The right firmness level depends on your body weight, your sleeping position and your personal sleeping comfort. As a rule of thumb, lighter people tend to prefer softer mattresses, heavier people medium-firm to firm mattresses. The decisive factor is that the spine lies straight and the shoulders and pelvis can sink in comfortably. Find out more about firmness here.

Why is the right mattress important?
The right mattress is extremely important because it directly affects how well you sleep. Restful sleep is crucial for your health and well-being. If the mattress is too hard or too soft, it can lead to back pain or muscle tension. In addition, the right mattress ensures that your spine remains in a natural position, which helps prevent back problems in the long run. And let’s be honest, who wants to wake up with back pain? A good mattress can also help reduce allergic reactions if it’s made from hypoallergenic materials. It helps you sweat less or feel less cold by regulating your body temperature. So invest a little time and effort into finding the right mattress—your body will thank you for it.
What types of mattresses are there?
There are various types of mattresses, each with different characteristics. Here are the most common ones: Innerspring mattresses offer good support and are ideal if you tend to sweat a lot at night, since they’re well-ventilated. Memory foam mattresses conform to your body and are great for people with allergies. Latex mattresses are elastic and particularly durable—perfect if you’re looking for an option that promotes sustainability.
Cold foam mattress
A cold foam mattress is made of elastic foam that adapts flexibly to the contours of the body. It is quiet, light and retains heat. Ideal for a quiet and comfortable sleeping experience.
Advantages: high point elasticity, very good lying comfort, easy to care for and allergy-friendly.
Disadvantages: The quality of cold foam mattresses can vary greatly. Cheap mattresses are often less durable and less breathable. However, high-quality mattresses with special cold foam and ventilation channels are extremely breathable and also durable. Träumeland, for example, offers high-quality, ventilated cold foam mattresses that score highly in terms of air circulation.
Perfect for anyone who appreciates comfort, rest and ergonomic support, ideal for side and back sleepers who are looking for restful sleep at a high level.
Latex mattress
Latex mattresses are made of natural or synthetic latex and offer even, firm support thanks to their high elasticity. The material is breathable, hygienic and particularly durable.
advantages: excellent body adaptation, antibacterial, quiet and flexible for adjustable slatted frames.
disadvantages: higher weight and price. Latex mattresses also change with the seasons. Latex mattresses react strongly to temperature differences. They can become firmer in winter and softer in summer. They also store heat when it should be cooling and feel cool when you actually need warmth.
Perfect for allergy sufferers and anyone who values natural materials, hygiene and firm lying comfort.
Spring mattress
Spring mattresses have a core of steel springs surrounded by layers of foam or fleece padding. Pocket springs react precisely to pressure and offer particularly good support, while Bonell springs yield over a larger area. The hollow spaces inside make this type of mattress breathable and ensure a pleasantly cool sleeping environment.
advantages: stable support and adequate ventilation.
disadvantages: slightly more flexible, so you feel your partner's movements more easily. Metal springs can absorb and transmit electromagnetic influences, an aspect that some sleepers find disturbing.
Perfect for anyone who sweats easily while sleeping and prefers a firm, ventilated mattress.
Find the best mattress for you
The perfect mattress is as individual as your sleep. Whether you prefer to sleep on your side, back or stomach. What matters is that your mattress provides optimum support for your body and feels comfortable.
If you are unsure which mattress is right for you, our mattress finder will help you:
Simply answer a few short questions about your sleeping habits and you will receive a personal recommendation that is perfectly suited to you.
Which mattress is best for my sleeping position?
The best mattress depends heavily on your sleeping position. Side sleepers often need a softer mattress to relieve pressure on the shoulders and hips. Back sleepers usually benefit from a medium-firm mattress, while stomach sleepers often prefer a firmer version to support the back. Also think about the material: cold foam mattresses offer good point elasticity. And don't forget to turn the mattress regularly to prolong its life.
Which mattress suits me as a side sleeper?
As a side sleeper, you need a mattress that keeps your spine straight and prevents pressure points on your shoulders and hips. A soft to medium-firm mattress with good point elasticity is ideal, as it gives way in the right places. Materials such as cold foam or latex are often a good choice. As a side sleeper, you should also make sure that your neck is adequately supported. Special pillows for side sleepers are suitable for this.
To mattresses for side sleepers
Which mattress suits me as a stomach sleeper?
For stomach sleepers, it is important to choose a mattress that is not too soft to prevent the spine from sagging. If you sink too far into the mattress, this can result in back pain. A medium-firm to firm mattress offers the right support. Make sure that the mattress distributes the pressure evenly so that you lie comfortably. Spring mattresses or hard cold foam mattresses are the ideal choice here. The pillow does not have to be special, but it is important that it is not too high. Otherwise your neck will be overstretched and you will suffer from neck pain.

Which mattress suits me as a back sleeper?
As a back sleeper, it is important to choose a mattress that offers sufficient support for your spine. A medium-firm to firm mattress is often ideal as it helps to maintain the natural curvature of the spine. All in all, however, it's up to you if you prefer to lie on a softer mattress - this is not harmful either. However, the mattress should be point-elastic to support you exactly where you need it. Make sure that the mattress is not too soft to avoid sagging.

