looking for something to soften the sharp edge of a laptop - the edge your wrists might rest on.
I find when typing I dont lean on that edge, but when surfing I do - which causes wrist problems.
Roll up a bath towel and secure it into a roll with some hair elastics
. Use the stretchy terry type that resemble sock loops, not rubber bands (rubber bands wear out and pop too easily). Then set it in front of your laptop and use it as a wrist rest.
I use one made from a kitchen towel as a wrist rest for my mouse, otherwise the edge of the table or desk cuts off the circulation to my hand.
Or perhaps a piece of this stuff
, meant to cushion sharp table edges and protect small children, attached to the front edge of your laptop.
The only 2 problems with using that cushion stuff is that you'd probably not be able to close your laptop completely, and you wouldn't be able to clean it very well when it gets grimy. At least with the towel, you can undo it and toss it in the wash.
