Understanding Heavy Duty and Bariatric Office Chairs



What is Heavy Duty and Bariatric?

Heavy Duty chairs typically are built with components to support heavier users.
In the past “Heavy Duty”, traditionally started around the 130 kg mark. At Ergolink we believe the Heavy-Duty range starts at 150 kg because from here you can be sure the weight rating and its ability to last.
Please be cautious.  Some manufacturers are now claiming some of their basic chairs are now in this range. Even though theoretically the chair can support this, certification and registration can sometimes be missing.
Bariatric chairs are typically in the higher weight capacity and can be sourced with a weight rating over 250 -275 kg and over 300 kg.


What makes them Heavy Duty?

In a nutshell, manufacturers make the chairs from components that are designed to support the weight. These parts can include:
  •   Heavy duty Castors
  •   Heavy duty Gas Strut
  •   Heavy duty Mechanism
  •   Alloy or reinforced base
  •   Larger reinforced seats
  •   Suitable seat foams and gels
  •   Fixed arms
It is the combination of these and the testing and certification that makes a chair heavy duty or bariatric.

Consider the Seat size and foams

Seat size is critical in this range also. Some manufacturers offer custom made seat sizes to around 720 mm wide. For larger users, comfort is critical and the wrong seat size may often cause more issues than you started with.  
The same can be said for the type of foam or gel used in the seat and back. Poor quality foams may crush and not disperse weight evenly. Apart from Reduced comfort, this will significantly reduce the life of the chair. Research the options available.
