Foam vs Coil Crib Mattress: What You Need To Know

Your infant is going to sleep on their mattress for much of their newborn life. Once they are old enough, they may use the same mattress to sleep on in their toddler bed. The best thing that you can do for them is to buy them a good quality mattress that’s going to last them many years.

But how is this done? What do you look for? Do you want durable or soft? When we take a look at a foam vs coil crib mattress, we see many differences. Each one of these has its own set of characteristics that make them stand out from the other. Let’s check out what each one has to offer and which one is the better of the two.

Foam Mattresses

Foam mattresses have the most variety out of all of the bed types. They can come in regular blocks of foam, gel and memory foam, and organic foams. These are usually the cheapest type of mattress on the market, but just because they’re cheap, doesn’t mean they don’t have good qualities.

The Good and Bad Side

Foam Pros

  • Generally cost less
  • Lightweight
  • More variety for firmnesses
  • More organic varieties available

Foam Cons

  • Less durable
  • Indentations are easy to make
  • Can lack edge support

Foam Mattress Features


Foam mattresses are known most for being the most affordable out of all of the other types. You can find them anywhere from a mere $30 to over $300 for the organic kind. Usually, the cheaper ones aren’t going to hold up as well as the more expensive ones made with a denser foam, but they are great if you’re on a tight budget or need something in a pinch.


Foam mattresses have the ability to be organic whereas innersprings aren’t completely eco-friendly. It’s tough to make coil organic. This is what makes foam mattresses more appealing than coil. Organic foam mattresses are healthier for your children because they aren’t made with the toxic chemicals that traditional foam is made with. You should also know that just because it says it’s CertiPUR-US Certified or GREENGUARD gold certified, doesn’t make it organic.

Eco friendly mattresses are just made with more environmentally materials, but they are still much safer for your baby than those that aren’t. If you want a unique type of mattress that’s healthy for your child and completely organic, I would recommend the Newton Wovenaire.

When it comes to comfort, foam mattresses have the widest range of comfort levels. You can get foam mattress that are made from memory foam or gel foam. These types are what can be found in some of the most popular adult mattresses around the globe. Memory foam is known for its contouring abilities and gel foam is best for keeping body temperatures regulated while conforming to your body.

If your toddler or your baby sleep better on your memory foam or gel foam mattress, it may be a good option to get them their own mattress with the same qualities. The gel mattresses are particularly ideal for babies or toddlers who sleep hot and seem to wake up covered in sweat.

Edge Support

Foam mattresses aren’t best known for their edge supporting abilities. It’s important that the edges of these beds aren’t sagging for many reasons.

  • If the mattress is too small for the crib as it is, the lack in edge support can suck the baby in the crack and it can pose an entrapment risk, possibly leading to SIDS.
  • If your toddler is prone to sleeping too close to the edge of the bed, the lack in support may aid them in falling off of the bed. If this is a concern, you can always invest in a bedrail.
  • Not all of these foam mattresses lack edge support. Sometimes, you will find these types of beds with reinforced edges to keep the bed from sinking on the sides.


After a while, foam usually loses its shape or starts to break down from the core. This is particularly bad if you plan to use it for a future child or it was give to your as a hand-me-down. This takes away the support that a baby will need. It’s best that foam mattresses aren’t a long term solution because of their quick breakdown. These definitely aren’t as durable as good quality innerspring ones are.

Coil Mattresses

Coil mattresses, or innerspring, are the more durable option. Sure, they are heavier and cost more, but they do last longer and they are the best option for long term use and hand-me-downs. Here’s how these mattresses differ from foam.

The Good and Bad Side

Coil Pros

  • Better support
  • Longer lasting
  • More durable
  • Good edge support

Coil Cons

  • Heavier than foam
  • More expensive usually
  • Poor quality cover can lead to exposed or uncomfortable coils

Coil Mattress Features


Coil mattresses do tend to cost more than foam ones because of what they’re composed of. They aren’t just a couple of slabs of foam blocks pieced together, they are coils, comfort foams, casings, and more. The good innerspring crib mattresses are going to cost you a few hundred dollars and up. Although, you’re getting the most for your investment.

Organic/Eco Friendly

You may not be able to find a completely organic innerspring mattress, but they do makes ones that are more eco-friendly, such as the Simmons Beautyrest Beginnings Sleepy Whispers. These ones are made with durable coils, a comfort layer, air holes for breathability, and they’re waterproof amongst other things.


Coil mattresses are generally not as soft as some of the foam mattresses, but since support is more important than comfort to a baby, this is where the innerspring comes in handy. These mattresses are more supportive as well because the coils evenly distribute the weight of the child, contouring to their body better for good spinal alignment.

It’s also important to know that inside of these mattresses are comfort layers that give just enough cushion to be comfortable while allowing the support to be maintained. The cushion aso takes away from any feeling of springs there may be.

Edge Support

Since edge support is so important for both toddlers and infants, this is where innerspring mattresses trump foam. Mattresses made with coils usually have a coil lined edge, giving it the support it needs. The coil lined edges also add to the durability of the bed, making it last even longer and prevent sagging. WIth these beds, you won’t need to use a bedrail as often.


I have expressed this many times throughout this article, but the coil mattresses are more durable than the foam mattresses. Since the springs are made from thick steel and because of this, the coils can handle the weight of a child better than most foams can. You won’t find them sinking in as much on these ones. So there is no reason for the core of the mattress to give way to the weight.

Since these are so durable, the can be used for many years and make great hand-me-down beds. These are the ones that are made for long term use.


As you can see from the information provided, there are benefits to both and both of them have their weak points. The one you should choose is based solely upon what you are looking to get out of the mattress. If you want something that is going to be used long term, the coil is your best bet. If you want something more like your own bed that you child loves, memory foam mattresses are great for that.

I gave a couple of options above for good choices in mattresses, but if you want something that’s both comfortable and supportive, giving you the best of both worlds, I would recommend the Naturepedic. It’s in our organic category and it’s got the durable springs, good edge support, it’s dual-sided and it’s comfortable.
