Step 1. Swap it for a softer mattress

Consult the booklet your mattress came with to see if your mattress has a sleep trial and if it's still valid. If after sleeping on the mattress you think you'd benefit from a softer option, you could exchange it.

Step 2. Break it in

Brand new mattresses often start off a little firmer than you might anticipate, so you need to sleep on them to give them a chance to soften up. This is because sleeping on the mattress helps to distribute the fillings and make the mattress more comfortable overall.

This is one of the reasons why a lot of mattresses come with a sleep trial because it gives the mattress time to adjust. You can trial some new mattresses for up to 1 year to work out whether it's right for you - and swap it for a different one if it's too firm!

Some types of mattress, such as a memory foam mattress, responds to body heat which can make them feel softer. This means it might feel more comfortable after sleeping on it for a few hours.

Step 3. Buy a softer mattress topper

Investing in a mattress topper is the most popular and immediate solution to make your firm mattress softer. Toppers sit on the surface of your mattress and can provide extra comfort for your mattress.

A topper with a softer firmness rating will instantly make your mattress feel more comfortable.

Step 4. Flip your mattress

You should check your mattress' care guide to see if it needs rotating and how often. Turning your double-sided mattress on a regular basis helps to keep your mattress comfy and can even improve the lifespan of your mattress.

Turning your mattress helps to keep the comfort fillings evenly distributed which keeps your mattress at the ideal firmness. If you're not sure how often you should turn your mattress, check out our helpful guide.

Step 5. Replace your bed frame or slats

Check your bed frame to see what kind of slats you have. Solid slats make your mattress feel a lot firmer as they are designed to offer more support by adding pressure to your mattress.

To make your mattress softer, you could invest in a bed frame with sprung slats. This is because sprung slats provide more cushioned support and move with your mattress throughout the night.

Step 6. Invest in a new divan base

A solid platform base will make your mattress feel a lot firmer. This is because the solid, flat surface provides a lot more support for your mattress but has no 'give'.

We suggest replacing the solid base with a sprung base because they offer more plush support. This is because the base gently cradles the mattress while you sleep rather than a sturdy flat surface.

Step 7. Make your room warmer

memory foam mattress is temperature-sensitive. Since these types of mattress respond to heat, you could try making your bedroom a little warmer. This could help soften your mattress.

If you don't want to change the temperature of your whole room, you could put a hot water bottle under your duvet before you go to sleep. This will help to soften your mattress before you lie on it and it'll make your sleeping experience extra cosy.

Step 8. Change your sleeping position

An easy way to make a hard mattress softer is to change how you sleep. Changing your sleeping position can make your mattress firmness feel different.

If your mattress feels too hard, you could try sleeping on your front or back. This is because some firmness ratings are more suited to certain sleeping positions to properly support your joints.

You can find out more about the best mattresses for different sleeping positions in our guide.

Step 9. Invest in a softer mattress

If you think your mattress is too firm for any of these steps to provide long-term results, it might be time to invest in a new mattress.

Ideally, your mattress should be replaced every seven years so you can always get a great night's sleep. However, if your mattress is damaged or lumpy or is too uncomfortable to sleep on, investing in a softer mattress is the best option.
