I'm trying to build my first large desk for my computer setup. My plan is to set a 74" × 42" laminate counter top on top of four Alex drawers and I am concerned about the center of the table sagging or breaking without an apron for support. I drew a top down view of the table quickly and was wondering what I should add for support to strengthen the center if needed. The countertop, The drawers, The design Most of the weight will be located near the top of the table with three monitors. Other than that I'm planning on having just a keyboard, mouse, and maybe some light nick-knacks scattered throughout.

  • Hi, welcome to StackExchange. It's not clear from the text, what do the blue lines represent in the diagram? I don't think you'll have a problem either way, but it may be worth clarifying that.

  • The blue lines represent the gap between the Alex drawers. I only made those to see what space I would have under the desk. Aug 26, 2022 at 21:35
  • Ah good, just had to check whether they were some sort of apron pieces.

  • Guessing you mean “without an apron for support…”?

Laminate countertop material is very stiff. 46" is just over 1m and such spans are normal in many kitchen designs. After 1 year of use I expect laminate will deflect, but you will not notice (maybe 1-2mm).

If deflection can be seen after many months easy to install central leg same height as Alex drawers for support.


That counter top is 1 1/8" thick so it should be fine across that span.

If it deflects more than desired, you could add angle irons between the front and/or rear sets of the red boxes (green lines in the drawing) to stiffen it up a bit.

Reinforcements added to orig. drawing

You might want to add this reinforcement anyhow if there's a chance that someone will sit on the desk. Again though, I think the manufactured thickness is adequate for this case, but I'm not very familiar with the quality of Ikea components.
