An apparatus for dispensing paper product stacked along a stacking dimension includes a housing for holding the stack of paper product and having a longitudinal dimension associated with the stacking dimension. The movable ejector is located adjacent the housing and is configured to contact paper product at an end of the stack. Movement of the ejector is effective to slide paper product at the end of the stack, relative to a remainder of the stack, in a dispensing direction, to thereby dispense paper product from the housing. A first restrictor in the housing is configured to exert a force on the stack in a first restricting direction transverse to the dispensing direction, with the first restrictor being spaced from the ejector, in the longitudinal dimension, by a first distance.
