Mind Reader Heated Memory Foam Seat Cushion with Gentle Therapeutic Heat This heated memory foam seat cushion is designed to provide targeted ergonomic support combined with gentle warming comfort for seated use at home, in the office, or while traveling. The slim Air-Cloud memory foam construction helps distribute weight evenly while reducing pressure on the tailbone and hips without significantly raising seat height. The built-in heating element offers four adjustable heat settings intended to deliver soothing warmth rather than intense heat. A timer with automatic shut-off allows for controlled use during seated sessions and adds an extra layer of safety. This cushion measures 18 inches long x 13.5 inches wide x 2.75 inches high , making it a low-profile support cushion , not a thick padded seat booster. It is best suited for office chairs, desk chairs, and similar seating where subtle contouring and light cushioning are preferred. A breathable mesh cover promotes airflow and is removable for cleaning. A non-slip bottom helps keep the cushion in place, and the built-in handle makes it easy to move between seating areas.
