A complete guide to memory foam
What is memory foam?
Memory foam is a specialist type of polyurethane foam that moulds in response to heat. It is most frequently found in mattresses where body heat helps the foam adjust to the shape of the user. Memory foam gets its name from its ability to transform back into its original shape when not in use.

What is memory foam made of?
Memory foam is a polyurethane foam that has undergone specialist processing. Polyurethane foam is treated with additives that generate the unique properties memory foam is known for. These additives evolve the polyurethane foam from its standard form to a type of foam that has viscoelastic properties. This is what gives memory foam its ‘memory’ features.
The properties of memory foam can be altered by using different levels of additives and chemical treatments.
Pros and cons of memory foam
Memory foam is known for retaining its shape and as a result, tends not to sag with repeated use. It also helps to prevent motion transfer, and is therefore useful in seating and as a mattress material as it prevents another user from being disturbed. Likewise, it is a naturally hypoallergenic foam which is great for allergy sufferers.
Some well known disadvantages of memory foam are that it tends to be more expensive than standard polyurethane foam. It is also a heavy material, so therefore difficult to transport when ordered in larger pieces. What’s more is that some users do report concerns of the strange odour that memory foam holds when new, but this usually fades over time.
Memory foam vs regular foam
When comparing the two, polyurethane foam is available in a range of thicknesses and densities, and is very easy to maintain. It is also cooler than memory foam. However, it is not as durable or comfortable, and doesn’t do much to stop motion transfer.
On the other hand, memory foam usually offers greater support but some users complain of feeling too hot when in contact with it. Memory foam does, however, offer targeted pressure relief and tends to last for much longer.
Is memory foam good for your bed?
Memory foam mattresses mould to the body and evenly distribute body weight, therefore, they are great for relieving pressure on the joints and spine.
How to check if memory foam is of good quality?
The quality of memory foam can be determined by its thickness, density, feel of its cover material and its certifications, such as the safety labels it holds. If brought from a specialist manufacturer or brand name, quality is often guaranteed. For the most part, quality is determined by the individual user – it’s all down to personal preference. Some find memory foam very comfortable, and others don’t.
Is memory foam toxic for humans?
Some memory foams may contain isocyanates which are considered toxic. However, such chemicals do not pose a risk to humans when the memory foam product has been responsibly manufactured by a reputable company. Memory foam is safe for everyday use and does not cause health issues like cancer.
