How Firm Should My Mattress Be?

There's no one answer for how firm your mattress should be. Instead, you should match your comfort grade of choice to your sleeping position, habits, and even things like your weight or if you share a bed with a partner. To learn more about which level of comfort you should choose, read our guide on the best mattresses for your sleeping position.

Who Are Firm Mattresses Best For?

Clearly, firm mattresses are great for those who like a high level of support throughout the night. However, they're also recommended for:

  • Back-sleepers and front-sleepers
  • Couples who share a bed and suffer from roll-together moments
  • Those who are above average weight
  • Sufferers of back-pain

If you sleep on your side, you may be better considering a medium mattress — these are better at responding to pressure points such as shoulders and hips.

What Are The Different Types Of Firm Mattress?

Memory Foam

Memory foam mattresses respond to the shape of your body. They do this by allowing air through the viscoelastic and polyurethane cells, giving the mattress enough flexibility to form around your body's natural sleeping position.

Pocket Spring

Pocket spring mattresses are those which have individual springs in individual pockets right across the entirety of the mattress. This makes them ultra-responsive and also helps make sure it's only the part of the mattress that you lie on that responds to the shape of your body.

Traditional Spring

Traditional spring mattresses are a real budget-friendly option. They're a little similar to pocket-spring except the springs are linked to each other, rather than sitting in individual pockets. They can still be extremely comfortable and are great for those who don't want to spend too much.

Hybrid mattresses, as the name suggests, are those which blend a range of mattress technologies. Look out for latex and gel if you like to keep cool. For those who like a little extra comfort, consider a pillowtop. If you suffer from back pain or just want guaranteed support, check out our very frim products which offer a blend of supportive spring systems, memory foam, and TENCEL™ fibres to help reduce moisture and allergens.
