As an expected parent or a parent to a newborn child, you must be worried about his safety, at every step. A child spends most of his infancy period sleeping in his crib as an optimal sleep is vital for his growth. So the best crib mattress is the core facility that you need to provide your child with.

You must be choosy at this and can’t rely on any product out there. Once he grows a little up, he starts performing some manoeuvres so the bedding should be soft on the delicate body of the child but firm enough to support the same.

Let me hold your hand for choosing a perfect mattress that fits well in the crib and suits to your little baby.

The Importance of a Crib Mattress

A crib is the first bed to your child and if it’s comfortable it develops good sleeping habits in the baby. A child is just passing through a growing stage and is more delicate than we think.

The best crib mattress supports a child’s every manoeuvre without straining his bones or other body parts. This ensures a proper growth and keeps the limbs in proper shape.

At the same time, the market is full of crappy products that are not up to the standard in terms of safety. Don’t get trapped with them and only choose a mattress that fulfills the essential criteria.

To ease your job, I jotted down the essential characteristics of the best crib mattress with reviews. Just cross check your mattress with these guidelines before making a purchase.

Qualities That a Crib Mattress Should Possess

    • Firmness: Child’s safety is the foremost priority while buying a crib bed mattress and the firmness of the product directly relates to it. The mattress should not lose its shape once the child turns over in the bed.
    • Reason Being? If he/she rolls upside down and the mattress bends in, the babies’ nose is dumped into the bent area and can’t breathe. It might lead the child to suffocation.
This suffocation is a big factor for causing SIDS (Sudden infant Death Syndrome). The firmer a mattress is the better. Don’t bother even if the mattress appears stiff to you as your baby is able to adjust with it.

So to check the firmness, press the mattress, especially the sides and corners, with your hands, release the pressure and see if the mattress regains its original shape. If yes, then it’s an ideal choice otherwise just discard the idea of buying it.

  • Size: Choosing a mattress of a right size is a must as it should fit properly inside the crib that you own for your child. The space between the edges of the mattress and wall of the crib shouldn’t be more or less than two fingers.
If space is more the mattress is too small and will keep wiggling, if it is lesser, the mattress won’t adjust to the baby’s movements and will be hard to him.

As a general gauge, the ideal measurements should be of 27 ¼ inches in length and 51 3/8 inches in width and the thickness should not be more than 6 inches or less than 3 inches.

  • Chemical Check: A mattress goes through many chemical treatments during the manufacturing process. But before it is out in the market, it should be a cleansed product that is free of any harmful chemical substances. The material used should be non-toxic.
Most mattresses nowadays use Vinyl Layer for adding waterproofing characteristics to the product. But Vinyl is highly toxic in nature and hazardous to the environment.
Since Vinyl is a hard material so to soften it up Plasticizers Additives are used that releases harmful gases and eventually can cause various diseases to the child such as Asthma, Cancer, Liver & Kidney damage etc. So don’t forget to check the certification if the mattress is Chemical Free or Not.
  • Cover of The Mattress: The cover must be hypo-allergenic. As the cover will be in constant touch with the baby, you should be extra careful choosing one. It should have 233+ thread count and make of cotton fabric.The cotton cover is washable and easy to clean. If the desired cover is not available with the product itself, make sure it is available as a separate option.
  • Warranty: Although not a mandatory requirement in terms of child’s safety and comfort but it shows the authenticity of the brand. If the manufacturer is confident enough for following the manufacturing standards, he won’t hesitate to offer a warranty period. I suggest products with a warranty/guarantee period of a minimum of 6 months.

Types of Mattresses

Two types of mattresses are broadly ruling the market. The Foam Mattress and The Innerspring Mattress. Basically, these are the construction types of the fillings inside the product that is directly related to comfort, durability, lifetime and a baby’s health. Let’s explore them further:

1.Foam Mattress

This is an economic and cheaper option and lighter in weight as well. As the name suggests, “Foam” is used as the filling material that is obtained by adding chemicals to the polyurethane which increases its viscosity level and density.

The best feature of the foam is that it gets soft once it is exposed to some sort of heat and gets its shape back once it cools down. So once your baby sleeps on it, it absorbs the body heat and conforms itself according to the body contour that provides comfort and optimal support to the child.

Density is the key factor in determining the quality of the mattress. The denser the mattress, the better it is. As a rule of thumb, a foam mattress’s density should not be less than 3” and more than 6”.

Sometimes the density is not mentioned by the manufacturer. In such situation, the weight could be the saviour. A heavier mattress of the same size is denser than the one with lesser weight. No matter which product you choose the density should not be less than 1.5 pounds per cubic foot.

2. Innerspring Mattress

The innerspring mattress doesn’t mean a special kind of filling material. The filling can be anything such as coir, buckwheat, latex etc. Plus, a steel skeleton, in the form of coils or springs, is inserted to add extra support, firmness, and flexibility.

The springs squeeze and stretch with your baby’s movements providing support at every move.

An innerspring mattress is generally expensive than it’s foam based counterparts. But if the affordability is not the bar for you, I would suggest choosing an innerspring model.

To govern the firmness of an innerspring mattress number of turns or coils is considered as the main factor. The higher the number of turns the better it is. As a rule of thumb, a good standard size innerspring mattress should possess 200+ coils.

What Should You Do Now?

The answer is obvious. So far, you know the nitty-gritty that makes a safest crib mattress. Before choosing one for your tiny angle must cross-check the specifications with the recommendations in this article.

If your current mattress is not made up to the standard, it is wise replacing it immediately.

Used or New Mattress: Which One You Should Buy

Never Ever Think About Used Mattresses

Sorry for being a little harsh but it is a common scenario that the parents use the same mattress for their new-born that they used for the elder sibling. Over the time, it has lost its firmness and become lump that might affect the body structure of the infant.

The pie, litter, slavia of the elder baby, dust mites, liquid food seeps into the mattress that makes it infectious. A stored bedding starts releasing some odour and gases due to the foam degradation and chemical reactions.

Now think about it. I am deterring you from using the mattress that has been used by the elder sibling then how can you think of buying a mattress used by an unknown baby. Just discard the idea and choose a brand new product.
