The Maxi-Cosi Lila Stroller features an ergonomic memory foam inlay for your newborn (from 0 to 4 months). The ShapeOfYou inlay reduces the space around the body providing babies with a feeling of security. The cushion also lifts the legs into a natural position, helping to reduce reflux. The shaped cavity reduces pressure under the head thereby helping to prevent flat-head syndrome. The integrated nap keeper creates a unique cocooning atmosphere for your baby offering protection from bright sunlight and mosquitos. The reversible mattress keeps toddlers comfortable throughout the year regardless of the temperature; breathable 3D mesh for the summer; soft fleece for the winter. The one-hand folding system also makes the stroller very convenient to collapse and store.
