here is the stand up computer desk that I made from a book case. I cut 5 inches off this book case . And when I put my laptop on top , the screen is at my eye level. If you are sitting all day at a computer desk your head and shoulders lean forward and put too much strain on your neck. Doctors are now calling this "TEXT NECK", because many people get this condition because they lean forward and put their head down to read their phone.
