Soft Mattresses

What are the benefits of a soft mattress?

Soft mattresses are great for those who love a more cushioned, cosy feel and come with several benefits, including:

• Pressure relief: Soft mattresses contour closely to the body, especially at the shoulders and hips, which helps relieve pressure in those areas, making them ideal for side sleepers.
• Comfortable cushioned feel: They offer a soft, cradling feel that’s both cosy and tailored to your body, perfect for lighter individuals who may not sink as comfortably into firmer mattresses.
• Spinal alignment: Soft mattresses support proper spinal alignment for side sleepers, particularly by allowing the curves of the body to sink into the surface, supporting their natural structure.
• Motion isolation: Soft memory foam and latex mattresses help to absorb movement, great for couples who don’t want to disturb one another.
• Alleviates pain: People with joint or muscle pain around the shoulders and hips may find that a soft mattress helps to ease discomfort due to its cushioning feel.
• Supports growth: A soft mattress is ideal for growing children, offering the perfect level of support for little bodies and helping to keep their spines aligned through the night.

Is a soft mattress suitable for side sleepers?

Yes. A soft mattress is ideal for side sleepers as it lets your shoulders and hips sink in, keeping your spine straight. Find more tips on what to look out for in our guide to the best mattresses for side sleepers.

Is a soft mattress suitable for back sleepers?

It depends on your weight. Lighter back sleepers (under 9 stone) often like a soft mattress. Heavier bodies can sink too far at the hips, so a medium mattress gives better support. Our back sleeping guide explains more.

Is a soft mattress suitable for front sleepers?

Usually not. A soft mattress lets your hips dip, which can arch your lower back by morning. Front sleepers tend to suit a firm mattress. Lighter front sleepers can be the exception. Our guide to the best mattresses for front sleepers has more details.

Is a soft mattress bad for your back?

A soft mattress itself isn’t bad for your back. However, it depends on whether it’s the right fit for you. A soft mattress that suits your weight and sleeping position keeps your spine in line and eases pressure. Problems start when it's too soft for you, letting your hips sink and your back curve.

How to make a soft mattress firmer

If a soft mattress gives too much sink for you, a firm mattress topper could help. A dense foam or latex mattress topper can add a firmer feel straight away. Check your base too. Saggy slats or an old divan can make any mattress feel softer, so a solid divan bed base or slatted frame with narrow gaps helps. Rotating your mattress regularly also keeps it even.

What is the highest-rated soft mattress?

Each of our soft mattresses displays its customer rating, making it easy to find the highest-rated option. But the best soft mattress for you won't always be the one with the most stars. It depends on how you sleep, your weight and build, whether you share your bed, if you run hot, and what you want to spend. A side sleeper who runs warm might love a soft gel mattress or one from our cooling mattress range. A lighter back sleeper may prefer the bounce of pocket springs. To find the best one for you, try our Sleepmatch in store, which maps your body in just three minutes.
