This table provides the simplest, smoothest height adjustment available. Popular Furniture uses a counter balance system that allows the table to "float" up and down, offering you the perfect work height for every situation, with no compromises. Once you've found the right height, an easy-to-reach knob securely locks the tabletop in place until you're ready to adjust it again. This table is great for therapy, as a reading/activity table, or in a corporate break room.
