The Varilite Meridian wheelchair cushion features a dual chamber to form an integral pre-ischial ridge and wedge effect for enhanced comfort, support, and pressure redistribution.
The Varilite Meridian weighs less than 1kg, requires no kneading, pumping, or manipulation, and delivers skin protection and postural support. Combine with a Varilite Wave base (see Evolution & Meridian Wave for details) for more lateral and medial support.
The cushion is available with a mesh or water-resistant cover with breathable two-way strech material. The reticulated foam inside the cover promotes air exchange and improves pressure redistribution.
1. Air-Foam Floatation
The functional areas of the cushion are created by three types of foam; soft foam under the pressure risk area of the ITs; medium foam for the thigh trough, pelvic bucketing and pre-ischial ridge; and firm foam to provide lateral support and a medial thigh separator.
2. Dual Chambers
The dual-chamber design of the Meridian allows for independent positioning of the thighs and pelvis. Adjustments are quick and easy, and can be performed with the client seated. The front and back air chambers of the Meridian limit sacral sitting and promote good posture. The pre-ischial shelf created by the dual-chambers stops the Its from sliding forward, thus limiting a posterior pelvic tilt and sacral sitting. The squeeze created by the separate air chambers provides postural support by ‘holding’ the client in place.
3. Valves for Adjusting Air Volume
Easy to use, two-way air valves allow simple and efficient adjustment. Once the client is seated on the fully inflated cushion, the right valve can be released allowing air to escape from the pelvic chamber. Once proper immersion of the pelvis has been achieved the user releases air from the front/thigh chamber by opening the left valve. Once optimum load on the thighs has been achieved the valve is closed.
The Meridian is available with a mesh or water restrant cover with breathable two-way stretch material. Reticulated foam inside promotes air exchange and improves pressure distribution. The underside is a rugged nonslip material with hook and loop for added security. The Meridian cover meets ISO 7176-16 ignition standards for upholstered wheelchair components and is machine washable.
