What size is a memory foam crib mattress?

All memory foam crib mattresses must meet the standard requirements of crib mattress sizing. This is 28″wide by 52″ long and no thicker than 6″ thick. 

What is a memory foam crib mattress used for?

A memory foam crib mattress is generally meant to be used for babies or toddlers. Many memory foam style mattresses have a “dual sided” design where they can be flipped from a firmer infant side to a softer toddler side. 

Things to consider before buying a memory foam crib mattress.

Frequency of Usage: Will this mattress be used for one baby or multiple babies? Will it need to accommodate an infant as well as a toddler? These are all questions you should ask yourself when deciding on which crib mattress to buy. If your mattress will need to be used for a longer period of time then we suggest going with one of the higher end mattresses. A budget friendly mattress may only last for a few years, while a higher end mattress can last for multiple babies and toddlers. 

Price: Generally speaking, the more expensive the mattress the higher quality materials and the longer it will last. Our best all around  pick is a great middle ground between quality materials and an affordable price. 

Is a foam or coil mattress better for babies?

All crib mattresses have to meet certain criteria in order to be sold and used by infants and children. This means that in terms of safety, foam and coil mattresses will both be great options. When choosing between foam and coil mattresses it is all about personal preference and what features you want for your child. A coil mattress is more traditional and will provide more bounce, it will also be much heavier than an all foam mattress. On the other hand, an all foam mattress is newer and generally utilizes newer technologies such as memory foam or latex.
