The EL 2.4 is fitted with an extra high back which gives the chair status and lends itself as a managerial or executive chair. The extra high back is also ideal for tall people to ensure optimal back support.
We are not designed to sit at a desk for long periods of time. Even if you sit on a good ergonomic chair, it is often not used or set up incorrectly. The Axia Smart Chair was designed with this in mind.
