Best Cot Bed Mattress in the UK for 2023

With over 70 years of bed making experience, Silentnight is one of Britain’s most popular mattress brands. All their beds (both for adults and babies) are handmade in the UK and are regularly tested to meet the highest British and European standards.

The Silentnight cot bed mattress has many features that put it among the top three best-rated; however, it’s in the construction where this model really shines. 

Designed with mini-pocket springs, this cot bed has a support system that is firm enough for your baby but sufficiently responsive to adapt to your child’s growing body.  What’s more, the foam is chemically treated to provide the cleanest and freshest slumber for your tiny sleeper. 

The Luxury Pocket mattress is encased in a 3D mesh cover that boosts airflow, allowing the body to breathe freely during the night, thus ensuring better sleep. Moreover, the surface has been treated with Purotex, a 100% natural technology to keep allergens, dust mites and moisture away from your child. The outer shell is also easily removable and machine-washable for when those inevitable incidents and accidents happen.

The Silentnight Safe Nights mattress is sold with a 3-year warranty and arrives at your door anywhere in the UK and Northern Ireland within two weeks. If for whatever reason, you are not happy with your purchase, you can return it within the first 14 days or replace it with another product in 60 days. 

This bed is a bit on the higher end of the spectrum, price-wise. Nevertheless, it provides excellent value for money, delivering superior comfort and support packed in an amazingly well-designed baby mattress. Not to mention that that is chemical-free and naturally treated to make sure your baby is safe from various allergens and harmful particles. In short, it ticks all the boxes when it comes to choosing the best cot bed mattress in the UK. 

Another model from the Silentnight product range, the Safe Nights Essentials Cot Mattress, is inexpensive, comfortable, safe and supportive. 

Like all other beds from this brand, the Silentnight Safe Nights Essentials cot mattress is made of the finest, premium British materials.

These materials include a core made out of 100% recyclable Eco Comfort Fibre layers, which is much safer for babies than foam beds. What’s more, the body is odour and chemical-free, provides excellent natural air circulation, and is incredibly firm, so unlikely to sag or dip over time. 

The foam-free core is placed within a knit cover that is hypoallergenic and machine-washable for easy maintenance and care. 

This Silentnight model is cheaper than the Luxury Pocket, but that doesn’t mean it ranks lower in quality. In fact, it comes highly recommended by plenty of best cot bed mattress reviews by happy customers who declare their children simply love napping on this bed. 

The brand offers the same warranty, delivery, and exchange conditions for all its cot mattresses. That means all beds are covered by a manufacturer’s warranty for three years and can be returned or exchanged within the first two weeks of purchase. 

Affordable and durable, this bed is ideal for parents on a budget. However, it does not sacrifice comfort and support for the sake of the price. Simply put, it still provides the responsiveness, temperature regulation and superior design one would expect from a reputable mattress company like Silentnight. 

Mamas & Papas Essential Pocket Spring Cot Mattress is one of the highest-rated baby beds and our top choice for the best cot mattress in the UK. 

What makes this bed stand out from the competition? 

First off, it is incredibly well-built, with pocket springs that work independently, meaning they contour and respond to changing weights and shape. In other words, the mattress will adapt to the size and shape of your growing baby and is thus suitable from birth and beyond. The springs also promote airflow and combined with the fibre core lining, the bed keeps your child cool and comfy through the night. 

The Mamas and Papas cot mattress is further equipped with crush-resistant walls for additional support and a hypoallergenic cover to protect your little one from environmental triggers. 

This mattress is also unbelievably easy to care for. It is encased in a waterproof, removable and machine-washable top cover, while the inner shell can be wiped down to ensure the core stays dry and fresh. You might need to rotate and flip the mattress occasionally to air it out and keep it in shape, but this should not take up a lot of your time and effort. 

Best of all, this UK-made cot mattress is one of the lowest-priced on the market. Plus, it is sold with a two-year manufacturer’s warranty and is delivered free-of-charge for orders over £50 within five working days. 

The Mamas and Papas cot mattress is among the best choices available right now. It’s safe, secure, and inexpensive—all the features you should look for when buying a mattress for the most important little person in your life. 

Made from organic materials from cover to core, the Obaby cot bed mattress is a parents’ favourite and one of the best green options on the market right now. 

What exactly goes into the construction of this cot bed mattress?

The inner core consists of coconut coir bonded with latex to give the bed some bounce and adjust to the baby as it grows and develops. The combination of latex and coconut coir also increases the bed’s breathability, durability, and resilience. 

The interior of the mattress is then wrapped in soft and plush natural lambswool, which not only provides optimal protection against dust mites and allergens but also helps regulate the baby’s body temperature. 

