Why use Moulded Foam?

The type of seat foam used in office chairs has an impact on their price and comfort. There are two basic types of flexible seat foam, namely Moulded Foam and Block-Cut Foam.

At Karo, it is our mission to improve the comfort of our chairs by including moulded foam in the design of all our seats. Widely used within the automotive industry, this type of foam has long been recognised by ergonomic experts as being able to deliver the best support and cushioning for any person that sits for an extended period of time. If you are looking for a quality office chair, then moulded seat foam is a definite “must-have” feature.
