Firm Mattresses

What are the benefits of a firm mattress?

A firm mattress provides several benefits, including:

• Solid support: With less compression underweight, firm mattresses give you a firmer sleeping surface, providing support while sleeping.
• Spinal alignment: Sleeping on a firm mattress helps to maintain a neutral spine, making them great mattresses for back pain and improving posture.
• Pressure relief: They help alleviate pressure on key areas such as the back, shoulders, and hips by preventing the body from sinking too deeply.
• Even weight distribution: Firm mattresses are better at evenly distributing weight for heavier individuals and couples, and are less prone to sagging or sinking. Those with a heavier build may benefit more from a very firm mattress.

What sleeping position are firm mattresses best for?

Firm mattresses are great for a wide range of sleeping positions, including back, stomach and combination sleepers. This is because a firm mattress supports and maintains proper spinal alignment, preventing back pain and the lower back from arching. They also ensure that your body remains properly supported if you change positions as you sleep.

However, if you are a side sleeper, you may find that a firm mattress is too hard and doesn’t offer as much cushioning as you need. To help you pick the right one for you, browse our mattresses by sleeping position or read our guide to find the best sleeping position for you.

Are firm mattresses good for those with back pain?

Yes, a firm mattress can make a real difference if back pain is keeping you up at night. By keeping your spine in a neutral position, a firm surface stops your lower back from sinking and straining through the night. That said, it's not a one-size-fits-all situation or a cure for ongoing back pain with an underlying cause. The right firmness for you depends on your sleeping position, build, and the type of back pain you're dealing with. For a closer look at how your mattress choice affects your back, read our guide to sleeping with back pain, or discover more tips on how to prevent back pain in bed.

What extra firm mattress fillings can I choose from?

Our firm mattresses come with a variety of fillings, such as:

• Pocket spring firm mattresses: Individually wrapped springs provide support and reduce motion transfer. They’re a solid choice for back and stomach sleepers who need consistent, even support throughout the night.
• Memory foam firm mattresses: Provide pressure-relieving comfort which contours to your body. Firm memory foam is particularly good for those with back pain, as it moulds to your shape and helps reduce pressure on the spine.
• Combination firm mattresses: A mix of springs and foam offering a balance between firm support and comfort. Ideal for combination sleepers who switch positions through the night.
• Traditional spring firm mattresses: Offer firm spring support at a more affordable price. They’re best suited to back and stomach sleepers who want straightforward, no-fuss support.
• Natural firm mattresses: Made with naturally anti-allergy, antibacterial, and more eco-friendly firm fillings, such as wool or cotton; a great option for back sleepers who want natural comfort without compromising on support.
• Latex firm mattresses: A firmer and more responsive surface with naturally cooling features. Firm latex mattresses are well-suited to stomach sleepers and those with back pain who need a surface that pushes back and keeps the spine aligned.
• Gel firm mattresses: Great for hot sleepers who need firm support, these offer a cooling effect. They’re popular with back sleepers who tend to overheat.
