The Lumex Basic Wedge Cushion is specifically engineered to improve seating stability and prevent the user from sliding forward in their wheelchair. The unique wedge design provides a gradual slope from 4 inches in the front to 3.25 inches in the rear, which encourages a natural upright posture. Inside, a specialized gel bladder is sandwiched between a high-density foam base and a convoluted foam topper to ensure maximum immersion and pressure relief at critical points. This response includes details for 7 variants.
