In addition to a bed, a good and restful night's sleep requires the right mattress. So far, so good. But if you want maximum sleeping comfort or find your existing mattress too hard, too soft or uncomfortable, you can upgrade the comfort of your bed system comparatively easily with a 9 cm thick mattress topper.

A topper does not cost a lot of money and is usually much cheaper than a new mattress. However, its effects on the sleeping environment are immense, so a mattress topper is now a popular comfort upgrade to improve the feeling of lying in bed and sleep overall.

What is a 9 cm thick mattress topper?

A mattress topper with a height of 9 cm is a mattress topper made of foam that is similar in core and structure to a mattress. This is why a topper is often referred to as a mattress topper or a mattress on top of a mattress. With its 9 cm thick foam layer, the topper complements the comfort properties of the mattress underneath. If a mattress is perceived as too soft or too firm, a mattress topper can correct this unpleasant lying sensation with its additional foam layer. A topper can also make a bed system noticeably more comfortable, for example by improving heat regulation to prevent night sweats or freezing.

To ensure that the 9 cm thick mattress topper with foam core fits the bed system perfectly and that the edges of the mattress and topper fit together perfectly, the size of the topper must be selected to match the size of the mattress.

Double beds with separate mattresses are an exception. In this case, a large mattress topper in the same size as the bed system can be used to influence the sleeping comfort of the entire bed. Or two toppers in half the size of the bed to influence both sides of the bed differently. This makes sense for couples who prefer different firmness levels, for example.

A mattress topper can be used on any bed system to improve lying and sleeping comfort. A topper is part of the basic equipment for box spring beds. A mattress topper improves the feeling of lying in the:

• Single bed
• double bed
• Box spring bed
• Children's bed and youth bed

For which bed sizes are mattress toppers with a height of 9 cm available?

Mattress topper with 6 cm height for all standard bed sizes

Mattress topper with a height of 7 cm for all standard bed sizes

The thicker the mattress topper, the greater the effect on the lying sensation. However, there is a minimum and maximum height for toppers. The mattress topper should have a core height of at least 6 cm so that the additional padding can bring about a noticeable change in the lying sensation. Thinner toppers do not achieve any noticeable change and are usually only used as mattress protectors to protect the mattress from premature wear or soiling. Conversely, a mattress topper should not be higher than around 12 cm so that the supportive properties of the mattress underneath are maintained. a topper should improve and support the mattress with additional comfort properties, but should never replace it.

Can a 9 cm thick mattress topper make a mattress softer?

Absolutely! The 9 cm thick foam layer of the mattress topper changes the feeling of lying on mattresses that are too hard. The additional padding makes the mattress feel noticeably softer. The pleasantly soft layer acts as additional cushioning between the body and the mattress without overriding the important support properties of the mattress. Due to its special physical properties, the 9 cm thick foam core of the topper offers a good compromise between additional softness and support, which is why the mattress topper with a height of 9 cm is one of the most popular topper heights for making hard mattresses softer.

And vice versa? Can a 9 cm topper make a soft mattress harder?

Yes and no! As conventional mattresses are usually significantly higher than the 9 cm thick mattress topper, the basic character of the mattress is retained when the topper is used. This means that parts of the musculoskeletal system, such as the shoulders or pelvis, may sink too deeply into the mattress underneath, even with a topper, leading to an uncomfortable misalignment of the body. However, a mattress topper with an appropriate firmness level can help to provide a firmer support surface, which is often sufficient if the mattress is perceived as too soft - but the support properties of the mattress actually suit the body. When choosing a topper, you should make sure that it has a higher firmness level than the mattress.

Can a 9 cm thick cold foam topper make a mattress more comfortable?

A resounding yes! Even if you already have a good mattress, you can get more comfort out of your mattress with the mattress topper. The feel of a mattress is primarily determined by the support surface. If it is pleasantly soft, as with the 9 cm thick mattress topper, the body relaxes more quickly. Even if back or joint pain or pain in pressure-sensitive areas, such as the shoulder or pelvic area, occurs with increasing age, the 9 cm thick topper core made of point-elastic cold foam can have a pain-relieving effect and help you sleep pain-free thanks to improved pressure relief and support.

There are many good reasons to use a mattress topper with a 9 cm thick foam core to improve lying comfort. Not doing so would be a waste! The mattress topper helps you sleep noticeably better night after night for comparatively little money. It is not uncommon for a supposedly bad mattress purchase to turn out to be a stroke of luck with a mattress topper. This is the case when the mattress is optimally tailored to the body weight and individual needs, but for various reasons the lying sensation is still perceived as uncomfortable.

As a rule, you can even save money with a mattress topper, as it is a practical mattress protector that ensures that a mattress wears out less, significantly extending its lifespan.
