What is a memory foam mattress? We tell you everything

Initially designed to absorb the shocks of NASA astronauts taking off, the foam that makes up a memory foam mattress has gradually established itself as the unavoidable star in terms of bedding . Bdreams explains what a memory foam mattress is and its advantages!

Memory foam mattress: Definition

Thememory foam mattress is currently very popular and is one of the latest innovations in terms of bedding comfort . But what is the shape memory effect ? It is made possible thanks to a material, a viscoelastic and thermosensitive foam, which reacts to the heat of your body to soften and adapt to your morphology. This memory foam layer is usually located on both sides of a reversible mattress (but this is not always the case, so check this before buying). A memory foam mattress can be more or less thick and dense depending on the model, but it is in any case designed to follow the contours of your body and return to its initial shape at the slightest change in position when you sleep. It is therefore a material that constantly adapts to new positions to give you the impression of being enveloped during your sleep! There are memory foam mattresses with springs, latex or even foam .

The difference between a memory foam mattress and a traditional mattress

There are two main points that differentiate a memory foam mattress from a conventional mattress . For starters, memory foam models are sensitive to the temperature of the room: the foam can therefore soften or harden depending on the temperature of the surrounding air. On the other hand, the memory foam complicates the ventilation between the layers of the mattress, so the ventilation is not optimal for people who sweat a lot during their sleep.

The benefits of a memory foam mattress

A relaxing and restorative sleep

The memory foam mattress promotes the propagation of heat over the integrity of the surface to facilitate falling asleep. It offers a high level of relaxation thanks to its comfortable and flexible material . In addition, by marrying your morphology, it allows you to relax better for a deep and restorative sleep every time. Combine it with a pillow and a mattress topper , both shape memory for even greater comfort! You will wake up less tired in the morning thanks to better sleep cycles.

A good distribution of support points

A memory foam mattress offers a better distribution of support during sleep: when you change position, you don't wake up in the middle of the night. This type of mattress reduces the pressure points that cause unwanted awakenings. It also relieves back, joint and neck pain thanks to better body alignment : it reacts to movement to keep your spine straight. Moreover, many health professionals such as orthopedists recommend the use of a memory foam mattress to prevent joint and low back pain!

The independence of the beds

In the double beds, a shape memory mattress absorbs the movements of the partner when he sleeps, which allows you to enjoy a better quality of sleep. Each sleeper can therefore enjoy their sleeping area without being disturbed by the movements of their partner, even on one and the same mattress!

Ideal for allergy sufferers

The memory foam mattress is both hypoallergenic, anti-mite and antibacterial ! It's a perfect mattress for allergy sufferers, as it's treated to stay as healthy as possible and help you get better nights. It is suitable for both children and people prone to respiratory diseases thanks to its polyurethane foam which provides elasticity and ensures good air ventilation.


The shape memory mattress is therefore designed from materials that adapt to the morphology of your body and return to their initial position as soon as you change position. This type of model offers multiple advantages, both for the quality of your sleep and for your health. If you have any questions, do not hesitate to contact our Bdreams team !
