The Simba is one of our favourite hybrid mattresses.

The Simba mattress is supportive enough to prevent a build-up of tension, but also soft enough to allow your body to sink in where necessary.

This allows for optimal spinal alignment. 🦴

Unfortunately, the cover is not machine-washable - we'd recommend making use of a mattress protector to safeguard your mattress. 🧼

What is a medium-firm mattress?

A medium-firm mattress is suitable for people of a small or medium build, who do not like firm mattresses, and who do not suffer from any back problems. They are also suitable for heavier-weight people who like a soft mattress but still desire the quality and support necessary for their health.

Stability is essential in a mattress. This is determined by the composition of the mattress and refers to how much support the mattress gives you. Good support takes into account the optimal alignment of the spine. It is important not to confuse stability and firmness. A soft mattress can offer as much support as a firm mattress.

A medium-firm mattress offers a balanced approach. It is not too soft and not too firm but still offers the required stability to optimally support your body and keep your spine in a healthy alignment. This ensures that your body remains in a great position, allowing you to get a good night's rest.

Sleep Hero firmness scale

In order to better explain the degrees of firmness of different mattresses, we’ve come up with the Sleep Hero firmness scale. Our firmness scale is based on scores awarded by our independent reviewers. It is used extensively on the Sleep Hero website and we've used it to rate each mattress in our mattress reviews.

If you’re looking for a medium-firm mattress, then we’d advise you to look at mattresses with a rating between 5 and 6.5 out of 10 on the Sleep Hero firmness scale.

What type of sleeper is a medium-firm mattress suitable for?

A medium-firm mattress is suitable for a wide variety of people and body types. It can support you well, regardless of whether you’re short, tall, skinny, or heavier. It can also support you well if you sleep on your side, your back, or your stomach. Ultimately, a medium-firm mattress is a mattress for all.

However, the exact feeling of lying down on a mattress will depend on your preferences and your body size. If, for example, you’re a short and skinny person, then a medium-firm mattress may seem firmer to you than it would for someone who is taller or of a larger build, and vice versa.

Generally, we would recommend a medium-firm mattress for people weighing between 50 kg and 100 kg.

Why choose a medium-firm mattress?

Most people think that a firm mattress is better than a soft mattress. This isn’t necessarily true. A poor quality firm mattress can cause as much damage as a poor quality soft mattress. Ultimately, what’s important is the support a mattress gives.

You need to find a mattress that supports your body and ensures that your spine remains in its optimal alignment, without creating unnecessary pressure points in your shoulder and hip areas. This will allow your body to relax sufficiently and doesn't cause back or neck pains.

Body alignment

A good medium-firm mattress will function as an orthopaedic mattress and keep your body in its optimal alignment while you sleep. This allows you to get a good night’s rest and keep your body well-supported and healthy.

Conclusion

By choosing a medium-firm mattress, you will get the perfect mattress that’s neither too soft, nor too firm. It’s also a great compromise for couples who cannot agree on the desired firmness of their mattress.

There are many high-quality medium-firm mattresses available. One of our favourites, though, is the Simba Hybrid.

My mum calls me "bear" because I like to sleep so much. I never knew that, one day, that would be a very useful skill. Can you tell that I've found my calling?
