It is nearly impossible to cozily work on a PC without a proper computer desk. You would be straining the body in several crazy situations and you would consequently get the work done at a slower speed. To find a really useful-shaped computer desk, there are several characteristics that exist to get the greatest use out of it. One of the best useful features of an l-shaped computer desk is a gliding keyboard shelf. These are attached below the main surface and glide out while in use.
There are several really nice features of this shelf such as the keyboard is safely kept inserted away till required, releasing up workspace. A second advantage is that the keyboard is in a more ergonomically friendly location. Having your hands and arms a few inches lower than on top of the l-shaped computer desk is more comfortable and natural. If you don't have a laptop or an all in one PC, you probably possess a separate CPU and it would actually be nice if you had extra space to keep it somewhere other than on top of your l-shaped computer desk. You could keep it on the floor, but it is better not to keep a costly element on the floor. Most good l-shaped computer desks have a shelf or additional area that is particularly designed to keep the computer safe and sometimes they have a place for the printer.
