The foldable sensory table and everything built to go with it. The table is the centre of the system — it folds flat, grows with your child, and holds two bins under a lid that doubles as a whiteboard and chalkboard.
Around it: chairs sized for the same kids, leg extenders that raise the table as they grow, spare bins and lids, and the padded travel bag the folded table slides into for the closet, the car, or the next classroom.
Everything here is designed to work together, so you can start with the table and add as you go rather than replacing it in a year.
