Defying Gravity: Unlocking the Ultimate Gaming Experience with Zero Gravity Chairs

In this article, I would like to discuss another type of chair called zero gravity chair, which is marketed worldwide. It is characterized by optimal comfort and a sensation of weightlessness, immersing the user in a special universe, particularly suitable for gaming, providing long-term relaxation, and reducing discomfort compared to other classic types of ergonomic chairs. In this article, I aim to analyze or give an opinion on its specificity and technique simply to understand its explanation and justify the high cost of its purchase.

I believe most gaming enthusiasts, like myself, are familiar with the « Scorpion » chair model, designed to resemble a real scorpion belonging to this family. In fact, almost all chairs follow the same principle. At first glance, it is noticeable that it contains a special frame considered the main component, representing the basic structure of the chair and supporting the monitor through a folded frame in the form of a decorative arc, sometimes containing LEDs inside. The lower part of this chair appears more substantial, similar to car seats, suggesting that the designer utilizes the space under the chair down to the base to install various elements such as the motors for the chair’s tilting system, the footrest system, the folding system motors (typically DC motors for speed regulation), as well as spaces for electronic cards, optional batteries, and the actuators necessary for tilting, providing an optimal sensation of weightlessness.

Until now, I feel that there is a difference between classic ergonomic chairs and this type called zero gravity chair, due to differences in folding, tilting, and braking, which are based on electricity. On the other hand, gaming chairs are in manual mode, explaining partly the higher cost of these devices, taking into account good after-sales service in case of part replacement if necessary (such as motor brushes, plugs, buttons, LEDs, etc.).

In terms of the material used for the frame, it is often made of steel or aluminum, like other chair bases, offering strength and facilitating transportation. Of course, it also includes the classic elements of a gaming chair such as armrests, seat, footrest, and headrest, all padded to ensure long-term comfort.

Regarding the style, I notice that each designer targets a diverse clientele, ranging from modernity with a focus on colors and patterns to attract customers, to another elegant classic style offering traditional simplicity with elegant curves, while emphasizing functionality and gamer comfort.

Benefits of the Zero Gravity Chair

1- Weightlessness Sensation

To understand this point, it is necessary to know what the effect of gravity is. When sitting on a chair, everyone knows that there is a gravitational force exerted by the Earth that pulls us towards the ground. Without the chair, we would fall. Thus, the chair exerts another force against gravity to remain light, following the principle of interaction. The problem is that the force that keeps us from falling is applied to the chair’s surface, with a large part being absorbed by the spine and lumbar, causing significant muscle tension in the form of pressure and leading to pain over time in the shoulders, back, and lumbar. The first optimization found in all chairs is the tilting of the backrest to alleviate this tension, but in reality, it is not sufficient for optimal long-term comfort. That’s why the designer developed this type of chair to tilt completely. Physically speaking, this trick has two advantages for comfort:

Increased contact surface to generate a pressure gradient.
Distribution of mass to have a gravitational force gradient.

Historically, the principle of this chair was discovered a long time ago and developed by NASA. Recently, this principle has been used in many chairs such as spa chairs and dental chairs.

2- Good Blood Circulation

If we talk about ergonomics, we always talk about blood circulation, representing the movement of blood between the heart and blood vessels. Since there is a great dependence between them, each influencing the other and vice versa, the player’s position has a direct impact on blood movement based on their position. When standing, gravity pulls the blood downward, generating an accumulation of blood that requires movement to stimulate muscles and push the blood back up. When sitting, doctors observe pressure on blood vessels, especially in the lumbar region, interpreted as resistance against gravity, causing nerve tension and slowing blood circulation, with an accumulation of blood in the legs, leading to the pain felt by gamers over time. When lying down, although this does not affect circulation, there is a risk of blood stagnation, which is why hospital beds are designed to reduce this stagnation.

Zero Gravity Chair Technology

Following this summary, we see that these chairs offer an ideal position to reduce blood accumulation in the legs, thus avoiding the sitting position and its harmful effects on blood circulation. Some chairs are even designed so that the legs are elevated to the heart level to ensure good blood circulation, taking into account the assumption that players want to sit for a long time.

Zero Gravity Chair: A Multitude of Creations and Innovations

What I like a lot about this chair is that, with its design, many features can be added or developed, whether in terms of relaxation and ergonomics, entertainment, or design. For example, there are chairs offering an almost total body massage option, vibrations synchronized with the game like PlayStation controllers, LED strips for a modern or minimalist style, a fast phone charging option, etc. In general, all the options found in high-end cars can be added to this chair because they share commonalities.
