Mattress protectors do exactly what the name suggests – they protect the mattress beneath the protector. While many adults use mattress protectors to make their beds more comfortable or soft, they’re so much more vital for cot beds! Not only do mattress protectors make your little one’s bed more comfortable, but they can also protect the mattress from accidental spillages and more.
Don’t worry if you don’t already have a cot mattress protector; we’re going through the 12 best mattress protectors the market has to offer right now, including the Ultracool® Cotton Waterproof Baby Mattress Protector and Mocka Cot Mattress Protector.
We conduct our best cot mattress protector reviews through a combination of product testing, individual research, real buyer feedback and certified paediatrician approval.
We understand that there is no such thing as a “best cot mattress protector” for everyone, and what is best for one person might not be suitable for another. With this in mind, we assessed cot mattress protectors by comparing different features and specifications, and have highlighted the buyer we believe the product is best suited to.
We considered the following criteria below:
First up is the High & Dry Mattress Protector, designed with six layers to keep your little one far away from any damp spillages. It’s common for nappies to leak in the middle of the night, but that doesn’t make it any less uncomfortable for your baby! The High & Dry protector absorbs up to 5.5 times quicker than other protectors, drawing the liquid to the bottom of the protector while your child lays high and dry above it. Clever, right?!

The High & Dry Mattress Protector is made from cotton, which is both breathable and super soft on baby’s skin. This protector is the same size as most cot bed mattresses, which is 70 x 130 cm. The protector offers a snug fit, so it won’t slip off during the night, making the layered design less effective.
Below we have listed pros and cons based on real buyer feedback:
This mattress protector is good for parents who might’ve tried everything already but who are still experiencing leaky nappies. Sometimes, it’s just a phase that you have to wait out, and that’s what this mattress protector helps with. It’s machine washable for your convenience, too!
Bamboo is one of the most intriguing materials, and one that’s got plenty of properties that make it good for mattress protectors. Not only is it breathable and soft, which keeps your baby’s skin healthy, but it also promotes fluid absorption. This means that your baby can remain dry and enjoy their dreams while the mattress protector works to keep them away from any spillages. Bamboo is also anti-allergy, protecting them from dust mites and allergens.

The bamboo viscose material is super breathable and moisture-wicking, which makes this an excellent mattress protector for all seasons. It’ll keep your baby warm and cosy during the colder months and cooler during the summer. This takes away some of the parental worry of whether your baby is getting too warm or cold during the night, which is a nice touch.
Below we have listed pros and cons based on real buyer feedback:
This is a good mattress protector for cots with thick mattresses and for children who have accidents every now and then that frequently wake them up. This protector can be used from birth, so it’s a good option if you want to have your baby sleeping in their cot before six months.
The Ultracool® Cotton Waterproof Baby Mattress Protector is a lovely and breathable protection system for your baby’s mattress. It’s machine washable for your ease of use and convenience, while the Supima cotton percale cover is so comfortable you’ll want to sleep on it! This mattress protector is durable and well-made, with each stitch beautifully sewn to improve the protection layers.

This mattress protector comes with a cotton and viscose fill, which features an antimicrobial finish. This is a great feature to keep your child from breathing in potentially harmful particles. The polyester lining is completely waterproof, so the actual fill won’t get soiled and, therefore, lose this added feature. Only the cover and the fill lining will come into contact with any spillages.
Below we have listed pros and cons based on real buyer feedback:
The Ultracool® Cotton Waterproof Baby Mattress Protector is a good option if you have a higher budget for your mattress protector. It’s super comfy, features a fun pattern, is durable, and is machine-washable. It’s ticking all the boxes, that’s for sure!
The Mocka Cot Mattress Protector has been designed to protect the mattresses of their bestselling beds, the Vale Cot, Nero Cot, and more. However, it’s a universal size that should still fit the majority of standard mattresses! The cotton outer is lovely and soft against your baby’s skin while still keeping the fabric breathable enough to prevent overheating or disturbed sleep. The polyurethane filling protects the mattress from accidents.
Material (face) | Cotton |
Material (filling) | Polyester with polyurethane coating |
Size/dimensions | 70 x 132 x 19 cm |

