Which cot mattresses is best for your baby?

A cot mattress needs to comfortable, supportive and durable and retain its shape for 5 years for a cot bed and 2 years for a cot. It has to provide protection against body fluids. To keep your cot mattress hygienic the covers bust be breathable and washable. A spare cover (one for the wash is a big plus)

The Cot Mattress Core

Your cot mattress will be either:- Foam, Fibre, Springs, Pocket Springs, coir Lambswool or Latex or a combination of one or two or three of these components


Over 90% of all cot mattresses have a foam content. Foam is the key component of a cot mattress and comes in a vast selection of qualities.To understand what you are buying it is worthwhile to know how foam is classified. Not that complicated.... honestly!

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

You may also see 24/130 foam classed as CMHR28, Obviously as these numbers increase you will get a higher quality foam that 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. Our Nightynite® cot mattresses use.a much higher quality foam than 24/130.

N.B. if a company does not quote the specification of foam used in a cot mattress odd on will be the lowest used to pass the British Standards and it certainly will not last 5 years in a cot bed mattress

Pocket Springs

By taking out 60% of the foam in a cot mattress and replacing it with a sprung core you will reduce the heat in your cot 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 it 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 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

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 - Fibre it is not as supportive as even the average grade of foam, It is certainly not as durable, it may be fine for temporary use at the grandparents house. Having said that there is a new firmer more durable fibre we are currently testing, It will be more durable and supportive but not as comfortable as foam, however our team are currently looking at ways to rectify this - watch this space, perhaps by January 2019 we would have a pocket spring fibre cot mattress that would merit our NightyNite&reg brand.

Looking after the environment

5 years ago we switched from dispatching our cot mattresses in heavy duty plastic bags to recyclable cardboard boxes. We are currently designing a cot mattress using fibre made from recycled plastic bottles. We are the only company in the UK to have developed and use natural pocket springs 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)
