I have previously used a Ikea Skogsa in conjunction with my Maidesite standing desk legs, but after 6 months I experienced the dreaded sag. After taking the worktop off the legs I noticed at least a cm of sag in the middle. After looking through this subreddit I decided to give it another go but this time make sure it to reinforce it properly. I previously thought that I wouldn't experience sag as I used the 73" variant but this wasn't the case.
- Many people in this subreddit suggested using angle iron for support however I opted to use Galvanised 41mm x 21mm x 2.5mm Slotted Channel Struts – this came in handy later with cable management.
- As the holes in this strut were bigger than expected I had to use M8 washers to overcome this.
- I used 30mm length PZ woodscrews to mount the struts.
- Although it wasn't necessary, I mounted a 600mm x 145mm piece of redwood to the rear of the desk, to help disperse the weight of both my monitors arms.
- Finally, I mounted 2 cable trays to the rear of the desk, and the worktop to the standing legs.
If anyone else is considering this setup I would recommend swapping out the standing legs screws for proper wood screws, and using washers on the center bar to ensure it is snug, for added stability. I only noticed after taking apart my first attempt how inadequate the stock screws are for this use case.
If anyone has any questions, feel free to comment below. I will be updating this subreddit in years to come to provide updates on the sag.