Breathable material | Yes |
The Mocka mattress protector helps to prevent the growth of mould, bacteria, fungi, and mildew, not only protecting your little one from allergic and asthmatic symptoms but also lengthening the lifespan of your mattress. A mattress protector is much less expensive to replace than an entire mattress, after all!
Below we have listed pros and cons based on real buyer feedback:
This mattress protector is an excellent add-on if you’re already opting for one of Mocka’s cot bed mattresses, such as the Vale or Nero. It’s also a good option for other mattresses and cot beds, as long as you don’t mind hand washing the fabric every now and then.
Next up is a protector from Boori, which has been designed for their cot bed mattresses measuring 132 x 70 cm. However, as this is the standard size for most cot beds, you should be able to use this protector no matter what brand your mattress is.
Just bear in mind that this protector won’t fit the wider pre-2015 Boori Country cots or compact cots. This mattress protector can be used from birth as long as it fits snugly and there is no loose fabric bunching across the mattress.

The multi-layer design of the Baby Cot Fitted Mattress Protector keeps your baby dry and comfortable throughout the night while the fabric lining works hard to wick all the moisture deeper into the protector. Despite the multiple layers, each is breathable to keep the sleep space safe for babies to use from birth.
Below we have listed pros and cons based on real buyer feedback:
Again, this is a lovely mattress protector for anyone, but especially if you have a Boori mattress designed since 2015. You may as well add this protector to your basket as an essential extra if you’re planning on buying a Boori bed and mattress.
Another mattress protector designed and distributed in Australia, the Bubba Blue Breathe Easy mattress protector is so soft and comfortable that you might want to rest your eyes on it, too! The diamond-shaped padding sewn into the cotton cover offers extra comfort (if that’s even possible), and the waterproof lining protects from mould, bacteria, dust mites, and other allergens.
This mattress protector is fully fitted, covering every inch of the mattress’s sides and top. It’s the standardised size, so it should fit the majority of mattresses without an issue.

Not only is this protector soft and waterproof, but it’s also been described as thick and strong by previous users. Why settle for less when you could have the best of both worlds – strong and soft? We’ll take that any day – especially when it comes to protecting our little one’s mattress and sleep schedule!
Below we have listed pros and cons based on real buyer feedback:
The Bubba Blue Breathe Easy Waterproof Quilted Standard Cot Mattress Protector is an excellent choice for parents on a budget or who want to test out a protector before buying a more expensive one. This one might be all you need if your little one is a heavy sleeper or has infrequent bedtime accidents.
The Smart-Dri technology of this mattress is something to be admired, with four layers of material rather than just the two that most other protectors on the market have. Smart-Dri starts with a 100% cotton layer base, with a waterproof layer on top, then another absorbent layer, finished with another 100% cotton layer that your baby will lay on. These four layers help guide any spillages away from your baby, leaving them undisturbed until morning.

Using the Smart-Dri Mattress Protector Cot is super easy for parents everywhere. The manufacturer has considered everything, from making it waterproof to machine washable, as well as breathable, so you don’t have to worry about your baby getting too warm or clammy during the warmer nights. This protector has been designed to make your life easier, and that’s why we appreciate it so much!
Below we have listed pros and cons based on real buyer feedback:
You’re probably going to want a protector that is super absorbent and machine washable if your baby has lots of frequent accidents at night. Well, look no further – the Smart-Dri Mattress Protector Cot is a wonderful choice. The Smart-Dri technology is a lifesaver for parents experiencing frequent nighttime accidents.
The Clevamama Cotton Waterproof Cot Mattress Protector comes in two sizes – 60 x 120 cm or 70 x 140 cm. This is excellent news for parents using a compact cot or smaller mattress, as most of the protectors we’ve seen on the market are designed for larger cot sizes. This is the mattress protector for you if you’ve been worried about protecting your smaller mattress!
The hypoallergenic cotton cover is excellent for children with allergies, creating a barrier between dust mites and other allergens that might be sitting within their mattress.

