We only sell quality mattresses sourced from the world's best & trusted independent manufacturers. They are quality tested & comply with British Standards. The mattresses are cleverly shrunk down for ease of handling & shipping by vacuum rolling them into a polythene roll. As with all mattresses it may take a few days for your mattress to settle to its correct shape once opened & for your body to adjust to it. New Mattresses sometimes smell rather strange initially, this smell is normal & will also disperse after a few days. We strongly recommend that you are sure of the mattress you are purchasing & that it will be suitable before ordering & advise on researching thoroughly beforehand. Because of their nature, mattresses are difficult to return once they have been taken out of their packaging. We will only accept responsibility for the return of a mattress if there is deemed to be a genuine manufacturing fault upon inspection. A mattress that is stated as being 'uncomfortable' is not deemed to be a manufacturing fault & merely depends on the individual & their past & expected sleeping experiences. It is worth noting that for a person to become accustomed fully to a new mattress can take some time.
