How to choose the right mattress firmness

Choosing the right mattress firmness is essential for a good night’s sleep, supporting your body, and preventing aches and pains. With so many options available, it can feel overwhelming, but understanding mattress types and how firmness suits different body types makes the decision much easier.

Understanding mattress firmness levels

Mattress firmness is typically rated on a scale from soft to extra firm. Pocket sprung mattresses are particularly popular because each spring works independently to support your body, reducing pressure points and improving comfort. It's important to note that firmness can vary between each mattress company. For example, a medium mattress from The Yorkshire Mattress Co., may feel different to a medium mattress from someone else. Here's a breakdown of the main firmness options:

1. Soft pocket sprung mattress

A soft pocket sprung mattress is ideal for lighter individuals or those who prefer a plush, hugging feel. The mattress allows your body to sink slightly, cradling your body and reducing pressure on your shoulders and hips. For heavier body types, a soft mattress can feel comfortable and luxurious at first, but over time it may not offer your body the support and pressure relief it needs.

Best for: People weighing up to 11 stone (70kg) or those who enjoy a softer sleeping surface.

Pros: Gentle on joints, great for side sleepers, provides a luxurious feel.

Cons: May lack support for heavier individuals, causing the body to sink too deeply.

2. Medium soft pocket sprung mattress

The medium soft pocket sprung mattress is slightly firmer than a soft mattress but still provides a gentle, comfortable sleep surface. It’s perfect if you want a balance between softness and support.

Best for: People around 11–13 stone (70–82kg) or those who prefer a cozy feel without losing support.

Pros: Comfortable for side sleepers, provides moderate support, reduces pressure points.

Cons: Might not offer enough support for heavier sleepers or those who prefer a firmer feel.

3. Medium pocket sprung mattress

A medium pocket sprung mattress is a versatile choice suitable for most sleepers. It provides enough firmness to support the spine while remaining comfortable for side and back sleeping positions.

Best for: People weighing 11–16 stone (70–102kg).

Pros: Balanced support and comfort, suitable for couples with different sleeping preferences. A medium mattress is usually the go to preference for most sleepers.

Cons: May feel slightly firm for very light weight sleepers or soft mattress enthusiasts.

4. Medium firm pocket sprung mattress

The medium firm pocket sprung mattress offers extra support for the spine, making it a popular choice for back and combination sleepers. It is firmer than medium mattresses but not overly hard.

Best for: People weighing 16–20 stone (102–127kg).

Pros: Supports heavier body weights, maintains spinal alignment, durable over time.

Cons: Might feel too firm for lighter sleepers.

5. Firm pocket sprung mattress

A firm pocket sprung mattress provides maximum support, particularly for heavier individuals or those who prefer a solid sleeping surface. It reduces sagging and ensures proper posture throughout the night.

Best for: People weighing 20+ stone (127kg+) or those who need extra support for back or stomach sleeping.

Pros: Excellent spinal support, long-lasting firmness, ideal for heavy weight sleepers.

Cons: May feel too hard for side sleepers or those who prefer a soft, cushioned mattress.

Final Tips

• Test before you buy: If you can make it to our mattress showroom in Thirsk (at our sister company, Furniture Traders), we'd always recommend trying our mattress range in person. Once you find a mattress you like the feel of, lie down on it in your natural sleeping position for around 10 minutes. Our in-store sleeping experts can also help you find the perfect mattress.

• Consider sleeping position and your weight: Side sleepers often prefer softer mattresses, while back or stomach sleepers may benefit from firmer support. The higher the spring count, the more responsive and pressure relieving your mattress will be.

• Think about mattress fillings: Fillings also help with the support and longevity of you mattress. Natural fillings offer several benefits including natural temperature control, ventilation and great pressure relief.
