Babies will spend up to 70 percent of their time in their crib. So its very important to spend some time and pick the right crib mattress. There are lots of materials that mattresses are made out of. Some are made out of foam, springs,latex,or other natural fibers, or a combination of these. Certain models are even made to be hypo-allergenic. Here are a few essential tips to finding a crib mattress online.

The main differences to take into consideration when deciding, is the the construction, size, firmness, and cost of these mattresses. It does not matter which type of mattress a person buys for their newborn as long as it is firm and not soft. It must also fit so that there are no gaps between it and the crib.

The mattress must not sag at all or have any signs of wear and tear. So it is recommended to buy a new mattress not a second hand one. Cheaper ones tend to have less springs and foam than more expensive ones, so you get what you pay for.

Foam mattresses are normally the cheapest kind. Most of the time they have a washable cover around the foam, which is easier to keep clean. It is best to choose one that is at least 4 to 6 inches thick, so that the baby is supported properly when sleeping. Some will have ventilation holes in them but it does not matter if they have not. Most foam ones are lightweight.

Innerspring mattresses are made with coiled springs in the center which are usually covered with foam or cotton. We recommend that you select a mattress with a wipeable or washable cover. There is a wide price range on these depending on the other materials used in the mattress.

Natural fiber mattresses are gaining momentum in the industry. These natural mattresses are typically made with latex, organic cotton, and sometimes coconut coir. The latex has its advantages because, they are hypo-allergenic and resistant against dust mites, mold, mildew, and fungus. They are a good choice if a person is worried about their baby sleeping on synthetic material. These ones are long lasting and hold their shape well. They are normally more expensive than the foam or spring versions, and are harder to find.

A person should measure the crib and get the exact measurements for each mattress they are considering buying. Then work out which ones will fit the crib without any gaps around the edges. If the person can get a few fingers between the crib and mattress, then it is not a good fit.

Firm ones are best for newborns and softer ones for toddlers. There are some available with one side firm and the other soft, so it can be flipped over depending on the firmness that is needed. Some can also have an anti microbial coating on the surface. This will reduce bacteria and germs from the babies saliva, vomit and bed wetting.

By Law in the United States all mattresses use a fire retardent.  Many manufacturers, to cut down on costs, use a retardent made of very harsh chemicals.  Certain mattresses offer retardents made of organic materials which are less harmful to your baby.  When getting ready to purchase your crib mattress it would be helpful to read reviews of other parents and buyers.  Hopefully these tips will help you select the right mattress for your baby.
