All new mattresses are designed to settle or dip slightly in the areas that you sleep the most. The layers and fillings are simply responding to pressure point areas (shoulders and hips) and providing support where you need it.

It usually starts to show within the first few weeks of use although don’t worry it does not carry on at this rate.  

Body impressions are a positive indication that the generous amounts of upholstery fillings on modern mattresses are conforming to your body's unique shape and weight.

While settlement is no cause for concern, there are a few ways you can minimise this if you wish.

The NBF recommends that you make sure your base is supporting your mattress as any dips or weak spots in your base will make settlement worse. They also recommend you follow the care instructions supplied with your mattress to prolong its life and minimise the effects of settlement.
