Does the zero gravity chair really offers zero gravity ?
The basic concept for the development of the zero gravity chair actually came from NASA and the experiences of its astronauts who spent long hours in space. During the process of take-off of the rockets, astronauts lie back with their feet higher than their hearts. This position of the body reduces the amount of force exerted on the spine by the extreme speed at which they travel in their space craft. Generally in an upright standing or sitting position, gravity exerts pressure on the spine causing the spinal discs to compress and spinal muscles to contract to maintain balance of the body. When the force of the gravity is neutralized, muscles rest and the spinal discs return to their normal size and shape.
The zero gravity chairs are manufactured by the Dutch Stokke and it promises to deliver comfortable sitting to the extreme level. The zero gravity chair allows you to sit in four positions, being suitable for a wide range of situations like from a comfortable working position to a reclined position and a feeling of almost weightless. The sloping seat of a zero gravity chair allows the user a wider space between the thigh and the upper part of the body, the leg cushions prevent sliding forward when working at a table. When leaning back legs of the user will be lifted higher than their head providing them with the best position for relaxation. When the user leans back in a zero gravity chair, it provides a whole new level of relaxing comfort. Doctors also recommended the unique position offered by a zero gravity chair to help relieve pressure and stress on the body parts.
Some of the zero gravity chairs available in the market feature an special guide rail system and a unique braking system to put the user smoothly into the right position of their choice without any inclusion of bulky hardware. These chairs are available in the market made out of various materials and styling some of the models has a hand carved base too. The choice of the upholstery also varies a great deal and is available in a variety of color combinations.
The zero gravity chairs are designed to relieve the pressures experienced in an upright position by the body. By extending the lower portion of the legs above the heart, the spine is allowed to decompress. This particular position offers many advantages to the user like it reduces the pressure on the spine that causes reduced muscle tension, less pressure on the heart and expanded lung capacity and increased circulation and increased blood oxygen levels.
There are many zero gravity chairs available in the market the styling includes from fully upholstered ones in traditional and contemporary designs at the same time chairs made for outdoor use. These chairs are designed in such a way that they follow the natural curves of the spine while providing full lumbar and upper back support to the body of the user. These zero gravity chairs move quite easily from full upright position to full recline position, making it easy to get in and out.
