Logitech Comfort Lapdesk
Belkin CushDesk
Belkin CushTop
Has won for us the Logitech because they send (is nunmal rum usually in the living room) looks is well padded, prevented by the curved bottom sweaty thighs (eg in the summer) and also by the curved top, also participates strange seating positions ( eg half Schneidersitz- a leg up, leg down :-)). At first we were afraid that the pressure at the resting areas by the curved bottom would be large, which has one year use but not confirmed (laptops're usually not so difficult) Another advantage of filing that it Laptop to high and slanted enough lifts to allow a fairly comfortable working.
In 2nd place came the Belkin CushTop tray. Also with it you can work comfortably because it has a soft padding and the laptop raises a good deal and easily anschrägt. Unfortunately it looks but, in our opinion, less chic and not bring the already mentioned advantages of a curved bottom with it. The skew is okay, but I liked better with the filing from Logitech. For these reasons, we decided against it.
On the last place came the filing Belkin CushDesk, which offered us too little benefits. For me it is only a heat barrier between the thigh and laptop. Both height, as well as tilt it hardly brings.
Who is looking for a good and email storage, the Logitech Comfort Lapdesk I would recommend. Alternatively, because this was not cheap, we found the Belkin CushTop also quite ok.
