WALI Dual Monitor Stand: A Solid, Space-Saving Base Camp
Size: Dual, Style: Free-Standing
WALI Dual Monitor Stand: A Solid, Space-Saving Base Camp
I needed to reclaim some real estate on my crowded desk, and this WALI freestanding mount did the trick. It's a straightforward, no-frills solution that holds my two 24-inch monitors securely and opens up a ton of space underneath.
Assembly is intuitive, though having a second pair of hands is helpful when you're attaching the monitors to avoid any tipping. The all-metal construction feels sturdy and reliable. The adjustments are basic but effective—you can raise or lower both monitors together on the central pole and tilt or swivel them individually to get the angles just right. The included cable management clips are a nice touch for keeping things tidy.
The key thing to understand with any freestanding mount is balance. If you extend the arms all the way out toward you, the whole unit can get top-heavy and want to tip forward. I keep my monitors positioned more centered over the heavy base, and it's perfectly stable. It's not meant for dramatic, extended poses.
For the price, it's fantastic value. It doesn't have the infinite, fluid adjustability of high-end gas-spring arms, but it doesn't need to. It lifts your monitors, frees up your desk, and does its job without any fuss.
Bottom Line: An excellent, budget-friendly way to lift two monitors and dramatically increase your usable desk space. Just be mindful of the center of gravity and don't expect ultra-flexible, independent positioning.

Easily supports a pair of 26" displays
Size: Dual, Style: Free-Standing
I have no complaints with this stand. It is not as nice as the Inland brand sold at MicroCenter, but it does its job. It beats the price of the MicroCenter one, thats for sure.
It comes with all the hardware you might need, even long screws and bushings if you have a display that needs them.
Assembly was quick. It comes mostly assembled anyway. You have to put the bottom on the post then attach the assembled arms to the post.
Setting up can be a challenge but with help, its easy. After mounting the bracket on the back of the displays, you just slide them into the receiver on the arms.
Once mounted, adjusting the position is simple, but can take a while as there are several joints which can be positioned to angle the displays as you like.
The cord clips do an OK job of cord management, but the clips are not as good as the Inland ones. They do the job, but not as durable. I broke the one that goes on the post, but I tried getting it to hold a wad of wire. My fault.
I recommend this stand.

It's simple, it works, & its price makes for a good deal
Size: Single, Style: Free-Standing
I needed a stand for a 27" VIZIO TV that had been wall-mounted for a few years, & (?) the original stand must've got the toss long ago... It's hard to say...
I found this stand on Amazon priced right, plus it had a coupon attached to the listing. I scrolled down & I saw a "newer model" of the same product was available, so I was initially hesitant.
But, looking at the product pictures, reading the description, & scanning through some of the reviews, then the same with the "newer model" — the only difference I could see was mostly aesthetic (it also appears to have a desk mount included, which wouldn't have worked for me regardless of its purpose—either for conversion to a desk stand-off mount, or to further secure the stand....?)
Eventually, I just thought "....it's a stand with a VESA mount; how do you **** that up...?" And I really couldn't think of anything...even if the VESA bracket was milled not to spec (it is milled to spec), I could
have still made it work....(?) So, I made the purchase, received it, & 9-10 screws later, the TV had a stand. & I'm guessing a much more versatile stand than the original. The bracket that attaches the stand to the VESA mount can lower or raise the TV quite a bit. Even in it's highest position, it's still retains its sturdiness & remains stable. The baseplate has a decent amount of weight, and its overall design is well balanced to favor stability (to a tolerance; e.g., an old CRT monitor just isn't going to work).
The stand is literally 4 basic pieces—the VESA bracket, an articulating bracket, a metal tube, & a metal baseplate. If you have a standard phillips screwdriver, then the stand is easy to assemble. If you have any experience with TV mounts, or TV stands, then it assembles in less than 15 minutes.
Given what you get for the price, the ease of assembly, the added versatility, if you need a stand for a screen within the manufacturer's specific tolerances, then I would absolutely recommend this stand.

Decent Monitor Stand with Some Assembly Required
Size: Single, Style: Free-Standing
This monitor stand works pretty well and is a good value for the price. It’s sturdy and adjustable, which makes it perfect for a variety of monitors, including my 32-inch curved Samsung. The assembly is straightforward if you have a Phillips screwdriver and something to tighten bolts, like a wrench. It’s solid once it’s put together and holds my monitor securely. The phone holder could use some improvement. It doesn't adjust to face me directly, which is a bit annoying. The stand itself is great for saving desk space and providing better ergonomics, but it can be a bit of a hassle to assemble if you’re not handy with tools. Overall, a good buy if you need a reliable monitor stand.
