The pillow includes a base, a support, and a pair of bolsters. The base overlies the seat. The support is disposed axially along the base and supports the tail bone of the user. The pair of bolsters extend axially along the base, straddle the support, cradle the buttocks of the user therebetween so as to assure that the support is held in place under the tail bone of the user, by minimizing lateral movement of the user.
