Mattress Buying Guide: Comfort, Support & Custom Fit
How to Choose Your Ideal Mattress Firmness
When it comes to buying a new mattress, there’s no one-size-fits-all solution. Your perfect mattress depends on your sleeping style, body type, health needs, and personal comfort preferences. At Pure Sleep, we believe your bed should be tailored to you, whether you choose from our expertly pre-designed range or create a custom-made mattress from scratch.
A well-chosen mattress can:
- Improve sleep quality
- Reduce aches and pains
- Support healthy spinal alignment
- Last for years without losing comfort
This guide will walk you through the key considerations when selecting your mattress—plus help you understand mattress firmness and which option might be right for you.
1. Determine Your Sleep Position
Side sleepers need pressure relief for shoulders and hips—aim for soft to medium-soft.
Back sleepers benefit from medium-firm to firm support for spinal alignment.
Stomach sleepers should choose firm options to prevent sinking at the waist.
2. Consider Your Body Weight
3. Use the 1–10 Firmness Scale as a Guide
Most mattresses rate firmness on a scale from 1 (very soft) to 10 (very firm).
1: Extra Plush – Highly plush, minimal support, best for niche comfort preferences
2–4: Soft—excellent for side sleepers and smaller builds.
5–7: Medium—offers a balanced feel ideal for mixed sleep positions.
8–10: Firm—best for stomach sleepers or those needing firm lumbar support
4. Think About Partner Comfort
If you share your bed with someone, consider options like split-firmness or custom mattresses that accommodate each partner’s preferred feel. Explore our Side by Side 50/50 mattress here.
How Mattress Firmness is Categorised
Mattress firmness is typically measured on a scale from 1 to 10, giving you an easy way to compare comfort levels across different styles and brands.
On this scale, 1 represents the softest, most plush feel, while 10 is the firmest option available.
EXTRA PLUSH COMFORT (1)
The softest comfort level available, offering a cloud-like, sink-in feel. Ideal for side sleepers or those who want maximum pressure relief and a luxurious, enveloping surface.Soft COMFORT (2–4)
Deep cushioning that contours closely to your body, ideal for lighter-weight sleepers and side sleepers who need extra pressure relief.
Medium COMFORT (5–7)
A balanced blend of softness and support, making it the most popular choice for couples and people who change positions during the night.
Firm Comfort (8–10)
A more supportive surface with minimal sink, recommended for back and stomach sleepers or those who prefer a sturdier feel.
Comfort Layers vs. Base Support
Understanding Mattress Construction
A great mattress is more than just “soft” or “firm.” It’s built from layers that each play a different role in how the bed feels and supports you.
Comfort Layers
The comfort layers are the top sections of the mattress, designed to provide cushioning, pressure relief, and that initial “ahh” feeling when you lie down. These layers may be made from materials like memory foam, latex, gel-infused foam, or plush quilting. They contour to your body, absorb pressure from your shoulders and hips, and influence how soft or firm the mattress feels at the surface.
Base Support
Beneath the comfort layers is the support core—sometimes called the base layer. This section is what keeps your spine aligned and prevents the mattress from sagging over time. It’s typically made from high-density foam or a spring system, such as pocket springs or Bonnell springs. The base doesn’t feel as plush, but it’s essential for durability and structural support.
Why It Matters
Understanding the difference between comfort and support is key when choosing a mattress. The comfort layers determine how a mattress feels to touch, while the base ensures your body is properly supported night after night. For the best sleep, you need both working together; comfort for pressure relief and support for healthy alignment.
