A bunch of folks have discovered that IKEA’s Numerär solid wood kitchen counters work great as a desk when perched atop either table legs or small office drawer cabinets. I decided to give it a try, and — aside from the trauma of carrying an 83lb hunk of solid wood from the car — can verify it works:
I didn’t bother to permanently attach the Numerär counter to the two legs (Vika Alex and Vika Annefors). The counter’s mass keeps it in place pretty well, and the friction from the (included) four rubber stops that sit on top of the two white Vika pieces means it won’t accidentally go anywhere.
