How Firm Should a Queen Mattress Be for Back Pain?

Starting your day after waking up with pain in the back can be challenging. Millions of people in Australia suffer from chronic back pains which usually stem from an uncomfortable old mattress. Lack of proper support for the spine causes the muscles to be tight and joints to take additional strain, resulting in exhaustion and pain.

When buying a new queen mattress that is aimed at relieving back pains, you will have to make an important choice of what firmness is more suitable for you. Should you go for a luxurious and soft medium bed or maybe for a firm bed that will provide more support? In addition, you will need to compare various hybrid and foam beds like the Wowbeds Duo Mattress and Wowbeds Dreamer Mattress to see how different materials work with your body. 

At Wowbeds, we are dedicated to helping you in choosing the best balance of comfort and healing qualities. This guide will give you all the information you need on the matter of mattress firmness and spine health.

TL;DR: Summary

• Target the Right Firmness for Back Support: A medium-firm (7/10) mattress is widely recommended as the sweet spot for back pain because it balances deep pressure-point relief with robust structural support to keep your spine aligned.
• Match Firmness to Your Sleep Style:
1. Side Sleepers: Benefit from softer, medium cushioning (6 to 7/10) to relieve pressure on shoulders and hips.
2. Back & Stomach Sleepers: Require firmer, supportive surfaces (7 to 8/10) to prevent the midsection from sinking and causing unnatural spinal curves.
• Account for Body Weight: Lighter individuals (below 60 kg) need softer contouring to feel comfortable, while heavier individuals (above 100 kg) require firmer hybrid models to avoid bottoming out.
• Prioritise Advanced Hybrid Construction: Mattresses like the Wowbeds Duo (offering customisable firmness levels and 7-zone pocket springs) and the Wowbeds Dreamer combine targeted spinal alignment, motion isolation, and cooling tech to relieve back strain.
• Avoid Common Pitfalls: Don't buy purely based on showroom softness or keep a mattress past its 7- to 8-year lifespan, as sagging foam and weakened springs are primary culprits of chronic morning back pain.

Why Mattress Firmness Matters for Back Pain Relief 

The mattress serves as the basis of your spinal condition for about a third of your life span. The right position while lying would be one when the spine retains its natural neutral curve as it would in the case of standing in a healthy posture.

If the mattress is too soft, your heavier parts, abdomen and hips, will sink into the mattress, thus causing an unnatural curve of your spine in the form of the letter “U” and straining the muscles of your lower back as well as compressing lumbar discs. 

In case the mattress is too hard, the pressure will be applied directly on your shoulders and hips without any adaptation to the shape of your body; therefore, your spine will be out of its correct position. Best firmness guarantees even distribution of weight and full relaxation of your muscles during sleep. (More details on choosing the appropriate firmness can be found in our guide.)

Understanding the Firmness Scale (Medium vs. Medium-Firm vs. Firm) 

Firmness levels are generally calculated using a rating system that ranges from 1 to 10. Here '1' means 'ultra-plush cloud', while '10' is the term for the hardness of the board. In order to effectively deal with back pain problems, companies design specific comfort levels to meet specific ergonomic requirements:

Medium (6 out of 10)

A medium mattress guarantees you a deep-hugging experience along with supportive internal springs guaranteeing proper spine alignment. Dynamic multizoned springs provide support to different zones according to your body’s contours. The plush nature of the bed helps to relieve joint stress well. Hence, people with smaller body sizes also get required spine relief.

• Suitable For: People seeking a softer, cloud-like sleeping experience; side sleepers requiring plush padding in order to relieve shoulder and hip joints; and lighter people who find standard mattresses too rigid.

Medium Firm (7 out of 10)

The most sought-after option for Australian sleepers, it presents an ‘I got just what I need’ feel where the cushioning isn't too soft yet not hard. This middle ground of a rating strikes a balance between deep pressure point release and proper support for the lower back.

• Suitable for: All types of sleepers and couples with differing sleeping preference styles who find it difficult to choose between softness or firmness. (For an overview of top recommendations in the market, visit our review on the best queen mattress 2025.)

Firm (8 out of 10)

Created for sleepers that like to sleep on top of, instead of in, the bed; offers strong support, which you can immediately feel. The high density of the mattress helps avoid sagging in the middle area, verifying that your body is perfectly horizontal all through the night.

• Suitable For: Sleepers lying on their backs and/or stomachs, as well as side sleepers looking for strong structural support; heavy individuals needing max pushback; people recommended a firmer bed by a healthcare professional. This firmness guarantees that no bottoming out happens from the heavy weight of your body.

How Your Sleeping Position Dictates the Ideal Mattress Firmness 

The way you sleep is maybe the biggest determinant in terms of the amount of body support and push back that your spine needs to avoid discomfort.

