At the end of the day, all you want to do is lay in bed, but some people still may have unfinished business to attend to. This is where a bed desk comes in handy. These are rolling desks that are flat and made to slide over your lap so you can do paperwork or be on a laptop. Usually, these have a surface that can be tilted to avoid neck and eye strain.
While you are in bed or another comfortable spot, you may find that trying to work on with papers or your laptop is a bit uncomfortable. This is why the lap desk was created, to allow ease and comfort. You can relax comfortably without slouching or straining and still be able to do what you want. This is preferred to using a desk by the bed, as you cannot keep good posture, and must strain your neck to see what you are working on.
Of course, bed desks can be used for other, more leisurely activities, such as reading a book while in bed. For most people, books can get a bit heavy after holding them up for a while, especially when they are hardcover. By tilting the surface of the desk, you can turn it into a bookstand. By using this feature, you can lay in bed comfortably while reading your book, without tiring your arms out.
These desks could also be used when you are feeling under the weather, to hold food while you rest. Unfortunately, unlike bed trays, these desks do not have the special holders that prevent food from spilling. Therefore, you would have to be very careful not to spill anything, or you will possibly feel hot food or cold drinks spill on you, or have another mess on your hands. The possibilities for using bed desks are endless.
