The Constructa cushion for the Wonderseat is built for very young children whose postural needs change quickly. Its inner components are modular, so the thigh supports, ischial well and contour can be rebuilt as the child grows or as their posture shifts.
That adjustability matters most where asymmetry is emerging. A cushion that can be shaped to accommodate an uneven hip angle helps hold the pelvis level, and a level pelvis gives the trunk and head a fair chance. The ischial insert and overlay spread load away from the high risk areas at the same time.
Size 0 covers the smallest end of the Wonderseat range, so it suits toddlers and preschoolers in a tilt-in-space chair who need real postural work done at the seat base.