This mattress protector comes with a super soft cotton cover, as well as a high-absorbency filling to draw all spillages away from your little one while they sleep. The waterproof layer then holds these liquids and prevents them from getting anywhere near the mattress underneath. You can machine wash this protector to remove any trapped liquids or smells and use it over and over again!
Below we have listed pros and cons based on real buyer feedback:
This is another excellent mattress protector for parents on a budget, as it completely protects the mattress without asking for a steep price. It’s also a great option for parents using a smaller 60 x 120 cm cot mattress, although there still is an option for larger cots.
The Compact Cot Fitted Mattress Protector is a soft and breathable protector designed specifically for Boori’s compact mattresses. However, it can usually be used for other smaller mattresses. Just bear in mind that this mattress protector measures 119 x 65, so if your mattress is any longer than that, it might not fit properly.
Despite this, the elasticated sides offer a secure fit around the mattress to prevent it from bunching or loosening as your little one sleeps. This keeps the sleep space safe, so you have one less thing to worry about!
Material (face) | Cotton |
Material (filling) | Lining – Polyurethane, Fill – Polyester |
Size/dimensions | 119 x 65 cm |

Another protector with four layers of absorption and protection, the Compact Cot Fitted Mattress Protector features a 100% cotton outer layer, an absorption layer, and a waterproof layer, finishing with a 100% polyester layer to keep the mattress beneath completely dry. This added protection keeps your mattress clean while your baby sleeps undisturbed. Everybody wins!
Below we have listed pros and cons based on real buyer feedback:
The Compact Cot Fitted Mattress Protector is probably best for people who already have a Boori compact cot or who are planning on getting one of these beds. Boori seems to have a different standard size for their cots than other manufacturers, so most of their accessories only fit their own mattresses and cots. This protector might be able to stretch over a 120 x 60 cm mattress, although you run the risk of ripping it.
Another entry to our list from Bubba Blue, this mattress protector is designed for standard cots sized 69 x 131, with a generous elasticated skirt of 19 cm. This fits almost all mattresses, no matter whether yours is super thick or on the thinner side.
This protector is made from bamboo and viscose, with a polyester waterproof layer. The materials of this sheet have been sustainably sourced, and the bamboo is environmentally friendly, so you’re also doing your bit for your local environment!

This mattress protector is good for the environment, effective at preventing leaks from reaching your mattress, and machine washable for your convenience.
Below we have listed pros and cons based on real buyer feedback:
This is an excellent option for you if you like to consider your environmental impact with your purchases. It’s made with sustainable fabrics that are better for the environment than cotton, which is a plus. Why not furnish your baby’s nursery with items that support their future world?
This super soft and supple mattress protector from Boori is the third we’ve talked about from this brand today – that’s just how much we enjoy their protectors! We’ve talked about protectors to fit post-2015 Boori cots, then Boori compact cots – and now this option fits the older Boori cot mattresses! This protector will fit it snugly to protect your mattress if you have an older Boori bed or a mattress measuring 77 x 132 cm, and ensure your little one’s sleep is undisturbed.

The Large Cot Fitted Mattress Protector features large elasticated wings on all sides, ensuring a snug fit day after day, night after night. This prevents it from coming loose while your baby moves, potentially becoming a suffocation hazard for your little one.
The waterproof and absorbent layers protect your mattress from staining and smells, giving you a much easier cleanup after accidents. Answer us this – Would you rather wash a machine washable mattress protector or the entire mattress itself?!
Below we have listed pros and cons based on real buyer feedback:
This is a safe, comfortable, and absorbent mattress protector to keep your little one floating on a dreamworld cloud if you have a Boori bed made before 2015 or one measuring 77 x 132 cm.
We’re sure your baby will love the Living Textiles Smart-Dri Organic Mattress Protector if you like the feel of organic cotton (and who doesn’t?!) With an outer cover made from 100% organic cotton, your little one will feel like they’re floating on a cloud while they sleep.
And, should they have any accidents or spillages, they won’t have to be woken up by it thanks to the moisture-wicking inner layers. The non-toxic, BPA/PVA-free waterproof layer then protects the mattress from any of this moisture, keeping everyone happy!

This universal mattress protector will come along for the journey, even if you want to change your baby’s bed down the line.
