It's simple. You can test the Emma mattress for 200 days to decide whether or not you are satisfied with our product. If you realise that Emma is not right for you, simply contact our customer service team ([email protected]) to arrange a pick-up date and issue you a full refund. However, we do ask that you give yourself time to get used to your new mattress so we recommend testing Emma for at least 3 - 4 weeks before sending her back.
