This portable laptop table is a very simple yet ingenious device. It is very light, small and relatively sturdy. It can easily support my big and heavy 17.3-inch Toshiba Cosmio laptop so that my knees don't have to bear this heavy weight. If your laptop gets hot (my other smaller laptop does) then this is also a perfect solution to avoid this problem. The table has movable legs which can be very easily set to the required angle/ level and folded away when the table is stored. There is enough space between my legs and the table legs, although for a much bigger person this may be a problem. You can comfortably place the table on the sofa without the fear that the laptop will fall down. Working on a bed is even better. Overall, a fantastic product which will increase your productivity and reduce discomfort of having a heavy or hot notebook on your laps.
