Why do some people prefer a firmer mattress?

There are a number of reasons people might prefer a firmer mattress. Maybe you’ve had a back injury and need extra support for your spine and joints, or perhaps you just like the feeling of being cradled without sinking too deeply into your mattress.

Whatever your reasons, there are a few ways to achieve that added firmness. We’ll get to those in a minute but first, let’s address the concept of mattress firmness. 

How do I know if my mattress is soft or firm?

There are a few tell-tale signs that you might need to firm up your mattress. If you find yourself constantly tossing and turning, struggling to find a comfortable position, waking up with aches and pains, or being hot and sweaty, then your mattress is likely too soft.

When shopping for a new mattress, it’s important to keep in mind that different people have different preferences. If you’re unsure whether you prefer a soft, medium or firm mattress, it’s always best to err on the side of firmness. You can always add a firm mattress topper later if you find it’s not quite firm enough for your liking.

What does a firmer mattress feel like?

A firmer mattress generally offers less sinkage and a more supportive feel. This can be beneficial for those who need extra support for their back or joints or for people who just prefer a firmer sleeping surface.

Firmer mattresses also tend to sleep cooler than softer options, as there is less body contact with the mattress itself. This can be a plus for those who sleep hot or live in warmer climates.

Of course, firmness is subjective, so what feels firm to one person may not feel the same to another. It’s important to find a mattress that strikes the perfect balance of firmness and comfort for you.

Thankfully, there are a few ways to make your bed feel firmer, which you can try at home right now!

Tips on how to make your soft mattress firmer

1. Add a mattress topper

One of the easiest and most effective ways to firm up your mattress is to add a firm mattress topper. Mattress toppers are thick layers of material that sit on top of your existing mattress, providing additional support and firmness.

There are a variety of different materials you can choose from, including memory foam, latex and wool. Memory foam is a popular firm mattress topper as it moulds to your body, providing support for your spine and joints.

2. Flip your mattress

If your mattress has a pillow top or is starting to sag in the middle, flipping it over can help give it a new lease on life. This will redistribute any sagging filling and even out the surface of your mattress, making it feel firmer and more supportive.

3. Place a board under your mattress

If you don’t want to invest in a new mattress topper, you can try placing a plywood board under your mattress. This will provide extra support and firmness and can be especially helpful if your mattress is sagging in the middle.

4. Use a firmer pillow

If you find your head sinking too deeply into your pillow, it might be time to switch to a firmer option. A firmer pillow will provide more support for your head and neck, helping to keep your spine in alignment.

5. Try sleeping on the floor

This one is a bit of a last resort, but it can actually be surprisingly comfortable! Sleeping on the floor will give you a firmer surface to sleep on than your ‘too soft’ mattress – however, we wouldn’t recommend this as a long term solution.

Sleeping on the floor will not provide your body with the optimal comfort and support it needs for a good night’s sleep.

6. Adjust your bedding

Your bedding can also affect how firm or soft your sleeping surface feels. Heavier blankets and sheets will make your mattress feel softer, while lighter options will make it feel firmer.

A fitted sheet and a thin duvet or comforter can help to make your mattress firmer. This will provide a firm surface to sleep on without making you too hot.

7. Replace the bed frame

The bed frame can also make a mattress feel firmer. Bases with solid timber slats tend to provide more support than those with a box spring system. This is because they distribute weight evenly, preventing the mattress from sagging in the middle.

8. Add legs to the bed frame

If you’re using a bed frame with legs, adding an extra set of legs in the middle can help to firm up your mattress. This will provide extra support and prevent the mattress from sagging.

9. Check if your mattress is damp

If your mattress is feeling particularly soft, it’s worth checking if it’s damp. This can happen if there’s a leak in the bed or if you live in a humid climate. Dampness can cause the mattress to sag and become less supportive.

If you think your mattress might be damp, try using a dehumidifier to remove any excess moisture. You can also place a fan in the room to help circulate the air or consider taking your mattress outside to air in the sun.

10. Use a mattress protector

If you want to firm up your mattress but don’t want to make any permanent changes, using a mattress protector is a good option. This will add an extra layer of support and firmness to your mattress, and can be easily removed if you find it’s not for you.

Hopefully these tips will help you get a better night’s sleep. Remember, the most important thing is to find a mattress that is comfortable for you. If you’re unhappy with your current mattress, you might consider replacing it with a high-quality firm mattress that is sure to provide you the support you’re looking for.
