A head support (10) includes a resilient body section (16) having a body interior (20) and an outer layer (22), and a plurality of raised projections (18) that are positioned on the outer layer (22). The projections (18) extend away from the body interior (20). In one embodiment, the projections (18) have a higher coefficient of static friction than the outer layer (22) so that the projections (18) inhibit relative movement between the outer layer (22) and a surface (14) when the projections (18) are in contact with the surface (14). In another embodiment, the outer layer (22) has a first side (24) that generally faces the surface (14) and a second side (26) that is substantially opposite the first side (24). The body section (16) has a length (30), a maximum height (36) and a width (34). The width (34) is less than at least of the length (30) and the maximum height (36).
