What type of mattress should you choose? The guide to finding the one that's right for you.

Buying a mattress is often a decision we put off, due to lack of time, fear of making the wrong choice... or because everything looks the same at first glance.

Yet, the mattress you sleep on influences much more than just your nights. It affects your energy when you wake up, how your body recovers, and that quiet comfort that makes the difference between "I slept" and "I slept really well."

Given the diversity of available technologies, it's normal to hesitate. Foam, memory foam, pocket springs, latex, hybrid: each type of mattress meets different needs.

Which one is best suited to your body type? To your sleeping position? To your expectations in terms of comfort or support?

In this guide, we compare the main types of mattresses, their differences, and the profiles they best suit, to help you make a clearer, more confident, and more appropriate choice for your sleep.

To refine your choice, compare Morphea mattresses based on your desired comfort and sleeping position.

In summary:

• The right type of mattress largely depends on your sleep profile and desired comfort.
• The main mattress technologies to be aware of are foam, memory foam, pocket springs, latex, and hybrid.
• If you sleep with a partner, sleeping independence and mattress width become essential.
• For back pain, a mattress offering firm, stable, and well-distributed support, without excessive rigidity, is generally sought after.
• If you are looking for a very comprehensive compromise between support, comfort, breathability, and durability, a hybrid mattress is one of the most versatile options.

The main types of mattresses to know

Foam mattress

A foam mattress is often appreciated for its simplicity and affordability.

It can be suitable for a tight budget, a guest room, occasional sleeping, or for some solo sleepers who like a more uniform feel. However, not all foam mattresses are equal. Their quality depends heavily on the density of the foam, the internal structure, and the level of finish.

Key takeaways:

• rather uniform feel
• accessible solution depending on the model
• attention to density and longevity

Memory foam mattress

Memory foam is appreciated for its ability to conform to the body's contours.

It provides a more enveloping feel and helps to better distribute pressure points, particularly at the shoulders and hips. This type of comfort often appeals to sleepers who seek a more cocoon-like sensation, especially when sleeping on their side. On the other hand, a very prominent memory foam can give a warmer or more pronounced sensation depending on the individual.

Key takeaways

• enveloping feel
• good pressure relief
• caution if you are sensitive to heat

Pocket spring mattress

A pocket spring mattress is one of the most interesting technologies for daily use.

Each spring works independently, which promotes better ventilation, good stability, and sleeping independence often appreciated by couples. This more aerated structure also explains why pocket springs are frequently recommended for sleepers who tend to get hot.

Key takeaways

• very good ventilation potential
• interesting for couples
• more dynamic support

Latex mattress

Latex appeals with its reactive comfort, elasticity, and good air circulation.

It can suit sleepers who are looking for support that is both soft and tonic, without a too-stuck sensation. Its feel is quite specific, however, making it a technology to try if you are hesitating between several sleeping sensations.

Key takeaways

• reactive comfort
• good ventilation
• specific feel, to be appreciated according to preference

Hybrid mattress

A hybrid mattress typically combines a pocket spring base with several layers of foam, sometimes memory foam.

Today, it is one of the most complete constructions for daily use, as it allows combining several benefits in a single mattress: support, comfort, sleeping independence, breathability, and durability.

At Morphea, this is often the type of mattress we recommend to sleepers who want premium, versatile, and easy-to-live-with comfort on a daily basis.

Key takeaways

• very good overall compromise
• interesting for daily use
• often higher budget

Foam or spring mattress: which to choose?

This is one of the most frequent comparisons when choosing a mattress.

A foam mattress can be suitable if you are looking for a simpler, more uniform, or more affordable sleeping solution. It can also be relevant if you prefer a more cushioned feel. However, its quality strongly depends on the foam density and the overall design of the mattress.

A pocket spring mattress is often preferred for daily use, especially if you sleep with a partner, if you need more breathability, or if you appreciate more dynamic support. Individual springs also help to better distribute movements during the night.

In practice, foam can be a good option for certain uses or profiles, while pocket springs often provide a more aerated and versatile base for a primary sleeping solution.

Comparison of mattress technologies

Key technical benchmarks to remember

To choose the right mattress, a few simple benchmarks can make all the difference:

• The core of the mattress corresponds to the heart of the structure. It determines most of the support.
• The filling mainly influences the feel, meaning the sensation you get from the first few minutes.
• Density is particularly important for foam durability over time.
• Motion isolation becomes a central criterion if you sleep with a partner.
• Comfort zones can be useful when pressure points are pronounced or body types differ. 

What type of mattress should you choose based on your profile? 

The choice of mattress type depends not only on the technology, but also on your sleeping profile and your actual needs during the night.

