It is generally accepted that from a design perspective chairs with four or fewer points of contact with the floor will be less stable than a five-legged base.
In order to avoid the hazards of inadequate support and tipping we recommend looking for a base with a five legged base.
The other consideration is whether or not the chair should have casters. Whether that is the case depends on what type of work you are predominantly intending to carry out from your chair. The vast majority of chairs in the modern office or home environment will now tend to have castors. That is due to the long hours spent in the chair and the need to re-position the chair relative to the task and bending to reach various computer components. The consequences of not being able to carry out these tasks without appropriate casters are likely over time to lead to fatigue and muscle strain.
Our other tip is to take a few moments to actually consider the caster itself. The main division that you might be looking for here is what surface you are working on, i.e. is it carpet or is it a hard surface. Most office chairs are fitted with carpet casters. It can be worth your while in taking a few extra moments to cast your over the chair specification to check what is said about the casters.
