Swivel Mechanisms

Gaming stool swivel mechanisms are available in two formats to create either a fixed-height or gas height-adjustable stool.

Although the fixed-height stool is the more traditional option, stools fitted with gas height adjustment are becoming increasingly popular as players demand greater ergonomic comfort. In addition, design improvements have resulted in gas lifters becoming more reliable and cost effective, so many venue operators are now insisting that their new casino chairs are fitted with gas height adjustment.

At Karo, our unique component-based modular design allows users to select either option.

A Heavy-Duty Swivel-only or Swivel-Return mechanism on your casino chair allows either a full 360˚ rotation, or 180˚ rotation with an automatic ‘spring-back’ feature. The latter option is ideally suited where ease of getting on off the stool, together with neatness on the gaming floor, is a priority. Which is better….swivel-only or swivel-return?

A Gas Height adjustment mechanism allows 360˚ rotation in addition to height adjustment. Gas lifters for gaming stools are available in various ranges, typically providing 80 to 140mm of adjustment.

Gas height adjustment for gaming stools has been available for many years. Unfortunately they have somewhat of a poor reputation, predominantly due to the unreliability of the gas lifters when they were first fitted to casino chairs in the early 1990’s. At that time, malfunctioning and leaking gas lifters were commonplace and they were soon replaced by the more traditional non-adjustable fixed-height swivel mechanisms.

While there is little doubt that any stool or chair fitted with gas height adjustment is more comfortable than one without, it is only in the last few years that gas lifters have regained popularity as improved designs have contributed to fewer failures and greater reliability.

In fact, modern gas lifters now rival traditional fixed-height swivel mechanisms in terms of both price and reliability.
There are 2 broad categories of gas lifters suitable for gaming stools, viz.

a)   Standard gas lifter

This is the simplest and most popular gas lift option. Like any office chair, the standard gas lifter will allow the gaming stool to be raised and lowered by means of an actuating lever. When the patron gets off the stool, the stool will remain at the height to which it was last adjusted i.e. it is possible that the stools on the floor will all be adjusted to different height settings.

b)   Swivel-Return and Self-Raising gas lifter

This is a more complex gas lifter that not only operates as a Standard Gas Lifter, but has two added features. When the user gets off the chair, the gas lifter will automatically extend to it’s maximum height while simultaneously rotating to a neutral position. This means that when the stools are not in use, they will all be set to the same height thereby improving the neatness of the gaming floor.

Benefits of gaming stools with gas height adjustment:

 1.   Safe and easy to operate.
 2.  Extremely Reliable. Modern gas lifters from reputable manufacturers are extremely reliable….a far cry from the reliability issues experienced in the past.
 3.  Vastly improved comfort and ergonomics. The inherent damping effect of a gas lifter ‘cushions’ the impact when initially sitting on the stool which can prevent injuries to the lower back and/or coccyx.
4.  Gas height adjustable stools can be used for both slant-top and standard height gaming machines.
5.  Easy on-site replacement.
