Let me help you pick the right one.

Make Way for Mini Crib Mattresses

When it comes to buying a mini crib mattress, parents have their work cut out for them. Choosing the right crib mattress for your little one can be a little confusing. That’s why I’ve put together this short buyer’s guide to help you pick the right one. In it I’ll explain what a mini crib mattress is, why it’s important, and how to go about selecting the right option for your needs. I’ll also be answering all of your mini crib mattress buying questions.

What is a Mini Crib Mattress?

When buying a baby crib, parents are faced with two options; a standard or mini crib. As you’ve probably gathered the difference lies in the size. Naturally, a mini crib is much smaller than a standard one. As such you’ll need a mattress specifically designed for a mini and portable crib — a mini crib mattress.

How to Pick the Perfect Mattress for Your Mini Crib

Simply because you’re buying a smaller mattress for your baby’s crib doesn’t mean you have to compromise on factors such as quality and comfort. It’s your responsibility to create a safe and comfortable sleeping environment for your baby. So let’s discuss what factors you need to prioritize in order to pick the perfect mattress for your baby’s mini crib.

Fit

The mattress should fit perfectly in the crib — leaving no spaces around the edges. You don’t want your little one’s fingers or toes getting stuck in the gaps. When placed inside the crib, you shouldn’t be able to fit more than one finger between the mattress and the frame. This is probably a good place to mention compatibility. Some mattresses are only compatible with specific cribs while others are more versatile. Always pay attention to that fact.

Firmness

Consider the firmness of the mattress in relation to your baby’s age. Infants need firm mattresses that can support their fragile bones as they grow. A toddler’s mattress doesn’t have to be very firm. How do you establish the firmness? Press your hand down onto the mattress. It should regain its shape fast. If you find it easy to sink your hand into the mattress, it means it’s not very firm.  While it may be ideal for toddlers, the only trade off is it’ll sag sooner rather than later. So try and strike a balance between the two extremes for your older kids.

Support

As your baby grows older and puts on more weight, the mattress may start to sag making it uncomfortable for your little one. Some manufacturers counter this by incorporating a steel edge support design in the mattress and comfort cushioning. Picking such a mattress is in your baby’s best interests where comfort is concerned.

Waterproof

There’ll be a lot of wetness going on in that crib especially during the challenging potty training years. You want to make sure that you pick a mattress that’s waterproof and designed to resist mold formation. Pick one with a waterproof cover.

Materials

Is the mattress made up of organic or non-organic materials? If you prefer mattresses free from chemicals then pick one made up of natural materials. Mattresses made up of chemical ingredients tend to give off an unpleasant chemical smell especially soon after purchase. With any luck, it should disappear after a few days. But certain materials like polyurethane don’t stop off-gassing so keep that in mind.

Type

Most of the factors stated above are determined by the type of mattress you buy. Know that there are different types of crib mattresses that are classified according to their construction. The construction ultimately determines the comfort, price, durability, and firmness of the overall mattress. Basically all the factors you need to consider when picking a mattress. Here are the common types:

  • Spring Mattress: This type is more of the traditional kind and features spring coils inside making it more resilient and sturdy. And no, the coils won’t be poking at your precious bubba while they sleep. Multiple layers of cushioning materials are placed over the coils to create a comfortable sleeping surface. In fact, such a mattress will offer your baby better support while he or she sleeps. The trade off is that these mattresses are a little heavier and certainly don’t come cheap. If you’re unlucky the coils might be a little noisy when your baby changes sleeping position.
  • Foam Mattress: If you prefer something lighter and cheaper, then opt for a foam mattress. This type is made of lightweight materials such as cotton and foam resin. What you need to consider is if the mattress is resilient. This is because foam mattresses aren’t nearly as durable as spring mattresses. However, the chances of a foam mattress lasting longer are higher if you pick one that’s denser and firmer.
  • Double-sided Mattress: Consider this option if you want value for your money. This type will grow with your child and is designed with your baby’s comfort in mind. It has a firm side which you can use during your baby’s younger years. Flip it over to the softer side when your little one grows older. This type is the most expensive of the three, but as I’m sure you’ll agree, it makes for a long-term investment.

Mini Crib Mattress Questions and Answers

I’ll round off this buyer’s guide section by answering a few burning questions you may have when it comes to crib mattresses.

Is it okay to buy a second hand mattress?

I’d strongly advise against it. Old mattresses may have mold and bacteria which is a huge health and hygiene concern for your little one.

Can I decorate my baby’s crib?

Placing fluffy pillows and teddy bears in your baby’s crib might look cute and cozy. But these items can be a real suffocation hazard for your child. So, rather not.

When is the right time to flip a double-sided mattress?

Check the manufacturer’s instructions for the right time to switch the mattress to the softer side. Alternatively, you can check with your child’s pediatrician. But most parents do so around the one year mark.

Which position should my little one sleep in?

Always make sure that your little one is lying on their back. This can help prevent the risk of SIDS which is a common risk in a baby’s first year of life.
