The wrong choice can lead to insufficient support and comfort, poor quality sleep, and even worse; potential health risks for your little one. There’s a lot of information out there already, and I didn’t want to regurgitate the same old top 10 lists of the best baby cot mattresses.

Instead, I wanted to dig a little deeper and explore why these mattresses are being chosen in the first place, whether an expensive baby mattress is really worth the money, and ultimately, what the real cost of safety and comfort actually is.

It’s easy to see why this is the best cot mattress on many lists. The reviews for this mattress have been incredibly positive, with customers praising the natural materials, dual-sided design, and overall comfort. There are very few negative reviews. The main negative reviews have been the farm-like smell from the mattress, though this should dissipate over time. Most have praised the natural smell, and the fact that it’s been handmade with natural materials.

We noticed on one popular online forum that one user had complained of mould on the mattress. After selling her mattress and dismantling the cot she noticed black mould underneath the mattress. Anecdotal evidence like this is best taken with a pinch of salt, any mattress can develop mould in the wrong environment. We couldn’t find any other reports of mould appearing on the mattress.

Most cot mattresses are 10 cm thick; however, this mattress is only 8 cm thick. This is still within the recommended guidelines. According to nct.org.uk, a mattress should be no thinner than 8 cm.It was worth noting that many of the reviewers were using this mattress more as a temporary solution when away from home, like at their grandparents’ house, for example. You may want to take that into consideration.

Trying to find a correlation among those negative reviews is always difficult, but we can’t see anything unusual that stands out. A couple of people have mentioned that it’s hard, but that’s not unusual when it comes to cot mattresses, as they are supposed to be firm, and nearly every baby cot mattress I’ve come across will always get a few comments about being too hard.

Conclusion – So, should you spend a lot on a mattress?

Babies spend more time in their beds than any other place during those crucial first few years of life, so as a parent, it’s important to ensure that your child has the best mattress possible that you can afford. You don’t necessarily need to spend a lot of money, as there are some very good budget options available to you. Simply ensure that the mattress you choose is firm, flat, and waterproof, and that it is protected by a waterproof cover.

Both the budget options on this list and the premium options have a very good number of five-star reviews, which suggests that there is no need to spend a fortune. That being said, one of the best ways to decide between premium and budget is to consider the length of time you will be using each. The premium options come with long-term guarantees and are likely to last you much longer. With many of the expensive ones, you can simply flip the mattress over, and your toddler mattress will be good for a few more years.

FAQs Buyers and Safety Guide

What are the different types of mattresses?

On the market, there are numerous cot and cot bed mattresses.The main ones are spring mattresses, natural fibre (coir), and foam mattresses. A memory foam mattress should be avoided. Spring mattresses come in two different types: pocket sprung and open coil.

Each type of mattress offers its own benefits, from breathability to comfort levels, so it is best to choose the best one based on your needs and budget. You can also get some types that are a mix of both. For example, Mamas and Papas have a dual-core pocket spring cot mattress that also contains a level of natural coir.

TypeBenefitsNegatives
Sprung mattressSupport, comfort, and breathability. The open coils are good for dispersing heat, making them ideal for your child as they get older.Heavier and more expensive.
Pocket Sprung mattressEach spring works individually to create a superior support for your child. longer lasting and ideal for older childrenHeavier and more expensive
Natural fibres (Coir, wool, natural latex, mohair, horsetail fibres, and more)Breathable, temperature-controlling, and usually naturally hypoallergenicMost expensive
Foam mattressHigh-density foam is firm, lightweight, and cheapCan lose its shape after a while.

The best cot or cot bed mattress is one that ensures your baby’s safety.

Keeping your newborn baby safe is the main priority. The NHS and the Lullaby Trust advise that the cot or baby cot bed mattress should be a firm, flat, waterproof mattress in good condition.

The mattress should fit snugly against the sides of the cot or cot bed, with no gaps around the edges, so your baby’s head does not get trapped and suffocate.

The mattress should also comply with British safety standards. I have left links to the Lullaby Trust and the NHS website below. They provide a comprehensive guide to keeping your baby safe.

What are the current British safety standards for cot mattresses?

It has been established that the new European Standard, BS EN 16890: 2017, is the latest and most valid standard for cots and crib mattresses and supersedes BS 1877-10. It is also critical for parents to ensure that their cot mattress meets British Safety Standards before using it, and to replace it if necessary.

Can I use a second-hand mattress?

It is best to avoid second-hand mattresses if you don’t know how they were previously kept. The Lullaby Trust states that there have been studies that suggest an increased risk of SIDS (cot death) from mattresses acquired from outside the home, but this correlation has yet to be proven. If you do decide to use a second-hand mattress, you will need to make sure it’s still a firm and flat mattress and that it was previously protected by a waterproof cover.

What is the best thickness for a cot mattress?

A mattress should be no thinner than 8cm. A mattress that is around 10 cm thick is ideal, as this should provide enough support and comfort for your child.
