The Lean N Learn Wedge Cushion gently tilts the hips, pelvis and spine forward to place kids in a more active seating position. With improved seating posture, kids are ready to learn and can focus for longer periods of time. Two-sided design offers smooth surface on one side and tactile bumps on the other for sensory input when needed.
