The Nolah Original, Signature, Evolution, and Natural all feature one comfortable and durable sleep surface, eliminating the need to flip the mattress. You should only sleep with the top side facing up, as directed in the setup instructions.
However, we do recommend you rotate your Nolah mattress by 180 degrees every three to six months. This will ensure you use every inch of your mattress and extend its lifespan.
Our Nolah Nurture kids' mattress does have a flippable design and features two different firmness levels on the opposite sides. This allows your child to switch between the plush and firm sleep surfaces as they grow, depending on their current comfort and support needs.
