Like all of ezpz's products, the Mini Mat is an all-in-one placemat + plate that suctions to the table. Designed for infants / toddlers 4+ months. It is ideal for travel. Important Notes The Mini Mat does not fit on the following highchair trays: the Stokke Tripp Trapp, the Boon Flair, the Nuna Zaaz, the Keekaroo, the Ingenuity ChairMate (Easton), the Safety 1st Beaumont and the Abiie Beyond Wooden Highchair. The high-gloss finish of the Oxo Sprout Highchair hinders the Mini Mat's suction function.
