Product Description
AliMed® Sit-Straight™ Basic Wheelchair Cushion offers good support for those who do not need specialized care for pressure relief or shear reduction. Combines a Solid Seat Insert™ base with a wedge cushion to discourage harmful sacral sitting. The convex base design counteracts the negative effects of a sagging sling seat by filling the sag without modifying the wheelchair or raising the surface’s height. The wedge top limits forward sliding and maintains hips at 90° for optimal postural support. The end result is proper sitting posture, improved sitting tolerance, and functional independence. Removable, wipe-clean, water-resistant cover with nonskid bottom is fully launderable with rear ties for security. Available in Black Stretch or Ocean Blue Polyknit cover and two widths: 16" or 18".
3-3/4"H tapers to 3"H rear • Firm Polyfoam
