Safe, comfortable sleep for your baby — certified and tested. We evaluated the best crib mattresses under $150 for firmness, breathability, and safety certifications.
Best overall — safe, affordable, and versatile
The Graco Premium Foam is the best all-around crib mattress at any price point. It's dual-sided with a firm infant side and a slightly softer toddler side, so it grows with your child. GREENGUARD Gold certified for low emissions, waterproof cover for easy cleaning, and lightweight foam core makes sheet changes effortless. Fits all standard cribs.
Best value — top safety ratings at the lowest price
At just $70, the Delta Children Embrace delivers GREENGUARD Gold certification, certified PUR foam, and a waterproof stain-resistant cover — the same safety features as mattresses costing twice as much. The 6-inch profile fits snugly in standard cribs, and Delta Children's reputation for baby safety is well-established.
Best innerspring option for durability and airflow
If you prefer innerspring over foam, the Safety 1st Peaceful Lullaby combines coils with a foam top layer for the best of both worlds. The breathable airflow border keeps air circulating, the waterproof cover wipes clean in seconds, and the 10-year warranty is the longest in our lineup. GREENGUARD Gold certified.
Best breathable mattress for peace of mind
The Newton Baby is the only fully breathable crib mattress — its Wovenaire core allows air to flow through the entire mattress, reducing suffocation risk. The cover is fully washable (toss it in the washing machine), and there's no vinyl, glue, or harmful chemicals. Dual-firmness means it works from newborn through toddlerhood.
Crib mattresses should be very firm — significantly firmer than adult mattresses. The AAP recommends firm mattresses to reduce SIDS risk. If the mattress leaves a lasting indent when you press on it, it's too soft. All mattresses in this guide meet federal firmness standards for infant sleep.
Both are equally safe when certified. Foam mattresses are lighter (easier to change sheets) and usually cheaper. Innerspring mattresses are more durable and tend to hold their shape longer, making them better for toddler use. If you plan to use the mattress for 3+ years, innerspring is worth the upgrade.
GREENGUARD Gold certification is the gold standard — it means the mattress has been tested for low chemical emissions. Also look for: JPMA certification, CPSIA compliance, and compliance with 16 CFR Part 1633 (federal flammability standard). All mattresses in this guide meet these standards.
Most children transition between 18 months and 3 years. If your child is climbing out of the crib, it's time. Many crib mattresses in this guide are dual-firmness (firm side for infants, slightly softer for toddlers) and work on both crib and toddler bed frames.
