A cot mattress needs to be firm, flat and durable. But our safety tests show that popular brands don't always guarantee you'll get a mattress you'll be happy with.

Read on to find out which brands we asked parents about that have left parents wanting more, and which brands parents have reported the least issues with.

Which? cot mattress tests

Our cot mattress testing is tough.

We believe it is essential, to ensure unsafe products are held to account, so parents can make the best choices.

We test to the latest version of the cot mattress safety standard BS EN 16890:2017 + A1:2021. It's voluntary, meaning manufacturers don't have to meet it, but we often test cot mattresses that claim to meet this voluntary standard and fail.

Our tests check for hazards including:

  • Choking hazards - such as zips that break too easily, loose stickers, or the inner material of the cot mattress being too easily accessible.
  • Entrapment hazards - cot mattresses too small for their cot can have gaps between the mattress and bed frame, that a baby's limb could get trapped in and cause injury.
  • Suffocation hazards - a cot mattress that's too soft can present a suffocation risk for a newborn baby.

We also check a mattress is durable enough to remain supportive and safe to use after several years of use.

Only cot mattresses that are firm, durable and safe get our Best Buy recommendation.
