Our cot mattress testing proves you can get an excellent cot bed mattress without having to break the bank.
If you’re on a budget you can find several of our Best Buy cot mattresses for less than £70.
Meanwhile, we’ve found Don’t Buy cot mattresses for more than £150, proving that price doesn’t necessarily equal a great product.
But we’ve also found some that impress that cost £100 or more.
What do you get for £100 or less?
Some, but not all, cot mattresses at this price have a waterproof layer and a removable, machine-washable cover to help make it much easier to clean up accidents.
A foam version is generally the least expensive type and these are usually made from a piece of high-density foam.
The Ikea Krummelur (£45) and Ikea Skonast (£70) both have a fixed inner cover and a removable outer cover that can be cleaned at 60°C, so you can easily pop them into the wash to kill any germs or bacteria.
Open-coil spring and pocket spring cot mattresses are more expensive, but there are one or two available for around £100, for example the Baby Elegance Micro Pocket cot mattress (£100) and Mothercare Anti-Allergy Spring cot bed mattress (£90).
Popular cot mattresses for £100 or less

If you’re tempted by this reasonably priced mattress, read our Mothercare Anti-Allergy Spring Cot Bed Mattress review before you buy.
What do you get for more than £100?
Almost all of the cot mattresses we’ve tested that cost more than £100 are pocket spring (also known as pocket sprung).
Unlike a regular spring mattress, each spring in this type can move independently of the others, which is thought to be more comfortable and give better support.
More expensive cot mattresses also tend to be reversible, and have dedicated sides for babies and toddlers to give your child targeted body support depending on weight and size.
For example, the Silver Cross Superior cot mattress (£149) has a firmer sleep side for babies aged 0-18 months and a softer side for little ones aged 18 months and over.
If you’re looking for something different at this price, the Little Green Sheep Natural Twist cot mattress (£150) is made of coconut, wool and natural latex on the inside, and the outside is made from cotton.
Coir or natural fibre cot mattresses are much less common than foam, coil or pocket spring, and they’re expensive because they cost more to produce.
But they may appeal if you’re after one that’s made from natural components, not chemically treated and free from toxins.

Five tips to buy the best cot mattress, whatever your budget
- A firm and flat mattress is safest for your baby, according to the Lullaby Trust. Assess this by pressing your hand firmly into the centre and edges of a mattress. There should be some resistance and it should bounce back immediately.
- Size is key. There shouldn’t be any gaps between the mattress and the cot or cot bed where your baby could potentially trap limbs. The majority of those we test are 140cm x 70cm, but we’ve also tested some that are 120cm x 60cm.
- Opt for one that’s at least 10cm thick to ensure that no part of your child’s body sinks through the mattress and touches the cot bed frame below.
- A mattress cover is helpful in the case of accidents.
- Your child will triple in weight developing from a baby into a pre-schooler, so a durable cot mattress that doesn’t lose body support or firmness is vital. Our cot mattress reviews tell you which will support best over time.
