Soft, Firm, or Somewhere in Between? How to Find Your Comfort Zone

Many mattress shoppers in the UK and US focus on one word: firmness. But firmness is subjective—and often misunderstood.

A “firm” mattress doesn’t mean uncomfortable, and a “soft” mattress doesn’t mean unsupportive. What really matters is support combined with pressure relief.

• Soft mattresses are ideal for lighter individuals or side sleepers who want a “hugging” feel.

• Medium mattresses are the most popular choice, balancing comfort and support for couples and combination sleepers.

• Firm mattresses suit heavier sleepers or those who need extra support for their back and core.

Your body weight also plays a role. A mattress that feels firm to one person may feel soft to another. That’s why many modern mattress brands now offer trial periods, allowing customers to test comfort at home rather than relying on a quick showroom lie-down.

Good sleep isn’t about choosing the hardest or softest option—it’s about choosing what keeps your body relaxed and supported for 7–8 hours every night.
