Everything You Need to Know About Mattress Firmness

In the quest to find the perfect mattress, there are many things to consider – support, size, comfort and more! Though the key to long-lasting, healthy sleep is mattress firmness. Whether you love to sink into a softie or need a firm mattress to sleep like a baby, this guide tells you all you need to know about mattress firmness so you can find your dream match.

What is Mattress Firmness?

When you start browsing online, you will soon become familiar with the phrase ‘mattress firmness rating’. This is how brands indicate how soft or firm a mattress feels. There is currently no industry standard in terms of mattress firmness rating. It is much determined by the materials used and their various densities.

Your sleeping position and weight can both affect your ideal mattress firmness, which we will get to shortly.

First, let’s break down a typical mattress firmness rating scale and which materials can make it feel ‘soft’ or ‘firm’.

The Firmness Scale

Have a look at the mattress firmness scale, starting with one being ‘supremely soft’ and ten being ‘incredibly firm’.

Extra Soft 1-2	If a cloud were a mattress, this would be it. Think softer-than-a-marshmallow soft!
Soft 3-4	This rating indicates you are still getting a soft, sinking feeling with a slight firmness.
Soft- Medium 5-6	Now you are moving more towards a firmer feel, cushioned with a slight, sinking softness.
Medium Firm 7-8	Firm, though not too firm. This ‘just right’ rating balances firm support with cushiony comfort.
Extra Firm 9-10	The firmest of them all, this sleep surface is ideal for heavier sleepers and those who crave a firmer feel.

What Materials Make a Mattress Soft or Firm?

Another indicator of mattress firmness is the materials used. If you are looking for lots of support, choose orthopaedic grade memory foam – this will naturally contour to your sleeping position and help you feel cradled.

Pocket springs can give a slightly softer, more bouncy feel. If you are after the best of both, try a hybrid like our Bamboo Hybrid Mattress Pro, which combines advanced support with pocket spring technology, providing the ideal balance. Our carefully engineered BioCell Foam™, OrthoAlign Foam™ and seven zones of premium pocket springs hold you in cushiony comfort without compromising pressure point perfect support.

Alternatively, our Hybrid Bamboo Mattress features DualFlex Foam™, a deluxe dual layer of highly resilient, orthopaedic grade memory foam which works in perfect harmony with up to 800 individually encased pocket springs. This results in a medium-firm mattress that is both comfortable and supportive.

What Mattress Firmness is Right for You?

While sometimes it’s good to take a chance, bedtime is something you want to get ‘just right’.

Before you decide, understanding the mattress firmness level that best suits your sleeping position is critical. Here are some things for each type of sleeper to consider:

Side sleepers – Healthy spinal alignment is key for side sleepers while ensuring your pressure points are supported and comfortable. Naturally, contouring memory foam with soft cushioning will keep your hips and spine happy.

Front sleepers – Front sleepers can benefit from a firmer feel that provides healthy hip and spine alignment and extra support.

Back sleepers – Ensuring your hips are lifted is essential for back sleepers, so a slightly firmer surface can suit you.

Does Weight Affect What Mattress is Best for You?

Your weight can help indicate what mattress firmness will better suit your needs. For lighter sleepers, adequate cushioning and slightly softer surfaces can keep you sleeping comfortably. A somewhat firmer surface with adequate support for heavier sleepers can prevent over-sinking.

Firmness and Support - Are They the Same Thing?

It’s easy to confuse mattress firmness with mattress support, though are they the same thing? Not exactly. Mattress firmness is what you experience when you take that first relaxing lie-down onto your bed.

Mattress support is measured by the quality and type of memory foam that it is made with. Quite often mattresses that offer more support tend to have a firmer feel. Those that combine memory foam with cushioning pocket springs can offer more of a balance between comfort and support. Our Hybrid Bamboo Mattress range does just that, allowing our mattresses to provide a wider range of sleepers the perfect night’s sleep.

Is There a Firmness Difference Between our Hybrid Bamboo Mattress and our Hybrid Bamboo Mattress Pro?

There is a slight difference in where our two premium mattresses fall on the firmness scale – our Hybrid Bamboo Mattress comes in at a 6.5 while our Pro version is a 7. There’s not too much in it, but if you do prefer a slightly firmer mattress then our Hybrid Bamboo Mattress Pro will tick every box for you.
