The Solid Insert Ischial Step utilizes the natural curvature of the body to give an anchored support, and uses the posterior tilt of a wedge to prevent sliding. This combination moves the weight bearing pressure to the I.T.’s.

Because this pressure is being placed onto the solid-insert bottom, all solid-bottom Ischial Steps will have a minimum of 2 inches of HR Polyurethane foam, as well as 1 inch of Visco at the rear of the cushion to accommodate this I.T. pressure. Due to Visco’s compression capabilities, the additional one inch of Visco adds very little height when sat upon.

Considerations when utilizing a Solid-Insert Cushion or Wedge:

  1. The Solid-Insert in these cushions eliminate the hammocking effect of a sling-bottom wheelchair by elevating the individual above the upholstery tubing.
  2. All of JDM’s Solid Inserts must have a minimum of three inches of our High Resiliency (HR) Polyurethane as a cushioning damper between the insert and the patient, or the cushions/wedge may have a combination of at least two inches of HR along with an additional inch of Gel-Infused Visco Elastic (G.I.V.E.) for pressure redistribution. In other words, all standard solid inserts must be a minimum of three-inches thick. Please note: due to G.I.V.E.’s compression capabilities, the additional one inch added to the cushion or wedges’s height is minimized. Example: 3” x 18” 16” with Visco (031816-AS-V) will sit like a 2” thick cushion with a solid insert.
  3. All of JDM’s Solid-Insert Cushions have Velcro strapping to attach under the vinyl seat to prevent the cushion from twisting and sliding.
  4. All of JDM’s Solid-Insert Cushions have a rubberized anti-skid bottom to further prevent the cushion from sliding, as well as to prevent the wheelchair’s upholstery tubing from rubbing into the fabric.
  5. By utilizing JDM’s feature code system, the cushion or wedge may be modified to accommodate many of the problems found in long-term care.
