Customer Rating

Most people sleep on either their back or side.

Sleeping on your side has both advantages and disadvantages, on one hand, it decreases the probability of snoring, however, on the other hand, it increases the likelihood of back problems, pain in the neck or hip.

These problems can be avoided if you choose the correct mattress for side sleepers, choosing the mattress according to the position in which you sleep will improve your quality of sleep and your posture.

You can only have a healthy sleep if the quality of your bed is right, and if it fits your sleeping position. 

The 5 Best Mattresses For Side Sleepers

Here are the best mattresses for side sleepers:

A Detailed List of the Best Mattress For Side Sleepers

1. Emma Mattress - Best High Density Foam Mattress

Best High Density Foam Mattress
Emma mattress
Emma Mattress
  • Adapts to all body postures
  • Suitable for different weights
  • Quality materials
  • Greater freshness thanks to the open pores of its memory foam
  • It is not the best option for older people with little mobility.


  1. At 25 cm thick, the Emma mattress is made up of successive layers of Airgocell foam (4 cm), memory foam (4 cm) and a core of cold foam.
  2. The second layer is made of memory foam, with a memory effect that distributes pressure and adapts to the shape of the body.
  3. The layer of high-density cold foam that forms the core of the mattress gives it firmness to prevent you from sinking excessively and provides the necessary support to ensure the correct position of the back and neck.
  4. However, people who weigh more than 90 kg may consider it somewhat soft, especially if they are used to a spring mattress.
  5. The high porosity of its foams improves breathability, resulting in an incredibly cool mattress.
  6. One of the main strengths of the Emma mattress is that you can try it for 200 nights without obligation.

The EMMA stands out for its ability to adapt to most postures and body morphologies.

It is very breathable, cushions the movements of each user well and has the ideal intermediate hardness for couples.

Although you can alternate the head and feet, the mattress should always be placed with the same side up.

It also comes with a 10-year warranty. Remember that you should change your mattress every 10 years or so, so this guarantee ensures quality throughout its useful life.

2. Flex Nube Visco - Best Pocket Spring Mattress

Best Pocket Spring Mattress
Flex Nube Visco
  • Excellent durability
  • Pretty cool
  • Good bed independence
  • Anti-mite and anti-allergy treatment
  • It is heavy


  1. It Combines the characteristics of pocket spring mattresses, with its independence of beds and absorption of movement, and the adaptability and memory effect of memory foam, which provides comfort and a sense of welcome.
  2. Also, the gel particles it contains act as a thermoregulatory agent that absorbs heat, increasing the sensation of freshness, which is especially appreciated during the summer.
  3. Under the hood is a layer of hypoallergenic fabric designed for people with sensitive skin.
  4. In total, it is 31 cm thick and is a good option if you frequently change your position in bed, thanks to its good adaptability and the speed with which its materials adapt to changes in posture.

We also recommend that you turn it over every 3-4 months and rotate it a couple of times a year to extend its useful life and enjoy maximum comfort at all times.

3. Sonpura Gaudi- Best Multisac Micro Pocket Springs

Best Multisac Micro Pocket Springs
Sonpura Gaudi
  • Excellent durability
  • Pretty cool
  • Good bed independence
  • Anti-mite and anti-allergy treatment
  • It is heavy


  1. The core of pocket springs, developed with Multisac Microtechnology, adapts to the different pressure of each part of the body.
  2. It provides each area with adequate support. It also improves bed independence, so it absorbs movement well and is ideal for double beds.
  3. The layers of HR Densitech foam (30kg / m3) and Sofconfort memory foam insulate the springs and allow the mattress to adapt smoothly to the body, achieving an excellent enveloping effect.
  4. The exterior upholstery with Purotex fabric prevents the appearance of mites, minimizing the risk of allergy and asthma attacks in sensitive people.
  5. Thanks to its core of springs and the thermoregulate capacity of its foams, the mattress stands out for the freshness sensation it provides, by avoiding the accumulation of humidity.
  6. Therefore, we believe that it is ideal for people who tend to sweat during the night.

Also, its characteristics make it a good option for people of high weight (more than 100 kg or BMI greater than 30) and couples with large weight differences, since the independent pocket springs adapt very well to uneven pressures on the mattress.

And, thanks to the quality of its materials (especially the spring core, which is what we like the most) its useful life is also above average.

4. Dormio Esmeralda Reversible ViscoSoft Mattress - Best Low-Cost Memory Foam

Best Low-Cost Memory Foam
Dormio Esmeralda Reversible ViscoSoft Mattress
  • Reversible mattress with winter and summer face
  • Viscosoft layer on both sides of the mattress
  • Very tight price
  • Great adaptability
  • It takes between 24 and 48 hours to regain its shape and breathe
  • It can be a little soft for people of high weight (BMI over 30)
  • We have seen that it does not always present the thickness of 24 cm established by the manufacturer


  1. This mattress has a 3 cm layer of Viscosoft –a thermo-adaptable memory foam– on both sides, which makes it adjustable to different postures and body characteristics.
  2. Its ELIOCEL foam core gives it resistance and intermediate hardness.

  3. The combination of both materials results in a mattress that responds well in the areas of greatest pressure, giving good support without being excessively hard, which translates into a good feeling of comfort for side sleepers.

  4. Open-pore memory foam reduces heat build-up. Also, it has a warmer winter face and a summer face with breathable 3D fabric that provides freshness and greater air circulation, avoiding the accumulation of moisture and sweat during the warmer nights.

The perfect option if you have a tight budget and you are looking for a mattress with good adaptability or if you are sensitive to the temperature in bed.

The result is an economical mattress with good value for money, which adapts very well in almost all situations.

