What's a good mattress? There are a lot of mattresses on the market, and for many people it all stays a bit abstract sometimes. Not only are there many types or types of mattresses, but within one type you usually also have a large variation in quality. In addition, a good mattress for one person can feel less good for another. In our mattress guide we try to give structure to the types of mattresses, and their pros and cons, so that you can make the right choice.
The different types of mattresses
Pocket spring mattresses
Pocket spring mattresses contain springs, which are all individually packaged in so-called pockets. Because the feathers are all packaged separately, they can also move independently of each other to give support to the body where it needs to be. Most pocket spring mattresses are divided into zones. The most common number of zones are 5 and 7, but a mattress can contain up to 9 zones.
What is the use of these zones? Each zone has a certain hardness, specific to a certain part of the body. The hip zone, for example, will contain springs that provide less back pressure, so that the pelvis can relax. The more zones in the mattress, the more the mattress adapts to the specific part of the body that lies on it. Pocket spring mattresses are also finished with a covering layer, usually of cold foam, memory foam or latex. This layer provides extra lying comfort.
Cold foam mattresses
Cold foam mattresses are made entirely of resilient foam. Thanks to its resilience, the foam provides counter pressure when pressed harder. So it gives extra support in the places where it is most needed. The foam is usually assigned an HR (High Resilience) value. The higher this value, the more foam is incorporated in the mattress. This also results in a higher resilience, and therefore a longer lifespan.
Another major advantage of cold foam mattresses is good ventilation. Due to the open cell structure of the cold foam, the mattress is well ventilated and has excellent moisture regulation. People who sweat easily at night will certainly benefit from a cold foam mattress.
Memory foam mattresses
Memory foam mattresses owe their name to one of the most important properties of the foam: when you press the mattress down, it slowly rises again. This makes the mattress pressure-reducing, because the body weight is distributed over a larger surface area. Another name often used for memory foam is visco or NASA.
Memory foam lies somewhat softer, and can also feel warm because it reacts to body temperature. The mattress moves towards the body through that combination of body temperature and body weight. This makes memory foam suitable for people with physical complaints, or people who want to lie somewhat softer. It is often not recommended for heavier people.
Latex mattresses are very supple and stretchy. Latex is a natural product, and is characterized by a high elasticity, which also allows it to form perfectly towards the body. Latex still has a few handy properties: it is naturally antibacterial, and repels mould and house dust mite. A value is usually associated with latex, namely specific gravity (SG). The higher this value, the more latex is incorporated in the mattress. This ensures greater resilience and durability.
Latex mattresses retain heat longer. They do not have a good open cell structure, as is the case with cold foam mattresses. As a result, this mattress ventilates slightly less well. Latex mattresses are also often slightly more expensive to purchase.
Polyether mattresses consist of polyether foam, which is often cheaper to buy. Polyether foam has less resilience and a closed cell structure, making it less ventilated. The lifespan of these mattresses is therefore also somewhat less. Polyether mattresses are, partly due to the price, more often purchased for places where there is less sleep, such as a guest bed.
Inner spring mattresses
Inner spring mattresses consist of springs that are connected by a single spiral thread. On top of this, these mattresses also have a covering layer, for example in cold foam, memory foam or latex. Inner springs are often a bit cheaper, but the support is therefore less effective than with other mattresses. Depending on the type of covering layer, ventilation is often very good.
