The VARILITE Rigidizer, or solid insert, counters the effects of sling upholstery. For many wheelchair users, sling seating promotes internal rotation of the lower extremities, sacral sitting, posterior pelvic tilt, loss of natural lumbar lordosis, and obliquity of the pelvis. Such poor positioning can result in discomfort and long-term problems.
A Rigidizer offers an easy and cost-effective solution to the problems of sling seating. Made from durable plywood, the Rigidizer can be placed between the cushion and upholstery, or, preferably, inside the cushion cover. With the Rigidizer in place, the user benefits from improved sitting balance, more neutral pelvic position, greater spinal extension, and overall improved comfort.
