Everything you need to know about foam mattresses
Choosing a mattress involves understanding the different technologies available on the market, including foam mattresses .
Along with latex and innerspring mattresses, foam mattresses are one of the main types of mattresses. If you have questions about foam mattresses, you've come to the right place: we'll guide you in choosing the ideal mattress that meets your needs.

What is a foam mattress?
Foam mattresses are a technology that is suited to the morphology of many sleepers, especially when you opt for high-quality foam in terms of density and thickness. This material, popular in bedding, offers a softness that ensures sleeping comfort, guaranteeing soft and restful nights. High-density and memory foam mattresses (which are the only foam qualities offered by Morphéa) have the advantage of providing exceptional support. Enveloping, with support that perfectly distributes pressure points, they are recommended for people with muscle pain, joint pain, or back pain. Perfect for any type of sleep: on your back, side, or stomach.
They are also recommended for small sizes (less than 70 kg).

The different types of foams
We have selected the best foams to offer each sleeper a tailor-made comfort, capable of adapting to morphology, body heat and natural sleep movements.
- High-resilience foam (HR 35 kg/m³): this is the foundation of our mattresses. Its high density guarantees firm and lasting support while keeping the spine properly aligned. Thanks to its open-cell structure, it also promotes excellent air circulation and resistance to sagging over time.
-
Air Memory® memory foam: a true MORPHEA signature, this foam, also known as “viscoelastic,” naturally conforms to the body's curves and relieves pressure points. It provides enveloping comfort while maintaining good breathability, for restful and restorative nights.
- ErgoFeel® foam: more responsive, it adapts to every movement without creating tension. It enhances the progressive support of the mattress and ensures balanced comfort.
Each layer has its role: welcoming, supporting, balancing and durability, for comfort that remains as pleasant over the years as on the first day.

