Stimulite honeycomb relieves pressure by distributing it away from hot spots. As a result, bony protuberances "feel" the same pressure as the surrounding anatomy. The honeycomb cells conform to body shape, and distribute weight over a much wider area than conventional products comprised of foam, gel and air. Additionally, Stimulite honeycomb stabilizes any position due to the axial buttressing of the honeycomb cell walls perpendicular to the anatomy. As an added health benefit, the honeycomb cells flex and compress with movement, stimulating blood flow to enhance circulation Shear Force Reduction The horizontal stiffness of a material determines both its shear resistance and stability. Too much stiffness increases shear forces, while too little decreases stability. Stimulite honeycomb minimizes shearing without sacrificing stability. The honeycomb cells align themselves axially to the body, flex with movement to reduce shear forces against the skin and then instantaneously resume their original shape Skin maceration is softening of the skin as a result of continual exposure to heat and bodily fluids or moisture. Severely softened or macerated skin is less tolerant of pressure and can lead to breakdown. Stimulite honeycomb is perforated, enabling air to circulate and moisture to evaporate which helps maintain skin integrity and keep the body at ambient temperature. All of our Stimulite products are machine washable and dryer safe, making it easy to maintain good skin hygiene.
