Stealth Custom Seat Cushion Overview
The redesigned and re-imagined custom seating brings the best of Stealth with more streamlined design, better materials and simplistic ordering process.
We have re-evaluated the complex rehab process to be able to offer this new line of custom seat cushions that we hope will cover all the basics, plus other challenges along the way. The Custom Seat Cushion is an adaptable seat cushion.

The cushion's cover consist mostly of three materials. The contact (top side), non-contact (sides) and anti-slip (bottom side). The non-contact materials (sides and bottom) are always the same, but for the contact material we offer three variations: Coolcore®, Stealth-Tek and Air Mesh.
Stealth custom seat cushion allows for up to 3 configurable layers, the upper (top), the middle, and the lower (bottom) layer. The cushion requires a 5/8in (15.88mm) closed cell foam base which you have to consider when configuring the cushion. If additional layers are required, contact our CSR's or your local representative.
The custom seat cushion starting point would have anti‑thrust (AT), but this can be omitted if the AT is not required. The cushion will allow contour configurations that are adaptable to the client's needs.

Coolcore is a research proven performance fabric technology that adapts to its environment and regulates temperature by managing heat and moisture. The proprietary construction helps manage and distribute moisture quickly throughout the fabric to enhance the evaporation and drying time. More Details.
Stealth-Tek is a cast coated fabric, which is nylon/polyester fabric coated with polyurethane through the cast coating method. These type of fabrics are waterproof with stretch capability and applications in medical and healthcare. StealthâTek is Fluid Proof PU Film laminated to 100% polyester knit T-jersey. It is used in a variety of applications. Waterproof, Breathable and Washable.
Air Flow Mesh, better known as Air Mesh, is equipped with fine pores for superior air circulation, it can assist with positioning if the client has sliding issues with the current cushion cover material. This fabric is ideal for those in hot or humid environments.
The Polyurethane Liner provides four (4) way stretch, waterproof barrier between the cushion cover and the cushion foam and comes with a waterproof zipper.
The Custom Seat Cushion is available with an optional zippered pouch. This option adds a small pouch to the front of the cushion. 8in (20.32cm) Width x 5in (12.70cm) Height
Custom Seat Cushion Foam Options
The initial structure for the seat cushion foam consist of the base layer and the lower layer. Each foam layer can have a thickness for up to 2in (5.08cm) at 1/2in (12.70mm) increments. If additional thickness or layers are required just contact one of our representatives.
The upper layer is reserved or mostly used with soft material since is the layer in direct contact with the client. At a range of 1/2in (12.70mm) thickness, the upper layer wraps towards the front of the cushion to maintain a constant comfort for the client. This means if the upper level is 1in (2.54cm) thick, two layer 1/2in (12.70mm) thick will be glued together, wrapping the top one towards the front of the cushion.
The middle layer can also include softer foams as well as medium resistance foams. Layer thickness can go up to 2in (5.08cm) thickness at 1/2in (12.70mm) increments. If a thicker layer is needed contact one of our representatives.
The bottom layer recommended foam materials are medium to firm. This will prevent the client from feeling any contour configuration foam materials which are normally more thick to provide abduction and adduction support.
Use to place abduction and adduction structure material consisting of Etha foam. Placed under the main layers to avoid discommfort to the client and above the anti-thrust and base to help maintain contoured shape.
The anti‑thrust provides a boundary to minimize forward migration of the ITs into a posterior pelvic tilt. Consisting of a closed cell foam, the anti‑thrust is a pre‑ischial support surface intended to inhibit forward migration of the ischial tuberosities.
Often used when extensor tone is present. The initial placement is half the depth of the cushion to allow for 1in (2.54cm) to 1 1/2in (3.81cm) from ITs to the front edge of anti‑thrust.
Required base 5/8in (15.88mm) foam, consisting of a closed cell firm foam for rigidity and easy handling.
Open cell polyurethane foam is a soft foam. Open cell refers to the cell walls, or surfaces of the bubbles, which are broken so that air fills all of the spaces in the material. Closed Cell foam is a rigid material that provides the kind of stability required for the base of many of our pads and cushions. Use mostly for base and other structural functionalities. Ethafoam® is a polyethylene foam plank that is flexible and durable. Waterlight weight impervous to most chemicals. Used for the contour layer to accomplish abduction and/or adduction.
SunMate® FRG cushions provide the same high impact energy absorption and soft pressure properties as regular SunMate®, but with an added element of safety. SunMate® FRG contains a non-halogenated fire retardant that allows the cushion to pass more stringent fire tests. FRG also provides medical or government facilities, required to purchase equipment that meets strict fire codes, with a safe, high-quality cushion option.1
The FRG is a patented all‑natural fire retardant material (no additives) made of 33% to 36% plant‑based ingredients.
Custom Seat Cushion Format
Stealth's custom seat cushions allows you to create a personalized experience. With a range of options from anti‑thrust, abduction, adduction or none at all.
The contouring for the seat cushion is handled under the main layers and right above the base foam to avoid any discomfort but maintaining, at the same time, a solid and static configuration.
The Anti‑Thrust (AT) is the initial state for the custom seat cushion. It's function is to keep the client from sliding out of their mobility base and preventing pressure discomfort as well. The closed cell foam AT barrier prevents forward and sacral sitting while maintaining pelvis neutral position.
The height of the Stealth Custom Seat Cushion AT is measured from the surface of the cushion at 1/2in (12.70mm) increments ranging from 1/2in (12.70mm) to 2 1/2in (6.35cm).
The Planar format is the omition of the AT initial cushion state. The planar seat cushion consist of the closed-cell 5/8in (15.88mm) foam base and a single layer of foam.
The illustration above shows the cushion with three layers, the two upper layers are optionals. For layer options check foam options section.
The function of the abduction on a cushion is designed to help properly position knees of the client while seated. The depth of the abductor can be set on 1in (2.54cm) increments, while the height is calculated from top surface from 1/2in (12.70mm) to 2 1/2in (6.35cm) at 1/2in (12.70mm) increments.
If a more specialized abduction is required, ask one of our representatives about our abductor pads and harware. For individuals with spinal cord injury or severe physical or neurological abduction disabilities contact a certified therapist or physician for a professional diagnosis and recommendation.
The function of the adduction is to help poistion the client legs towards a midline plane and help maintaining, at the same time, a proper pelvis posture. The depth of the adductor is always the same depth of cushion, while the height is calculated from top surface from 1/2in (12.70mm) to 2 1/2in (6.35cm) at 1/2in (12.70mm) increments.
If a more specialized adduction is required, ask one of our representatives about our pelvic and knee support solutions.
Abduction and adduction can be combined for a full contour comfort. This combination can help with proper pelvis positioning as well as maintaining a more proper posture foundation.
Full contour will required abduction and adduction specifications, and if presented, anti‑thrust (AT) depth and height.
The AT and abduction depth are set at 1in (2.54cm) increments, while adduction depth is always equal to cushion's depth. Both abbduction and adduction heights can be set independently at 1/2in (12.70mm) increments from 1/2in (12.70mm) to 2 1/2in (6.35cm) height.
The AT height is measured from the surface of the cushion at 1/2in (12.70mm) increments ranging from 1/2in (12.70mm) to 2 1/2in (6.35cm).
Custom Seat Cushion Special Configurations
The custom seat cushion can be modified with special cut-outs and relief implementations. From growth notches for depth growth, to Ischial relief modification, with these modifications the custom seat cushion extends the posibilities of comfort and growth adaptation.
Available Configurations:

