A dispenser for dispensing sheet material from a roll. The roll has a location arrangement for releasably mounting the roll between a spigot and an oppositely facing support element for rotation about a longitudinal axis of the dispenser. The arrangement includes: a core around which the sheet material is wrapped, one end of the core being mounted or mountable relative to the support element, the other end having a wall region defining a generally hollow cylindrical portion projecting from the wrapped material, a generally axial slot being provided in the wall region extending to the free edge thereof; and a fixing provided on the cylindrical portion. The fixing has a bearing surface for rotatably engaging the spigot for rotational movement about the longitudinal axis, and a radial path to the bearing surface, the path being radially aligned with the slot in the core, whereby the end of the core may be laterally engaged with the spigot support element.
