Crib Mattress Dimensions


It’s easy to get confused about all the different types of crib mattresses. Some mattresses are waterproof, while others have “antibacterial” fabrics. There are even crib mattresses with built-in speakers, to play lullabies for babies as they fall asleep. However, a simple crib mattress needs to be both safe and effective. Here are some tips about crib mattress dimensions, and how they affect your baby’s safety.

Safety First

When choosing crib mattress dimensions, you always should consider your baby’s safety first. It may be hard to believe, but not every crib mattress is a safe choice for your child. Actually, some types of crib mattresses with improper dimensions could even cause your baby to be at risk for injury or death. To keep your child safe, you need to think about safety. Your crib mattress dimensions should exactly match the dimensions on the inside of your baby’s crib. Having a good fit for your mattress is essential for ensuring that your child stays safe inside their crib.

Do Mattress Dimensions Affect Price?

The answer to this question is both yes and no. It’s true that some crib mattresses with thinner dimensions may be less expensive than some other types of crib mattresses. However, there are also thin crib mattresses that are made of higher quality materials. The size of the crib mattress, and the crib mattress dimensions do play a small role in the mattress price. However, they aren’t the single defining factor to consider when budgeting for a baby crib mattress.

What are the Proper Crib Mattress Dimensions?

Not all crib mattresses are a good fit for all cribs. There are several factors which may influence your crib mattress dimensions, including:

Shape of Crib
Baby cribs come in many different shapes, which may mean you may have to look for a special kind of crib mattress with special dimensions. For example, there are circular cribs, oval cribs, rectangular cribs and square cribs. Each of these crib shapes will require different crib mattress dimensions.

Type of Crib
A portable crib may need different crib mattress dimensions than a full-size crib. Depending on the type of crib, you might have to use a different type of crib mattress. Smaller cribs, or cribs with thicker sides may need crib mattresses with special dimensions.

Age of Child
Did you know that babies do best when placed on a firm crib mattress? However, for toddlers, a softer, thicker crib mattress may be better. Depending on the age of your child, you might have to use a crib mattress with different dimensions.

Personal Preference
Some parents simply like to choose the best crib mattress dimensions for themselves. Thinner crib mattresses may be denser, or they may be less expensive. Crib mattresses may also have other features, such as a waterproof cover or antibacterial properties.
