K&M 23875 Dual monitor mount

The monitor stand is sturdy and we'll built and has been in place for a year now with monitor changes. Occasionally during the night I heard the set up creaking, the screens shake when I walk in my room, I left pillows on my table for fear of them falling. They have been solid - but they didn't feel like they would be - would recommend for smaller / lighter monitors, but not for large heavy monitors. I also used a book on my table to distribute the pressure as I was afraid the material on my table was not strong enough to sustain the pressure at a small pressure point
