Whether this is your first child or you’re a seasoned parenting pro, putting your little one to bed can be an anxiety-filled experience. The mattress in their cot needs to be comfortable, supportive, and, above all, safe. But what features should you look for and what should you avoid? After my first child was born last year, I was completely overwhelmed. Every potential product purchase filled me with anxiety. While there are plenty of baby guides available, I had a difficult time finding accurate info on what type of mattress to buy for my daughter’s cot bed.
I took my best guess and bought a mattress I thought would work. Later on, as life settled down, I decided to revisit my struggle to find the best cot bed mattress reviews. Certainly, other people had the same questions I did. So I decided to do my own research and document it. My complete guide helps remove the guesswork and gives you advice for finding the perfect choice for baby.
Cot Bed Mattress Reviews
When I first started shopping for my toddler mattress I was overwhelmed by all the options. The goal of my guide is to prevent that from happening to you.

Developed with help from Trinity College Dublin, ClevaFoam was created from the ground up with the goal of providing safe, healthy support for babies and toddlers.

This unique material helps reduce Flat Head Syndrome, supports developing joints and encourages restful sleep. Dimensions are 140 x 70 x 9.5 cm for the cotbed mattress or 120 x 60 for the cot mattress.
Shopping For The Best Cot Bed Mattress
First, there are a few tips you’ll want to consider when you’re in search of a new toddler mattress whether it’s for a cot or cot bed:
Always Buy New
When a baby is on the way, you can often save a ton of money by accepting previously used items from other parents you know or using hand-me-downs from your other children. But you always want to purchase a completely new mattress for each child. This is the only way to ensure proper hygiene.
Improperly stored mattresses can develop mould, which isn’t always easy to see. Plus, toddler mattresses are generally exposed to a lot of liquids including many biological fluids. If not cleaned correctly, bacteria can thrive. You can’t always detect a dirty mattress by sight and smell, so the only way to ensure proper hygiene is to buy new.
Should You Care About Warranties?
Yes and no. A warranty can be great if your toddler mattress arrives defective or develops an obvious problem right away. But don’t pay extra for a warranty and don’t put too much stock into a warranty which applies for years down the line. As long as you keep the mattress clean, a well-built one will typically last for many years without issue.
The Two Types Of Mattresses
There are two main types of cot bed mattresses: foam and inner-spring. Both have a lot of benefits and neither is particularly better than the other. Still, each type has a few unique features. Let’s take a look at both:
1. Spring Mattresses
When shopping for a spring mattress you want to consider the number of layers, what each layer is made of and the type of covering is used.
Generally, more layers equal better quality. You want the springs to be made with high-gauge steel. This results in more cushioning and better overall support. As the number and quality of springs increases, so does the weight. However, baby mattresses rarely become heavy enough to be an issue.
When selecting a spring mattress, pay attention to border rods. These are rods that line the inside perimeter. They provide firmness, durable surfaces, and side support. Border rods are a necessity in a spring mattress because they prevent sagging if your child stands near the edge. Without border rods, your child can lose their balance and potentially become injured.
Check for coil count. This is the number of springs inside the mattress. A high coil count is often a big part of marketing efforts. While many springs can lead to increased firmness and stability, that’s not always the case. A better way to evaluate is to look at the quality of each coil. You want coils which have a high percentage of steel in each spring unit. Steel thickness ranges from 19 to 12.5 gauge. The lower gauge type is thicker.
The best baby mattress will have a medium to high coil count, and each coil will have a reasonably thick gauge. Generally, you want to aim for a coil count between 125 and 150 with a gauge or 15.5 or lower. Be wary of extremely high coil counts, especially counts over 200. The gauge strength will typically be very low. This type of mattress won’t be nearly the same level of firmness and comfort as one with fewer coils but stronger individual springs.
Of course, you certainly don’t want the coils to poke through the surface. That’s where the insulating pad comes in. This is a thick pad on top of the springs which prevents any accidental injury.
Even cheap mattress pads will likely feel comfortable right away. What you want is a durable pad which will provide protection over a long period of time. Lower quality pads are made from polyester or cloth. High-quality pads are made from shredded coconut shells, also called “coir fibre.”
Next is the cushioning layer. This is the layer above the coils and below the pad. Avoid polyester cushioning, which has a tendency to form pockets. Pockets are areas where the coils poke through the material. The best cushioning layers are made from a blend of foam, cotton, and polyester. In this case, polyester is fine because it’s augmented by the foam and cotton.
