"If there is anything that characterizes a high-level office furniture manufacturer, it's the design and innovation of their more technical products. Research and innovation that takes into account the new uses and needs of today's society is what allows each new model to surpass the previous one, in terms of benefits and services. Investing in health is an investment in the future, in concentration, in efficiency and, as a result, productivity. All this is possible by investing in ergonomics." - Marcelo Alegre, Alegre Design

In order for a team to be at its best, you need to take care of its members with solutions that provide comfort while preventing problems resulting from bad posture. TNK is a technological platform whose industrial base has allowed for the design of different task seating models for work environments where quality, comfort and ergonomics are fundamental aspects. Solutions that promote well-being, that take care of individuals and contribute to making them happy so they can enjoy doing their job.

We know that passion and consistency are keys to success, which is why at Actiu we develop new products that are the result of intense research whose main goal is to guarantee the comfort and ergonomics of work spaces, in addition to facilitating different postural options that can provide users with freedom of movement and can therefore improve the physical conditions of their job. Welcome to the age of well-being, at work.
