How to purchase the best mini crib mattresses?

The right size of the mini crib matters

Sizing is essential because small cribs need the same considerations. The mattress and the crib’s sides shouldn’t have broader spaces than two fingers. You’ll need to consider what will fit inside your small cot carefully. The FDA’s crib guidelines state that a mattress for a crib must fit snuggly against either side of the bed to allow your child to stay safely on top of the mattress.


The Crib mattresses are designed to keep babies safe, help reduce the risk of SIDS, and support their sleeping. Always keep in mind the firmness top when shopping for a crib mattress. It should not sink with the weight of your baby. When choosing a foam crib mattress, check it by pressing your hand firmly down on it. The faster it springs back up, the better.


The material of the small mattress is also big: the cover and the filling. The crib mattress you choose should be easy to clean. The cover should be waterproof and easily removable, and washable. Some crib mattresses are covered with vinyl, like PVC (polyvinyl chloride), containing phthalate that is used to make plastics more durable.

Organic, Breathable, and Design

All crib mattresses produced in the US must meet the same government safety criteria. There is plenty of certifications and titles in crib mattresses, from natural and organic to GREENGUARD Gold Certified and GOTS. If you’re looking at breathable crib mattresses, you should know there is no proof that they are safer than innerspring or foam alternatives or can prevent or lessen SIDS. 


When you are going to buy your mini crib mattress, consider its weight as an important factor. A lightweight mattress makes sheet changes both easier and faster. So take a lightweight mattress.


How thick of a mattress should a little crib have?

The same rules that apply to conventional crib mattresses do not apply to mini crib mattresses. Mattresses for standard-size cribs can be 6 inches thick, or mini crib mattresses are no more than 6 inches thick.

How long can a child remain in a little crib?

A baby cannot spend as much time in a small crib as in a regular crib. Once a baby weighs about 20 pounds, it often cannot remain in a mini crib long. If you get a flippable small crib mattress, keep that in mind since if your child is old enough to convert to the softer side, they might only stay in the mini crib for a short time.

Is a mini crib safe for newborns?

Newborns are thought to be safe in mini cribs. Your baby will sleep more securely at night if you provide a surface free of soft toys, additional blankets, and a firm and breathable mattress.


Choosing the ideal mini crib mattresses for the baby can be difficult due to the huge range of models, brands, materials, and thicknesses.
