SmartFit System simplifies finding your personal comfort setting. Just find your color, and dial in your ideal height and tilt-angle setting (up to 50°). The greater the angle, the more you increase air circulation to dissipate heat and keep the laptop cooler, which eases strain on the battery and internal components. Padded inserts provide non-slip stability for any compatible laptop, keeping it firmly and safely in place while you work. Designed to quickly and easily fold flat, so it saves space in your bag when you're traveling on long or short trips.
