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