I am currently decorating a room which is going to be my office and there is a 2m space for a computer desk. I am thinking of ordering a solid oak worktop to use as the desk (2M X 720 X 40mm ~46kg) and was wondering what sort of legs/support this would need to prevent any sagging? Currently I have two IKEA Alex Desk Drawers for my current desk, would it be possible to use these?
Would there need to be anything in the middle? My monitors are going to be mounted on the wall so there shouldn't be much weight directly in the middle, just my PC on the right hand side.
I used a sag calculator (does this mean two legs/support either side should be acceptable) :
