Please NOTE: We can make almost any size and welcome special orders - the options listed here are simply standard sizes.


  • The Trochanter Wedge is a convex-based wedge that helps to stabilize the lower extremities and redistribute pressure while inhibiting heat build up.
  • The Greater Trochanters are "cut-outs " to relieve pressure
  • The medial thigh separator and leg contours will assist in the alignment and slight abduction of the lower extremities.
  • The coccyx scooop and ischial step will inhibit sliding and provide a slight posterior pelvic tilt at the hips.
Additionally - The Trochanter Elite cushion is constructed with G.I.V.E. Plus foam which does not gas out like ordinary gel infused memory foam. G.I.V.E. Plus
  • Absorbs vibration better than memory foam
  • Has slide and reduces shear by moving under weight
  • Is effective in prevention of decubitus ulcers because of the slide and open cell properties of the material
  • Does not become overly firm in cold temperatures
  • Does not become overly soft in hot temperatures

Measuring Instructions for Custom Cushions

The three most basic cushion measurements are thikness, width & depth.

If the cushion you want to order is a wedge then the A measurement will be two numbers - a thickness at the front and a thickness at the back.

JDM uses a code system to specify our products

but it isn't necesary to place an order. The basic premise is that If the first number of a cushion code is a 1, then the product is a WEDGE CUSHION, and the next 2 numbers are the thickness at the front and then back. If the first number of a cushion code is 0, then it's a CUSHION (without a wedge shape/incline), and the next number is the total cushion thickness.
Once you've determined whether the cushion is a wedge or not and have the thickness the next two numbers are the Width, then the following two are the Depth. After that are features separated by dashes.

The following are examples of how JDM codes its products:

Example 1: Item # 031816-AH-AS-V
Profile Thickness Width x Depth Feature Code(s)
not a wedge
3" Thick
18" Wide x 16" Deep

In this example your patient needs a flat cushion that is 3-inches thick. The wheelchair measures 18” wide by 16” deep. You would like the cushion to be Anti-Hammocking with a layer of Visco on top, and an Anti-Skid Bottom. The order of JDM’s coding system is as follows:

Example 2: Item # 1432018-AS-DC-NSFB-V
Profile Thickness Width x Depth Feature Code(s)
4" Front to 3" Back
20" Wide x 18" Deep

In this example your patient needs a wedge cushion for a scooter. The scooter seat measures 20” wide by 18” deep. The patient is also prone to incontinence. The measurements indicate the thickness at the front should be 4" sloping down to 3" at the back and there needs to be a layer of Visco over the entire cushion for extra comfort and pressure relief. Since the scooter does not have a sling you would not want an Anti-Hammocking base so we would go with the NSFB code which simply stands for "No Solid, Flat Bottom". Since incontencne is an issue we would want a Double Cover (DC) which provides a second cover made from a special fabric and finished with waterproof zippers. Anti-Skid (AS) is a common feature to most of our cushions; it is a non-slip material which covers the bottom and attempts to ensures the cushion stays in place even when placed on smoother surfaces such as vinyl wheelchair slings.

Step 1: BASE
The following features relate to the bottom of the cushion and generally whatever style you pick precludes any other. Choose one style.
  • The ANTI-HAMMOCKINS (AH) base has a convex bottom that eliminates the sling effect of soft sling wheelchair seats.

  • The DEEP-CONTOUR base is only available by special request to remedy seat slings that have pronounced sagging.

  • DROP-SEAT CUSHION (D) cushions are ONLY for JDM Drop seats. They have hook fastener sewn to the bottom so they can attach to the loop fastener on our rigid drop-seat bottom.

  • DROP-SEAT a drop seat is a solid peice of composite material with hooks which replaces a wheelchair sling and lowers the seating height

  • The NO SOLID / FLAT BOTTOM (NSFB) does not have a convex bottom nor does it have a wood or composite bottom - it is intended for when a cushion will be used on a hard flat surface.

  • SOLID INSERT cushions have a solid piece of wood covering the bottom of the cushion.

These are features related to the side-view/profile of the cushion. SOME of these can be combined (an Ischial step is already a wedge and you can combine WF with any wedge or flat cushion but obviously a flat cushion cannot be a wedge)
  • A FLAT cushion (codes starting with 0 is the same thickness front and back. There may be features on top so that it is not truly "flat" but it simply means "not a wedge"

  • A WEDGE cushion (codes starting with 1) is thicker in the back than in the front. This feature inhibits forward leaning and sacral sitting.

  • The ISCHIAL STEP (I) is a type of wedge that looks like a "stair step". This feature gives an extra anchored support to the posterior tilt and can help prevent thrusting.

  • WATERFALL FRONT (WF) cushions have their front edge rounded. This feature provides comfort under the legs.

Most of the following features CAN BE COMBINED and most will work with any base and profile
  • The AMPUTEE LEFT (AML) denotes a left side accomodation for left LE residual limb

  • The AMPUTEE RIGHT (AMR) denotes a left side accomodation for right LE residual limb

  • The COCCYX SCOOP (CS) looks like a "saddle cushion". The contoured leg channels provide a slight abduction and improved alignment of the lower extremities

  • The CUTOUT (CV) is a cutout, usually in the back of a cushion to float the coccyx area to accomodate a wound

  • The DOUBLE COVER (DC) gives extra protection from incontinence.

  • A MEDIAL THIGH SEPERATOR (M) looks like a mound in the middle of the front of a cushion. This feature provides abduction for the lower extremities

  • WING LEFT (WL) cushions have a wall on the left.

  • WING RIGHT (WR) cushions have a wall on the right.

  • WINGS BOTH (WB) cushions have thick walls on both sides. Wings provide support and can bolster the thigh and hip aqnd keep lower extremeties in midline.

These features can be critical to accomodating greater weight or to provide necessary pressure relief and they will work combined with any combination of base, profile and feature.
  • The VISCO (V) gives extra pressure relief and comfort.

  • The DOUBLE VISCO (V2) gives even more pressure relief and comfort.

  • The FIRM BASE is available by special need and is a layer of firmer foam placed somewhere in the cushion layering.

  • The G.I.V.E. ELITE (GE) gives the most pressure relief and comfort.
