From instructables.com:

I don’t think it is a good idea to watch TV or use laptop in the bedroom. Each room has it’s function. A bed is made for sleeping in.

Lots of people use their laptops in bedt, as it’s more comfortable for me. H

Materials Needed:
-wood strip, 1.9 cm in x4.4 cm x 182.9 cm. Just about anything of the right size will do.
-hard board, MDF board, etc - I used MDF the first time due to the clean white melamine coating, but the plain hardboard looked better and seemed more durable.
-two knobs attached to screws/bolts
-two big washers
-two socket anchors
-2 very short wood screws (for the lip)
-4 medium wood screws (for the legs)
-4 small nails
-4 plastic checker pieces (optional)

Tools:
-circular saw (could use a hand saw, but it’d be messy)
-power drill
-(Optional) dremel w/ sander bit
