?Ergonomic Design?: The holder’s tilt angle is 15°, which is an ergonomic angle for both sitting and standing modes. Adjust it to a suitable height, then your eyes can look straight at the camera. This prevents you from bending over on the screen, thereby reducing neck and shoulder soreness. ?Sturdy & Heat Dissipation?: This computer riser is made of thick aluminum alloy, which is sturdy and steady. Its max load is 17.6lbs. The silicone mats on the top prevent your laptop from slipping, on the base prevent the stand from sliding over the desktop. The middle of the stand is entirely hollowed out to ensure the fastest heat dissipation. ?Used for Multi Purposes?: The stand can be used in the office when you need a lot of typing (external keyboard is recommended); can be used in the kitchen to display a recipe; in your room when you try to learn some dancing moves from video tutorials or practice yoga; in a meeting room when you join a workshop or make a presentation; it can even be used as a substitution for podium, etc. ?Adjustable Height?: You can simply pull the pole to elevate the laptop riser from 7-15 inches for your preference (PLZ DONT PRESS THE LOCK BUTTON WHEN YOU PULL IT UPWARD). However, you need to KEEP PRESSING THE LOCK BUTTON on the pole and push the pole downward if you want to make it lower. The max height is for people who want to shift to a standing mode to prevent sitting for too long. ?Broad Compatibility&Note?: Compatible with laptops/notebooks of 11-17.3 inches, including Lenovo ThinkPad, Apple Macbook Air, Macbook Pro, ASUS Gaming Laptop, Dell, HP, Chromebook, Acer, Samsung, and others.
