Also going to chime in and say I've got one with monitor arm (only one monitor mind) and bookshelf speakers (also not a lot of weight). No wobble after 2 years

Also going to chime in and say I've got one with monitor arm (only one monitor mind) and bookshelf speakers (also not a lot of weight). No wobble after 2 years or so. When assembling I did feel that the actual attachment of the surface/board was a bit cheap. They used plastic positive tension pokey... things. Not sure what you call those. I suspect if you have to disassemble / reassemble it a few times they may wear out and the top may wobble independently of the base.
