A graduated set of pillows includes a plurality of three or more pillows. Each pillow is configured for a particular range of human physiological development and has a plurality of critical dimensions targeting proper postural support of persons in such range. For each critical dimension, a first pillow has a minimum dimension and a last pillow has a maximum dimension. The other pillows in the set have distinct dimensions that form graduated increments in the critical dimension over the set from the minimum dimension to the maximum dimension. Specific magnitudes of these critical dimensions may depend on the height, weight, head circumference, length of vertebral column, or neck circumference of an average person within a particular age range, for example. By providing such a graduated transition in each critical dimension, the set of pillows provides proper postural support for the gradually changing anatomical characteristics of developing persons.
