Sealy Baby Firm Rest Crib Mattress Review

Are you on a Tight Budget? Then this is for you.

The Sealy Baby Firm Rest Crib Mattress was one of the best cheap crib mattresses I came across during my research for the best baby crib mattress for my child’s crib. Based on the praise I read in multiple crib mattress reviews, I discovered that the Sealy Baby Firm Rest Crib Mattress had won numerous awards for safety and healthy environment commendations. The more I learned about this mattress, the more I liked what it had to offer for myself and especially, my child.

Sealy Baby Firm Rest Crib Mattress


Sealy Baby Firm Rest Mattresses were designed to accommodate a baby with the highest levels of comfort and safety. The mattress is waterproof with a hospital-grade coating that repels liquids and doesn’t allow anything to penetrate the mattress material. The mattress materials are hypoallergenic, tightly stitched to prevent tears and splits in the seams, and is equipped with a pocket on the side for ventilation purposes to allow the mattress to breathe. The inside of the mattress is a system of heat-tempered coils that provide the best support and create a firmness that is recommended by medical experts for babies to sleep on.


The Sealy Baby Firm Rest Crib Mattress is designed to be kept for the first several years of your baby’s life. The mattress can be used throughout infancy and well into the toddler years. This saves parents from having to buy another mattress whenever their child moves into a toddler bed. I specifically set out to find such a mattress as a cost-saving measure with my own child. Waterproofing is another aspect that helps parents tremendously. Without this feature, there is no telling what would soak into the mattress. The fact that it is also easy to clean is just icing on the cake.

Meets Standards & Security

In regards to the health and safety of your child, the Sealy Baby Firm Rest Crib Mattress goes above and beyond the normal health and safety regulations to ensure that your child’s well-being is the top priority. The waterproofing on the mattress has a dual purpose. Not only does it make the mattress easy to clean, but also the material used is hospital grade and has anti-bacterial properties that prevent illness and disease from being housed in the mattress. This specific design has been lauded with multiple awards by consumer safety groups, as well as professional safety boards.


The Baby Firm Rest provides a firm, comfortable surface on which a baby can sleep. My child rested well on this mattress and continues to sleep like a champ in her toddler bed using this mattress. The mattress hasn’t sagged or warped even after years of use. Clean up from leaky diapers or baby powder explosions are a breeze, and she never seems to get too hot with this mattress, a problem I’ve witnessed with other brands.

The Good

  • Firm, but still comfortable
  • Waterproof surface
  • Antibacterial and hypoallergenic
  • Easy to clean
  • Well-made with quality materials
  • Cheap price in comparison to other similar mattresses

The Bad

  • The waterproof covering may not appeal to some parents who expect the mattress to have a soft, pillow-like top like their mattress
  • Some customers claim that the waterproof coating makes noise when the baby shifts around on it. This is not the same experience for everyone
  • Some customers claim an indentation forms in the mattress where the baby lays most often

Bottom Line

Sealy Baby Firm Rest mattress is one of the best crib mattresses that are under $100. I was impressed by the amount of forethought put into the design and I appreciated the fact that the mattress will last throughout the years my child will sleep in a diaper. I am immensely pleased that for a single purchase, I can get years of use out of this mattress. This is not the best crib mattress but certainly the best for the price you pay.