LLD Configuration allows to adjust the seat depth independently per side. The width is predetermined to be half width of the cushion and can be set from 1/2in (12.70mm) to 2in (5.08cm) at 1/2in (12.70mm) increments. You can also use this configurations to accomodate a residual limb support hardware.
The I‑Style allows for growth width adaptability of the lateral pelvic support. The cut-out comes in a predefined dimension of 3in (7.62cm) depth and 2 1/2in (6.35cm) wide per side.
Growth notches are cut outs that allow you to ajust client growth back and fro for the seat depth. The width of the notch is 2in (5.08cm) and can be set to three different depths from 1in (2.54cm) to 3in (7.62cm) at 1in (2.54cm) increments.
A hamstring relief is an approximately 45° angle cut to the front of the seat cushion that helps prevent forward migration of the pelvis due to shortened or tight hamstrings. Also aids in prevention of contact with the back of the legs.
The ischial relief helps to prevent or address coccyx pain by using gel inserts to distribute the pressure in a more organic approach. There are two gel options to choose from which address different types of clients, a) Viscous Gel and b) Ultra-Lite.
Mounting Options
The custom cushion is tested to support up to 350lbs (158.76kg) with the following mounting options, Stealth proprietary Seat Pan and also the same rigidizer pan we use with our after market line of cushions, the ACM Rigidizer Pan.
We also offer other options as the ADI Seat Pan for a more lighter option but has been tested for up to 200lbs (90.72kg). Also ask for our Flat Rigidizer, if the following tested options does not fit your needs. You need solutions, we have them, Solutions for Life™:
The aluminum seat pan has been tested to match custom cushion weight maximum support of 350lbs (158.76kg). The seat pan is black anodized powder coated.
Also this seat pan will match cushion dimensions except if any special configuration is requested such as the Hamstring Relief, in this case the seat pan could be either 1in (2.54cm) or 2in (5.08cm) shorter than the seat total depth.
Depending on cushion dimensions there could be limitations of how many configurations can be combined, taking into consideration hardware placement requirements and weight capacity.

Coolcore Technology
While the other makers of cooling fabrics use a number of chemicals to enhance wicking, transportation and evaporation, Coolcore fabrics are chemical free. To make that possible, we changed the essence of cooling fabric technology right down to its very core.
from Coolcore Website
A great base layer in summer is a great base layer in winter.
Stealth's Cushions Thermoregulation line is not a new technology, but a new application. The Coolcore Technology starts with cooling but the patented yarn technology makes for a better textile that provides year‑round temperature regulation.
Coolcore is a research proven performance fabric technology that adapts to its environment and regulates temperature by managing heat and moisture. The proprietary construction helps manage and distribute moisture quickly throughout the fabric to enhance the evaporation and drying time.
Normally other brand fabrics use topical chemicals that not only can be harmful to your skin, but after only a few washes, the cooling properties of the product are no longer effective. The Coolcore cooling technology is built into the fabric fibers, preventing any decline in the performance and keeping it's cooling properties. Coolcore patented technology allows for a controlled evaporative process that keeps you cool, dry and comfortable in any condition.
Research driven, patented fabrics from Coolcore are chemical-free and yield remarkable benefits. They cool better, last much longer and offer protection from the suns harmful rays (UPF)