How do I choose my foam mattress?
Choosing the right foam mattress involves answering various questions related to your body type, any back problems you may have, and the quality of the foam. Below are some tips to consider when choosing your foam mattress.
1. A minimum density of 25 kg/m³ is recommended!
To guarantee lasting comfort, it is essential that the mattress foam has a density greater than 25 kg/m³. Depending on your personal preferences and body type, your comfort level may vary with a foam of varying density. Generally, the higher the density of your mattress foam, the more comfortable you will feel. Conversely, a foam mattress with a density lower than 25 kg/m³ will only be a very temporary sleep companion, as the foam is likely to sag quickly. That's why at MORPHEA , we have chosen to offer you quality mattresses that meet these needs.
2. Memory foam as your best ally
Memory foam, also known as viscoelastic foam, is a truly remarkable technology. This recent innovation is composed of microcells that closely conform to the curves of your body. Thanks to its high density, it helps reduce pressure points and promote optimal blood circulation. Particularly appreciated by sleepers seeking a cozy, cocooning experience, a memory foam mattress offers exceptional, enveloping comfort. Temperature-sensitive, this foam gradually softens to adapt to your body shape, automatically returning to its original form with each change of position. Furthermore, if you share the bed with another person, their movements will no longer disturb you. Memory foam ensures perfect motion isolation.
3. Opt for as many support areas as possible
Foam mattresses typically have multiple support zones. This means that the support is differentiated according to different parts of the body. If you suffer from pain while sleeping, this type of mattress is particularly beneficial. The zones provide targeted support for different parts of the body.
Here's what you can find on the market:
- 3 support zones
- 5 support zones
- 7 support zones
The more support zones there are, the more precise and optimal the support will be.
At MORPHEA all our foam mattresses benefit from 7 support zones (head, shoulders, lumbar, pelvis, thighs, calves and feet) in order to provide you with maximum comfort, even on our economical foam mattresses .
4. A good mattress thickness
The thickness directly influences the initial feel and the durability of your mattress. The thicker the mattress, the more technical layers it contains, delivering premium comfort.
- Between 22 and 25 cm : ideal for everyday use, with very well-balanced comfort and good support.
- Between 26 and 30 cm : “hotel-style” comfort thanks to several layers of foam, the mattress remains stable and soft at the same time.
- Above 30 cm : the thickness of a high-end mattress with precise support, enveloping comfort and exceptional durability.
4. Choose the right size foam mattress
If you sleep alone: a 90×190 cm mattress is sufficient for a compact bed, but a 120×190 cm or 140×190 cm offers more freedom of movement and better everyday comfort.
If you sleep as a couple: opt for a 160×200 cm (Queen Size) or 180×200 cm (King Size) bed. These sizes improve sleeping independence, reduce nighttime awakenings, and minimize the feeling of discomfort associated with a lack of space.
5. Adapt your mattress to your bed base
To fully enjoy the benefits of your foam mattress, be sure to pair it with a compatible bed base :
- The slatted bed base promotes breathability and stable support, ideal for high-resilience foams.
- The upholstered bed base provides a slight softness while ensuring the stability of the bed.
- The Morphea storage bed combines storage, support, and optimal comfort.
A good mattress and bed base combination significantly improves the quality of your sleep and extends the lifespan of your bedding.
FAQ - Foam mattress
Is it recommended to sleep on a foam mattress?
Yes, especially when it comes to high-resilience or memory foam. These foams offer excellent back support, good pressure point distribution, and adapt to all sleeping positions. Morphea models combine comfort, support, and breathability for a restful and restorative sleep.
What type of foam mattress is best?
The best foam mattress depends first and foremost on your preferences and body type. Memory foams are known for their enveloping comfort and their ability to relieve pressure points. At MORPHEA, we combine them with other materials for even more complete comfort. For example, the VICTORIA mattress combines memory foam and pocket springs for precise support and excellent motion isolation. It was even voted Product of the Year 2025, proof of its universal comfort and recognized quality.
Does a foam mattress solve the problem of back pain?
Although there are several foam mattress models available, not all of them are necessarily suitable for back pain. In fact, foam mattresses can only be beneficial for the back if they meet certain comfort criteria.
For example, memory foam mattresses are particularly recommended for relieving back pain. This technology has the ability to adapt to the shape of your body, thus evenly distributing pressure points. Sensitive areas such as the shoulders and pelvis benefit from optimal support. Memory foam offers personalized comfort adapted to your anatomy.
In conclusion, our foam mattresses address back pain problems because they all have memory foam.
What are the disadvantages of sleeping on a foam mattress?
A low-density foam mattress may sag over time or retain heat.
To avoid this, choose high resilience foam (≥ 35 kg/m³) and good ventilation.
The Air Memory® and ErgoFeel® foams used by Morphea are designed to remain stable, breathable and durable, without these drawbacks.
Why is my foam mattress sagging?
Premature sagging often results from insufficient density or an unsuitable bed base. Morphea high-resilience foams retain their shape for up to 10 years. To extend their lifespan, remember to rotate the mattress regularly and pair it with a slatted or upholstered bed base in good condition.
How long will my foam mattress last?
The lifespan of a mattress depends largely on the quality of the materials used. For foam mattresses, especially memory foam mattresses, lifespan is generally calculated based on the number of hours of sleep. A mattress is considered durable when it has been used for approximately 29,600 hours, which is equivalent to 10 years of daily use.
On average, quality memory foam mattresses can last between 8 and 10 years. Mattresses with a higher density are generally more durable. That's why all our foam mattresses have a high-density foam of 35kg/m3 to improve their durability.
In addition, at MORPHEA, we offer you a guarantee of up to 10 years and a 100-day trial of our mattresses , to ensure optimal quality of our mattresses.
How do I care for my foam mattress?
Caring for a foam mattress is similar to caring for a traditional mattress. You can easily clean it in just a few steps:
- Remove stains with soapy water: Use soapy water to remove stains from your foam mattress.
- Using Sommières clay dry: Sommières clay can be used dry to detach the entire surface of the mattress.
- Clean with a mixture of white vinegar, warm water and dish soap: Prepare a mixture of white vinegar, warm water and dish soap to clean your entire mattress.
- Eliminating bad odors with baking soda: Use baking soda to absorb bad odors from your mattress.