  2. Ideal for those looking for an excellent welcome feeling and for side sleepers who move around a lot during the night.

  3. This brand is committed to using memory foam with a density much higher (65kg / m3) than the market average, so it adapts even more to the body profile and generates an incredible feeling of welcome.
  4. It also quickly returns to its original position, making it a good option if you are one of those who move at night.
  5. Its medium firmness makes it a good option for people of high weight, and another highlight is its upper stretch fabric with natural cotton padding and antibacterial treatment.
  6. It has a total height of 24 cm once unpacked and left to recover for 24 hours.

The winter face, warmer but considerably less breathable, is the one with the high-density memory foam layer.

On the summer side (red), we find a layer of Viscosoft covered with Airfresh 3D fabric, which provides freshness. In the middle, we find the HR Byfoam foam layer that gives it its firmness.

What is the best type of mattress for sleeping on your side?

Our Best Mattresses team has analysed the points you should pay attention to when buying a mattress for side sleepers.

We recommend you pay attention to these points:

  • Good stability
  • High elasticity
  • Soft to medium firmness (4-6 out of 10 points on our scale)
  • Good pressure relief to prevent rotation of the pelvis
  • Good adaptability
  • Support areas (for example in the shoulder area)
  • Complement with a good pillow

The importance of stability and support

When buying a mattress, you should pay attention to the level of stability or support. Stability should not be confused with the degree of firmness; sometimes a soft mattress can be just as good or even more stable than a firm mattress.

The danger of choosing the wrong mattress when sleeping on your side is that your spine can become misaligned. You should avoid this if you don’t want to suffer from back and neck pain. The correct mattress should not be too hard or too soft; it is also important you take your body weight into account. If you sink too much into the mattress your spine could twist. A good mattress should support your body well in all positions so that your spine remains in a healthy orientation.

A mattress for sleeping on your side should have high elasticity and a good reduction in pressure points. Some mattresses are divided into ergonomic zones to give the correct support to each area of your body. These zones ensure that your head is supported better and that your shoulder and neck area sink a little deeper, leaving the spine in its natural shape.

What degree of firmness should you choose?

Finding the right degree of firmness for a mattress is often very difficult, especially since most new brands don’t reveal it. These brands claim to create mattresses for all types of people – the universal mattress.

For people who sleep on their side, we recommend a somewhat soft mattress, which has a rating of 4-6 points on the firmness scale, for heavier people we recommend choosing a slightly firmer model (6-8 points).

The mattress should have good support, as this helps to relieve pressure on the neck and back. It is important that the mattress adapts well to your body and that the pressure is distributed evenly or else you will sink into the mattress.

Foam mattresses high quality cover the above criteria, especially mattresses memory foam, latex foam or gel foam.

Pay attention to the rotation of your pelvis.

While sleeping on your side relieves lower back pain and is also good for reflux and sleep apnea, one of the problems with sleeping on your side is pelvic rotation. This happens when your upper body is turned in the opposite direction from the lower body, causing pain.

You can prevent this from happening by inserting a pillow between your legs when sleeping, as well as choosing the correct mattress. A good mattress provides adequate support and prevents pain.

Side sleepers should avoid mattresses that are too firm or too soft. Firmness should be medium or medium-high at most.

If you sleep on your side, you need a mattress that adapts perfectly to the contour of the body and provides relief from pressure points, especially hips and shoulders.

Here are some other factors to consider when finding the perfect mattress.


Most mattresses designed for side sleepers have some mixture of memory foam or latex.

Memory foam is known to be an excellent material for distributing weight and minimising pain at pressure points, such as the hips or shoulders while helping to maintain the natural position of the spine.

Latex or HR foams give the mattress more bounce and have a greater response to weight, that is, it quickly recovers its shape after you remove the pressure, such as when you move during the night.

In general, “conventional” box springs are not a favourite for side sleepers because they do not provide the same kind of adaptability to the body shape. However, there are mattresses with high-quality pocket springs that do provide that adaptability, and if you combine it with a topper, you will feel in the clouds.

Pressure relief properties

Side sleepers need to choose a mattress that “hugs” your body in just the right places, but does not make you sink into the bed. A mattress that “pushes” you up enough while lying down will give you just the right support your body needs to adjust to the natural curves of your body and keep your spine straight.

The right amount of firmness will also help distribute your body weight across the mattress, which means that your hips, legs, and shoulders won’t sag more than the rest of your body. This helps prevent aches and pains in those high-pressure areas.

Firmness level

Side sleepers tend to prefer mattresses with medium or medium-soft levels of firmness. If the mattress is too hard, it can cause discomfort in the joints.

On the other hand, if the mattress is too soft, it will not provide enough support. Find a mattress that is supportive but soft enough to minimise stress on the hips and shoulders.

Which types of mattresses are not suitable for side sleepers?

The classic spring mattresses are less suitable for people who lie on their side. Compared to latex mattresses, spring mattresses are not sufficiently point-elastic and do not allow side sleepers to sleep comfortably. If for some reason it has to be a spring mattress, you should at most buy a zoned pocket spring mattress.

Tips for sleeping on your side

If you sleep on your side, your neck must be at right angles to your shoulders. The implications of poor neck posture are a muscular issue. It can create pinches in the neck joints. These pinches can cause pain and numbness in the neck and under the arms.

Sleeping on your side, especially on your left side, is the recommended sleeping position for pregnant women. Do not forget to get a good pillow.


In terms of comfort and lying properties, this mattress is nevertheless clearly inferior to the models made of cold foam, Visco foam and natural latex. Normal latex mattresses made from artificial latex shouldn’t be the first choice for every side sleeper.
