It is not a liquid.
This gel has unbelievable tensile and compression strength. One of its most amazing features is referred to as column buckling. Simply put, each wall of gel is capable of supporting only a marginal load. When that threshold is exceeded, the wall buckles under 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 sufficient walls to hold the weight up, regardless of its shape.
Applied to seat cushions, the pressure points of the ischium and coccyx are allowed to buckle into the cushion without resistance while the buttocks are supported evenly.
The area’s most likely to develop pressure sores are allowed to float nearly pressure-free within the pad while the client’s weight is distributed evenly across the cushion.
