How to Choose the Right Mattress Firmness Based on Your Sleeping Position

How to Choose the Right Mattress Firmness Based on Your Sleeping Position

Choosing a new mattress isn't just about finding one that feels comfortable in the showroom—it's about finding the right firmness that supports your body throughout the night. Your preferred sleeping position plays a major role in determining which mattress firmness will provide the best balance of comfort, pressure relief, and spinal alignment.

At Restezzzy Mattresses, we help customers across Saskatoon, Warman, Martensville, Langham, and Dalmeny find the perfect mattress based on their unique sleeping habits. Whether you're a side sleeper, back sleeper, stomach sleeper, or someone who changes positions during the night, understanding mattress firmness can help you make a better investment in your sleep.


Understanding Mattress Firmness

Mattress firmness describes how soft or firm a mattress feels when you lie on it. It is commonly measured on a scale from 1 to 10:

  • 1–3: Soft
  • 4–6: Medium to Medium-Firm
  • 7–8: Firm
  • 9–10: Extra Firm

Keep in mind that firmness is different from support. A quality mattress should provide excellent support regardless of whether it feels plush or firm.


Best Mattress Firmness for Side Sleepers

Side sleeping is one of the most common sleep positions. However, it places more pressure on your shoulders and hips than other positions.

Recommended Firmness:

Medium Soft to Medium (4–6)

A softer comfort layer allows your shoulders and hips to sink slightly while keeping your spine properly aligned.

Benefits

  • Better pressure relief
  • Reduced shoulder pain
  • Less hip discomfort
  • Improved blood circulation

Ideal Mattress Types

  • Memory Foam
  • Hybrid Mattresses
  • Plush Pocket Coil Mattresses

Best Mattress Firmness for Back Sleepers

Back sleepers require balanced support that keeps the spine in its natural position.

Recommended Firmness:

Medium Firm (5–7)

A mattress that's too soft may allow the hips to sink too deeply, while one that's too firm can create pressure around the lower back.

Benefits

  • Proper spinal alignment
  • Even weight distribution
  • Lower back support
  • Reduced muscle tension

Ideal Mattress Types

  • Hybrid Mattresses
  • Pocket Coil Mattresses
  • Medium-Firm Foam Mattresses

Best Mattress Firmness for Stomach Sleepers

Sleeping on your stomach can place extra stress on your lower back if your hips sink into the mattress.

Recommended Firmness:

Firm (7–8)

A firmer mattress keeps your hips elevated and helps maintain better posture while sleeping.

Benefits

  • Prevents excessive hip sinking
  • Supports spinal alignment
  • Reduces lower back strain

Ideal Mattress Types

  • Firm Pocket Coil
  • High-Density Foam
  • Firm Hybrid Mattresses

Best Mattress Firmness for Combination Sleepers

Combination sleepers move between multiple sleeping positions during the night.

Recommended Firmness:

Medium to Medium Firm (5–6)

This provides enough cushioning for side sleeping while maintaining support for back and stomach positions.

Benefits

  • Comfortable in multiple positions
  • Easier movement
  • Balanced support
  • Better overall comfort

Ideal Mattress Types

  • Hybrid Mattresses
  • Responsive Pocket Coil Mattresses

What About Body Weight?

Your body weight also affects how firm a mattress feels.

Under 60 kg

Lighter sleepers don't compress the mattress as much, so a softer mattress often feels more comfortable.

60–90 kg

Most sleepers in this range are comfortable on medium to medium-firm mattresses.

Over 90 kg

Heavier individuals generally benefit from medium-firm to firm mattresses that provide better support and durability.


Common Mattress Firmness Mistakes

Avoid these common mistakes when shopping for a mattress:

  • Choosing the firmest mattress because you think it's better for your back.
  • Buying the softest mattress simply because it feels luxurious in the store.
  • Ignoring your sleeping position.
  • Forgetting to consider body weight.
  • Focusing only on firmness instead of overall support and mattress quality.

How to Test Mattress Firmness

When testing a mattress:

  • Lie in your usual sleeping position for at least 10–15 minutes.
  • Pay attention to pressure around your shoulders, hips, and lower back.
  • Check whether your spine feels naturally aligned.
  • Roll over to see how easily you can change positions.
  • If shopping with a partner, test the mattress together to assess motion isolation and overall comfort.

Why Hybrid Mattresses Are a Great Choice

Hybrid mattresses combine responsive pocket coils with premium comfort foams, making them an excellent option for many sleepers.

They offer:

  • Excellent pressure relief
  • Strong edge support
  • Better airflow for cooler sleep
  • Reduced motion transfer
  • Support suitable for a wide range of sleeping positions

That's why hybrid mattresses are among the most popular choices for Canadian households.
