The Tavr single monitor stand is a free-standing riser that uses a 1.5mm thick cold-rolled steel pillar and an 8mm tempered glass base. This design is useful for renters or those with desks that don't allow for clamps, as it leaves no marks and requires no drilling. The stand is designed for screens from 13 to 32 inches and uses a slide-and-click VESA plate for easier assembly.
The weighted glass base helps prevent the monitor from tipping, providing a lower center of gravity than lighter plastic stands. Height is adjusted manually by loosening a bolt on the back of the pillar. For monitors at the larger end of the size range, tightening the tilt nut firmly with the included hex key helps keep the screen at a steady angle.
If you need to support a heavier setup with two screens on a single base, the Hemudu Vertical Stack Stand provides a similar free-standing approach for dual monitors.
You can find more single and dual screen mounting options in the modular monitor stands section.
