Top 6 Best Mattresses for Co-Sleeping

If you’ve been considering co-sleeping with your child, you’ll likely need to get a new mattress that’s safe for co-sleeping.

If your next question is why you can’t use your current mattress, the read on to discover all the reasons why you shouldn’t continue sleeping on your old mattress.

Why buy a new mattress?

Safety and hygiene are primary concerns here. But there are also a number of other reasons why you need to switch mattresses:

Mattress composition

Many regular adult mattresses contain all types of materials, some even toxic. These can make the mattress less than baby friendly, so pay attention to the composition of the mattress. The best options in this case are 100%, all-natural organic mattresses without any harmful materials.


Babies need to sleep on a firmer surface for an optimal sleep experience. Many adult mattresses may be too soft for this. Also, if you’ve been sleeping on the same mattress for years now, its firmness levels become questionable. The mattress may have become softer and sagged over the years.

Having undergone years of use, mattresses don’t remain as clean as when they were new. This is probably not the best surface you want to put your baby on. And even if you have been keeping the mattress clean, extensive use of any surface will suffer and compromise its hygiene.


To look for a mattress to co-sleep on, only consider models that are manufactured from lightweight and breathable materials. When sleeping with a smaller infant, make sure never to have overstuffed pillowtops which can potentially sink the baby’s head and present a hazard.


Choose a mattress that is easy to keep clean. For this, look at models that come with removable, zippered covered which can be tossed into the wash whenever needed.

Keeping these pointers in mind, here is a look at the best mattresses for co-sleeping available in the current market:
