PUTORSEN 17-49 inch Premium Aluminum Heavy Duty Dual Monitor Arm for Ultrawide Screens up to 44lbs, Vertical Stacked Dual Monitor Desk Mount, Full Motion Dual Vertical Monitor Mount, VESA 75/100,Black

I have 2 x 35.5-inch widescreen curved Samsung 4 K monitors. You might get 2 x 36 inches, but no more, if you want side-by-side.The arm works to allow side-by-side.Super sturdy and well-built. The arm supports the weight and is adjustable. These monitors are heavy.It is effortless to assemble and easy to adjust to the correct weight tension; the tilt tension is super solid and adjustable as well.Cable tidy is super handy, and the desk space is free now, which makes this super worthwhile.As I am greedy, I also have 2 x 36 LG 4ks at Home, so I may get another arm for home as well.

Does outstandingly the job, quite expensive but for those who doesnt want to take any chances, with this you will play safe

This screen stack holder is high-quality and incredibly easy to install. It provides excellent stability even with multiple screens. Adjusting angles and directions is smooth and effortless—highly recommended!

It's pretty amazing, holds 2 somewhat heavy 27 inch monitors without breaking a sweat. But for some reason, the handle that attaches to the back of the monitor likes to tilt back for some reason.I believe it's due to the springs perhaps not properly calibrated, or that it requires some screw tightening action (in my case, some brute force resolved it). Either way, great investment. Highly recommend.

The quality is great, the material is sold. I had to return it because my 40” monitor kept tilting.
