends on your needs, space availability and individual preferences. If you already know which one suits you best, take a look at our offer and if you have any questions after reading, feel free to contact us.


Paul, does every massage chair recline?

Unfortunately no. Not all of them. Let me explain.
The very basic models do not recline, some just have a footrest which can be moved up or down to support your legs. Others just have a movable backrest, but this is not a very comfortable position. However, most massage chairs do recline to a flat position, as if lying on a bed or to a Zero Gravity position.

What do you mean by Zero Gravity position?

Zero Gravity is also called the antigravitational position, which was developed during NASA research programs. People from NASA were looking for a perfect position for astronauts, who handle huge gravity loads during the launch of the ship into orbit. Zero Gravity became a game-changing discovery, and is still used in astronautics and many fields of biological regeneration.

So how does this work in a massage chair?

I would say that nowadays it’s a common feature of massage chairs. Zero Gravity function is primarily a position which your body takes while lying on the chair. Usually the parts of a massage chair recline separately, the seat stays stable, the backrest moves downwards, the foot-rest rises and your body becomes horizontal.

In models with Zero Gravity, the backrest and the seat recline together and your knees move to heart level, therefore creating a specific angle between your legs and your body. This makes it easier to promote blood circulation and release stiffness in your spine and linked body muscles.

That’s really interesting, so is this position healthier for your body?

Placing the body in the Zero Gravity position instead of a flat or sitting position means that the heart doesn’t have to pump blood in defiance of gravity and it is being freely distributed throughout the body. I would simply say that it is an incredibly cosy, comfortable and relaxing massage position. I should add, that it’s important to remember that in a reclined position, the body is pressed against the massager and so the massage received is more intense. So in the first few days, to avoid muscle soreness, you must be careful not to over-use the chair- especially in the reclined position.

Have I explained it clearly enough for you?

Yes, I can now see that Zero Gravity is a much needed function, and offers an even better massage session.
