The SAFCO Xpressions™ Computer Workstation allows notes to be taken directly onto its tempered glass worksurface when using a dry erase pen. Its side shelf offers even more room to write on. In addition to these unique, modern features, the desk may be used traditionally, as the main surface easily accommodates a laptop and the shelf can hold books, binders, or other personal items. Suction cups hold these tempered glass shelves securely in place. Add on the optional keyboard tray SAF1940BL, which is sold separately.
