The Classe A3 Plus chair has been designed to combine simplicity and flexibility. The basic unit is robust yet stylish and provides the dentist with everything they need. However, should the dentist want to add features or devices, this is possible and the chair can be customised to suit the individual needs of the dentist. There are a number of ways the dentist can adapt their chair and they can add new modules or instruments as they wish.

The chair can be adapted for left and right handed dentists and a version with a shorter arm is available for those working in smaller spaces.

The International Version has been designed for dentists who like to use hanging tubes and a sixth instrument, such as a T-LED or C-U2 intra oral camera, which can be added.
