Precision-engineered to deliver critical performance advantages inside and out! On the outside, the individually articulating cells of the clinically proven Geo-Matt top surface combine with Span-America's proprietary Shear Transfer Zone design to provide unmatched protection from the harmful effects of microshear, macroshear and rotational shear. Helps reduce caregiver injury by the user back to position following head of bed elevation. On the inside, the 3-Dimensional Zoning core design of the UltraMax provides anatomically calibrated levels of support and unmatched user comfort. And in the seat area- where the mechanical fatigue of bed gatching and concentrated user weight affect durablity most- the unique cell structure of the high resiliency UHP 500 layer provides a 55% higher Support Factor than found in typical medical grade foams . Viscoelastic foam and gentle Heel Slope provide added protection at vulnerable heels. FeaturesUnique Geo-Matt surface The exclusive Geo-Matt style foam topper is a high density, medical grade foam. The unique geometric design consists of over 800 individual cells, each of which acts individually to redistribute pressure, to reduce heat and moisture buildup on the skin, and to reduce shear to underlying tissues. This foam topper is 2 in height and includes the Heel Slope feature, designed to further reduce pressure for the sensitive heel area.Shear transfer zones Shear transfer zones creates shear-minimizing bands beneath heels, sacrum and scapula and helps user to original position following gatching while providing overall stability and offsetting frictionTwo-way Heel Protection Segmented viscoelastic foam cradles the heel. Gentle Heel Slope redistributes pressure to more pressure-tolerant lower legs, providing enhanced skin integrity and comfort.3-Dimensional Zoning Core Design Provides anatomically- calibrated levels of support and immersion throughout the surface. Benefits include optimized tissue load management, enhanced product longevity and extreme comfort.UHP 500 Ultra High Performance Foam A 55% higher support factor than typical medical-grade foams andunmatched protection from bottoming out even with HOB elevated. This foam has superior resiliency and recovery, even when compared to typical HR foams.Firm Perimeter Provides Edge of Bed Stability Firmer edges provide safer transfers, more stable edge-of-bed sitting, and reduced risks of entrapment in siderail/mattress gaps.
