​The advantages of baby mattress

It can be difficult to find the best crib mattress due to the abundance of options on the market, but you can’t go wrong with a mattress that allows air to circulate. The following are some of the reasons why it is so enjoyable for babies and their parents:

​1. It reduces sweating

Most standard mattresses have a dense construction, which traps heat and leads to an excessive amount of sweating; this is not a good situation for kids. A crib with a mattress that allows air to circulate will prevent this problem from occurring. You won’t have to worry about your child getting too hot while he or she sleeps for the recommended 17 hours.

2. It keeps mold and bacteria at bay

The perforations prevent the buildup of moisture on the surface, which in turn reduces the prevalence of bed mites, germs, and molds. It addresses one of the main issues with modern mattresses by preventing moisture buildup on the surface and even inside. Because mold and bacteria are prevented from growing, a wide range of illnesses and infections can be avoided.

3. Reduced risk of Suffocation

Because the material is perforated to let air circulate freely, your baby will never run out of oxygen while sleeping, no matter how he or she is sleeping. Whether your baby is sleeping with their face up or down, you need not worry about their safety because air can easily pass through the mattress.

4. You’ll get your sleep as well

This mattress eliminates the need to wake a sleeping baby by flipping him or her onto his or her back from a tummy sleep position. You can get some shut-eye without worrying that your infant is in a position that could lead to sudden infant death syndrome, and vice versa.

5. Alleviates the need for bed sheets

A mattress that allows air to circulate is designed to be used without the addition of bed sheets, as the surface is already comfortable. The perforated design of the material makes cleanup a breeze, and it dries quickly after washing. While sheets can be used, it’s important to remember that doing so may reduce the aeration quality of the material and increase the risk of suffocation. Therefore, it should be used without any modifications to ensure the safety of your infant while they sleep.

6. The green aspect

An organic crib mattress is a great eco-friendly option that contributes to the fight to save our planet from the pollution that has taken over our world.

How Big A Baby Mattress Is

Your infant will be spending a lot of time on the mattress, so make sure it’s a good one. It’s important to know how big a baby mattress should be.

Here are the two most common varieties of infant mattresses on the market today.

Standard size

Baby mattresses typically come in this standard size.

The maximum thickness for the mattress is 6 inches.

It’s 52 inches in length and 28 inches across.

These mattresses work great for cribs that are the typical size.

Here is the best resource I’ve found for learning about infant crib sizes.

Mini size

Baby mattresses are typically smaller in size than adult mattresses.

Common dimensions are 24 inches in width and 38 inches in length.

The comfort of your beautiful baby during sleep can be affected by the mattress depth you choose.

What Are The Things To Remember In Choosing A Baby Mattress?

There are a few things to keep in mind when shopping for a baby mattress, provided you have the right dimensions.

#1. Safety

Baby safety comes first, which is why the law restricts the dimensions of baby mattresses.

Its purpose is to keep babies from suffocating or having their heads get stuck between the crib and the mattress.

Keep in mind that the mattress you already have fits perfectly inside the crib.

Unless it is a designated crib mattress, using it with care will help.

Foam toppers and other unregulated mattress protectors should be avoided for use on infant crib mattresses.

Your baby will be safer this way.

#2. Firmness

Babies should sleep on firmer mattresses rather than soft ones. Babies should not sleep on soft surfaces because of the risk of suffocation.

Diseases like Sudden Infant Death Syndrome (SIDS) may be more likely to develop as a result.

Pressing on the mattress’s center and edges is a good way to gauge how firm it is.

The mattress should snap back quickly after the force is removed.

#3. Non-toxic

Keep in mind that your baby will most likely spend the first few years of their life on the mattress.

Choosing a natural or organic mattress may help. Check for GOTS certification, which stands for the Global Organic Textile Standard.

Therefore, it is suggested that they have a healthy and secure environment.

Furthermore, GOLS (Global Organic Latex Standard) certification is an option.

#4. Weight and depth

The depth of some mattresses is irrelevant to the level of firmness they provide.

The depth of a foam mattress is typically between 4 and 6 inches, while a mattress with coil springs is 5 to 6 inches deep.

Foam mattresses, with the exception of memory foam mattresses, tend to be on the lighter side.

#5. Length of use

There aren’t a lot of mattresses that can be flipped over to have a softer side for a baby and a firmer side for a toddler.

Double-sided mattresses, also known as two-stage mattresses, clearly indicate which side should be used.

#6. Cost

A high-quality crib mattress can be purchased for $90-$200.

Organic and hypoallergenic options may cost more, but they are worth considering.

#7. Covers

The surface of most infant mattresses is protected by a cover to prevent damage from diaper leaks and other accidents.

Choose the more secure water-proof, breathable, and hypoallergenic options if you want a good, dependable cover.

Covers with plastic seams should be avoided due to the potential for injury. Also, check the seams to see if the fabric has been stretched or strained.

To My Parents, You should buy two mattress protectors in case your baby has an accident in the crib.

#8. Buy new

Baby mattresses that have been soiled, mistreated, or are old should be avoided at all costs.

An old mattress may harbor molds, which can be harmful to your baby’s health.

You should upgrade to newer models to avoid these dangers.

#9. Consider border rods

Innerspring baby mattresses should have border rods to prevent the mattress from sagging.

They usually wrap all the way around the upper and lower edges of the bed.

Stronger firmness, durability, and support can all be gained from using border rods.

