The Furniture 49 Glacier Desks were developed for traditional and progressive teaching styles to help implement 21st Century Learning concepts into the classroom. Optional casters make these desks easy to pull apart for individual study and testing purposes, or to move into multiple group configurations. In a group configuration, these desks fi together snuggly with no wasted space and can be rearranged to maximize the use of limited space commonly observed in today’s classrooms. Full frame construction takes the wiggle out of learning.
