Designed with extra room for your growing baby, the Upseat Big is 30% bigger than the original Upseat, providing more comfort and support around the tummy and thighs. With wider leg openings, a deeper seat, and higher back support, this upgraded design ensures your little one is cozy and well-supported at every stage. Our trusted design, developed with input from physical therapists, promotes healthy hip positioning and upright posture, helping your baby sit up naturally while supporting their growth and development. The Upseat Big XL transitions seamlessly from floor seat to booster, complete with a removable, easy-to-clean tray that makes it ideal for playtime, snack time, or family meals.
