Our tough cot mattress tests have uncovered four new Best Buys, including our highest-rated cot mattress, as well as our lowest scoring.
If you’re a new parent looking for a cot bed mattress, you’d be forgiven for thinking that they’re all pretty much the same. But, just like mattresses for your bed, there’s a vast difference in the level of body support different cot mattresses give to your baby and how well that support holds up over several years of use.
Our reviews have also found that price and brand are no guarantee of the best night’s sleep for your baby. We’ve found cot mattresses for under £60 that score more highly in our tests than others costing more than double the price.
Our latest cot mattress reviews include mattresses from John Lewis, Mothercare, Mamas & Papas and The White Company.
Head to our round-up of the best cot mattresses to see the most impressive on test.
Or read on to find out more about the differences you can expect between cot mattresses that cost less than a week’s worth of new baby outfits, and those that rival some cot beds on price.
John Lewis Premium Foam Cot Bed Mattress (£60)
This John Lewis Premium Foam Cot Bed Mattress costs half the price of the £140 pocket-sprung version (Baby Sleep Pocket Spring Cot Bed Mattress from John Lewis).
Foam cot mattresses are the least expensive type of cot mattress. They’re very simple, normally comprising a piece of high-density foam with a wipe-clean, waterproof PVC cover. Some will come with two sides: a cotton side and a wipe-clean side.
The John Lewis Premium Foam Cot Bed Mattress comes with an adjustable waterproof layer surrounding the foam core, as well as a removable cover that’s 75% cotton, and machine-washable at 60 degrees on a gentle cycle – both handy for little accidents that will occur.
But the waterproof layer doesn’t cover the whole mattress and the areas without the protection will absorb fluid.
We test all the cot mattresses we review for support, durability and how good they are at withstanding leaks. Find out what we discovered in our John Lewis Premium Foam Cot Bed Mattress review.
Cosatto Cumfi Kip Cot Bed Mattress (£60)
Cosatto is so convinced you’ll love its Cumfi Kip cot bed mattress that it comes with a four-year guarantee, although you must remember to register the product after buying it to activate the warranty.
Foam mattresses are generally very light (which make them easier to move or flip), and this one weighs 3.1kg (the same as the John Lewis Premium Foam Cot Bed Mattress).
We use a 12kg and 20kg dummy to test how well this cot mattress, and all the others we review, supports your child as he or she grows. We also test on each side, as most cot mattresses are reversible. Check out our Cosatto Cumfi Kip Cot Bed Mattress review to see whether this cot bed mattress will sag, or if it will provide full body support.
Mamas and Papas Pocket Sprung Cot Bed Mattress (£99)
The average baby triples its birthweight by the age of one and grows an incredible 10 inches in that first year, so it’s very important for a cot mattress to adapt to your little one’s changing weight and shape.
The Mamas and Papas Sprung Cot Bed Mattress claims to provide a high level of long-term support to your baby’s growing spine, thanks to the individually pocketed springs that work independently to give tailored body support.
It also has a machine-washable cover and a waterproof panel to keep the core of the mattress clean, dry and hygienic. Take a look at our Mamas and Papas Sprung Cot Bed Mattress review to see our star ratings for support, durability, permeability and washability.
Mothercare Anti-Allergy Spring Cot Bed Mattress (£90)
Usually you pay a hefty price tag for a product that’s hypoallergenic, but the Mothercare Anti-Allergy Spring Cot Bed Mattress is significantly cheaper than the other anti-allergy cot bed mattresses we’ve tested.
It also has a layer of PVC on top, which makes this cot bed mattress resistant to leaks as well as easy to clean. That means it shouldn’t become a breeding ground for bad bacteria if there are any night-time accidents.
But before you bag yourself a potential bargain, find out whether it’s suitably firm and supportive for your baby, as well as durable, by looking over our Mothercare Anti-Allergy Spring Cot Bed Mattress review. Otherwise you might have to buy another one after a few years, before your child has outgrown their cot bed.
Merifor Serenity Cot Bed Mattress (£220)
The Merifor Serenity Cot Bed Mattress isn’t cheap, but it’s billed as a mattress for little ones susceptible to nasal problems. It’s designed to be both anti-allergy and anti-mite, plus it has even been given the Allergy UK Seal of Approval and a three-year guarantee.
This pocket-spring mattress has two covers: the removable outer cover is washable at 60°C to help kill germs and bugs, while the inner, non-removable cover claims to be sealed and waterproof, so that it stays hygienic and dry.
