What to Look for in a Crib Mattress
Firmness — a safety requirement, not a preference
The AAP recommends a firm, flat sleep surface for infants. A crib mattress should not indent significantly when you press on it with your hand. If it does, it is too soft for safe infant sleep. All five mattresses on our list meet the CPSC firmness recommendations for infant sleep.
GREENGUARD Gold certification
GREENGUARD Gold is the most important safety certification for crib mattresses. It screens products for over 15,000 chemicals and VOCs — ensuring the mattress meets strict indoor air quality standards. A baby sleeping 16 hours a day on a mattress will breathe in whatever the mattress off-gasses. GREENGUARD Gold certification provides meaningful assurance that off-gassing is minimal.
Fiberglass-free
Some cheaper crib mattresses use fiberglass as a flame barrier. When the cover is damaged or washed with abrasive cleaners, fiberglass fibers can escape and contaminate bedding and clothing — requiring professional remediation in serious cases. Always verify a mattress is fiberglass-free before purchasing. All five mattresses on our list are confirmed fiberglass-free.
Dual-sided design
Dual-sided crib mattresses have a firmer infant side and a softer toddler side — providing appropriate support for each developmental stage. The firm infant side supports safe sleep; the slightly softer toddler side is more comfortable for children who sleep in various positions. Look for clearly labeled sides.
Cover washability
Crib mattress covers will get dirty. A machine-washable, waterproof cover is a practical essential. The Newton is unique in that the entire mattress — cover and core — is washable. All other mattresses on our list have machine-washable covers. The waterproof surface prevents liquids from reaching the mattress core.
Frequently Asked Questions
How firm should a crib mattress be?
A crib mattress should be firm enough that it does not indent significantly when you press on it with your open hand. The AAP specifies a firm, flat sleep surface as a key safe sleep requirement. When you remove your hand, the mattress surface should quickly return to flat. A mattress that conforms around your hand is too soft for safe infant sleep.
How long does a crib mattress last?
Most manufacturers recommend replacing a crib mattress every 3-5 years for hygiene reasons, or before a second child. The Newton’s Wovenaire core carries a limited lifetime warranty — structurally it lasts much longer — but the mattress cover may need replacement before the core. Never use a second-hand crib mattress if you cannot verify its history and condition.
Do I need a waterproof crib mattress?
A waterproof surface on the mattress cover is highly recommended — it prevents diaper leaks and other accidents from penetrating the mattress core, which cannot be cleaned once saturated. All five mattresses on our list have waterproof covers. The Newton Waterproof also adds waterproof protection through the toddler years specifically.
