A:AnswerTop = 20.5" wide x 11.75" tall with rounded corners. The top has a tray ledge to hold the laptop when the top is tilted. There is a smaller tray ledge to hold the mouse when the top is tilted. The top can be locked into place flat, or levers released to adjust it to incremental tilts up to about 45 degrees. The legs can be fully extended to make the top 12.75" off the ground (level top) and can be shortened in incremental heights down to 9.25" (level top). If the top is tilted to 45 degrees the front edge is 5.5" off the ground (maximum tilted top) and if the legs are fully extended, the front edge is 8.6" off the ground (maximum tilted top). The legs stand centered on two supporting feet that are 11.25" long and one inch thick. The legs fold up like a card table for easy transport. I can put it into my carry on luggage.
A:AnswerThere are screws on it so maybe you can. I’m not sure. But you don’t have to use the fan. It has a short USB connecting wire. I don’t use the fan and the fan is not in the way at all.
A:AnswerThe width between the legs is 19.5 inches and the table top where the laptop would sit is just over 20 inches. I don't think it would be effective sitting it in top of your legs.
A:AnswerI dont completely understand your question. Think of this like a TV tray...but maybe a little taller. It will not reach from the floor to the couch. It would sit on the couch with you.
A:AnswerI purchased mine when it was Deal of the Day so you would have to check back when it becomes deal of the day. They also have sales like black friday or labor day, but it's best to check back since eit changes.
