For individuals requiring moderate to high pressure customisable relief, the Protector is 2 ½” or 6.4 cm of patented EquaGel with a ¾” contoured pelvic bucket sculpted in for stability and comfort. The Adjustable includes two different pelvic contour inserts that can increase the amount of therapeutic gel under the pelvis from 1 ¾” to 2”, 2 ¼”, or 2 ½” deep. This can provide additional contoured support for the coccyx and reduce posterior pelvic tilt. Equagel is a dry polymer rubber-like material shaped in a column lattice. These columns buckle proportionally to the weight being applied to them, thus giving exceptional pressure distribution as it continuously adjusts to your every move. The columns promote airflow and maintain the surface cool in temperature. This cushion is extremely resilient and will never lose its shape or cushioning ability – it will not go flat or soften over time. It requires very little maintenance and can be machine-washed.
