Ekbacken desk idea
So I'm considering turning my old room into a home office, and part of it was that I wanted an L-shape desk. The original idea was to use my old 47" Lagkapten and buy another 55" one, and reuse my Alex drawer at the other end, but since I wanted a dual monitor set up and would need to clamp my monitor arm to my desk, I changed my mind about the Lagkaptens since they're honeycomb in the middle.
Now I'm considering using a 74" Ekbacken, Karlby, or Saljan countertop on top of my current Alex and a 2x4 Kallax turned longways on its side. Under the Alex was going to be some furniture legs so I can clean under it easier (my dog pees all over my stuff annoyingly) and under the butcher block was an Olov. I made a mockup of this in Sketchup; I know there's about a 1-inch difference between the butcher block and the Kallax but I can live with it.
My main concern is just the overall weight. Is the Olov leg going to be enough for the middle of the desk to bear weight and keep from sagging? Should I be worried at all about all of the weight on the Kallax and/or Alex drawer? If anyone else has a desk set up like this, I'd love to see it as well since this is my first time trying this coming from a 47" lagkapten/Alex desk.
