OBSS Ortho-Shape (fig. 3 & 4): A Plastizote foam liner (fig. 4A) is molded to create an intimate
fit with the end-user. The intimate fit creates optimal surface area and improved pressure redis-
tribution. One or more liners are provided with the product to customer specification. The inner
liner can be removed (fig. 4) to compensate for those occasions when the user wears thicker
clothes, if they have gained weight or otherwise grown in size. The custom shape (example:
lateral thigh support (fig.3A)) created by the fitting professional during the molding process
ensures additional functional support as necessary for the user. An ABS shell (fig. 3B) adds
additional structural support to the foam and creates a mounting surface for the connection of
additional positioning products and also attachment to a mobility base. A textile cover is the
direct interface to the user creates a slight cushioning effect and comfortable upholstered sur-
face for the user. The ABS shell and Plastizote liners can be reshaped in the field by a qualified
technician (following the instructions in this manual) to accommodate changing positioning
needs.
For all products additional positioning accessories may be included with the product or
ordered separately to the trained professional’s specifications. Typical selections include a
head support, positioning belt
and torso positioning device/harness.
