A mattress 12 for a bedding unit comprises a first support surface 16 and a second support surface 18. Each support surface is configured to support a user thereon and each have a different level of firmness, e.g. soft or firm. At least one top portion 15 is removably attachable to either of the first or second support surfaces of the body. The at least one top portion has a level of firmness less than the level of firmness of the first and second support surfaces such that when the top portion is attachable to either of the first or second support surface, the level of firmness of the first or second support surface is reduced. An overall level of firmness of the mattress can be altered by the user selecting either the first or second support surface alone or in combination with the at least one top portion to provide the overall level of firmness of the mattress that is acceptable to the user. The mattress topper may be attached to the mattress by means of a hook and loop fastening or a zip 19, 23. |