You sleep alone

If you sleep alone, the choice is generally simpler. You can prioritize your personal comfort sensation: more enveloping, firmer, softer, or more dynamic.

In this case, a quality foam mattress, latex, or a hybrid can be very suitable. It will mainly depend on your budget, your body type, and your sensitivity to pressure points.

You sleep with a partner

Sleeping with a partner significantly changes priorities.

You need to consider motion isolation, meaning the mattress's ability to absorb the other person's movements, as well as the bed's width. In France, 140 x 190 cm remains a standard size for two people. But a 160 x 200 cm, or even a 180 x 200 cm, often provides a real gain in comfort, especially when sleep rhythms or body types differ.

For couples, pocket spring mattresses and hybrid mattresses are often the most interesting, as they combine stability, breathability, and good motion isolation.

If you sleep with a partner with different body types or sleep habits, our guide "Which mattress to choose for a couple?" will help you refine your choice.

You have a small body type

If you are rather light, a mattress that is too firm can create unnecessary pressure points, especially at the shoulders and hips.

In this case, we often recommend:

• a mattress with a softer feel
• a well-balanced memory foam
• a hybrid with progressive comfort

The idea is not to sink in, but to allow the mattress to conform to the body's shapes to a certain extent.

You have an average body type

Most technologies can be suitable, provided they are well-designed.

What you need is a good balance between support and comfort. This is often where hybrids and pocket springs stand out: they offer a more universal feel, easier to love on a daily basis.

You have a large body type

If you have a larger body type, the main concern is not just softness, but the mattress's ability to remain stable over time.

A mattress that is too soft or insufficiently structured may sag more quickly. For this profile, thickness and density become particularly important criteria. Generally, foam or latex models should offer at least 20 cm of thickness, and spring models more than 25 cm, to provide more stable support over time.

We then recommend: 

• a good quality pocket spring mattress
• a well-structured hybrid mattress
• a firm or balanced firm feel

The goal is to have stable support, without a sinking feeling.

Your body type differs from your partner's

If you don't have the same body type, you need a mattress capable of handling different pressure points without creating hollows or discomfort. The objective is to maintain stable sleeping surface while offering good motion isolation.

Recommended:

• hybrid mattress (balance of support + comfort for two profiles)
• mattress with comfort zones (better distributed support according to body areas)

You have a sensitive back

For sleepers with sensitive backs, a firm to very firm mattress is often preferred.

But firmness alone is not enough. What's needed is consistent support, capable of keeping the spine well-aligned while limiting pressure points. 

In practice, hybrid mattresses and pocket springs with well-designed comfort layers are often the most reassuring for various back pains.

You tend to get hot 

If you are sensitive to heat, avoid mattresses that are too enclosed or too enveloping. 

Pocket springs are among the most breathable technologies, thanks to their more airy structure. Latex can also be appreciated for its good air circulation. Memory foam, on the other hand, often provides more envelopment, which may appeal to some sleepers but be less suitable for those who tend to get hot.

What mattress to choose based on your sleeping position?

The position in which you sleep directly influences the type of support and feel to prioritize. A mattress adapted to your sleeping position helps to better distribute pressure points and maintain proper body alignment during the night.

If you sleep on your side

Side sleepers generally need a softer feel at the shoulders and hips to avoid pressure points. A mattress that is too firm can create tension, especially if you have a light body type. Mattresses with memory foam, well-balanced hybrids, or certain latex mattresses can be particularly suitable.

If you sleep on your back

Sleeping on your back requires uniform support, capable of properly maintaining the lumbar area without allowing the pelvis to sink. A balanced to firm, well-structured mattress is often the most suitable. Pocket springs and hybrids generally meet this need well.

If you sleep on your stomach

Sleeping on your stomach requires more vigilance, as a mattress that is too soft can accentuate the arch of the lower back. It is better to favor firmer support, with a stable structure and little sagging.

If you change position often

If you move a lot during the night, choose a mattress that remains comfortable in multiple positions. Hybrid mattresses and pocket springs are often the most versatile in this regard.

What mattress firmness to choose?

To properly choose the firmness of a mattress, it is necessary to distinguish three concepts: feel, support, and overall firmness.

This is probably the most confusing point in choosing a mattress.

A mattress can offer a soft feel on the surface while maintaining firm support in depth. 

It is precisely the balance of these three concepts that allows for reconciling immediate comfort and proper spinal alignment.

The feel

This is the immediate sensation when you lie down. It can be soft, balanced, or firmer.

The support

This is the mattress's ability to keep your body in proper alignment during the night.

