I got my own desk custom built, its made up of kitchen worktops - there really smooth and have the rounded edges. I have two pieces cut together into a corner of the wall, there held to the wall using some nice sturdy wood.

Although moving it would prove to be hardwork, i could jump up and down on it and it wouldnt budge
