Choosing the right baby cot mattress is crucial (parents, no pressure!). After all, your little bundle of joy would be spending anywhere from 14 to 19 hours a day (hopefully) sleeping. The cot mattress must be firm, supportive, well-fitting, free from harsh chemicals, easy to clean while still being cozy and comfortable. 

Few may wonder why the cot mattress should be firm? Wouldn’t that be uncomfortable for the newborn? Actually, a firm mattress ensures the baby gets proper support through the night and reduces the risk of sudden infant syndrome (SIDS).

The cot mattresses come in two standard sizes: Cot (60 x 120 cm) & Cotbed (70 x 140 cm). Make sure the mattress perfectly fits the cot bed such that there are no gaps that may pose a danger.

Just like buying an adult mattress, choosing a cot mattress can be confusing, especially with so many options available in the UK market. Here’s where we come in! To help you with the decision-making, we’ve analysed and researched dozens of UK cot mattresses to come up with our top 8 picks across different categories.

Buyers Guide: Factors to consider when buying a baby cot mattress

Wondering what to look for when buying a cot mattress? Let us help you here with our buyer’s guide so that it gets easier for you to select the one according to your needs.


Look for mattresses marked with a BS number as it implies that they conform to the norms of the British safety standards. The mattress should have one or more of these BS certifications:

  • BS 1877-10:2011+A1:2012 
  • BS 7177:1996 
  • BS EN 16890:2017 

If it does have a BS number, it means the mattress has been checked for all basic safety requirements in the UK. They are least likely to cause SIDS (Sudden Infant Death Syndrome) or be hazardous for your baby’s health. You can breathe a sigh of relief.

Firm is good

Experts say the firmer the mattress, the better, since firm mattresses lower the risk of SIDS. Ensure that the mattress you choose is firm as it maximises the development of the baby by providing the resistance necessary to strengthen their muscles. You can try and press your hand into the centre and corners of the mattress and check for its firmness yourself. If it bounces back to its original shape immediately, it is good to go.

Size and dimensions:

Cot mattresses come in two sizes: Cot (120 x 60cm) and Cotbed (140 x 70cm) respectively. If you need larger or smaller sizes than these usual standard sizes in the UK, you may have to get them custom-made. It is recommended that you select a mattress that is at least 10cm thick. Add a waterproof cover or mattress protector for better protection.

Mattress Types

Now that you have learnt about the factors you need to keep in mind while picking the mattress for the baby cot bed, let us guide you further with the types of mattresses you can choose to buy.

  • Foam cot mattress: This is the least expensive of all types of mattresses. Easy to maintain and clean. These mattresses provide good support to your baby. But they tend to lose shape over time; hence, it is better for only short-term use.
  • Spring or pocket spring cot mattress: The costliest type of cot mattress but also the best. These are very supportive, durable, and breathable. They’re usually made of spring coil core with comfort top layers. Some of them are also dual-sided, with one side firm for infants and the other side soft for toddlers.
  • Coir or natural coconut fibre cot: These all-natural cot mattresses have a core of coconut fibre with natural latex or foam comfort layer. They are breathable, firm and durable.
  • Hypoallergenic: Several of the cot mattresses now available are hypoallergenic. They come treated against bacteria or dust mites to keep your baby healthy. Though this would add to your cost, it helps you to keep allergies away.

Wrapping Up

Every parent wants the best for their baby. Sleep health is crucial for newborns as it helps in their growth and development. With our compilation and guide to choosing the best cot mattress in the UK for your little one, we hope we have been of some help. 

Now, you are just a step away from offering a good night’s sleep to the apple of your eye.