Overall firmness

This is the overall feeling, which depends on both the core of the mattress and the comfort layers.

In other words, a mattress can have a soft feel while offering firm support. This is often what we look for: surface comfort, but deep stability. 

What mattress size to choose?

Mattress size greatly impacts sleep quality, especially if there are two of you.

In France, the most common dimensions are:

• 90 x 190 cm for one person
• 90 x 200 cm for a tall person
• 140 x 190 cm for two people
• 160 x 200 cm for couples who want more comfort
• 180 x 200 cm for very spacious comfort
• 200 x 200 cm for the highest level of comfort 

In practice, the mattress should exceed the sleeper's height by about 10 to 20 cm to offer real sleeping comfort, especially for the legs and freedom of movement.

For a couple, 160 x 200 cm often represents the best compromise. It allows for better sleep without disturbing each other, without necessarily moving to an XXL size immediately.

If you are hesitating between several dimensions, also consult our dedicated guide on what mattress size to choose according to your space and sleeping profile.

What mattress thickness to choose?

Thickness isn't everything, but it gives a good indication of the mattress's level of structure and comfort.

As a guide:

• less than 20 cm: rather for occasional use, an extra bed, or fairly simple models
• between 20 and 25 cm: very good comfort for daily use
• 25 cm and more: more generosity, often more comfort and stability depending on the design

What should be remembered is that a good thickness is only valuable if the materials and structure follow suit.

Which bed base to choose for your mattress?

The mattress never works alone: the bed base directly contributes to the comfort, ventilation, and durability of the bedding.

The choice of mattress also depends on the type of bed base. A slatted bed base offers firm and regular support, and is suitable for all types of mattresses. A spring bed base is mainly recommended with a spring mattress. Adjustable bed bases are better paired with foam or latex mattresses.

In practice:

• slatted bed base: the most versatile
• spring bed base: particularly relevant with a spring mattress
• adjustable bed base: to be checked according to the mattress technology

Even a very good mattress cannot offer optimal comfort on a worn or unsuitable bed base.

How to recognize a good quality mattress?

A good mattress is not judged solely by its technology or its advertised firmness level. 

Here are the most important points:

1. Support adapted to your body type

The primary criterion remains the quality of support. The mattress must keep the spine in a natural alignment, without pelvic sagging or excessive tension in the shoulders. 

2. Quality of materials and construction

A good quality mattress relies on sufficiently dense materials and a stable structure over time. For daily adult use, polyurethane or high-resilience foam around 35 kg/m³ or more, memory foam from 50 kg/m³, and latex generally above 65 kg/m³ can be considered benchmarks. For a pocket spring mattress in 140 x 190 cm, a suspension with around 600 to 800 springs provides a consistent base, with 700 springs or more often being more reassuring. However, these figures remain guidelines: the actual quality also depends on the assembly, comfort layers, support zones, and stability over time.

3. Motion isolation

The mattress must limit the transmission of movements. This is a central criterion for preserving sleep quality when sleep rhythms or body types differ. Pocket springs and hybrid constructions are often the most relevant in this regard.

4. Breathability

A quality mattress must also manage internal ventilation well. This is particularly important for sleepers who get hot, for poorly ventilated bedrooms, or for daily use by two people.

5. Durability over time

The comfort of the first few nights is not enough. A good mattress must maintain its support, stability, and consistent feel over time.

6. Trial conditions

A home trial period is a real plus, as a few minutes lying in a store are not always enough.

At Morphea, we believe that a good mattress must combine three essential qualities: fair support, a well-balanced feel, and a design built to last. It is this balance that provides truly reliable comfort, night after night.

How to test a mattress without making a mistake?

Trying a mattress is not just sitting on it for ten seconds.

To judge properly:

• lie down in your usual position
• stay for a few minutes, not just a few seconds
• check if your shoulders, pelvis, and back are well supported
• if you sleep with a partner, test it together
• ask yourself if you feel supported, not just welcomed

This is why home trial periods are so important: the real test is your actual sleep, not a quick impression.

What mattress to choose based on your priority?

If your priority is price or occasional use, a well-designed foam mattress may suffice.

If you are looking for a more enveloping feel and better pressure point reduction, a memory foam mattress may be relevant.

If you sleep with a partner, move a lot at night, or tend to get hot, pocket springs often form a very interesting base.

If you are looking for more responsive and well-ventilated comfort, latex can be a good option.

Finally, if you are looking for the most complete compromise between support, feel, motion isolation, and versatility, the hybrid mattress often remains the most balanced choice for daily use.

The essential thing, therefore, is not to seek the best technology in absolute terms, but the one that best suits your body type, your sleeping position, and your desired comfort.
