Width
The width of a crib mattress is typically 28 to 30 inches, which is just over two feet. This mattress size is standardized so that all cribs will accommodate the same width, regardless of the brand or style. The width of the mattress should be snug against the sides of the crib so that there is no gap where your baby could become stuck.
Height
The standard crib mattress is six inches thick, although some mattresses are as thick as eight inches. The thickness of the mattress is a personal preference, but keep in mind that a thicker mattress will be more expensive and may not fit in all cribs. Some parents prefer a thicker mattress for their baby’s comfort, while others find that a thinner mattress is just as comfortable and easier to move around.
The height of the average cribMattressis approximately 28 inches, although some brands may be slightly taller or shorter. The height of the mattress is important because you want to make sure that your baby can not climb out of the crib. A taller mattress may be more difficult to get in and out of the crib, but it will provide a barrier between your baby and the floor.

Innerspring
Innerspring mattresses are the oldest and most common type of mattress. They consist of a steel coil support system with layers of padding on top. The number of coils and the gauge (thickness) of the wire varies by manufacturer and model, but most have between 300 and 850 coils. The amount of padding also varies, but most innerspring mattresses have at least two different types of padding, including a layer of cotton batting or fiberfill.
Foam
Foam mattresses are a type of mattress that is made from foam, rather than springs. They can be made from a variety of different materials, including memory foam, latex foam, and polyurethane foam. Foam mattresses are often considered to be more comfortable than spring mattresses, as they contour to the body and provide pressure relief. However, they can also be more expensive.
Organic
Organic mattresses are made with certified organic materials, such as cotton and wool, that have been grown without the use of pesticides or other chemicals. These mattresses are often more expensive than non-organic options, but they may be a good choice for people who are looking for an eco-friendly option.
