Choosing a new mattress is about more than size and price. One of the most important factors is mattress firmness. The right firmness can make your bed feel more comfortable and provide the level of support you need throughout the night.
Your sleeping position is a useful starting point when deciding which mattress firmness may suit you best.
Best Mattress Firmness for Side Sleepers
Side sleepers usually place more pressure on their shoulders and hips. A mattress that provides some cushioning while still offering sufficient support can help create a more comfortable sleeping surface.
A medium or medium-firm mattress can be a good option for many side sleepers, offering a balance between cushioning and support.
Best Mattress Firmness for Back Sleepers
Back sleepers generally benefit from a mattress that provides stable support while allowing the natural curves of the body to remain comfortable.
A medium-firm to firm mattress may be suitable for back sleepers who prefer a more supportive feel. However, comfort is personal, so your own preference should also be considered.
Best Mattress Firmness for Stomach Sleepers
Stomach sleepers may prefer a firmer sleeping surface. A mattress with stronger support can help prevent the body from sinking too deeply into the mattress.
For this reason, firm mattresses are often worth considering if you mainly sleep on your stomach.
What About Combination Sleepers?
If you change positions throughout the night, choosing a mattress with a balanced feel can make it easier to move comfortably.
A medium-firm mattress can be a versatile option for combination sleepers because it provides a balance between support and comfort across different sleeping positions.
Medium-Firm Mattresses: A Versatile Choice
If you are unsure which firmness level to choose, medium-firm is often a good starting point. It offers a balance between a softer, cushioned feel and the stability of a firmer mattress.
At iSleep, the iSleep ONE Hybrid Mattress has a medium-firm feel of approximately 5–6.5/10 and combines pocket spring support with comfort layers for a balanced sleeping experience.
For sleepers who prefer a firmer feel, the iSleep Edge Mattress offers a firmer support level and enhanced edge support.
Don't Forget Your Personal Comfort
There is no single mattress firmness that is perfect for everyone. Your sleeping position, preferred feel, bedroom setup and personal comfort preferences should all be considered when choosing a mattress.
If you are buying a mattress online, a sleep trial can also give you more time to decide whether the firmness feels right in your own home.
