I have three 27" monitors on it and works fine. You may have to put a big mouse mat on it as the desk top is made up of 4 pieces and in my case I could feel the mouse move on it bit difficult because of the tiny gaps.
I suggest buying the frame and desk top separate. Links below.
@DeeKie - CJM Furniture is worth a try. I've used them a few years back to get office desks for two home offices. Just to confirm, the desks I bought were not the adjustable desks - just standard office desks
