It's a relief when you finally settle on which crib you want for your baby. You've completed a key shopping task for your newborn. You've probably reviewed functionality, budget and, of course, a cute design.
At this point, you also know that another crucial decision is the crib mattress. It is the most important factor for your baby's sleep safety, and thus for your own peaceful sleep.
The problem with choosing a mattress after finding your favorite crib is that not all mattresses measure the same. There are standards in the USA, given by the CPSC, but they indicate a range of measurements and non-identical sizes. And then there are producers, like Ikea, who apply standards from other countries. The result: a lot of crib mattresses of varying sizes.
If you don't do your research, you may end up with a nice crib but a mattress that doesn't fit snugly. Maybe it’s too big, in which case it’s useless. But the worst-case scenario is that the mattress is too small. This is worse because it can become a risk to the safety of your little one.
Why is it unsafe if the mattress is too small for the crib?
Have you heard other parents talk about the "two-finger rule"? It's a simple way to remember the main safety rule when choosing a crib mattress: The mattress should not leave more than 2 fingers of space at the edges of the crib. A gap larger than this can become a trap for the baby and increases the risk of suffocation, or SIDS. (I suggest you read our comprehensive article on safe sleep for details).
So, for the safety of your newborn the mattress must fit perfectly in the crib, and since mattresses come in different sizes, and cribs too, then you have the “crib mattress size” puzzle to solve. Don't worry, because here we'll give you the solution to the “crib mattress size” puzzle.
If the heart of your nursery is an Ikea crib, you can jump right to the specific article we wrote about the best mattresses for Ikea cribs.
Buy a mattress of the same brand as the crib: Is this easy solution the best one?
Is your baby's crib a Pottery Barn Kids, Ikea, Babyletto or Davinci? All these favorite brands offer you their mattresses. But this is not the only option you have, and it is often not the very best. Below are five reasons why many parents have purchased other brand mattresses to improve their children's beds:
1. Variety: All these brands of cribs offer you only two or three mattresses of their own. On the other hand, in the mattress market, you will find a huge variety. You can find mattresses for all tastes and budgets. Breathable mattresses, organic or eco-friendly, with technology to increase freshness, waterproof, double-sided for newborns and for toddlers, in short, all the qualities we might look for in a premium mattress.
2. Expert brands: the crib you chose is made by furniture experts. But these companies are not experts in mattresses, let alone crib mattresses. Mattress experts meet standards, invest in research and development, and compete with each other to help your baby sleep better on their mattresses. The quality of mattresses you find in the top brands in this field is greater than the quality offered by furniture manufacturers.
3. Quality/price ratio: Buying a mattress other than the crib’s brand saves parents money by avoiding upselling. The crib stores sell you a mattress that can be found cheaper or of better quality if you look in the wide market offer. We have proved this in the research we did for this article.
4. Safety Risks: Some brands of affordable cribs offer cheap mattresses, $50 or less, that are of poor quality, often sag, release toxic vapors or simply quickly become useless.
5. The Easy Way ... is not always the best, and this is even more valid when the well-being of your baby is at stake. The convenience of purchasing in a single store should not be the primary criterion in this case. With this article, we aim to help you save time on research and come to a wise decision on the best mattress for your crib, whether it be Pottery Barn, Ikea, Babyletto or Davinci.
