Newborn babies will spend a lot of their time relaxing within their cot and it’s crucial that you purchase the correct cot bed mattress. This improves the chance of them having a good night’s sleep as well as supporting their growing body.
Most mattresses used for cots are 140 x 70 or 120 x 60 cm in size but most have a tolerance in size of a few millimetres. If you own a baby travel cot, you may need a smaller mattress size to accommodate the internal space inside of the cot.

However, if you are on a tight budget, the Mother Nurture Classic is the best alternative that’s available in two different sizes.
