Tyke Supply Super Quad Free Standing Monitor Stand

Very sturdy for only $114. I've set up a quad monitor configuration on a stand that cost $200+ before and the only benefit was the more expensive stand came in pre-assembled. The arms on this stand are great, they can flex to almost any angle you need them to and they don't move unless you want them to.

This was easy to install, works perfectly and is exactly as it is described. Would recommend it for a "compact" display needed for a somewhat confined space.

no clamp and this actually holds tighter and doesn't move when I move my 27" monitors. I love this addition to my office.

I have this stand, and I use it with 4 x 24" Viewsonic monitors. It actually works best with the outer arms removed, so that the monitors are closer to the wall. I suspect that 28" monitors will need the outer arms, but for mine, they cause problems. Luckily, they are easy to remove. Like other reviewers, I also had problems with the rubber padding on the bottom of the base, which was rolled up when the box arrived. I spent $0.99 at Michaels to buy new padding, and a $5 can of spray adhesive at Home Depot to replace the rubber padding with higher quality material, so it is now good. I sent Tyke Supply a note about this, but have yet to get a response. The stand is quite stable with 4 x 24" Viewsonics.
