i used to have problems with mine, i used it on my bed and the fan bearings broke, and after i got a new cooling unit installed inside, i no longer place it on any surfaces that might suck up fuzz or anything..... for surfaces that might create heat problems, i just put a binder under it.... the surface is pretty good for laptop usage, and if you need more ventalation, you can open the binder and fold the one side under, and then rest the back of your laptop ontop of the binder rings, allowing plenty of air to flow! you can even slide something under the other side of the laptop to keep it up as well if needed. there is plenty of little ways of settingit up to work best for you, best of all, it's cheap
