Varilite Meridian Cushion is air and foam floatation, coupled with multi-stiffness foam. Meridian is an adjustable Air-Foam Floatation skin protection cushion. Bonding of the meridian foam to coated fabric makes the cushion hold air. The four-way-stretch knit fabric allows for maximum conformity during immersion and the fabric is puncture & water resistant.
Air and Foam floatation
Three types of foam are used to make it functional: soft foam is used for the decubitus-sensitive area of the ITs; medium foam is used for the thigh trough, pelvic bucketing and pre-ischial bar; firm foam is used for the perimeter and the medial thigh separator.
Front and rear chambers permit independent adjustment of the pelvis and thighs, quickly and easily, while the client is seated. Front chamber allows maximum loading of the thighs which reduces pressure on the ITs and the rear chamber allows maximum immersion of the pelvis for better pressure distribution.
Dual-chamber design helps in promoting a neutral pelvis position for clients who are prone to extensor tone or thrusting. Thigh & pelvic chambers form a pre-ischial ridge which prevents the ITs from sliding forward, preventing a posterior pelvic tilt & sacral sitting.
Releasing more air from the pelvic chamber than the thigh chamber provides added postural support by creating dump or squeeze that “holds” the user in place.
It improves stability for users with compromised sitting balance or who transfer frequently. Multi-stiffness foam provides support as the user is immersed in the cushion. Medial & lateral supports minimize internal & external lower extremity rotation.
Valve for adjusting volume
Meridian uses two-way air valves. Sitting on a fully inflated cushion, the user opens the right valve and releases air from the pelvic chamber. Optimal immersion is achieved when there is 1/2 inch of air & foam between the ITs and the wheelchair seating surface.
Immersing the pelvis while the thigh chamber is fully inflated creates a wedge effect that shifts the load from the ITs to the thighs. The user can decrease the amount of wedge achieved by opening the left valve to release air from the thigh chamber.
Meridian is available with a mesh or incontinence cover with breathable four-way-stretch material. Reticulated foam inside promotes air exchange & improves pressure distribution. The underside is a rugged nonslip mterial with hook and loop for added security. Both covers are machine washable.
