Naturepedic Ultra 252 Seamless Dual Firmness Crib Mattress Review

The Best of the Best Organic Crib Mattress

When preparing to welcome a new baby, one of the most important decisions parents make is what their new baby will sleep in. Once a crib is chosen, all the pieces should fall into place, right? Perhaps not, because the next crucial choice is the mattress the baby will spend the majority of his her time on for the first few years of his or her life.

While researching and choosing a mattress for my baby, I found the best organic crib mattress on the market. Below is my review of the Naturepedic Ultra 252 Seamless Dual Firmness Crib Mattress.

Naturepedic Ultra 252 Seamless Dual Firmness Crib Mattress


The Naturepedic Crib Mattress is made with 252 tight coils, which creates a firm surface. It is made from 100% organic cotton, and is seamless, making it waterproof. Due to its organic material, the mattress is odorless, unlike mattresses that contain non-organic materials. It was refreshing having a mattress that didn’t require airing after purchase to rid it of the smell!

This organic crib mattress also comes with a unique feature. The mattress is dual-sided, meaning on one side is a firmer surface for infants and a softer side for toddlers. Each side is marked, so you won’t confuse which is which.


The mattress is seamless and easy to clean in the event of a mess. It is also designed to fit very snugly within a crib, so it is advisable that you measure your crib carefully. I was surprised by how tight the fit was, but I feel this is an advantage to the design. The tight fit makes it more difficult for blankets, pacifiers, toys, and other things to become wedged between the crib slats and the mattress.

Meets Standards

A new baby is a lot of work, and the last thing I wanted to worry about was the crib my child slept in. In addition to the mattress being organic and meeting numerous green living standards, it is also easy to clean, and, with the absence of seams, poses almost no risk of soaking up any liquids with can lead to bad smells or mildew.

The mattress is designed to be soft for the baby while remaining firm and steady. Since the Naturepedic is comfortable, the baby (and Mommy and Daddy) gets a peaceful rest.


There have been a few issues regarding the mattress size and fitting the mattress into an existing crib. We measured out our crib carefully and double-checked the dimensions of the Naturepedic mattress before we made a final decision about purchasing it. This saved us quite a headache. Some cribs are designed slightly smaller than standard crib sizes, making the fit nearly impossible. Always be sure you check the dimensions for items that are meant to go together before making a final purchase. This is especially true for anything bought online.

The Good

  • Made with 100% organic materials
  • Omits no odor
  • Dual sided so the mattress can be flipped when the child is older, making the mattress useful longer
  • Seamless design
  • Waterproof
  • Snug fit in a crib
  • Made in the United States

The Bad

  • Some buyers have complained that the mattress is heavy
  • Complaints that the mattress is too firm
  • Difficulty fitting the mattress in certain cribs or finding bedding that fits
  • The Naturepedic is more costly compared to other crib mattresses

Bottom Line

After thoughtfully weighing the pros and cons of the Naturepedic Organic Crib Mattress, I believe I made the right decision and chose the best crib mattress available for my newborn son. While reading crib mattress reviews, I concluded that the majority of negative aspects involved the perceptions of other buyers, and these issues were not necessarily representative of the mattress as a product. It is true that the price of the mattress is a bit costly, but, for a high-quality product, I expect to pay a little more.

Two characteristics made my decision much easier. The fact that the mattress is organic eased my mind from thoughts about placing my son in a crib that contained a mattress composed of various materials treated with nameless chemicals. The dual-sided component was a major plus for me. The mattress can be used far longer than a regular crib mattress, extending its life, and, in my opinion, making the extra money worth it.
