Spinal-glide™
Ergokinetic™ Chairs
// Welcome
Spinal-glide is the first patented ergokinetic seat designed specifically to enhance the movement of the pelvis and lower back. Our jobs require hours of sitting in chairs without any mechanism to adequately allow the body to move.
When we walk, we are in a weight-bearing position and the pelvis moves through a specific range of motion. When we sit we are also in a weight-bearing posture yet we sit in seats that don't allow the pelvis to move through any range of motion.
Even when we are seated and reach forward with the right arm, the left side of the body moves back. If the seat doesn't move, this reciprocating motion of the body is impeded. Spinal-glide achieves this by using a spring split-seat that allows the pelvic bones and back to move as if we are still walking.
The seats are separated by a narrow space that allows the coccyx (tailbone) to hang rather than touch the seat pad eliminating compression of the sacrum and lumbar spine in the lower back. All seats are comfortable for the first few minutes, but unless there is a massager in the chair, after a few minutes wstart to fidgit, our body needs to move.
If we are required to sit for such long hours then we need seats that enhance the normal range of motion of the pelvis and lower back. Spinal-glide is specifically designed to allow the body to move and enhance the motion of the pelvis and lower back.
Anatomical Explanation
The Spinal-Glide split seat chair is an ergokinetically designed seat that reflects the range of motion of the skeletal structures of the body. The human body is in constant motion from reciprocating sway from one side to the other as well as anterior-posterior flexion-extension, and an external-internal cycle of the skeletal structures that allow fluids and soft tissues to flow throughout the body. Movement is essential for the body, even when in a stationary position.
Osteopathic anatomical research describes an inherent range of motion of the skeletal system that exists for the purpose of allowing the flow of cerebral spinal fluid around the brain, through the spinal column and into the sacral reservoir in the pelvis. This inherent motion is referred to as the primary respiratory mechanism and is an intrinsic rhythm of the skeletal structures to enhance the absorption, flow and drainage of cerebral spinal fluid.
The cerebral spinal fluid acts as a nutritional delivery mechanism for the spinal nerves, a drainage system for metabolites, and a lymphatic system all encased inside a series of sheaths that separate it from the blood system.
The plates of the skull, the spinal column and the three pelvic bones move through a subtle flexion-external and an extension-internal range of motion centered around the spheno-basilar junction in the cranial vault. The flow of cerebral spinal fluid is essential for the health and integrity of the brain and spinal cord.
In order for the cerebral spinal fluid to flow throughout the skull and spinal column, there must be adequate movement of the skeletal system to allow the expansion and contraction of the cranial structures ensuring absorption and draining of the cerebral spinal fluid. Whether one is still or moving, the cerebral spinal fluid still persists at a fifteen second pumping cycle, however too often we are forced to sit for long hours in seats that do not allow mobility.
The coccyx bone is the most inferior part of the sacrum, which becomes weight bearing in a seated position not allowing vital flow of the cerebral spinal fluid. The sacrum should be suspended between the two pelvic bones as it is a non-weight bearing joint. If the sacrum and coccyx are held stationary, there is a reduction of the reciprocating motion between the bones of the skull and the bones of the pelvis.
After a few minutes of sitting in a single seat chair, the body and the pelvis need to move. We start to fidget in the seat. We feel as if we must get up and move. Walking accentuates the motion of the pelvis and restores the flow of cerebral spinal fluid from the sacral reservoir. Unfortunately, too many of us sit for long hours at work and are too engaged or too busy to get up and move around.
The Spinal-glide ergokinetic split-seat allows the pelvis and sacrum to pitch, roll and yaw reciprocally without restriction. This seat is extremely comfortable, the springs are scientifically placed to allow the most effective motion of the pelvis and lower back, and the seat cushions are made of a patented mixture of supportive ergonomic material, which works in harmony with the spring seats, allowing movement, and providing support, which encourage productivity.
Introduction;
Spinalglide is the first ergokinetic chair. Ergokinetic is work in motion. When you study the human form in ergonomics, it is important to consider the skeletal structures when someone is seated or standing at work. However, it is equally essential to consider and study the body in motion and attempt to emulate that movement when one is seated at a workstation. The body requires mobility and its skeletal structures should not be impeded. The spinalglide does just that, allows the pelvis and lower back to glide through a normal range of motion.
Function;
Spinalglide achieves mobility by using two separate spring supported spit-seats that allows the pelvic bones and lower back to move as if you are still walking. The seats halves are separated by a narrow space that allows the tailbone to hang rather then touch the seat pan, which eliminates compression of the sacrum and lower spine.
Spianlglide allows the sacrum and two pelvic bones to pitch, roll and yaw to enhance the flow of essential cerebro-spinal fluid being pumped up and down the spinal column.

The evolution of ergonomics
Ergokinetics™, derived from the term ergokinesis, is the study of work in motion. Unlike, ergonomics which pertains to static position, structural support, proper positioning, ergokinetics is concerned with the movement of the body structure while sitting or standing in a work station.
The body, our physical structure moves. There are numerous rhythms in our bodies; heart rate, peristalsis, respiration, lymphatic fluid pumping and the flow of cerebrospinal fluid. Movement is essential to the body, especially the movement of the cerebrospinal fluid because it is directly dependent on the unimpeded flexibility of the skeletal system.
Ergokinetics™ does not replace ergonomic theory yet enhances the ability of an individual to work in a seated or standing stationary position for long periods of time without the body being forced in a fixed position. Ergokinetic™ products allow the person to move or be moved mechanically reducing the weight bearing pressures on the skeletal system.
Products considered “ Ergokinetic™” must enhance or allow movement to the bodies structural system. Sitting in a static chair only inhibits movement in the pelvis and lower back. We just split the seat to allow the pelvis to move reciprocally so as to enhance the two pelvic bones to go through a normal range of motion even when sitting.
