Consider also how often you will need to lift it for changing its fitted sheet – lighter mattresses make this task simpler!

Size

Crib mattresses are specially-made mattresses designed for infants and young children that meet stringent safety standards in order to reduce the risk of Sudden Infant Death Syndrome (SIDS). Firmer than regular mattresses, crib mattresses help keep babies safe from suffocation while being available in different sizes to suit different needs; mini crib mattresses commonly known as bassinets fit perfectly into portable cribs or cradles.

Size is one of the key considerations when purchasing a crib mattress for your baby. Standard crib mattresses must fit securely inside the crib to prevent your child from becoming trapped between it and its rails; dimensions for such mattresses are set forth by the United States Consumer Product Safety Commission but there may still be slight variation from their specifications – therefore, it is vitally important that you measure your crib first prior to making a purchase decision.

Firmness

As babies develop, they require a firm mattress. A soft one may lead to overheating and rebreathing during sleep – both factors linked to SIDS (sudden infant death syndrome). Furthermore, firm mattresses promote spinal and bone growth during sleep time.

If you're shopping for a firm crib mattress, try to avoid options with padding or foam that could serve as breeding grounds for bacteria that could wreak havoc with your child's health.

One effective method of testing the firmness of your mattress is by pressing on its center and edges with your hand; if it springs back instantly, that indicates sufficient firmness for your baby.

Along with size and firmness, make sure the mattress fits snuggly to ensure there are no gaps in it. Babies often wriggle during sleep, and any gaps could prevent them from breathing comfortably or prevent their drop-side crib from working correctly; thus it is crucial that there be no gaps. Furthermore, look for fabric or vinyl covers free of phthalates as this will also help ensure safety for both mother and baby.

Edge support

While many individuals neglect the significance of edge support for mattresses, this feature can have a major effect on comfort and usability. By helping ensure that the bed maintains a firm surface right up to its edges and prevent sagging over time.

Before buying a crib mattress, be sure to test its edge support in person before making your selection. When lying near the edge of the mattress, evaluate how its edges respond under your weight; the best crib mattresses provide outstanding edge support which holds up over time.

There are various techniques for increasing edge support of mattresses, including butterfly side supports and steel perimeter frames with thick wires to encase spring units and provide greater stability on either side of the mattress. Other possibilities may include foam box encasements or polystyrene foam pillars as options.

Weight

Mattresses for your infant's crib or bassinet are among the most essential pieces of equipment needed when welcoming home your new bundle of joy. A firm mattress that fits snuggly will help reduce risks like suffocation and SIDS.

Consumer Product Safety Commission regulates crib mattresses to ensure they comply with specific safety standards, such as being at least 27 1/4 inches wide and 51 1/4 inches long and leaving no more than two fingers between it and its attachment points on crib rails.

There may be some leeway in these measurements, so you will want to ensure your mattress fits within them. In addition, seek out mattresses certified Oeko-Tex or Global Organic Textile Standard (GOTS), as these standards guarantee that materials used in it have been thoroughly screened for harmful chemicals or substances.
