Developed with the guidance of physical therapists, the Upseat Ergonomic Baby Floor and Booster Seat encourages proper upright posture and is safe for a baby’s developing hips. The seat engages the muscles responsible for proper upright posture and safely splays your baby’s hips in a development-friendly position. The 3-in-1 design can be used as a floor seat for sitting up, a booster seat using the conversion straps and a feeding seat with an attachable tray (for four months up through two years). It’s great for feeding time and playtime. The lightweight design and convenient handle also allow for easy on the go. The founders of the Upseat originally developed the product for their son Jack, who was born with cerebral palsy. When they saw what it did for him, they were encouraged to make it available to other families.
