The local Community Team for Learning Disabilities purchased a suitable low chair. A welded “H” frame was made and fitted between this chair and the original wheels. Two scissor type mechanisms were constructed with torque bars to ensure that the seat elevated evenly. A 12mm screw jack powered by a 12-volt cordless drill motor powered the raising of the chair. When down the chair was at its original height but it could be raised by the required 110mm.
She was able to take herself to the toilet without assistance.
