Reliance Model 558 Hydraulic Adjustable Stool
The Model 558 was designed to provide maximum comfort and support for the practitioner’s back, arms and wrists. The seat on the
Model 558 swivels 360° independent of the base so that height isn’t affected. Swivel of stool seat may be locked by lifting foot pedal. For
extra lumbar support, the upholstered backrest adjusts vertically, tilts forward and locks in place.
Foot Activated Hydraulic Foot Pedal
Enables physicians to position themselves without breaking the sterile field.
The Model 558 comes standard with specially designed floor lock to prevent chair movement during surgical procedures. In addition,
five legs distribute weight evenly and ensure stability. The circumference of the base also exceeds that of the seat to further maintain
stability, even in the elevated sit-stand position. Mobility is provided by rugged 2½’’ casters molded from hard rubber.
Upholstered armrests support the practitioner’s forearms. For comfort, they adjust vertically and lock in place. For convenience, the angle of the arms adjusts and locks into place, then rotates to the rear upon completion of the procedure.
Adjust Height Hands Free
A convenient foot pedal easily raises or lowers the stool height without using hands. Total vertical travel is 7½’’
