To be honest, I had concerns about the product photos because I saw that all the laptops in the photos were small Apple laptops and the like. But I measured my laptop and took into account the length of this board before ordering. Just for reference, my laptop is just over 15.5 inches long. As you can see from the photos, I have enough space for a small bluetooth mouse. It is no problem for me. In the shape of my old board, it wouldn't be much more stable and comfortable on my feet or the bed. I saw another reviewer say the phone slot is big enough for a phone and a pocket, but they seem to have quite a bit small phone. I have a One Plus 7 Pro and it's a thin clear plastic rubber sleeve in the case that came with it so it's not bulky at all and doesn't fit in the slot. So the slot is pretty much useless to me. Padding material because it keeps feet cool.
