Features to consider while buying Crib Mattress

There are various features that should look into before you buy a crib mattress for your child.

  • When speaking of the skin or cover of the mattress, there are two types of covers generally available in the market, first, fabric, and second, vinyl. Both of these above-mentioned materials have their uniqueness when it comes to breathing. Vinyl covers have breathing holes for better air circulation while fabric naturally breathes better. The vinyl covers are usually multi-layered thus making it more durable than the fabric covers, which have higher chances to get ripped off or punctured. So while shopping for a crib mattress, customers are suggested to look for triple-layered design which increases the durability of the mattress.
  • If the buyer wants to buy a complete waterproof crib mattress, he should go for a vinyl crib mattress. But before buying, they should check for the air-pockets as proper air circulation is very important for the longevity of the mattress.  The waterproof cover of the mattress keeps it stain-free and the outer toughen layer gives extra firmness and support to your infant.
  • If you are planning to buy a crib mattress, always buy a new one. It is preferable to avoid a second hand mattress. Old or second-hand mattresses can be infested with bacteria which can adversely affect the health of your baby. Secondly, worn mattresses lose the firmness hence making it unsafe for your child.
  • You should also take into consideration the weight of the crib mattress. According to legal guidelines, the innerspring mattress should weight around 20 to 30 pounds whereas the foam mattresses are lighter and should weight around 6 to 9 pounds. If the weight differs largely, it is preferable not to buy.
  • Speaking legally, the size of a crib mattress should be 27.75” x 51.75 inches.
  • Some mattresses in the market are labeled as ‘flip crib mattresses’. This means they are two-stage crib mattresses and as the name suggests, they can be flipped to support different stages of your child’s growth. One side of the mattress is firm, specialized for the infants and the other sides are softer for the toddlers. It is always suggested to concern a child specialist, who can correctly guide you about which side of the mattress is correct for your child.

Types of crib mattresses

There are different kinds of mattresses available around us. If we divide the categories of crib mattresses broadly, we can find three types – foam mattress, innerspring mattress, and natural mattress.

  • Foam Mattress

Foam mattresses are not only lighter in weight than the innerspring mattress but also cheaper, hence this mattress is more popular among the buyers. Foam mattresses are specially designed for infants to avoid Sudden Infant Death Syndrome (SIDS). Unlike a memory foam mattress, which tends to create a void by the infant’s head, thus increasing the chances of suffocation, the foam mattresses are firm and retain the shape.

  • Innerspring Mattress

An innerspring mattress uses coils of steel, covered with a layer of foam. The better the quality of the mattress, the heavier it is and the more durable it will be.

  • Natural mattress

Today if anyone searches for crib mattress online or any local store, they will surely come across ‘organic’ or ‘natural’ mattress. These mattresses are made up of natural materials like latex of natural origin, wool, cotton, fibers of coconut, foam derived from plants, and so on. Natural or organic mattresses are not pocket friendly hence they are not everyone’s cup of tea.

Below is a list of the top crib mattresses available along with the best crib mattress protector and the best crib mattress topper for you to help you make an informed decision.

How to choose a crib mattress?

Choosing a crib mattress for the infant can be very exhausting, confusing, and tricky without proper knowledge and guidance. It does not matter from where and at what price you are buying the crib mattress; these tips will help you to choose the correct one.

  • Research

If you don’t research, you can’t expand your options about brands, quality, material, price, usage, how to maintain it, availability, and many more. The more you research the more you learn about the advantages and disadvantages of various types of mattresses.

  • Size

Before buying any crib mattress, you should know the exact size of your crib, in which the mattress will be placed. As per the golden rule, there should not be more than a gap of two fingers between the side of the mattress and the frame of the crib. A larger gap than this can be enough to trap your baby in between and suffocate him.

  • Air circulation

Fabric mattresses breathe naturally and better while vinyl mattresses have air pockets to increase air circulation. Whatever mattress you choose, it should have a proper air circulation system. With proper ventilation, moisture escapes the mattress thus making it odor-free and more comfortable for the baby sleeping on.

  • Firmness

A firm mattress is necessary for the safety of your baby although it sounds uncomfortable. Soft crib mattress often leads to SIDS or Sudden Infant Death Syndrome. A soft mattress can suffocate your baby hence a firm mattress is what your infant needs. You can choose a ‘flip crib mattress’, one side of this mattress is firm, fit for your infant and the other side of the mattress is soft, perfect for your young toddler.

  • Certificate

Always go for government-certified brands to buy mattresses, for they follow the safety rules made by the government.
