At Sleepah we went above and beyond to ensure quality and safety for our customers. We only use certified CertiPUR-US foam that is made without any harmful chemicals in the manufacturing of our mattresses. This certified seal also means that our mattresses must meet rigorous standards for quality, performance and durability, but most important safety. Additionally, testing has been completed to ensure that the mattress, sheet & foam are 100% lead and phthalate free. You, as a parent, can rest assured that we have your baby’s comfort and safety in mind when creating our double-sided mattress. You will feel good knowing that you are purchasing the best crib mattress for your baby! The tri-fold feature allows you to take the mattress on the go, so your child can have a comfortable Sleep. Included in your kit is a fitted sheet and a carry bag.
