NOTE FROM TRIGGER POINT PRODUCTS: The Ergo Nav is a wonderful product if you spend a lot of time surfing the web as it allows you to sit back in a comfortable position as you browse. We simply caution those who do a lot of typing as this configuration can be cumbersome. We want you to be happy with your purchase so we simply wanted to alert you to this. The ERGO NAV is the end result of Dr. Steve Jones efforts to eliminate the need to reach to the desk for the mouse. The secret of the ERGO NAV is that it places the mouse close to the operator. Eliminating the postural stress that accompanies reaching to the desk for your mouse helps reduce many of the stresses associated with using the computer. Years of testing and countless prototypes were involved in the development of this product. We truly believe that the ERGO NAV will make a world of difference for most computer operators.
