For the last 2 years David and I have watched TV/movies through our computer. Generally we have it on our laps, which makes it warm, or we have it sitting between us which makes our already small bed even smaller. So after a few days of processing and calculating I decided that I would make David a computer bed table for his birthday. College football started last week and I knew that this would only increase the frequency of watching the computer in bed, often times until 1 or 2 AM. So I went and bought a hand saw and some nails and started tearing apart a pallet.
It took a couple of hours and some adjusting but it now works. It isn't pretty but it will work for us for 4 months.
It has 2 legs that slide underneath the bed then the table is about 2 inches over us in the bed.
