The HA90LB lift back table can be used during exams, therapy, or mobilization. It can be elevated to an ideal working height so the doctor does not have to bend and stress his or her back as much. The adjustable height also helps the patient get onto the table. The height is adjusted with a foot pedal to between 22 and 35 inches and glides smoothly and quietly. This table locks at any angle up to 80 degrees when you let go of the button. All of the mechanisms are inside the chair to provide safety to all parties involved. The standard model of this table comes with a 24 inch wide top and one and a half inches of foam. There are a number of extras, including a face cut-out, different height ranges, and an extra foot medal, that can be added to this table to meet your needs.
