Product Description SEAT REDUCER WITH REINFORCED SIDES The Alpha Cosy Comfort is particularly useful during your toddler’s first months in the hauck wooden highchair. The practical seat reducer comes with an extra high back and reinforced sides that protect your child’s head, while also offering stability and comfort. The seat cushion’s cotton structure is very soft to the touch, providing your baby with a breathable and temperature balancing seat that prevents heat accumulation and offers optimum comfort even on warmer days. The snuggly seat cushion comes with an anti-slip coating that prevents it from sliding back and forth during your little explorer’s mealtime and playtime. Also, the seat minimizer is compatible with both the 5-point harness and safety strap that come with the hauck wooden highchairs. The Alpha Cosy Comfort is designed for the hauck grow-along chairs and fits them perfectly. It is very easy to install and just as easy to remove for washing. The seat reducer is compatible with the Alpha Tray, as well as with various other Alpha+ accessories, allowing your little one to use them at the same time. Box Contains 1 x seat
