IKEA Table Top (£80 RRP).
Dimensions: 140cmx65cm
I have used it for my standing desk for the past year, however it is slightly too wide so I am downsizing. Would be a shame to see this go to the tip.
The original guide holes are untouched (4th pic). However there are a few additional guide holes on the bottom side which I have made.
It has grommet holes (60mm) pre drilled and fitted, great for cable/wire organising.
