What to know before buying

Listing details to confirm

The listing is inconsistent about construction and comfort: it describes a gel memory foam layer over high-density foam, while the specifications variously say memory foam fill, gel memory foam comfort material and gel foam construction. The headline calls it medium, and a separate firmness field also says medium, but it does not clarify how this translates to feel. The listing also calls the cover removable and machine washable without giving washing instructions. It claims a 9-zone mattress and washable cover in an item highlight, but the explicit included-components list names only a manual, so any extra kit remains unconfirmed. Check the selected listing for the exact construction and contents.
