The Cot  Mattress Base Core

This can can be either:- Foam, Fibre, Springs, Pocket Springs, coir Lambswool or Latex or a combination of one or two or three of these components

The Cot Mattress Foam

Over 90% of all baby mattresses have a foam content. Foam is the key component and comes in a vast selection of qualities.To understand what you are buying it's worthwhile knowing how foam is classified. It's not that complicated.... honestly!

Foam quality is described in two numbers - the most common quality used in over 90% of all cot mattresses is 24/130 foam.

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 assesses the firmness or the feel of foam in the cot mattress. It indicates how it yields to weight and pressure and how long your cot mattress will last.

You may also see 24/130 foam classed as CMHR28, (this is a basic quality most companies use to pass the British Standard). Obviously as these numbers increase you will get a higher quality foam, This foam will last longer give more comfort and support.

It is vital your baby sleeps on a firm surface that will not dip or dent and give maximum support as you baby grows and gets heavier and more active. Nightynite® cot mattresses use.a much higher quality foam than 24/130.  We use  30 /150 and 50/215. as you will read later this makes a massive difference to the comfort, support and durability

N.B. if a company does not quote the specification of foam used in a cot mattress, odds- on will be the lowest used to pass the British Standards and it certainly will not last five years as a cot bed mattress

 The Cot Mattress Pocket Springs

By taking out 60% of the foam and replacing it with a sprung core you will reduce the heat in your mattress significantly. Foam is an insulator and air will flow through the springs. Pocket springs in a cot mattress will last longer than basic springs and be more comfortable for your baby as you baby gets heavier and more active. There are cheap pocket springs available linked only on the length and not by the length and width and they are cheaper but give poor support.

The springs in a sprung or pocket sprung cot mattress are 6 cm deep, to achieve the British Standards of a 10 cm deep mattress you add 2 cm of foam either side. N.B this is a  thin layer of foam!

As your baby gets heavier their extra weight will push down on the 2 cm layer of foam and bring the pocket springs into operation. This is where a higher quality foam is vital. At the cot mattress company we use 30/150 foam and 50/215 foam to cover our pocket springs.

As you are now becoming a cot mattress expert you can now see how using much higher quality foam will make a huge difference to the comfort, support and durability of your cot or cot bed mattress

Fibre Cot Mattresses

Points for - Fibre cot mattress are inexpensive compared to foam. They can be made from recycled plastic bottles (great for the environment) Fibre does not have the same initial chemical smell like foam and consequently does not need airing for a day or two before use. Fibre is also cooler than foam.

Points against - Most fibre it is not as supportive as even the average grade of foam, It is certainly not as durable, it may be fine for cot mattress for temporary use at the grandparents house or for filling pillows. We have examined all fibre cot mattresses sold to date and they are really poor.

However there is a new firmer more durable fibre we are currently testing,  So far we are very impressed, should be on sale by mid March 2019  . It will be more durable and supportive and we will make it as comfortable as foam buy putting in pocket springs and a lambswool layer each side.

So those customers that wish to consider recycling and the future of the planet have an opportunity to buy a very good quality  cot mattress made  in part from recycled plastic bottles.

Looking after the environment

5 years ago we switched from dispatching our cot mattresses in heavy duty plastic bags to recyclable cardboard boxes. As we have mentioned are currently designing a top quality cot mattress using a very high grade fibre made from recycled plastic bottles. We are the first company in the UK to have developed and used natural pocket springs (no metal) in a natural cot mattress.

Natural Cot Mattresses

The cores are are mostly made from coir and lambswool, sometimes coir lambswool and springs. Their attraction is they are petro-chemical free and generally firmer than 28 weight foam and more durable. A problem occurs if you wish you keep to the all natural format when it comes to the covers. No natural fabric is totally waterproof so a cotton cover will not protect your cot mattress core. However there are other options available on our web site.

Cot Mattress Covers

Ensure these are breathable, easily removed for machine washing and give waterproof protection to the core that is a basic requirement. Extra quality covers give more comfort, temperature control, and a big plus is if they are of the Easychange® design:- A protective base cover with zip on Easychange® toppers (you always get two toppers one for the wash)
