EquaGel® dry-polymer gel is almost rubbery to the touch. It has unbelievable tensile and compression strength and incredible durability; but these are not what make EquaGel® special. Its most amazing feature is the column buckling.
Simply put, column buckling refers to the way EquaGel® behaves under weight. Each wall of gel is capable of supporting only a light load. When that threshold is exceeded, the wall of gel buckles into the hollow area between walls and passes the weight to the surrounding walls for support. This “buckling and weight-passing” happens instantly and repeatedly until the maximum surface area of pressing weight is evenly supported by largely equalized pressure (hence our name, EquaPressure®). Buckling Gel has been demonstrated to minimize pressure better than other technologies.
The peak pressure points of the ischial tuberosities and the coccyx/sacrum buckle into the EquaGel® feeling almost as if they are free-floating within the cushion while the thighs and buttock of the user are supported.
2 LAYER GEL Our EquaGel® cushions feature a bi-columnar design of integrated gel. This means our gel cushions have a smaller top grid of gel incorporated with a larger bottom grid of gel. These layers cannot separate.
The top layer of EquaGel® is made of a small grid with thin walled gel. These walls of gel are not primarily weight-supporting walls but rather are pressure redistribution walls. They are very soft to the touch and quickly act to distribute the user’s weight across the surface of the cushion and away from pressure points.
The bottom layer of EquaGel® is made of a larger grid with thick walled gel. These walls are more robust and designed to continue the weight redistribution from above as needed and support the user in good alignment. They are also sufficiently strong (without becoming hard or resistant) to hold users from bottoming-out the cushion under normal usage.
