Standard Crib Mattress Size

Last June, 20,000 Simmons mattresses were recalled as they did not meet the standard crib mattress size regulations more details. This was obviously a manufacturing error. It proves that we cannot always trust the manufacturer or sales associate to sell us a safe product.

Often times they are not even aware if there is a problem with their product until something happens. That’s why we must be diligent and always check ourselves. Just bring a measuring tape to the store or measure the mattress once it’s delivered if you buy it online. In the above case, the recalled Simmons mattress was less than 27.25 inches (69cm) wide, and a baby became trapped. This could have been avoided if the baby's parents just checked the width of the gap between the mattress and the crib rails.

If you are looking for a Simmons Crib Mattress that hasn't been recalled, I recommend the Simmons Kids Beautyrest Beginnings Nighttime Whimsy Luxury Firm Baby Crib and Toddler Mattress.

This standard crib mattress size fits inside a standard crib with its square corner design. Another great feature is that this mattress can be flipped for different size or age children. This is a unique product in that is a dual sided mattress. One side of the mattress is firm foam and provides a supportive sleep surface. The other side is made for toddlers with a thin layer of memory foam designed to provide a combination of comfort and support.

The mattress has over 200 coil springs, making it extra firm, strong and durable. It also has a Moisture Ban cover designed to repel moisture. In addition, the side air vents allow it to breath and keep baby's mattress smelling fresh. The AllerCare feature is designed to help reduce allergens in the mattress. This mattress also meets or exceeds all applicable safety standards.

I often recommend that it is always a good idea to read former buyer reviews. I found many of the comments from Amazon Reviews to be helpful. Many mentioned how they liked the choice to reverse the mattress as the baby grows into the toddler age. Several commented on the superior durability and value of the mattress. Overall, it seemed most liked the results that their children were sleeping well on this mattress.
