Comfort & Firmness Guide
Understand mattress comfort levels, firmness, and how to choose the right feel for your sleep.
Comfort & Firmness Basics
Understanding Mattress Comfort & Firmness
Choosing the right mattress comfort level is one of the most important decisions when buying a mattress. Comfort affects sleep quality, posture, support, pressure relief, and long-term wellbeing.
Soft Comfort Mattress
Soft mattresses provide a cushioned feel with gentle sink-in comfort. Best for side sleepers, lightweight sleepers, and those who prefer pressure relief around hips and shoulders.
Medium Comfort Mattress
Medium comfort mattresses provide balanced support and softness. They are ideal for combination sleepers and couples.
Medium Firm Mattress
Medium firm mattresses offer stronger support while still maintaining comfort. They are often recommended for spinal alignment and posture support.
Firm Mattress
Firm mattresses provide a supportive sleep surface with minimal sinkage. Suitable for back sleepers, stomach sleepers, and heavier body types.
Mattress Comfort By Sleeping Position
Different sleeping positions require different support levels. Side sleepers often prefer softer comfort, while back and stomach sleepers usually benefit from medium firm or firm mattresses.
Memory Foam Mattresses
Memory foam mattresses contour to the body and help reduce pressure points.
Pocket Spring Mattresses
Pocket spring mattresses provide responsive support through individually wrapped springs.
Orthopaedic Mattresses
Orthopaedic mattresses are designed to support posture and spinal alignment.
Hybrid Mattresses
Hybrid mattresses combine foam layers with spring systems for balanced comfort and support.
Mattress Firmness Scale
Soft: 1–3/10
Medium: 4–6/10

Firm: 8–10/10
How To Choose The Right Mattress Comfort Level
Consider sleeping position, body weight, personal comfort preference, and support needs.
Why Mattress Comfort Matters
Mattress comfort directly affects sleep quality, recovery, posture support, and long-term comfort.
Spring Count
Spring Count Explained
Spring count refers to the total number of individual springs inside a mattress. In general, a higher spring count can provide more responsive support and better weight distribution, helping the mattress adapt more precisely to your body.
Pocket sprung and hybrid mattresses often use individual springs that move independently, which helps reduce motion transfer and improves comfort for couples.
Does a Higher Spring Count Mean Better Quality?
Not always. While a higher spring count can improve support and comfort, it’s only one factor. The quality of the springs, the materials used above them (such as memory foam or fillings), and the overall construction of the mattress are equally important.
A well-made 1000 spring mattress can outperform a poorly constructed 2000 spring one.
Spring Count and Mattress Size
Spring count varies depending on mattress size. Larger mattresses naturally contain more springs than smaller ones.
For consistency, spring counts are typically quoted based on a King size (5ft) mattress.
For example:
- A King size mattress may have 1500 springs
- The same model in Double or Single will have fewer springs
- The same model in Super King will have more springs
Despite this, the overall comfort and support level remains consistent across sizes.
What Spring Count Should I Choose?
- 1000–1500 springs (King size equivalent): Balanced support, suitable for everyday comfort
- 1500–2000 springs: Enhanced support and pressure distribution
- 2000+ springs: More responsive support and a more premium feel
Your ideal choice depends on your comfort preference, body weight, and sleep position rather than spring count alone.
Key Takeaway
Spring count is a useful guide, but it should always be considered alongside comfort layers, firmness level, and overall mattress design.
