It is our goal at Tiger Medical to provide you with all accessories that will improve the quality of life for the medically and physically challenged. We have therefore brought you products by OH-4 - manufacturer of the The Nearly Universal Cupholder. OH-4 is a family owned business that created a cupholder that can be used with almost any armrest. A welcome addition to scooters, chairs, stadium armrests, and airline armrests, the OH-4 also extends the armrest for your convenience. Tiger Medical is happy to partner with OH-4 to offer you their top quality cup holder. Please feel free to contact our knowledgeable sales representatives for any questions or to place an order.
