Best Mattress For Crib – Buyers Guide
We understand how difficult it is to shop for the ideal crib mattress for your infant, which is why we are going to share this buying guide to help you choose the perfect crib mattress. We’re going to be outlining different types of crib mattresses along with shopping considerations related to crib mattresses for infants.
Types of Materials Used in Mattresses
There’s an extensive range of options available in the market when it comes to crib mattresses for infants and here are the most common ones:
Foam mattresses are generally made from polyurethane foam and tend to weigh less than other crib mattresses while measuring around 4-to-6 inches thick.
The foam used in standard mattresses may range from very firm to very soft, but a lot of crib mattresses are rated as ‘medium-firm’ or higher. Firm mattresses are considered to be the safest choice for infants.
Support in any mattress is related to its density, which indicates the weight in pounds per cubic for the foam. Any foam that has higher densities will provide better support than lower-density foams.
Foam is linked to above-average off-gassing, but most crib mattresses are made from foam that produces minimal odor.
- Crib mattresses with foam layers offer no noise when bearing weight
- Foam mattresses tend to offer less edge support compared to innerspring
- Foam-based crib mattresses are the most affordable options
Innerspring mattresses have steel coils in the support core and they also feature at least one cushioning layer of cotton or foam, along with an insulator pad that acts like a buffer between the springs and the child’s body. Innerspring crib mattresses are also heavy, weighing around 15-to-20 pounds and are made from organic comfort layer materials that may weigh more.
Most innerspring mattresses are firm enough for infants and newborns and have minimal rollover risk.
Crib mattresses with springs provide targeted support based on the weight distribution of the child’s body, which is why they offer more support than foam-based mattresses.
Innerspring mattresses don’t produce any off-gassing, but models with foam layers may emit some kind of odor.
Some innerspring mattresses may be noisy due to squeaking coils
Innerspring crib mattresses are more expensive than foam crib mattresses, especially those with organic components
Innerspring crib mattresses are also heavier but do have above-average lifespans
Organic refers to any mattress that has been certified by the Global Organic Textile Standard (GOTS), and most organic mattresses are considered ‘foam’ models. However, you should note that organic mattresses are never 100% organic, and the GOTS certification is given to materials that are at least 70% organic, wool, cotton, or latex, and contains polyurethane foam, which is CertiPUR-US certified.
Organic crib mattresses are generally designed with single or dual-firmness surfaces, and at least one side is sufficiently firm for an infant.
The support of an organic mattress will vary from model to model, but with foam mattresses, it’s tied to foam density, along with mattress thickness.
- They are like standard foam mattresses in terms of producing less noise and offering below-average edge support
- Organic crib mattresses are common but aren’t as widely available as innerspring or standard foam models
- Organic crib mattresses are the most expensive models you’ll find in the market, with a price range of between $150 to $200
Things to Consider When Buying a Crib Mattress
There are several key factors that you must consider when you’re buying a crib mattress for infants, and we’ve highlighted the most important ones here.
Certification of Materials
Crib mattresses are generally certified in multiple areas since all models need to be GREENGUARD Gold-certified for minimal emissions of volatile organic compounds (VOCs). The Greenguard Gold certification applies to VOCs, along with any other chemical components that have a health risk. Apart from that, foam mattresses need to be CertiPUR-US certified, and this designation ensures that the foam doesn’t contain certain materials, like lead or formaldehyde. Crib mattresses that are sold as ‘organic’ must be Global Organic Textile Standard (GOTS) certified as well.
Most mattresses are known to emit distinct smells, which is known as off-gassing when they’re removed from their original packaging. These odors are unpleasant, and they usually dissipate after a couple of days if the room is well ventilated. Foam mattresses are known for producing more off-gassing than innerspring mattresses.
The price-point of a crib mattress varies depending on the type of mattress, but most models are priced lower than standard-sized mattresses. Foam crib mattresses are priced less than $100 and innerspring crib mattresses will cost you anywhere between $75 to $150. Crib mattresses made from organic or natural materials are more expensive and will be around the $300 to $400 price-point.
The cover material may also impact the price because vinyl covers are very expensive and considered to be easier to clean and more breathable than cloth covers.
Ease of Cleanliness
It’s no secret that accidents tend to happen from time to time, and a mattress with a washable cover and core is recommended in such instances. A multi-layered vinyl or polyethylene cover can help resist stains and leaks, and removable cloth covers can also be washed. A mattress that resists stains and is easy to clean can be great for parents and create a sanitary sleeping place for the infant.
Vinyl covers for crib mattresses may produce squeaking sounds whenever the child rolls around, and that can lead to sleep disruptions. In comparison, cloth covers are quieter and in the same vein, foam-based mattresses are quitter compared to spring-based mattresses.
Temperature Regulation and Breathability
The leading cause of SIDS is overheating, which is why parents must look for mattresses that help regulate body temperature. How breathable the materials of the mattress are is tied to temperature regulation, especially for covers. For instance, cloth covers retain more heat than vinyl covers, but the cloth is also more breathable even though vinyl covers are aerated or perforated so that they are more breathable.
A lot of crib mattresses don’t have reinforced support along the edges, which causes the edges to sink whenever a young child rolls over on their side. That leads to the risk of physical injury and suffocation and can also be dangerous for toddlers to stand on the edge of their crib. That’s the reason why most people check if the mattress fits snugly inside the crib, and the edges aren’t sinking deeply.
