The Back-Up is the most popular product and the subject of most scientific research and testing over the past 4 decades. Its extra cushion thickness makes it the choice for ''terminal sitters" as well as those of larger body frames. With sensible use, NadaChair slings can be safely used all day. While many report immediate relief of back strain due to slouching, support benefits continue as long as the product is worn. As with any product, new to you, you will experiment with adjustments for sustained sitting comfort. 

The Back-Up comes with CushShin accessories that distribute leaning weight over approximately three times the area of the shin.
