Why are Bassinet Mattresses so Thin?

Why are bassinet mattresses so thin and hard? The short answer is for babies’ sleeping safety. However, there’s a little more to it than that. Parents have plenty of worries when it comes to the first few months with their baby, and one of them is that they are going to break their head on a bassinet mattress. Even if you don’t know anything about sleeping safety guidelines or what’s best for your child, we want you to be able to make an informed decision so here are some facts about those mattresses.

Bassinet mattresses can come in different thicknesses but generally range from ¼ inch up all the way to 1½ inches thick. Most bassinets sheets will fit over any size because there isn’t much variation between the different bassinets models.

For the safety of newborns, parents should make sure that the thickness of their crib or bassinet mattress is less than one inch. This prevents infants from sinking into a soft surface and being at risk for suffocation. After all, most bassinets mattresses are thin to allow babies room to breathe even if they end up on their stomachs while sleeping.

Mattresses are designed for infants to breathe, even if they end up face down. For this reason, most bassinet mattresses have a thin and hard design because it is dangerous for an infant to sink their head into the padding which increases their risk of suffocation.

How Thick should a Bassinet Mattress be?

The perfect thickness for a bassinet mattress is no more than 1 ½ inches. A thicker one can lead to suffocation. Although some bassinets come with hard and thin mattress padding, parents don’t have to complain. They are specifically designed for babies sleeping safety.

According to ASTM (The American Society for Testing and Materials), a thinner or harder mattress in bassinets may reduce the risk of SIDS (Sudden Infant Death Syndrome).

The Bassinet sheets are designed to fit 20″ x 28″ mattresses while Crib Sheets are tailored at 24×42.”

The mattress for a bassinet is important to ensure your baby has enough firmness while sleeping. Just like with crib mattresses, the dimensions of the bassinet also need to be followed closely. Your little one’s face should not sink into it and their head needs space from touching any sides or roofing above them. The perfect sleep surface would have just an inch in height as well so they can’t roll over onto their stomachs too easily without waking up on time intervals due to being suffocated by other heavy pillows surrounding them at night – which you don’t want either!

The bassinet mattress should not be heavily padded to avoid the baby’s face from sinking in. The sleep surface for babies should be relatively hard so that they won’t have trouble breathing, and it also helps with their posture development due to being too soft on a hard surface like wood or metal (which can hurt them when they rollover).