Heavy crib mattresses are harder to move for changing the sheets or cleaning, and most crib mattresses tend to weigh around 20 pounds. Foam mattresses are the lightest followed by innerspring mattresses.
Another mattress factor that increases the risk of SIDS is firmness because firmer mattresses are considered to be safer for infants. Softer mattresses conform to the body of the baby, increasing the likelihood of them sinking too deeply or rolling over on their side and suffocating. Soft mattresses are suitable for toddlers with more control over their movements, and a lot of mattresses today are sold with different firmness levels on each side of the mattress.
To decrease the risk of SIDS, babies must sleep on their backs as it’s easier to breathe in this position. Infants placed to sleep on their stomach are at a higher risk of suffocation, and a supportive mattress will help babies remain on their backs, while mattresses that don’t have sufficient support may lead to the child rolling onto their stomach.
The cover is the outermost layer of material on a mattress, and some crib mattresses come with waterproof covers made from polyurethane or vinyl, and are either single or multi-layer, and are ventilated to prevent a buildup of leakage when accidents occur.
Some covers are made from cloth fabrics like cotton, but they’re not waterproof, while covers with nylon layers provide more fluid resistance. Make sure that you check for certification labels on the cover, as some vinyl covers have plasticizers or phthalates, which are harmful to the health of the baby. A quality crib mattress should be free from phthalates.
The U.S. Consumer Product Safety Commission (CPSC) states that mattresses used in cribs must be at least 27 ¼ inches wide, 5 11/4 inches long, and not more than 6 inches thick. CPSC standards also call for mattresses that snugly fit inside the crib with little or no space on the sides so babies aren’t trapped.
Care Tips After Buying the Right Crib Mattress
With the right crib mattress, your baby can sleep well without worrying about inhaling chemicals or other common concerns parents have about crib mattresses. You’ll have peace of mind knowing that your baby is getting rest with the right firmness that they require for healthy bone development. Here are some of the tips for proper care of crib mattresses for the best sleep for your baby.
Rotate It Regularly
To avoid one side of the mattress sinking or wearing out before the other side, you need to rotate the sides regularly. This way you won’t have a sunken or lumpy mattress, which isn’t going to be comfortable or safe for your baby. It’s recommended to rotate every 2 weeks in the beginning and then follow the recommendations of the mattress manufacturer.
Clean It Regularly
You should vacuum the mattress regularly to remove any dust or dirt-buildup that isn’t properly visible. Scrub away any stains and rinse areas thoroughly, and don’t forget to disinfect the mattress regularly and leave it out to air it before placing your baby back on the mattress.
Wipe Away Messes Immediately
Accidents and spills pose a sanitary concern if they aren’t cleaned up immediately or properly. Some spills include harsh chemicals and harmful bacteria they don’t want your baby breathing in. Follow the care tips of the mattress manufacturer for wiping up stains without damaging the mattress. Remember to use a mattress pad or cover to catch stains and for an easy and quick clean up.
Air Out the Mattress
When your new crib mattress for infants arrives, you should air it out for at least 2 days before using it. Airing out the mattress is recommended because it reduces the common scent of a new mattress and any potentially harmful VOCs trapped in the mattress are also released.
Frequently Asked Questions – FAQs
Even though we’ve tried our best to explain everything about crib mattresses for infants, we understand that there are still going to be some questions that we haven’t answered. We will attempt to do that by highlighting some of the frequently asked questions by individuals, shopping for crib mattresses for their infants or toddlers. These were our top picks:
Do I need a crib mattress for my infant?
You need a crib mattress for the safety and health of your baby. Most parents use bassinets or sleep with their babies, but these aren’t the safest sleeping options for babies. Remember that babies require firm support when sleeping for a healthy spine, bone, and body development. So, when your baby grows into a toddler or reaches 35-inches, you’ll have a wider range of mattress options to choose from.
Can I use a second-hand crib mattress?
Buying a second-hand crib mattress is going to be cheaper, but it isn’t the safest option. That’s mainly because a second-hand crib mattress is going to have sanitary concerns like stains, or trapped mold or mildew. Also, over time a used mattress isn’t safe because of shrinkage or worn out springs. You should also remember that older crib mattresses may not fit the standard sized cribs in the market today.
How long does a crib mattress last?
On average, a crib mattress may last between 3 to 5 years depending on the proper use and condition of the mattress. The average lifespan of a crib mattress depends on whether it’s mold-resistant or waterproof. It also depends on the material of the mattress and regular maintenance like using a proper crib cover and cleaning stains.
What are the best crib mattresses to buy right now?
Look for crib mattresses that are certified and specially designed to keep the baby safe during sleep. Organic mattresses aren’t the best, but they do have better materials that help reduce allergy symptoms with environmentally-friendly and chemically sensitive materials.
Look for crib mattresses that are CertiPUR-US certified, which dictates that they have no lead, flame retardants, mercury, or other harmful ingredients. These mattresses are tested to be durable. You should also buy crib mattresses that are GREENGUARD Gold-certified since they meet the special requirements for fewer harmful chemicals and VOCs.
All parents will be familiar with the famous phrase ‘sleeping like a baby’, but that’s not always the case, especially when your baby starts growing into a toddler and moving around in the bed. If you’re lucky that your baby sleeps in their own crib, you want to be completely sure and confident that your baby is safe and comfortable in there. So, give yourself peace of mind and your baby a nice rest by buying a crib mattress for your infant today.
