My Dad has advanced Parkinson's disease and has reached the point where he can no longer get out of his chair and into his wheelchair without assistance. I'd like to get him a chair or chair lift to provide assistance to him (and me!) Does anyone have any recommendations for either chairs or chair lifts? The stand alone units seem to have terrible reviews and the prices on the chairs vary wildly so I am not sure what to do. Any thoughts or recommendations would be most appreciated!
