I purchased for two reasons. My (older) wrists were uncomfortable both at home and using a mobile computer at work. For my home laptop, the larger rest has been an excellent length and shape to offer wrist support when using my laptop at my desk. The hard edge of my desk was painful, but no longer an issue. I haven't had discomfort with the mouse, only the keyboard.
For my work usage, I was experiencing the same issue using a mouse on a mobile computer stand. I placed the smaller rest in a clear ziplock for infection control as it is fabric, and not able to be sanitized. I change the bag at the end of my shift. (Two guesses what my occupation is.)
It too, has made such a difference in wrist comfort. This set is offered in some nice colors to coordinate with an office, but I chose the gray color as it blends in and is neutral. Excellent purchase!
