Product Overview

Reliance 558 Stool

Bottom-line comfort and maximum variety

The 500 series is designed for optimal stability during the most delicate surgery. In this line there are five options, so you can easily find one that suits your needs.

Foot Activated Hydraulic Foot Pedal

Enables physicians to position themselves without breaking the sterile field.


Exceptional Stability

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.

Ergonomic Design


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



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.



Height Hands Free A convenient foot pedal easily raises or lowers the stool height without using hands. Total vertical travel is 7½’’

Finished for Durability


All exposed metal, with the exception of the aluminum base casting, is anodized aluminum and stainless steel. Base castings and legs are finished in tough, black epoxy enamel.
