If you don't find your mattress comfortable, we would be happy to change it for you. Please contact our Customer Service Team on 0344 292 0000, or Submit a Request before 40 days from delivery to arrange for an exchange to a different mattress. A new delivery charge will apply and any difference in price will be payable at time of difference. If it's cheaper, we will not refund the difference in price. Don't forget our stores are here to help with any questions you may have.
