The Lifetimer Tri-Lite is the world's first table of its kind. It transforms in seconds from an adjusting table to a pediatric table to a sturdy two legged bench/stool. The quick pin locking legs allow for table height adjustability from 14.5 (great for toggle technique) to 20.5 in two inch increments. Optional leg inserts boost table height to 22 and 26 high. The push button headpiece has five positions. Table is accompanied with molded carrying case on wheels. Airline friendly!!
