Most experts agree that from a design perspective ergonomic office chairs that have four or fewer points of contact with the floor will be inferior to a five legged base.
In order to ensure proper support and avoid tipping we recommend looking for an ergonomic office chair with a five legged base.
You also should think about whether or not you want casters. That is informed on the type of work you think you will be doing. It is fair to say that most modern office chairs whether in the office or at home have castors. Given that the working hours have increased there is often a need to reposition the chair and also work in more flexible spaces and that means it is more advantageous to move your chair easily. When it comes to the castors, thought needs to be given as to whether you will be on carpet or a hard surface as that may influence your choice.
An example of an ergonomic office chair with a five legged base is the SIHOO Doro-C300.
