How to Pick a Crib Mattress: Top Considerations

Choosing a crib mattress can indeed seem like a formidable task. But once you have an understanding of the core components, the puzzle starts to come together. Let's dissect the key points you should keep in mind.

Safety First

  • Regulations: The first and most crucial aspect to consider is safety. The mattress you choose must adhere to safety standards set by the American Academy of Pediatrics (AAP) and the Consumer Product Safety Commission (CPSC).
  • No Second Hands: Buying a used mattress might save money, but it's not advised due to potential hygiene and safety issues.


  • No Softies: A firm mattress isn't just a choice, it's a mandate. A soft mattress might seem cozier but it increases the risk of SIDS (Sudden Infant Death Syndrome). So, err on the side of firmness.
  • Firmness Test: Press the mattress in the center and at the edges. It should snap back quickly and not conform to the shape of your hand.


  • Foam: Generally lighter and easier to maneuver when changing sheets.
  • Innerspring: Heavier, generally more durable, and often more expensive.
  • Organic: These mattresses don't contain the chemicals found in foam and innerspring options, but can be pricier.

What to Look for in a Crib Mattress

Besides the big, overarching factors like safety and material, you have to delve into the finer details.

Mattress Cover

  • Waterproofing: Look for a water-resistant or waterproof cover to deal with spills, diaper leaks, and other baby messes.
  • Material: Cotton, vinyl, and polyethylene are common materials used. Choose one that aligns with your comfort and hygiene standards.


  • Vent Holes: Good airflow is a must. A mattress should have venting holes on the sides to allow air to flow in and out. This not only keeps the mattress fresh but also reduces the risk of suffocation.
  • Breathable Fabrics: Some modern mattresses also feature special breathable fabrics as an added layer of safety.

Flat and Even Surface

  • Smooth Surface: The mattress surface should be devoid of any indentations, lumps, or sagging. This is crucial for the safety of your baby.

How Long Does a Crib Mattress Last?

It's essential to understand that a crib mattress is not an eternal product.

Typical Lifespan

  • Foam Mattresses: 5-8 years. Beyond this, they begin to lose their form.
  • Innerspring Mattresses: 8-10 years. However, these mattresses are more likely to sag over time.

Signs of Wear

  • Visible Sagging: If the mattress sags visibly in the middle or on the sides, it's a red flag.
  • Tears and Holes: Any form of physical damage is an immediate signal to replace the mattress.

Baby's Growth

  • Adaptability: As your baby grows, their mattress may need to change to provide adequate support and safety.

Types of Crib Mattresses: Foam, Innerspring, and More

The variety is plentiful, but each has its pros and cons.

Foam Mattresses

  • Pros: Lightweight, easy to maneuver
  • Cons: May lack long-term firmness

Innerspring Mattresses

  • Pros: Generally firmer and more durable
  • Cons: Heavier and usually more expensive

Organic Mattresses

  • Pros: Made from natural materials, no harsh chemicals
  • Cons: Expensive and not always as durable

How Much Should You Spend?

Finally, the money talk. It's a subject that’s often skirted around, but let's face it head-on.

Price Range

  • Budget Options: Crib mattresses can start as low as $50. However, they may lack the durability and safety features you'd want.
  • High-End Choices: On the other end, you've got mattresses that climb into the hundreds. While more expensive doesn't always mean better, you often get additional features like dual-sidedness or organic materials.

Value for Money

  • Don't Skimp: It might be tempting to go for the cheapest option, but remember that you're investing in your child's safety. Choose a mattress that offers good value for the price rather than simply opting for the most economical one.


  • Check for Warranties: A mattress with a warranty provides a certain level of assurance and can be a deciding factor in justifying a higher price.
