You can use the Maxi-Cosi Minla 6-in-1 Essential Gray from the birth of your child up to the age of 6 years old. With 9 different heights, 4 tray positions, and the adjustable backrest, you can easily adjust the high chair. Your newborn can lie down comfortably in the chair with the included seat reduces while your toddler can sit upright at the dinner table. When you detach the seat from the Minla, you can use it as a booster seat too. Thanks to the attachment belts on the bottom, you can secure the chair onto a dining chair. Did you little one spill their carrot puree all over the seat? You can easily unzip the cover and wash it in the washing machine. After use, you can collapse the Minla 6-in-1 to create a compact package.
