The Silver Moon is the name for the core range products so it has all the features mentioned on the Pocket 1400 section of the website. The Adlington is made exclusively for Tesco, whilst it has the same number of pocket springs & a deep layer of latex, this product doesn't contain Aloe Vera & the overall look varies from the core range product. Again the Hartwell which is available exclusively in Argos has a different look again & Aloe Vera is not included.
