Natural latex tree and oil drill compared.


Which is more suitable for you, a natural latex mattress or a polyurethane or a memory foam mattress?

This question is fundamental for anyone thinking of buying a mattress.

I will pull back the curtain for you and explain the differences between these foams so that you can make an informed choice when investing in your sleep quality.


A memory or polyurethane mattress is also known as polyfoam.

Polyurethane mattresses are the most common type of mattresses. Sometimes Polyurethane foam can be used as a top comfort layer in innerspring or pocket coil mattresses.

However, a large block of the foam can be utilised by itself as a PU foam mattress. 

You may be questioning, what is the difference between polyurethane and memory foam?

Well, in terms of texture, they are quite different. But, they both have polyurethane in them though.

The principal distinction among polyurethane foam and memory foam is that memory foam includes added chemicals which boost its density and viscosity.

Both foams are chemically related but feel tremendously diverse to each other. PU foam is a lot more springy than memory foam, and memory foam creates a ‘trapped’ or ‘sinking’ feeling to pressure.

Polyurethane foam is entirely synthetically. There is no such thing as a ‘natural’ PU mattress, in contrast to latex which usually is all-natural.

There are different grades of polyurethane foam mattresses:

  1. Regular Foam – not suitable for the whole mattress; typically middle layer
  2. High Density Foam – not ideal for the entire mattress; typically base layer
  3. High Resiliency Foam – more expensive layer. It is treated somewhat differently from the other two grades and attains much higher support.
  4. High Resiliency PU Foam – very costly and therefore not willingly used. If you are looking at a polyurethane foam mattress, it is wise to believe that it is one of the lower grades unless it is precisely.


A latex mattress is a natural product. Natural latex comes from the rubber tree (Hevea brasiliensis).

This tree produces a milky sap which is harvested and prepared into moulds of latex foam.

Natural latex has built-in springy properties, so latex mattresses do not need for any springs, coils, or toxic synthetic chemicals. 


There is a massive demand for latex mattresses because of its known comfort and supportive qualities.

If you were to lie on a latex mattress, you would observe a luxurious softness that allows you to sink in, accompanied by a firmness which supports you entirely in cloud-like comfort.

Yet, there is more to why a latex mattress is a great choice other than comfort.

However, comfort should always be your number one priority you are seeking in a great mattress.

Latex mattresses have outstanding airflow qualities, perfect for people who don’t want to sleep hot. Latex also is intrinsically mold and dust mite resistant. 


  • Unprecedented comfort – latex mattresses offer exceptional comfort. We had many patients tell us that their latex mattresses may have alleviated their pain. 
  • Excellent support for your body – latex surpasses at adequately supporting the body and spine. Many chiropractors or osteopaths suggest latex mattresses for this reason.
  • Naturally sourced product – latex comes from nature, unlike chemically processed polyurethane. Being a natural product makes latex especially attractive to those with environmental interests or for those who want to evade contact with toxic chemicals.
  • Excellent ventilation – latex has a natural open cell construction which allows excellent airflow. Moreover, latex mattresses contain perforations produced during the processing phase, which improves the airflow even farther. 
  • Soft movement – movement on one side of a latex mattress will not be observed easily on the opposite side.
  • Naturally resistant to dust mites and mould – latex offers natural protection to these, without the use of toxic chemicals.
  • Long-lasting – a latex mattress is highly impervious, enduring other types of mattresses. 


Relatively inexpensive – especially in the case of the lower grades of polyurethane mattresses. Low-cost chemical processing is a cheap way to make a mattress. If you are looking for just a mattress at a lower price and you are not too worried about any of the mentioned possible concerns, then a PU or memory foam mattress should fit your need.

Lightweight – a polyurethane mattress is one of the easiest to move or flip. These type of mattresses can easily fit into a small box for shipping. 


  • Poor support for spine or pressure points – polyurethane foam does not support the body or spine properly. 
  • Not exceptionally comfortable – a polyurethane mattress may not feel particularly suitable. If you want a PU mattress, the high resiliency grade is your best choice. However, a high resiliency grade PU foam does not even resemble the comfort of a natural latex mattress.
  • Too Much Movement  – the very ‘springy’ nature of polyurethane foam means that any movement is conveyed throughout the entire mattress.
  • Poorly ventilated – unlike latex, there is little to no airflow in a polyurethane mattress. PU and memory foams may tend to off-gas toxic VOC fumes as well.
  • Short lifetime – polyurethane foam breaks down quickly. It will need to be renewed much sooner than a latex mattress.


Natural latex mattresses are incomparably better in many different ways to polyurethane mattresses.

Natural latex allows a lot of advantages beyond its exceptional comfort.

The superior airflow makes it perfect for those who don’t want to sleep hot, and its natural mould and dust mite resistance are further benefits.

Rest assured that the slightly higher cost of a latex mattress is offset by its much longer lifetime.

Natural latex comes from tree sap, and it is not petro-chemicals. To put things in perspective, it takes roughly of 20 acres of trees to make a single queen-sized mattress (we don’t hurt the trees in the process! We only use the tree sap like maple syrup ). Lastly, the essential factor is that you get a comfortable night’s sleep, and you can’t put a price on that!
