The word is pronounced /njuːˈmætɪk ˈkʊʃən/ with emphasis on the first syllable. "Pneumatic" is spelled with a silent "p" and pronounced as "new-ma-tik". "Cushion" is spelled as it is pronounced, with emphasis on the second syllable. Together, these words refer to an inflatable cushion that is filled with air or gas to provide support and comfort.
A pneumatic cushion is a soft, flexible, inflatable device designed to provide comfort and support to the body or other objects. It typically consists of a sealed, airtight chamber that can be filled with air or another gas, allowing for adjustable levels of cushioning and firmness.
Pneumatic cushions are commonly used in various applications to enhance sitting or resting experiences. In the medical field, they are utilized in the form of pressure-relieving cushions to prevent or alleviate pressure sores and ulcers in patients who are confined to a bed or wheelchair for extended periods. The adjustable air pressure in these cushions enables weight distribution and reduces the risk of pressure points and skin breakdown.
Furthermore, pneumatic cushions are often employed in industrial settings to provide ergonomic seating for workers who endure long hours of sitting. These cushions offer dynamic support by contouring to the individual's body shape, reducing strain on the back, hips, and legs. They can also be found in automotive seats, office chairs, and even in sports equipment such as bike saddles or stadium seats, enhancing comfort and reducing the impact of vibrations or shocks.
Overall, pneumatic cushions contribute to an improved sitting or resting experience by combining flexibility, adjustability, and support. Their inflatable nature allows for easy transportation and storage, making them a practical and versatile solution in a variety of settings.
The word "pneumatic" originates from the Greek word "pneuma", meaning "wind" or "breath". It entered the English language in the 17th century and referred to anything related to or operated by air or gas pressure.
The word "cushion" has its roots in the Old French word "coissin" and the Latin word "coxa", both meaning "hip" or "thigh". It later evolved to refer to a soft padding or support used for comfort.
Therefore, the term "pneumatic cushion" combines the idea of air or gas pressure (pneumatic) with a soft support (cushion). It describes a cushion or pillow that is filled with air or gas to provide comfort and support.
