To purchase the best crib mattress, look for:

  • firmness. According to the American Academy of Pediatrics, a firm mattress is suitable for infants, while toddlers may prefer a medium-firm surface
  • a good fit for the crib, so it is not possible to insert more than 2 fingers between the mattress and the frame
  • certification by independent 3rd parties regarding safety and non-toxicity of materials
  • a company with a good reputation and positive online reviews from multiple sources
  • new rather than used products, to avoid potential hazards of wear and tear

Getting enough good quality sleep plays a vital part in ensuring infant health and well-being. It is typical for a newborn to sleep for 14–17 hours per day and for an infant to sleep for 12–15 hours per day.

The American Academy of Pediatrics (AAP) recommends a crib with a firm mattress as a safe sleep environment for infants.

Putting an infant to sleep on their back can reduce the risk of sudden infant death syndrome (SIDS). The use of a crib and crib mattress can provide a flat and immovable surface that can further reduce the likelihood of SIDS and suffocation.

The AAP provides the following recommendations for crib mattress safety:

  • A crib mattress should be firm and fit the crib properly, leaving no gaps at the side.
  • Cover the crib mattress with a fitted sheet that is suitable for the mattress.
  • Any mattress toppers or sheets should fit tightly on the mattress so that they do not move, bunch up, or create gaps during sleep. They should never cover the infant.
  • People should not try to use alternatives to a crib mattress, such as cushions or pillows. Also, do not use these in addition to a crib mattress.
  • Do not use damaged or worn crib mattresses that may change shape during sleep.

The AAP also states that commercial products that claim to prevent SIDS may not offer any actual benefits.

The following are common questions and answers about crib mattresses:

How should a person choose a crib mattress?

People should consider the size of the crib and choose a mattress that fits it properly, with no gaps.

They may also wish to choose a mattress from a reputable brand. Looking for customer reviews from multiple online sources can help identify reliable brands and products.

Some companies also have third-party certifications, such as CertiPUR-US certification, which identifies products free from harmful chemicals. These certifications can help with identifying safe and high-quality products.

Is it better to buy new or used crib mattresses?

While used crib mattresses are often low-cost and a more eco-friendly option, they are not as safe as a new crib mattress. They may have wear and tear that can pose choking or suffocation hazards. Bacteria and mold may also be present but undetectable in these products.

With this in mind, it is best to buy a new crib mattress when possible to ensure it is clean and safe.

What can people do with old crib mattresses?

It is possible to recycle used mattresses at specified locations or with certain providers.
