With classroom Internet access nearly universal in public schools and computers ubiquitous on every school and university campus, classroom furnishings have evolved to accommodate the machines so students can take full advantage of the technology. The desks, tables and other furniture that a school chooses for its computers will depend on the types of machines being used, but the key features most sought after are comfort, mobility and flexibility. For computer users who expect to spend extended amounts of time in front of a monitor, having comfortable seating that wards off fatigue or injury is crucial. In a computer lab, a school might have to accommodate students of differing ages and sizes, so having furniture that is flexible and adjustable is paramount. For administrators selecting furniture, the growing prevalence of school laptops means shifting from computer workstations used to accommodate desktop machines, and looking at easy-to-maneuver mobile carts that can hold and transport a classroom set of laptops throughout a school.
