The Fisher-PriceÂ® Sit-Me-Up Floor Seat is comfortable for your baby and super-convenient for you. The soft fabrics and wide base of this infant chair help support your baby as you sit them up to interact with the world around (and those two adorable toys!). And the best part? It folds flat, making it easy to store or take with you as you travel! Where development comes into playâ Security & Happiness: A comfy and supportive upright seat on a wide, sturdy base lets your baby see and interact with their surroundings (and you!). Gross Motor: Reaching for the toys and pulling them up to play encourages gross motor skill development. Use only with a child who is able to hold their head up unassisted and who is not able to climb out or walk.
