Why Your Baby Cot Mattress Dips or Dents

NightyNite® sprung mattresses offer more support

The choice of foam the manufacturer decides on is often dictated by “the minimum required to conform to British Standards” or by “the pressure of getting to a price point” or as we do “put comfort, performance and durability as a priority.”

Here is how foam rating works in sprung and pocket sprung cot mattresses:-

The springs in cot mattresses are covered by a top and bottom layer of only 2 cm deep foam, this foam has the pressure of the weight of a baby from above and the pressure from the springs below. Also be aware foam does not like heat, weight and damp which is what a baby is! Consequently all these things contribute to weakening the foam and making it dip or dent.

Currently the foam used to cover the springs by the best chains stores, department stores and some internet companies is 24/130 or equivalent quality, it passes the British Standard.

24/130 -The first number “24” is the weight of the foam per kilo and indicates the density or the foam and this affects the durability. The second number “130” is the amount of pressure in Newtons it takes to compress the foam to 40% of its size. This measurement is called Indentation Load Deflection (ILD) and this assess the firmness or the feel of foam and how it yields to weight and pressure.

Our NightyNite® mattresses use 30/150 foam this is a huge step up in durability, support and comfort. Our mattresses are much less likely to dip or sink. Your baby will be using a cot mattress for over 9000 hours and a cot bed mattress for up to 20000 hours, making it a worthwhile investment.

For the past 15 years we have also made a pocket sprung mattress called the “Nightynite® Excellence Easychange®” this is made with 50/215 foam, we guarantee it for 5 years against dipping or sinking. Nobody in the UK comes close to producing a mattress that offers more in the way of – comfort, safety, breathability, temperature control, hygiene, durability, waterproof protection

We also lead the baby mattress market with our Easychange® design. Two zip off interchangeable machine washable toppers in either microfibre or Coolmax with Maxispace, secured on a waterproof protective cover on a longer lasting base. Feedback from customers that have bought these say “Why buy any other mattress”
