Firm mattresses offer plenty of great benefits, particularly for those who are heavier or prefer to sleep on their front or back. They have high levels of support, making them ideal for alleviating back pain. As the name suggests, it will feel very 'firm' to the touch with minimal give and will evenly distribute your body weight, whereas a softer mattress is more likely to have you 'sink' into it.

If you're looking for the highest level of support, there are also extra-firm mattresses. These are ranked at the top of the firmness scale, but this also means they might not have some features that can make them a little more comfortable, such as foam.

Firm mattresses feel like your body is being supported or 'held up' so you won't sink. Instead, you should feel like you are lying on top of the mattress and not like you're falling into it. As you might expect, this can make changing sleeping positions much easier!

Individuals who can experience the most benefit from a firm mattress will be those who sleep on their front or back. These positions can often lead to incorrect spinal alignment, resulting in aches and pain during the day. A firm mattress forces your body to rest correctly, relieving pressure on your spine and joints.

Others who will benefit are those who are heavier, experience back pain, or have mobility issues. The firmer surface of these mattresses will benefit heavier people, as it prevents the risk of sinking in and making it too hard to move around or causing aches and pains.

Our firm mattresses are available to buy in the following types:

Firm memory foam mattresses

A firm memory foam mattress offers ultimate customised support. The memory foam construction uses body heat to mould to your unique contours during the night. The firm rating means you get the highest level of support, helping to relieve pressure on your joints and reduce the risk of aches and pains.

Firm pocket spring mattresses

Our firm pocket spring mattresses combine comfort and support to ensure you sleep well every night. Each spring is contained in an individual fabric pocket that allows them to work independently from each other, reducing any extra movement during the night. This makes a firm pocket spring mattress ideal for couples or anyone who moves a lot at night!

Firm orthopaedic mattresses

An orthopaedic mattress is designed to offer high levels of support to reduce the risk of aches and pains, making it particularly suitable for those suffering from back pain. A firm orthopaedic mattress promotes healthy spinal alignment by reducing joint pressure, making it a favourite of people with back pain.
