The POSI222BK is the perfect solution for transforming any home or office setting into an active workspace. Its medium size allows you the flexibility to sit and stand for computer use, while providing you with traditional desk space when you need to put pen to paper. The keyboard tray can adjust to a desired angle for a more ergonomic & comfortable setting by using the locking adjustment dials. The POSI222BK raises and lowers in the forward position of the main deck, providing comfortable and easy access without having to bend or stretch. The durable gas springs mechanism accommodates up to 33 lbs, allowing you to transform the desk quickly and easily with one touch. The "Smart Rail" keeps mobile devices front and center while you work. The holes in the bottom of the Smart Rail allow charging cables to be attached while staying out the way. Adding the flexibility to raise and lower your workspace empowers you to take control of your work day. Posidesk provides a solution for making your environment happier, healthier and more productive.
