Hi,

I'm building a desk by fixing a sheet of laminated MDF to a wall along a
2x2" strip that runs the length of the back and one side of the desk, with
aluminium tube legs as support at the front.

The floor of the room (1st floor, timber boards on joists, 100 years old,
just hardboarded and shortly to be carpeted) has an incline of up to
2cms/metre along the direction of the length of the desk. The desk itself
will be quite long (2.5m at the back and 2m at the front - it's a trapezoid
shape a bit like this

I'm just about to mount the 2x2" to the wall and was wondering whether
horizontal with gravity or horizontal with the floor was best.

On the one hand, horizontal with gravity will look better below the rows of
shelves I've fixed to the wall above desk height, on the other I suspect
that horizontal with the floor will be more comfortable to sit in front of -
after all, my chair and I will be horizontal with the floor. Computer
keyboards will be placed on the desk and so I feel having one side of my
body lower than the other is not good posture. But horizontal with the floor
will look pretty awful over 2.5 metres, just below a shelf of equal length
mounted horizontal with gravity.

Short of pulling up the floorboards and relevelling the floor (carpet
fitters arrive on Tuesday), what would you do?

Thanks.
