An adjustable height table has a frame with spaced apart side portions spanned by a horizontal tray with a knee area below the tray. Each side has a foot that engages the floor or like support surface. Each side includes a lower non-elevating base part and an upper elevating “lift” part. The non-elevating and elevating portions each have an outer wall, a hollow interior and vertical slots that face in opposite respective directions for a given side (including a non-elevating portion and an elevating lift portion). A gear mechanism interfaces the upper “lift” and lower “base” parts. When the table is in an extremely elevated position, roller supports minimize lateral translation. The roller supports fit shaped rails on the elevating parts. The frame can receive any of three selected mechanisms. Each mechanism features a horizontal shaft contained within the tray. The mechanism includes a counterbalance spring that can be used to counterbalance loads of different amounts such as when different objects are supported by the table work surface, a motor drive that changes elevation using electrical power, and a manually operable crank mechanism.
