We actually adjusted this and used some parts of similar style console table to extend the desk as it had to accommodate a storage pouffe when it didn’t have the chair in use, we also changed the laminate for old fence panels that we had and because I’m short had to trim the legs slightly.
The frame is stable despite the extra weight, actually looking to purchase a second and do the same alterations again when it comes back to stock so that myself and my husband will both have a proper desk for work. 
Just enough detail that it isn’t a boring square frame but doesn’t impact functionality at all.
