The Risks Associated With Buying A Crib Mattress

Purchasing a crib mattress is not as simple as going into a store and choosing the cheapest one you find first. Infants are very sensitive when it comes to sleep and what materials they are exposed to. The primary cause for concern with buying a crib mattress is the risk of Sudden Infantile Death Syndrome (SIDS). This sudden death can be caused by a few factors to do with choosing the wrong crib mattress:

  1. Soft Foam – a firm mattress is what an infant needs to ensure that they can develop a healthy posture throughout the remainder of their lives. A foam crib mattress that is too soft will not only promote poor posture but dramatically increase the risk of suffocation to the child!
  2. Chemical Additives – in recent studies, SIDS has been strongly associated with toxic chemical additives that are added to crib mattresses. These include flame retardants, heavy metals (like mercury or lead) and phthalates. These compounds are toxic to humans in general but exposed even in small quantities to infants; they can be fatal.
  3. Allergic Reactions – some infants have allergic reactions to synthetic materials, even when they are non-toxic. For those of you who are naturally allergic as parents, it would be best to buy an organic crib mattress for your children to sleep on.

Standard Crib Mattress Types and Specifications

Did you know that crib mattress sizes are regulated in the US by the Federal Government? The standard size of a crib mattress is 27.25 inches by 51.62 inches. Crib mattresses should also not have a thickness of more than 6 inches. These measurements conform with standard crib sizes, which usually stem around being 28 inches by 52.37 inches.

Crib mattresses are divided into two main types:

  • Innerspring Crib Mattresses – these are mattresses with coils wound in them. These mattresses are usually better to buy because they hold a firmer shape. You need to make sure that the springs are individually wrapped, However, as a loose spring can be detrimental to an infant’s development.
  • Foam Crib Mattresses – foam crib mattresses may seem comfortable at first, but cautions need to be taken to ensure you don’t end up buying one that’s too soft or that contains harmful chemicals. Non-toxic, high-density foams make the best crib mattresses because they are firm enough to prevent the risk of suffocation.

A combination of these two types works the best, leaving no chance of infant suffocation.

Features of a Good Crib Mattress

Here is a list of the best crib mattress features available today:

  • Waterproof – a waterproof crib mattress is a great feature to have because they are much easier to clean if the child makes any mess.
  • Breathable – it is advisable to have a breathable mattress so that your child does not perspire. Many box spring mattresses are breathable. However, foam mattresses are not. If you want to purchase a foam mattress, make sure to get cotton covering so that the crib mattress allows your child’s skin to breathe properly.
  • Cotton Layers – Cotton is very soft, breathable, and easy to clean. Having cotton layers in your crib mattress is a great way to add a firmness that is entirely non-toxic and back supportive to the baby.
  • Antimicrobial – especially for those that are allergic to things, an antimicrobial mattress is useful to prevent bacterial or fungal build-up that can make your baby ill.
  • Temperature Regulation – A form of temperature regulation or a Tempurpedic mattress can greatly improve your infant’s sleeping experience. This can also mean the difference between your child sleeping through the night versus waking you up every few hours! If the crib mattress does not regulate temperature very well, it will overheat, which can cause other potential problems for the baby.
