Medium-firm mattresses FAQs

Choosing the right mattress firmness can be challenging, and it can directly impact your sleep quality. We've compiled answers to some of our most frequently asked questions to help you make the right choice.

What kind of mattress is medium firm?

A medium-firm mattress is on the firmer end of the support scale, sitting between medium and firm mattresses. It offers plenty of support with a firmer feel that still has some 'give' and can adapt to your body's pressure, meaning it could be the perfect choice if you're looking for exceptional support but a cosy feel.

What types of medium firm mattresses are available?

We have medium-to-firm mattresses for everyone, including some of our best-selling types, such as:

Medium-firm memory foam mattresses

Memory foam mattresses are the ultimate in custom support. Using your body heat, they are designed to mould to your body's unique contours throughout the night. Our range of medium-firm memory foam mattresses provides high levels of support, making them a popular choice with customers.

Medium firm pocket spring mattresses

Perfect for solo sleepers who move around at night or couples, a pocket spring mattress comprises hundreds of springs, each in a fabric pocket. These springs move when weight is placed onto them, meaning springs further away will not move to help reduce unfortunate jostling. Our medium firm pocket spring mattresses combine the benefit of less interruption with a firmer sleeping surface for a good night's sleep!

Medium firm orthopaedic mattresses

This firmness rating is ideal for those suffering from back pain, making a medium-firm orthopaedic mattress the perfect choice for anyone looking to relieve aches and pains. Orthopaedic mattresses are specially designed to reduce joint pressure and are slightly firmer to promote correct spinal alignment. As such, many are rated as medium firm anyway!

Want to learn more about the different types we have available to buy? Our mattress buying guide goes in-depth to make shopping easier than ever.

Are medium-firm mattresses good for back pain?

Yes, a medium-firm mattress is a good choice if you suffer back pain, as studies have shown that people with long-term back pain who slept on medium-firm mattresses suffered less pain than those who slept on soft mattresses.

They are soft enough to be comfortable but firm enough to promote healthy spinal alignment as you sleep. This helps reduce the risk of aches and pains while relieving pressure on your joints. To learn more, check out our guide on the best mattresses for back pain or explore our curated range of back-pain mattresses!

What sizes can I buy a medium-firm mattress in?

We have a medium to firm mattress for everyone and every bedroom, with our range including all the most popular sizes:

  • Medium-firm, small single mattress
  • Medium-firm single mattress
  • Medium-firm small double mattress
  • Medium-firm double mattress
  • Medium-firm king-size mattress
  • Medium-firm super king-size mattress

We also offer this firmness rating in European sizes, including European singles and doubles! Not sure which size is right for you? Our mattress size guide explains the different sizes.
