Your weight has a lot of influence on the firmness of your mattress. The heavier you are, the firmer the mattress support should actually be. If you are a lightweight, it is better to choose a soft mattress.

How is the firmness of mattresses measured?

By lying down on a mattress, you immediately experience for yourself how hard it feels. In addition, you can also look for a combination of a letter with a number. In fact, mattress firmness is usually shown in H1, H2, H3 or H4, which you can read more about below. Although you also often hear soft, medium and firm or soft, firm and extra firm.

  • H1: H1 is the softest mattress. This is especially suitable for the lightweights among us.
  • H2: H2 is a soft/medium mattress and is suitable for back and side sleepers.
  • H3: H3 stands for medium/firm. This type is suitable for back and side sleepers and notorious stomach sleepers.
  • H4: H4 is thus the firmest mattress and is especially suitable for persons heavily built.

What other factors affect the firmness of a mattress?

So your weight has a lot of influence on the firmness of a mattress, but there are basically a lot of other factors to consider in this area. For example, your height also plays a role on hardness. The taller you are, the more stretched your back often is, and thus the firmer the mattress should actually be. Consequently, this means that the Dutch for example, generally choose mainly firmer mattresses.

In addition, it is also important to pay attention to your sleeping position before buying a mattress. A little disclaimer, because a mattress is supposed to be suitable for all sleeping positions. However, often you have a preferred position for falling asleep. This is especially true if you are a stomach sleeper. Firm mattresses are then more suitable, depending on the volume of your belly, of course. Sleeping on your stomach requires a little more effort from your body. Your lower back gets stretched more and your neck starts to get a little more torsion. So pay attention to the pillow as well. It is best to use no pillow or a very low pillow to keep torsion as low as possible. Basically, all mattresses are reasonably suitable for back and side sleepers.

Of course, you must also consider your own preferences. It could be that by all guidelines, hard mattresses are better, but you still find this terrible. If this is the case, it’s really better to choose a soft one anyway. After all, your sleep comfort is important, so your preference affects this.

Can a mattress be too hard?

Yes, a mattress can definitely be too hard. So that’s why it’s so important to choose the right firmness when buying a mattress. If your mattress is too hard, it can cause several problems. There is more pressure on your joints and bones. That can create sores. You will also turn and turn more often if you sleep too hard. And that disrupts your deep sleep.

A mattress that is too hard can also restrict your blood circulation. This is because the pressure points in your pelvis and shoulders are overloaded. This is especially true if you turn while sleeping. As a result, you may experience pain in your back when you wake up.

Can a mattress be too soft?

So a mattress can be too hard, but unfortunately it is also possible that you are lying on a bed that is actually too soft. Again, this has a few drawbacks, but the biggest downside of a mattress that is too soft is the hammock effect. This makes it feel a bit like your mattress is sagging all the way through, making it feel like you’re lying in a hammock.

The hammock effect prevents the spine from receiving optimal support, making your back look like a banana when lying on your side. Which can cause back and shoulder pain. In addition, you can sink too deeply into a mattress that is too soft, making it feel like your body is completely enclosed. As a result, moisture removal and heat regulation will be a little more difficult and you will sweat. And if you sink deep, your range of motion will be limited, so it takes more energy to change sleeping positions.
