Advice and buying guides
What does medium firm mattress mean?
A medium-firm mattress provides a great balance between just enough "give" and plenty of support. It's a firmness rating that sits in-between medium and firm. Medium-firm mattresses are perfect if you prefer a slightly firmer feel, but with plenty of cushioning comfort too.
What's the best medium firm mattress?
Here are 3 factors to think about when deciding which medium firm mattress is best:
- The best selling
- The most premium
- The best reviewed
The best selling premium medium firm mattress
Our best selling premium medium firm mattress is the Classic Gold Ortho. The Classic Gold Ortho offers support and comfort at a very reasonable price.
The most premium medium firm mattress

Is a medium firm mattress good?
A medium-firm mattress is a great choice if you're looking for plenty of support without sacrificing comfort. It's a good all-round mattress for many sleeping positions - particularly if you sleep on your back, front, or if you change position as you sleep. A medium-firm mattress is also best if you find it difficult to choose between a medium or a firmer feel.
