Product description: We all work for hours in front of a computer, yet may not even consider if we have the right posture. An ergonomic desk set up helps with neck, back and shoulder discomfort most computer users suffer from due to bad posture. Raising the monitor to an ergonomic height allows the eyes, the neck and shoulders positioned in their optimal state for reduced stress. Mount-It! developed this single monitor desk mount to offer maximum flexibility with height and depth adjustments for your monitor. It attaches securely to your desk with a clamp or grommet base and comes with a gas spring assisted arm to raise and lower the monitor with a light touch. With the use of the arm height adjustment and the 14" pole, the monitor can be raised as high as 28" over the desktop. We also developed a top-mount base that can be secured to the desktop from the top, removing the need to crawl under your desk to attach the monitor mount. With quick-disconnect VESA head, you can easily mount your monitor to the arm, saving you from inserting the screws to the back of the monitor while holding it up on the arm.
