This comforter lap desk is exactly what I needed, a way for me to sit comfortably on my bed using my laptop without it overheating. I've tried many products, from Targus cooling pad to Logitech... For $29.99, this product is my holy grail. The rubber cushion is great, perfectly rests on my lap. Very comfortable. The curve lets air into the space between my laptop, not letting it over heat. I dont have to do anything at all to get comfort, no overheating, and very effortless. This is the one that I will use on my bed, and I also have the I100, which I like to use on desk.
