VIVO Pneumatic Arm Dual Ultrawide Monitor Desk Stand for Up to 49 inch Screens with Tempered Glass Base, Holds 2 Ultra Wides Up to 30.8 lbs, Black, STAND-V249FG

This is literally the only freestanding multi-monitor stand I could find on Amazon, and it works perfectly. I needed a stand that didn’t require clamping to the desk, and this one delivers exactly that. It is very sturdy and durable, with no wobbling or stability issues at all. What surprised me is that the range of motion of the arms is just as good as any clamp-on or gas-spring stand. I can tilt, swivel, and adjust the monitors freely without any resistance issues. It’s flexible enough to dial in the exact viewing angles I want. The value for the price is excellent. Even considering the tempered glass base and metal support plate, the stand remains a great deal. The build quality and stability you get at this price point are hard to match. Overall, this stand meets all my needs — freestanding, sturdy, adjustable, and cost-effective. I couldn’t be happier with the purchase. Highly recommended for anyone looking for a strong freestanding multi-monitor solution.

Works great after adjusting the ark sensitivity and pressure thanks vivo

I didn’t want to consume the surface my desk with a clunky keyboard/monitor riser. This was a perfect alternative. For my keyboard riser, I use a spice stand that’s meant for a cabinet! When I’m sitting down, I just slide it forward and out of the way then place my keyboard & mouse in front of me on my giant mouse pad!

This is by far the closest product that can support what I need without it having a clamp mount. Clamp mounts especially for nicer tabletops can easily crack them if there's a ton of weight and you're adjusting the tension on the monitor arms. This solves that issue by having a giant metal + glass plate. Having the ability to do side by side, and stacked in two different configurations is wonderful. Makes the stand so much more future proof. 30.8 lbs per monitor is definitely good enough for the next decade at least... Two gripes: screwing the base together with the pole is insanely difficult, definitely need one person to hole the pole and the base while someone else screws it in. The other one is the monitor quick releases. It's awesome to have a quick release plate, but it is not so awesome to constantly have to be adjusting the set screws to make sure that you have enough tension on there for arm to not move when installing. Definitely recommend 2 people for this as well, but it is possible by yourself.

I have two 34" monitors mounted and it's holding great. Easy to reposition monitors as you want

Well, for $150, the quality of this product is pretty disappointing. When considering the positives - the stand certainly holds the weight of my two (2) 49" curved Samsung monitors stacked on on top of the other. The arms were a bit fiddly to tighten - I was afraid of breaking the tension screw with too much torque, but I was able to tighten them enough to stabilize them. Assembly was very easy, and one person could assemble it and mount the monitors with minimal effort. On to the two (2) negatives: The base consists of a heavy metal plate on the bottom, and a tempered glass base above it. You don't see the metal base, it's (mostly) covered by the glass portion. Unfortunately, one would expect that the metal base and the glass base align squarely with each other. That doesn't happen, and the metal base is out of square by about 1/4 of an inch, so a portion of the metal base extends out from under the glass on the left side. Sort of annoying if you're a perfectionist. The other issue I have is the arms, while fully articulating, don't allow you to perfectly align the monitors above each other. For example, the top monitor is about 1" to the right of the lower monitor. A bit annoying as well. I've only had this stand in use for a day, so maybe I'll get used to it. Given the effort it took to assemble and mount the monitors, as well as rearranging my workstation, I'm going to keep it, but just wanted to share the observation that QC and design could have been better.

Easy installation and great functionality. Very happy with purchase choice.

Awesome thing. Holding my 30” Eizo and LG C5 42” strong as Captain America’s shield. Going to put another big one later. The fact that its on the table is amazing.
