Varilite Meridian Wheelchair Cushion
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.
Features of the Meridian:
- The Varilite Meridian Wheelchair Cushion 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 Meridian cushion is available with a mesh or water-resistant cover with breathable two-way stretch material. The reticulated foam inside the cover promotes air exchange and improves pressure redistribution.
Benefits of The Meridian:
1. Air-Foam Flotation
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 resistant (incontinence) 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.
Varilite offer a family of contoured bases for positioning support. Clinicians can combine the Meridian adjustable Air-Foam Flotation skin protection cushions with a solid ‘enhanced positioning’ base.
There are three different wave designs available:
• CPW (Contoured Positioning Wedge)
• LPB (Lateral Positioning Base)
• CPB (Contoured Positioning Base)
These bases enhance the Meridian’s natural positioning benefits in the sagittal (anterior – posterior) plane and provide further lateral and medial positioning support for both the pelvis and the legs, at the same time permitting greater envelopment of soft tissues, and thereby providing wider pressure redistribution away from the bony prominences, such as the ischial tuberosities (ITs). Increased gluteal off-loading of forces on the ITs is a further benefit.
