The bassinet mattress pad doesn’t have to be so hard that it’s uncomfortable and difficult for your baby to fall asleep and stay asleep; it just needs to be firm.

Thickness
If your baby’s bassinet mattress pad is too thick, it could pose another risk for suffocation. But if it’s too thin, it won’t be comfortable for your little one. The right amount of thickness is important for both safety and comfort.

The bassinet mattress pad in your little one’s bassinet should be no more than one and a half inches thick. Anything thicker could be a hazard.

Fit
Traditional oval- or rectangular-shaped bassinets measure about 30 to 33 inches long by 15 to 18 inches wide. On the other hand, some bassinets have their own dimensions.

Before choosing which bassinet mattress pad is best, pay attention to the shape and size of your baby’s bassinet. In order to provide the safest sleep environment, the bassinet mattress pad will need to fit snugly inside the bassinet.

If you don’t have the correct dimensions, this won’t be possible. So before you begin your search, make sure to measure your little one’s bassinet.
