Not all mattresses need turning. But, if the manufacturer advises it, you should turn and rotate your mattress end-to-end weekly for the first three months. After this, turning and rotating every three or four months should be enough. This will help the fillings to settle more evenly. Some memory foam mattresses need rotating only.
You should alternate between turning the mattress over and rotating it from top-to-tail to ensure even settlement. If your mattress has handles, use these to position it on the divan base.
Although our 'No Turn' mattresses will never need to be turned over, we recommend that you rotate the mattress from end to end regularly..
