What Is a Crib Mattress Pad?

A crib mattress pad is a sheet that you place on top of your baby's crib mattress to help keep him comfortable and safe at night. It's usually fitted with elastic around its edges to secure in place. It's placed under your baby's fitted sheet and provides an extra layer of padding and protection.

Why Use Organic Crib Mattress Pads?

There are many reasons why you should choose organic crib mattress pads for your baby. Here are just a few:

  • Organic cotton is naturally hypoallergenic and free of pesticides and harmful chemicals. Your baby does not need to suffer from allergic reactions or rashes caused by conventional mattress covers. If you choose organic materials for your infant's bedding, they will be safe from the harmful effects of harsh chemicals.
  • Organic bedding is good for the environment since it is free from harmful pesticides and chemical fertilizers. There are no petrochemicals or other chemical agents involved in the production process. Organic cotton plants require less energy to produce than non-organic ones because fewer chemical agents are used during manufacturing. A clean, safe environment is good for both baby and planet.
  • Organic mattress pads are not only healthy but are also durable. Natural fibers can withstand tough wear and tear better than synthetics. Organic cotton will keep its shape after repeated uses, which means you won't have to replace your baby's crib pad so often!
  • Organic cotton is also absorptive but at the same time breathable, which keeps your baby comfortable during the night. By allowing some vapor (e.g. perspiration) to vent out, your infant or toddler sleeps on a dry, comfortable sleeping surface.
  • An organic crib mattress pad can also feature a waterproof layer that protects the crib mattress from nighttime accidents and spills! The non-toxic waterproof barrier not only prevents liquids from reaching your baby’s mattress, but it also blocks dust mites and other allergens.

Organic crib mattress pads are also soft and comfortable because the fibers have not been exposed to harsh chemicals, which makes them even more comfortable for your baby!

What to Look for in a Crib Mattress Pad?

A good crib mattress pad will have a firm surface, a snug fit, and be waterproof. Also the pad shouldn’t make any noise when your baby moves around on it! A noisy mattress pad could wake your baby up. 

A pad with a thin and firm surface will prevent suffocation and the waterproof lining will prevent bedwetting, spit-up or other fluids from leaking through. Your crib mattress pad should also be made from non toxic materials that meet safety standards. This will ensure that your baby sleeps in a safe environment.

Materials to Avoid in a Crib Mattress Pad:

If you want to buy a safe non toxic mattress pad for your baby, beware of the following materials:

  • Vinyl/PVC: Vinyl is commonly used in waterproof crib mattress covers but it's made of PVC (polyvinyl chloride) plastic that has been found to be a human carcinogen. On top of that, it's often softened with phthalates which have links to reproductive harm as well as asthma amongst other things!
  • PEVA/EVA: These types of vinyl do not contain any chlorine, yet they still may have some chemicals present which might have a damaging effect on your health.
  • Polyurethane: In some cases, this material should be avoided because it can off-gas harmful chemicals. However, organic mattress pads use Greenguard GOLD certified polyurethane waterproof backing that is considered safe for your baby.

Can I Use a Crib Mattress Topper Instead of a Crib Mattress Pad?

No, you should never use a crib mattress topper as a substitute for a crib mattress pad. A mattress topper is used on top of an existing mattress and not as a replacement cover. 

A mattress topper is used to make a current mattress more comfortable while a crib mattress protector is a waterproof barrier that protects the mattress from accidents or spills.

Do I Still Need a Mattress Pad for a Waterproof Crib Mattress?

Even if your baby's mattress is waterproof, it's still covered with a fabric that can become worn and stained over time. This damage can be prevented by placing a crib mattress cover between your baby and the mattress itself.

Do I Need a Crib Mattress Pad?

A crib mattress pad will protect your child's mattress. It prevents the mattress from getting wet and dirty with all those spills and diaper leaks, with its waterproof surface. This will ensure that you won't need to continually buy new baby mattresses as time goes by.

Will a Crib Mattress Pad Make the Crib Mattress Softer?

If you are concerned about your baby's mattress being too firm, add a thin padded crib mattress pad or another type of mattress protector for additional comfort and softness.

However, it is not recommended to add any extra padding that will make the mattress much softer, it's better to have a firm mattress for baby's safety. Firm crib mattresses are safer for babies because they help prevent SIDS and suffocation.

Do I Need an Organic Crib Mattress If I'm Using an Organic Mattress Pad?

Conventional crib mattresses made of foam and polyurethane are treated with flame retardants, stain repellents, and other chemicals. Thus it's a good idea to cover your conventional crib mattress with a safer organic mattress pad to prevent contact between baby's skin and these chemicals.

However, many parents wonder why they should invest in an organic crib mattress if the top of the mattress is covered by a mattress pad.

The problem with synthetic mattresses is off-gassing. Off-gassing is caused by volatile organic chemicals (VOCs) evaporating from the mattress. These VOCs are well known to cause allergies and other health problems.

However, it is very difficult to reduce VOC emissions because foam mattresses are composed of synthetic materials that continuously out-gas harmful chemicals. Dyes, flame retardants, stain repellents, and adhesives all contain VOCs.

That's why it's best to invest in a good-quality organic crib mattress. This way you can rest assured that your baby isn't exposed to the harmful chemicals coming from conventional crib mattresses.

How Many Mattress Protectors Do I Need for a Crib?

There is no specific number of mattress protectors needed for a crib. However, you should have at least 2 just to be safe. Why? If one mattress protector gets dirty or soiled you'll still have another one to use while the other is being washed.

Frankly, it's always better to have more than 2 crib mattress protectors just in case. You don't want to run out every time you need to wash one.

The important thing is that you start off with two and see how it goes from there. If you need more, then get as many as you think you'll need.
