Settlement is one of the most frequently reported issues. A mattress will lose a certain amount of resilience in the first few months and this is a normal characteristic. It is also common to experience backache or sleep restlessness particularly if this is the first replacement bed the customer has had in many years.

ISM craftsmen will explain product characteristics to the customer and explain that the mattress is wearing normally if the ingress or dip is less than the industry standard of 5cms. They will assure the customer that there is no cause for concern.
