Skil-Care Tri-Foam Sling Seat Cushion 3 Sizes
Skil-Care Tri-Foam Gel-Infused Sling Seat Cushion — LSII Cover, Three Sizes
Built to Un-Hammock the Sling Seat
Every standard wheelchair sling seat has the same quiet problem: the upholstery hangs between the rails in a hammock curve, and the person settles into the sag. The Skil-Care Tri-Foam Sling Seat Cushion is shaped specifically to fix that — its contoured Tri-Foam base compensates for the curve to create a more level, stable sitting surface, improving positioning right where a flat cushion can't.
On top, a gel-infused viscoelastic foam layer conforms to the person while providing a cooler feel than standard foam through long seated stretches, and the LSII low-shear cover wraps the cushion in a smooth, durable, moisture-resistant surface that wipes clean easily. The practical 3" profile adds support without raising the seat so much that transfers get harder — available in three standard wheelchair sizes.

Key Features
- Sling-Sag Reduction: The contoured base is designed to reduce sling-seat hammocking for a more level sitting surface and improved positioning.
- Gel-Infused Visco Foam: A conforming top layer with a cooler sitting feel than standard foam.
- Tri-Foam Contoured Base: Three-foam construction for stable, supportive everyday seating.
- LSII Low-Shear Cover: Smooth, durable, moisture-resistant, and easy to wipe clean.
- Practical 3" Profile: Supportive height that stays transfer-friendly.
Equipment Specialist Insight: This is the cushion to reach for when the chair itself is the problem — if the person leans into the middle of the seat, slides toward center, or sits pelvis-tilted because the sling sags, a flat cushion just follows the curve, while this contoured base actually corrects it. The 3" profile is a deliberate compromise worth appreciating: enough foam to support and level, low enough that side transfers and standing pivots stay manageable. Measure the seat pan and match exactly — 18" x 16" fits most standard adult chairs. For solid seat pans or seats wider than 18", the Tri-Foam line's other configurations cover those chairs. Wipe the LSII cover during routine cleaning, inspect for flattening, and replace the cushion when the foam stops recovering.

Q: What is "hammocking" and why does it matter?
A: A sling seat is flexible upholstery stretched between the chair's side rails, so it naturally sags into a curve under weight. That curve tilts the hips inward and encourages slumping over a long day. This cushion's contoured base fills and levels that curve, giving the person a flatter, more stable foundation — which is the starting point for better seated positioning.
Q: How is this different from the standard gel-foam cushion?
A: Both pair gel comfort with a foam base, but this Tri-Foam version adds the contoured, sling-compensating base, a gel-infused visco top layer, and the LSII low-shear cover — a step up in both positioning and surface glide. The standard gel-foam cushion is the simpler flat design for chairs where sag isn't the concern.
Q: How do I care for the cushion?
A: Wipe the LSII cover with a damp cloth and mild cleanser and let it dry — it's built to resist moisture through everyday cleaning. Don't submerge the cushion. Check it regularly for flattening or damage and replace it when the foam no longer springs back.
Specifications are provided by the manufacturer and are subject to change; verify size and materials against the physical packaging, and confirm weight capacity with the manufacturer's specification sheet before purchase. Confirm the cushion size matches your chair's sling seat before use; the cushion raises effective seat height by its profile. A seating cushion supports comfort and positioning and is not a treatment for any medical condition; individuals with specific seating or skin-care needs should have cushion selection guided by their clinician or therapist.
