Staff Writer Most gel seats work on a familiar principle that takes its cue from the studies of pressure. Because the human body tends to concentrate much of its weight on a few square inches while standing or sitting, these contact points are often touchstones for a variety of maladies. Discomfort in the form of chronic pain and tingling is only the beginning. Proper sitting posture is based on a number of things, including spinal alignment, proper head tilt, leg orientation and the comfortable support of a structural seat pan. Without these essential elements in place, you may experience what countless people contend with every day-aching back and leg numbness that can linger long after that five o'clock bell. Gels have become popular because they combine structural elements with an essentially shapeless fluid. When you shift, the shape of your seat compensates by migrating elsewhere in the pad. Even gels have their drawbacks, however, which is why some more innovative solutions have recently begun to gain a toehold in the ergonomic industry. The latest idea is a mixture of waterbed and air cushion technologies, and it has come through a number of rigorous tests with a sterling reputation. Because water cannot be compressed like a gel, it tends to be hardier when combined with gaseous elements like pressurized air. The best of these approaches have resulted in seat cushions that are robust, kinetic and surprisingly comfortable |
