What is inside a cold foam mattress?
There are various types of cold foam mattresses available.
A few of them are made of pure cold foam and don’t have any other foam types.
Others combine a few different foam layers, such as memory foam, gel foam, or latex foam.
The zones of a cold foam mattress
A few cold foam mattresses are divided into comfort zones.
These zones help give the body the support it needs, aid comfort, and ease any tension on the back.
Separate zones correspond to and support different pressure spots.
Your body ought to be aligned throughout your sleep.
For this, you need to sink into the mattress deeper at some key areas and less at others.
This ensures maximum comfort and is especially important for side sleepers.
Mattresses usually have 3, 5, 7, or 9 comfort zones.
Zones are usually placed in the abdomen, back, skull, and foot areas.
The zone number will always be odd.
This is because of the mattress's mirror image structure, ensuring that your body is always supported perfectly, no matter how or in what position you lie in.
What to look for in a cold foam mattress
When searching for a cold foam mattress, you need to keep in mind that not all cold foam mattresses are good.
There are some low-quality, uncomfortable options out there as well.
Consider the following.
1. Foam density
Density is a good indicator of quality.
The density of a mattress refers to the quantity of polyurethane that has been converted into foam to produce one cubic metre.
Generally, higher-density mattresses are of better quality.
Always look for a high-density polyurethane foam mattress.
You can use the below table as a rough guide.
|Density in kg/m³||Expected lifespan|
|Up to 25||Up to 2 years|
|30||Up to 3 years|
|35||5 - 6 years|
|40||6 - 8 years|
|50 - 60||10 years and more|
2. Delivery options and return period
To enjoy a hassle-free purchase without risks, ascertain that the seller provides the following:
- Free delivery.
- No-strings-attached trial period.
- Free returns.
A generally stipulated trial period for most brands is between 30 - 100 days, but some brands provide a more extended period.
It usually takes a few weeks for the body to adapt to a new mattress. So, you should have enough time to assess the bed.
An extended trial period helps you judge the mattress better.
If at any point during the trial period you feel that the mattress is not a good fit, you can return it free of charge for a full refund.
3. Mattress rebound rate
The mattress rebound rate refers to how fast the mattress returns to its initial form after being compressed.
The greater the rebound rate, the faster it’ll return to its original shape.
The rebound rate is a good indicator of whether the mattress will fit heavyweight people and restless sleepers.
It also indicates whether the mattress is susceptible to dents.
You should always be able to move around freely on a mattress while receiving adequate support and stability.
Finding the right bed frame
You should select the right slatted bed frame to enhance the benefits of your cold foam mattress.
Here are some factors to consider.
We would advise that you buy a slatted frame with similar divisions as the comfort zones in your cold foam mattress.
For example, if you have a 7-zone cold foam mattress, you should also buy a 7-zone slatted frame.
Using a similar frame will increase comfort by helping your shoulders and abdomen sink in deeper, which keeps your body and spine in a straight alignment.
Slatted frames with adjustable height
Cold foam mattresses adapt very well, which is why we’d recommend choosing a slatted frame that’s height-adjustable.
Not only do adjustable head and foot sections increase overall comfort and stability, but they also help with blood flow and breathing.
This is especially important for seniors.
While a height-adjustable frame is preferable, cold foam mattresses can also be placed on rigid slats.
Make sure that the space between slats does not exceed 5 cm.
Alternatives to cold foam mattresses
Most mattresses have at least one layer of cold foam.
But if you don’t find pure cold foam mattresses comfortable, you may consider one of the following options instead.
Memory foam mattresses
Memory, or viscoelastic, foam shares many features with cold foam mattresses, but its memory imprint further characterises it.
As we increase pressure on the mattress, it softens and lets the body sink in.
The mattress takes the shape of the body, making sure it adapts perfectly and maximising comfort.
Memory foam mattresses also have excellent pressure relief abilities, making them useful for orthopaedic purposes.
Despite the comfort, the memory effect can cause difficulty when changing your position while lying down.
This makes memory foam mattresses unsuitable for restless sleepers.
Do you prefer firmer mattresses? Then an innerspring mattress may be more suitable for you - they provide a more stable and supportive feel.
The base is made of coils or springs, which can hold separate loads, enabling the mattress to adjust much better to the body and relieving pressure points.
Innerspring mattresses are also naturally ventilated as the spacing between the springs provides room for breathability.
Greater airflow allows for a cooler sleep.
Quality is critical in a spring mattress.
Low-quality spring mattresses tend to wear out quickly and form dents. This can cause - or worsen - back pain.
Higher-quality spring mattresses include pocket spring mattresses and barrel pocket spring mattresses.
Hybrid mattresses, which consist of springs and quality foam, are a good option as well.
Restless sleepers and those who like a cooler sleep can explore the latex mattress option.
They come with great features like flexibility, ventilation, and superior comfort.
Natural latex mattresses are also an organic option, making them a good match for people who prefer organic and environmentally-friendly products.
The only downside to latex mattresses is that they are heavy, more expensive, and require regular cleaning.
Gel foam mattresses
Gel foam mattresses offer good ventilation, comfort, and flexibility.
Gel foam is known for its snuggly feel and is common as the first comfort layer in mattresses that combine various foam layers.