How do I find the right firmness level?
To find the right firmness level, you should pay attention to your body weight and sleeping position. As a rule of thumb: lighter people should prefer softer mattresses, if you weigh more, your mattress should be correspondingly firmer. However, it is up to you which firmness level you choose. Try out different firmness levels and pay attention to how your body feels after a night on it. If you share your bed with your partner, we recommend choosing 2 narrow mattresses with different firmness levels.
Soft to medium-firm mattresses
Soft to medium-firm mattresses are great if you're looking for a good balance between comfort and support. They are ideal for back sleepers and many side sleepers because they provide enough pressure relief without being too soft. Make sure that the mattress adapts well to your body and keeps your spine in a natural position.
Soft to medium-firm mattresses are best suited for:
- Side sleepers
- Back sleepers
- Sleepers who like to change position
- People weighing less than 90 kg
Discover medium-firm mattresses
Firm mattress
Firm mattresses are ideal if you like to sleep on a stable surface or are a stomach sleeper. They offer good support, especially for heavier people. Make sure the mattress is not too hard to avoid pressure points.
Firm mattresses are best suited for:
- Stomach sleepers
- Back sleepers
- Sleepers who like to change position
- People weighing over 90 kg
Which size is the best choice for your bed
The right mattress size depends on your bed frame and your personal preferences. For singles or as a youth bed, a width of 90 or 100 cm x 200 cm is often sufficient, while couples usually opt for 160 x 200 cm or 180 x 200 cm. Make sure that the length is slightly longer than your height so that you can lie comfortably. However, it is also advisable to choose two narrow mattresses, even in a double bed. The reason for this is that the firmness levels can be individually adapted to the person. Not everyone has the same needs as their partner. It is therefore advisable to choose two 90 x 200 cm mattresses.
Care tips for your mattress
To keep your mattress in good condition, turn and rotate it regularly. It's best to turn it every few months. This will help you avoid bedsores and prolong its life. It is also important to ventilate it well to avoid moisture and unpleasant odors.
When is it time for a new mattress?
It may be time for a new mattress if you wake up in the morning with back pain or if you notice that your mattress is sagging. Even if you often sleep restlessly or your sleep is not restful, this could be due to an old mattress. Another sign is if your mattress is more than seven to ten years old. Also look out for visible signs of wear and tear such as dents or cracks. Listen to your gut feeling: if you no longer feel comfortable, it may be time to invest in a new mattress. A good mattress can significantly improve your sleeping comfort and is an important investment in your health.
What else should you look out for when choosing a mattress?
Pay attention to your allergies and special needs when choosing a mattress. Hypoallergenic models or mattresses with removable, washable covers are great for allergy sufferers. And don't forget that the mattress must also suit your personal comfort level.

To look after your mattress properly, you should turn and rotate it regularly, ideally every three months. This helps to distribute wear and tear evenly. Use a mattress protector or topper to protect it from dirt and stains. Air your mattress regularly by steaming it out for a few hours without bedding. Vacuuming helps to remove dust and mites. If stains occur, act quickly and treat them with a mild detergent and a damp cloth. Make sure that the mattress is completely dry before you cover it again. You can find out more about mattress care in our article: Proper mattress care
You should flip your mattress about 2 to 4 times a year. This helps distribute wear caused by body weight and stains from sweat evenly. It’s best to flip the mattress when the seasons change. At first, you can also flip the mattress every 2 weeks to help it conform evenly.
However, how often you should flip your mattress also depends on the type of mattress:
- Foam or latex mattresses: These should be flipped every 2 months. Switch the top and bottom sides (head and foot ends).
- Innerspring mattresses: It’s recommended to flip them 2 to 4 times a year.
- Zone mattresses or models with varying firmness levels: These mattresses have different support zones. They should not be flipped completely to the other side. Doing so usually changes the firmness level and thus the feel of the mattress—these should only be rotated 180°C.
The gap between two single mattresses can be easily closed. The most common solutions are:
- A mattress topper, which is between 4 and 9 cm thick and lies on top of both MATTRESSES. This closes the gap and can enhance or optimize the comfort of the MATTRESSES.
- A “love bridge,” which is a T-shaped foam wedge placed in the gap between the MATTRESSES.
- A fitted-sheet that is placed over both MATTRESSES and pulls them together.
- A single, continuous MATTRESS is the best solution. However, these are often very heavy and do not allow for individual adjustment of the hardness level.
Which mattress is right for me? With our mattress finder, you can find out which model is right for you in just 2 minutes. Answer a few quick questions about your weight, height, sleeping position, and any physical issues. Our online mattress advisor will provide you with recommendations for the best mattress.
Purchasing the wrong mattress often leads to poor posture or pressure points. To avoid this, be sure to use the mattress finder first.
Whether you choose cold foam or innerspring depends on your needs. If you have back pain or other issues such as pressure points or discomfort, a cold foam mattress is generally the better choice. Its key advantage is its high point elasticity. In other words, it gives way only where the body needs it to (at the shoulders or hips) and provides support exactly where it’s needed (at the waist). This allows the body to adjust ergonomically. It relieves pressure on the spine and helps prevent pain and pressure points.
Cold foam mattresses are ideal for people with back pain or muscle tension.
- They are highly adaptable—they conform precisely to the body’s contours and help prevent poor spinal alignment.
- They are highly breathable and ensure optimal temperature regulation. No excessive sweating. Optimal moisture wicking.
- Important: Always pay attention to the quality of the mattress. Inexpensive cold foam mattresses are often less durable and less resistant to deformation.
Innerspring mattresses or pocket-spring mattresses are ideal for you if you’re looking for a firm mattress or if you’re heavier.
- They offer exceptionally high support and often provide less give than conventional foam mattresses.
- They are particularly well-suited for people with a higher body weight.