Side Sleepers

Side sleeping exerts extreme pressure on the shoulder and hip joints. In case the mattress is hard, these joints are forced upwards, causing misalignment and lack of proper blood flow through the body. Side sleepers usually benefit greatly from a medium (6/10) mattress or even a medium-firm (7/10) mattress which provides ample cushioning without compromising support of the waistline. Lack of enough cushioning for these major joints may cause you to experience numbness in your arms and joint pain in the morning.

Back Sleepers

Back sleepers need a supportive sleeping surface to cradle their natural lumbar arch without causing the dense hips to sink. When you sink too deep into a soft mattress, your lower back arches into an unnatural shape, compressing the lumbar nerve roots. Medium Firm (7/10) and Firm (8/10) mattresses distribute weight evenly, keeping the spine neutral and well supported. 

By maintaining proper spinal alignment throughout the night, your core muscles are not required to do additional work while sleeping. The upper layer provides support between the spine and the mattress, preventing stiffness in the morning.

Stomach Sleepers

Stomach sleeping has long been associated with lower back pain since it causes you to sink your midsection into the mattress due to gravity's force, putting an extreme arch on your spine. Stomach sleepers need a supportive firm (8/10) mattress that raises the hips up to align with the head and shoulders. Your body's weight mostly sits in the hips, and without proper support, your hips act as a sinking anchor. Getting a higher-resistance mattress is the best solution to avoid the unnecessary spine overstretching caused by stomach sleeping.

Body Weight and Spinal Alignment: Finding Your Match 

Body weight has a great effect on how a mattress works with your pressure points. A mattress that is medium-firm for average body weight may turn completely different for people on both extremes of body weight:

• People with Light Body Weight (below 60 kg): They don’t press with sufficient force to compress firm foam layers and, hence, need medium (6/10) mattresses to enjoy proper body support and pressure relief.
• People with Average Body Weight (60 kg to 100 kg): People of this weight usually have the best spinal alignment and lumbar support in medium-firm (7/10) mattresses, which offer a combination of body support and pushback.
• People with Heavy Body Weight (above 100 kg): They usually sink deeply into soft comfort layers of the mattress, which might affect the spinal alignment, and hence need firm (8/10) mattresses or thick hybrid mattresses with sturdy pocket springs.

Common Mattress Mistakes That Worsen Back Pain 

Avoid making the following mistakes to make sure that your money spent on a queen mattress works as a solution for you:

• Keeping a Mattress Past Its Prime: Usually, most common mattresses wear out after 7 to 8 years because all of the inner support starts wearing out and makes a bed less firm, which is why there is lower back sagging. The compression of inner foams and lack of tension in spring systems make a bed unable to give you the proper ergonomic support for your spine. Knowing these signs helps you not to go through weeks of growing back pains each morning.
• Buying Based on Softness Only: Choosing too-soft mattresses in the store, thinking that they are very comfortable. In reality, it may turn out to be very harmful to your spine. If you try a mattress only for five minutes in a showroom, it does not mean that your bed will stay that soft for a whole night of sleeping.
• Disregarding the Sleep Needs of the Partner: When compromising on a firmness rating that offers balance (such as medium firm, 7/10) when sleeping in the same bed with your partner whose sleeping needs differ from yours. (For detailed guidance, read our article on how to select the right mattress firmness for back pain relief.) Having either of the partners sleep on a mattress that is too soft or too hard will result in misalignment problems and restless sleep. Choosing the universal medium-firm firmness is beneficial for both individuals.

Frequently Asked Questions (FAQs)

What mattress firmness do spine specialists recommend for back pain?
Most spine specialists and physical therapists recommend a medium-firm (7/10) mattress. It provides the right balance of comfort and support by cushioning pressure points while helping keep your spine properly aligned. 

Is a firm mattress always better for back pain?
No. Although a very firm mattress may suit stomach sleepers and heavier individuals, it can put extra pressure on the shoulders and hips. This may cause poor spinal alignment and increase back pain, especially for side sleepers. 

How do I know if my mattress is causing my back pain?
If you wake up with stiffness or body aches that improve as the day goes on, or if your mattress has visible sagging, it may be causing your back pain. 

Are hybrid mattresses good for back pain?
Yes. Hybrid mattresses, such as the WowBeds Duo, combine the comfort of memory foam with the support of pocket springs. This helps relieve pressure while keeping your spine properly supported, making them a great choice for back pain. 

How long does it take to adjust to a new mattress firmness?
It usually takes 2 to 4 weeks for your body to adjust to a new mattress. During this time, your body adapts to the improved support, and the mattress begins to fit your sleeping position.
