Very pleased with my new writingwork desk . The desk can be arranged so the shelves are on either side just by moving the bottom brace bar and turning the desk around. The desk went together quickly and easily it took myself less than an hour , a small screwdriver is provided but I used my cordless driver . If you use a power driver set the torque very low as the desk frame although sturdy once put together is made from 1mm mild steel and can be put out of shape by over tightening the screws . A spare screw of each size is provided just in case you misplace one and the picture instructions provided  were easy to follow . free next day delivery and the easiest flat pack furniture I’ve ever put together.
