In either position, the table top is rigidly secured to the base for stability and the adjustment between positions is accomplished without removing the top from the base. Folding seats may be folded into a very tin profile for storage beneath the table top when not in use. A novel upright support is also disclosed which may be removably mounted onto the table top for use in supporting equipment used in laboratory work.
