A dispenser for dispensing discrete sheets of interfolded media is disclosed. The sheet dispenser is provided with an elastomeric cover which defines a perimeter and a cover opening located within the perimeter through which a pack of sheets can be installed and through which individual sheets can be removed. The elastomeric cover can be resiliently deflectable between a resting state in which the elastomeric cover extends generally parallel to the base and a deflected state in which the elastomeric cover bends in a direction towards the base. The elastomeric cover is bent into the deflected state and into the interior of the dispenser by the media pack during installation of the pack and return to the resting state once the media pack has been fully installed into the dispenser.
