Choosing a mattress isn’t as simple as picking the softest or firmest option on the market—it’s about finding the right feel for you.
With options ranging from soft medium or firm mattresses, the entire mattress world can seem a bit confusing, especially when everyone’s idea of comfort is different.
Should you go with a plush, cloud-like soft mattress, a balanced medium feel, or a firm mattress for extra support? The truth is that your ideal mattress depends on factors like your sleep position, body type, and personal comfort preferences.
Seems confusing? Let’s break down what you need to know to find your perfect comfort level and sleep soundly every night!
Why Mattress Firmness Matters?
A mattress isn’t just a place to lay your head—it’s a key player in the quality of your sleep, your spinal alignment, and even your overall health. Besides, choosing the right firmness is essential for a few reasons:
- Support and Comfort: A mattress that’s too soft or too firm can cause discomfort and may not provide the support your body needs.
- Spinal Alignment: The right mattress keeps your spine in a neutral position, helping to prevent back pain and promote good posture.
- Longevity and Quality: A mattress that’s well-suited to your body type and sleep style will last longer, maintaining comfort and support over time.
Understanding Mattress Firmness Levels
Firmness refers to how soft or hard a mattress feels, and it’s usually rated on a scale from 1 to 10. While every brand might have slight variations, the general scale goes something like this:
- Soft (1-3): Ultra-plush with a deep “sink-in” feel.
- Medium (4-6): A balance of softness and support.
- Firm (7-9): Very supportive, with minimal give.
- Extra Firm (10): Extremely firm and unyielding, providing the most support.
Soft Mattresses – Who Are They For?
Soft mattresses (typically a 1 to 3 on the firmness scale) are designed for those who love a cloud-like sleep experience.
Best For
- Side Sleepers: Soft mattresses cushion pressure points like the shoulders and hips, making them ideal for side sleepers.
- Lightweight Sleepers: Lighter individuals may find softer mattresses more comfortable since they won’t sink as deeply.
- Those Seeking a Hugging Feel: Soft mattresses are perfect if you love the sensation of being cradled or “hugged” by your bed.
Potential Drawbacks
- May Lack Support for Back and Stomach Sleepers: Without enough support, these mattresses might lead to spinal misalignment for certain sleeping positions.
- Can Wear Out Faster: Softer mattresses may not be as durable, especially if the materials aren’t high quality or if used by heavier individuals.
If you love a cozy, enveloping feel, a soft mattress might be calling your name, especially if you’re a side sleeper who prioritizes comfort around pressure points.
Medium Mattresses – The Versatile Choice
When in doubt, a medium mattress (generally a 4 to 6 on the firmness scale) is often the safest option. Medium mattresses offer a balanced feel that combines enough plushness for comfort with enough firmness for support.

Best For
- Combination Sleepers: If you shift positions throughout the night, a medium mattress provides comfort for multiple sleep styles.
- Back Sleepers: Medium firmness supports the natural curve of the spine for back sleepers, promoting proper alignment.
- Couples with Different Firmness Preferences: Medium mattresses are a happy middle ground for partners with varying preferences.
Potential Drawbacks
- Might Feel Too Firm for Dedicated Side Sleepers: Side sleepers who prefer a very soft surface might find medium mattresses slightly too firm.
- May Be Too Soft for Heavier Individuals: Heavier individuals may find medium mattresses lack the support they need, especially if they sleep on their stomachs.
Overall, medium mattresses work well for a wide range of sleepers. So, if you’re sharing the bed or switching between different sleeping positions, medium firmness could be the perfect fit.
Firm Mattresses – The Supportive Option
Firm mattresses, often rated between 7 and 9, offer sturdy support and a surface that minimizes sinking. These are ideal for people who need solid support without the plushness.
Best For
- Stomach Sleepers: Firm mattresses help keep the spine aligned for stomach sleepers by preventing hips from sinking in.
- Heavier Individuals: People with larger body types benefit from the extra support, which helps distribute weight evenly.
- Back Pain Relief: Firm mattresses can provide the right amount of support for those with back pain, promoting better alignment.
Potential Drawbacks
- Too Firm for Side Sleepers: Firm mattresses can create pressure points for side sleepers, especially around the shoulders and hips.
- Can Feel Uncomfortable to Some: If you prefer a soft or plush bed, firm mattresses can feel too hard and uncomfortable.
If you need support above all else and want to avoid that “sink-in” sensation, a firm mattress could be your ideal choice.
Factors to Consider When Choosing Firmness
When deciding on mattress firmness, make sure to think about these personal factors:
Sleep Position
- Side Sleepers: Generally prefer softer mattresses for pressure relief.
- Back Sleepers: Medium firmness supports the spine while cushioning natural curves.
- Stomach Sleepers: A firm mattress is usually best to prevent misalignment.
Body Weight
- Lighter Individuals (<130 lbs): Often find softer mattresses comfortable, as they don’t sink as deeply.
- Average Weight (130-230 lbs): May prefer medium firmness for balance.
- Heavier Individuals (>230 lbs): Usually benefit from firm or medium-firm mattresses for added support.
Health Needs
- Back Pain: Firm or medium mattresses can help relieve pain by keeping the spine aligned.
- Joint Pain: Softer mattresses may work better for those with joint pain, as they reduce pressure on sensitive areas.
Partner Preferences: If you share a bed, compromise on a medium or hybrid mattress that balances both of your needs. Many companies also offer split firmness options for couples.
Some Bonus Tips for Testing Firmness
Buying a mattress is a big decision, so if you’re testing one in-store, here’s how to make the most of it:
- Lie in Your Usual Position: Lie down in the position you normally sleep in for at least 10-15 minutes.
- Move Around: Try shifting positions to see if the mattress is comfortable for combination sleepers.
- Evaluate Pressure Points: Pay attention to how your shoulders, hips, and lower back feel, especially if you’re a side sleeper.
If you’re shopping online, look for a generous sleep trial—most companies offer at least 100 nights. This trial period lets you experience how the mattress feels in your own home and gives you time to decide if it’s truly comfortable.
Some Common Myths About Soft Medium or Firm Mattresses
Let’s clear up a few myths you might encounter while shopping:
- Myth 1 – Firmer Mattresses Are Always Better for Back Pain: While firm mattresses can be great for support, medium-firm options are often ideal for back pain as they balance support with comfort.
- Myth 2 – Soft Mattresses Are Only for Side Sleepers: While side sleepers do often prefer softer mattresses, lightweight back sleepers can also enjoy the plush feel without losing support.
- Myth 3 – Medium Mattresses Are One-Size-Fits-All: Medium firmness works for many people, but it’s not a perfect fit for everyone. Factors like body weight and sleep style still play a big role.