What to Look For in a Crib Mattress

Size

It would be unfortunate to order a mattress for your child’s crib only to find out that it does not fit. The typical dimensions of a crib are 28 by 52 inches. There should be no space between the mattress and the crib’s walls. According to registered nurse Lindsay Albutt, this prevents your infant from becoming wedged between the mattress and the side of the crib. She explains that the American Academy of Pediatrics agrees with these suggestions: “These are all recommendations supported by the AAP.

A standard crib mattress will not fit in a mini or portable crib. Mini crib mattresses should fit inside a space measuring no more than 24 by 38 inches. This is the first step in creating a cozy and secure nursery for your newborn.

Material

Foam, cotton, wool, and polyester are just some of the materials used to make crib mattresses. It’s not just the material itself, but how it’s put together, that matters. Make sure the crib you buy is made from non-toxic, chemical-free materials to protect your child’s health while they sleep. When you go shopping, keep an eye out for labels that say things like “organic,” “non-toxic,” and “hypoallergenic.” This ensures that your child’s mattress will not cause any allergic reactions.

The temperature you feel while sleeping may also be influenced by the mattress’s material. If your infant tends to get hot easily, you may want to invest in a special mattress designed to keep them cool.

Firmness

Albutt explains how you can help prevent SIDS by putting your baby to sleep on their back on a flat, firm surface. Her findings suggest that unsafe sleeping conditions account for 72 percent of the annual 3,400 SUDI deaths. Taking even simple precautions to ensure your child’s safety at night is crucial.

Mommywise creator Natalie Nevares says, “Firmness ensures that when babies inevitably roll over, they won’t suffocate.” This does not mean that comfort must be sacrificed. She goes on to say, “If I wouldn’t want to sleep on the mattress, I don’t want my baby sleeping on it.”

Breathability

Nevares states that when looking for a crib mattress, breathability and firmness are her top priorities. Most mattresses are designed to allow airflow even if flipped onto their stomach, so you can rest assured your baby will be able to breathe while they sleep. Although some fabrics are inherently more breathable than others, it’s always preferable to choose a product that advertises itself as lightweight and breathable.

According to Elizabeth King, CEO and founder of Sleep Baby Consulting, “avoid anything with pillow tops or comfort tops as they can lead to a sleeping area that is too soft.” “Baby’s face can get trapped in these squishy places, which can make it hard for them to breathe,” she says.

Sustainability

Crib mattresses aren’t always essential for baby safety or comfort, but they can be a selling point if they’re made with eco-friendly materials and follow sustainable production methods. You should look for a firm, Greenguard Gold Certified mattress when shopping for a crib for your child. Certified sleep consultant Kaley Medina explains that purchasing a mattress with this label means that you can rest assured that it has minimal chemical emissions within. In other words, these materials are both baby- and planet-friendly.

Waterproof

Waterproof crib mattresses can be quickly cleaned after an accident by being wiped down or put in the washing machine. Some of the items on this list have waterproof covers that are permanently attached and stitched together. Some have parts that can be taken off and washed, replaced, and reused. Waterproof covers can be added to any of the items on this list to make maintenance a breeze.

Keep in mind that waterproof coverings frequently make a lot of noise or crinkle. The plastic or vinyl they’re usually made of means they might not be the most pleasant thing to sleep on. If a waterproof cover isn’t built into the mattress, it’s a good idea to do some research before making a purchase. A mattress’s organic, non-toxic claims may not extend to the mattress’s waterproof cover, even if the brand makes those claims. Having gone to the trouble of finding a non-toxic, organic, allergen-free mattress, the last thing you want to do is cover it with something that isn’t as clean or safe.

FAQs

How do you clean a crib mattress?

Most crib mattresses are antimicrobial. Most of the items on this list can be cleaned quickly and easily by tossing them in the washing machine once a week or after any accidents. There are also options with waterproof covers that can be easily wiped clean to prevent liquid from seeping through. Before you dive in, it’s a good idea to familiarize yourself with the cleaning procedures.

Do crib mattresses make a difference in a child’s sleep?

Both Medina and Navares agree that your child’s sleep is not primarily affected by the quality of the crib and mattress. However, a great first step is to make your baby’s environment safe and pleasant. Teaching your child to fall asleep without the aid of sleep associations or sleep props is, according to Medina, the single most important thing you can do to get your child sleeping well. Making sure your baby is secure and comfortable in his or her crib will help your child adjust to sleeping there.

‘Sleep and development go hand in hand,’ Nevares explains. Once they begin getting sufficient, high-quality sleep, they will experience a dramatic increase in growth. Finding the right mattress for your baby, or anything else you can do to improve his or her sleep, will help your child grow and develop.

What do babies need to sleep?

A good, flat mattress and a fitted sheet are necessities for a baby’s crib. If the baby rolls onto their stomach, the sheet needs to be as snug as possible on the mattress to keep them from suffocating. For the safest sleep, Medina recommends having only the mattress and the fitted sheet in your baby’s crib, and nothing else (including mobiles, blankets, stuffed animals, toys, bumpers, etc.). Since a baby only needs a few things to fall asleep, it’s crucial that what they do have be of the highest possible quality and safety.

The Bottom Line

Great! A crib mattress’ dimensions have just been revealed.

Mini and standard are the two most common sizes.

Sizes range from 24 to 34 inches in length for the smaller ones, to 28 and 52 inches for the larger ones.

If you’re in the market for a new mattress, it’s a good idea to give some additional thought to the following considerations.