There’s a trick to know here. A high-quality product will list the components of the mattress pad and cushioning layer right up front. You’ll easily be able to find a description on the manufacturer’s website, mattress tag and elsewhere. If you can’t find this info with ease, the chances are pretty good the content of the product are cheap.
So that’s how you can go about finding the best cot bed mattress with springs. Let’s move on to tips on finding a suitable choice when it’s made of foam:
2. Foam Mattresses
Aside from springs, the other option is foam. Most memory foam mattresses are made from polyurethane, but some have proprietary foam construction made from unique materials. Foam is lightweight, waterproof, and conforms well to the shape of anybody, even tiny ones.
When shopping for a foam mattress, you want to test the firmness. You’re looking for something which is firm, resilient, and even a bit on the heavy side. It’s okay if a baby mattress is slightly stiff and heavy at first. Foam will typically soften up over time.
Check foam firmness by pressing on the centre and the edges. The indentation shouldn’t last long. You want almost instant snapback. Fold which molds too easily doesn’t provide enough support.
Density is another important factor. The denser the foam is, the better. Density can be determined by placing your hands on each side of the mattress and pressing towards the centre. Your hands should not be able to touch – ideally, they shouldn’t even come close. The more resistance, the denser the foam.
Both spring and foam mattresses will have a cover. These are usually made of either vinyl or fabric. Fabric breathes better, which makes the mattress cooler. Fabric covers are usually the best option if you live in an especially warm location. On the other hand, vinyl is more durable. Multilayered vinyl is puncture and tear-resistant. Plus, vinyl is often easier to clean. You simply wipe it down with a damp cloth.
If you want the most durable cover possible, look for three-ply vinyl. This triple lamination creates a tough outer shell which is very resistant to damage over the long term. A three-ply vinyl cover will typically last the longest out of any type of cover material.
Stay away from antimicrobial covers. While they seem like a good idea, they’re really nothing more than a marketing gimmick. The best way to prevent bacteria from forming on the mattress cover is to simply wipe it regularly with soap and water.
If you want to store your mattress for an extended period of time, follow these steps. Clean the cover with soap and water. Let it dry thoroughly (this is super important). Place the mattress in a special storage bag. Make sure the bag is clear because light helps prevent bacteria growth. Then store the bagged mattress in a dry, well-ventilated space. Avoid storing in a basement or attic.
What About The Smell?
You’ll notice a common complaint about many cot mattresses. They smell weird. In some cases, the smell can seem overpowering. What’s going on here? Don’t worry. This isn’t a sign of anything unusual or dangerous. It’s simply a side effect of the manufacturing process.
When an adult or baby mattress is made, it’s immediately sealed in airtight polythene packaging. This keeps it sterile, dry and clean. But the chemicals used to process the fabric and vinyl remains. When you open the package, the smells from the factory are, well, unleashed.
This chemical smell can be very unnatural and even downright unpleasant. But the solution is simple. You just need to give the mattress a day or two to air out. Place it in a well-ventilated area and let it sit. In most cases, the smell will disappear in no more than 48 hours.
Think of it like this: The “new” smell is proof that your mattress is clean and sterile. It’s actually a clear indication that your product contains no bacteria, toxins or anything else dangerous.
You can trust all of the cot bed mattress reviews mentioned above are of products which help keep your baby safe and comfortable. None of them contains dangerous chemicals or are fire hazards. Plus, they’re all designed specifically for the needs of growing newborns and infants.
If you specifically want to prevent Flat Head Syndrome, the Clevamama ClevaFoam Support and Poppy’s Playground have unique construction designed to help prevent it from developing.
My top recommendation for the best cot bed mattress is the Mother Nurture Luxury Spring. Combining the benefits of both spring and foam padding, this mattress blends comfort with breathability. Plus, the waterproof liner prevents liquids from seeping into the core – which is one of the major causes of baby mattress damage.
Another benefit of the Mother Nurture Luxury Spring is how long it lasts. You can buy this for a newborn but use it for years as your child grows into an infant. Easy to clean and completely hypoallergenic, your child’s cot bed will easily stay reliably hygienic.
Overall, I think this is certainly the clear winner, and it’s the one I have no hesitation in recommending to my friends.
Choosing the best cot bed mattress for your child can be nerve-wracking, but plenty of safe, comfortable options are available. Because, for a new parent, there’s no greater comfort than peace of mind.