The entire construction of the Obaby mattress is encased in an organic, super-gentle bamboo cover. The natural cover protects the bed from bacteria and odours, and it’s more breathable and softer than cotton, thus providing superior temperature regulation. On top of that, it’s removable for easy cleaning after spillages, leaks and other “accidents”. 

Parents and babies have a lot to like about the Obaby cot bed mattress. In addition to its high-quality, eco-friendly materials, it is reasonably priced and sold with a generous warranty of five years, which can be redeemed by registering on the official website in the first 28 days of purchase. 

All in all, this Obaby mattress is an excellent choice for anyone looking for a 100% natural and safe option for their children.

Made and designed in Britain, the Silver Cross Superior cot bed mattress features six layers of high-quality materials for ergonomic support and superior comfort for babies of all ages—from newborns to toddlers. 

What exactly makes this bed ideal for your growing baby?

For starters, the Silver Cross cot bed mattress is fully reversible. Thanks to the Dual Care design, this bed comes with a firmer side for babies aged 0-18 months and a softer side to suit little ones aged 18 months and over. 

On top of that, the Silver Cross Superior features a total of 190 pocketed springs in the core that actively respond to your baby growing and changing shape. The coils are cushioned between a layer of polyester padding and high-density nursery-grade foam for added comfort, protection and durability. 

Another standout feature of this cot bed mattress is the unique True Fit element, i.e. the mattress has square-shaped corners for exceptional edge support, keeping the surface flat at all times and providing extra protection for your tiny angel. 

Finally, the cover is made from Tencel—a breathable, soft and natural fabric with extraordinary moisture-wicking qualities that will keep your infant dry and cool through the night. Not to mention that the cover is waterproof, hypoallergenic and antimicrobial, and it can be removed and cleaned in any standard washing machine, to boot. 

The Silver Cross cot bed mattress does not come cheap. However, bear in mind that it is of exceptional quality, quite durable and suited to babies of all ages and sizes, so consider it a long-term investment into your child’s quality slumber. 

An award-winning brand, Eve Sleep has applied the renowned expertise and skills that has made them so popular among adult users to tiny sleepers as well. The design of their cot mattress closely follows that of their premium Eve beds and is guaranteed to provide the same level of comfort and support.

The Eve baby cot mattress is a 5-layer bed that combines foam and pocketed springs to ensure a safe, cool, and comfy sleeping environment for your little cherub. The premium foam ensures the bed stays flat and doesn’t dip or sag, while the pocketed springs adapt to your baby’s growth and boost airflow. 

Moving up from the core, the cover is made of soft, breathable and antibacterial material to keep bugs and mites away from your kids. To make maintenance easier for busy mommies, the cover features a waterproof laminate layer (to protect the core from “accidents”), and it is also removable and washable. 

In addition to being exceptionally comfortable, the Eve cot mattress is versatile too — it’s available in two sizes: a cot mattress and a cot bed mattress, and thus suitable for children from birth to the age of six. 

On top of all these perks, the Eve bed is quite well-priced and offered with a 5-year guarantee and a 30 night trial period.

Best of all, Eve mattresses, especially their baby collection, have been tested and certified as compliant with all environmental, health and safety standards. The foams in the Eve baby mattress are nursery-grade, as well as Certi-PUR and Oeko-tex Standard 100 Class I certified.  

Eve Sleep is a well-established company that is completely transparent about their design, manufacturing, and delivery process. Buying this brand means parents can rest assured that their precious munchkins are safe, comfy and cool as they go off into dreamland. 

If you’re on the hunt for safety and allergy protection in a supportive and cosy baby mattress, look no further than Little Big Dream’s Sleep Tight Cot Mattress.  

The key is in the cover. The Sleep Tight cot bed is encased in ultra-breathable, anti-allergy fabric that protects your bundle of joy from potentially harmful materials and triggers, as well as keeping irritation through the night at a minimum. 

The cover is also easily removable and washable, so it stays fresh and clean all the time. Like all other baby beds, this mattress has an inner, water-repellent cover that keeps the core safe from spills and leaks. The difference here is that this waterproof layer can be used as an outer cover when the removable one is in the wash. 

This Dreams cot mattress also features 220 pocket springs in the core that effortlessly adapt to your baby’s changing shape and size. There is no foam in the design and so no trace of the potentially dangerous chemicals commonly used in foam manufacturing.  

Available for only £129, the Sleep Tight baby mattress comes with a 40-night Comfort Guarantee, meaning if you’re not satisfied with the mattress between 30 and 40 nights of use, Dreams will exchange it for another mattress in the same size.
