Fellowes GoRiser is a portable laptop riser and part of Fellowes range of ergonomically designed products aimed at providing mobile warriors with the means of using their laptops in a more comfortable manner. It is capable of holding lalptops up to 17". What is different with the GoRiser and other laptop risers I have used in the past, including the Belkin Cushtop, is it is foldable and thus portable. Fold it up and carry it on your laptop bag for easy transportation. This product is part of Fellowes's Smart At Work campaign of increasing awareness on work ergonomics.
Unfortunately it isn't as simple as that.
If you are in need of a portable laptop riser I can recommend this. In fact I would suggest you get one if only because if you really do need to use a laptop on your lap, it is better to have this than having nothing at all. Just remember that it doesn't exactly improve typing comfort.
