Can a mattress topper make a bed more firm?
A mattress topper adds an extra layer of support or comfort to your current mattress. 🥰
They can be an affordable way to improve the feel of your mattress without having to replace it.
Typically, a mattress topper will provide a soft cushioning layer that hugs around the pressure points and softens the feel of a too-firm mattress. ☁️
However, some toppers are made with a firmer feel that can give a soft mattress some extra oomph.

A firm mattress topper can provide a layer of solid comfort that gives your spine some additional support during sleep. 🤗
Should I replace my mattress?
However, a firm mattress topper cannot fix what’s broken. 🛠️

If your current mattress is particularly old and sagging, there is only so much that a very firm mattress topper can do.
Ask yourself:
- Is my mattress older than 7 years?
- Does my mattress have indents and soft spots?
- Does my mattress feel lumpy or have rolls?
If you answered yes to any of those questions, it might be time to invest in a new mattress. 😨

How to choose a firm mattress topper
Choosing a firm mattress topper can feel a bit like searching for a needle in a haystack. 🪡
Typically, mattress toppers come with a soft, body-hugging feel, and it’s not easy trying to find a firm topper.
Likewise, some manufacturers don’t specify a firmness, employing that their topper is universal to every need. 🤔

However, that’s simply not the case.
What to consider before you buy a mattress topper
Mattress toppers come in a range of materials, firmnesses, and depths - each of which will be suited to a specific individual. 🙋♀️
Consider the following criteria:
- What is my sleeping position?
- Do I want a topper to add softness or support to my mattress?
- Should the topper be cool or warm?
- How much do I want to sink into the topper?
- What is my budget?
- Do I need a sleep trial and guarantee?
These factors will depend on your priorities and individual needs for your sleep.
We’ll guide you on all of the above throughout the rest of the article. 👇
Is a softer or firmer mattress topper better?
So, you’ve decided you want an extra firm mattress topper, but what if a soft mattress topper is actually what you need? 🤔
Generally, firmness directly correlates with your sleeping position.
Depending on how you sleep will depend on what firmness level is best.

If you have a partner, you should also consider their sleeping preferences and whether you need a mattress topper just for your side of the bed. 👩❤️👨
What firmness is best for side sleepers?
Sleeping on your side is the most popular sleeping position. 🙌
In fact, 41% of British people like to snooze in this foetal position.
This position puts the most pressure on the hip and shoulder since your entire weight is pressing down into these areas. ⚓

Therefore the mattress or mattress topper should provide a soft to medium feel. ☁️🧸
This allows the material to hug around the joints and relieve pressure.

A soft mattress topper is a particularly good idea for side sleepers who find their mattress too firm. 🥰
What firmness is best for back and stomach sleepers?
Alternatively, back and stomach sleepers need an extra firm mattress topper for a comfy sleep. 😍
This helps keep the spine straight and aligned with the neck throughout the night.

Back sleepers should opt for a medium-firm feel, whilst stomach sleepers should look for firm support. 🧱
Most mattress toppers are soft to medium-firm and generally hug around the body for more adaptive comfort.
Therefore, it’s unlikely that any mattress topper will be suitable for stomach sleepers. 🙁

Instead, consider swapping out your mattress for a firmer choice. 👇
Types of firm mattress toppers
Firm mattress toppers can come in a variety of materials. 🧽🌱🐑
The material of your firm mattress topper will affect how it feels.
Let’s consider the characteristics of those materials below.
🌡️ Temperature
Some materials can absorb body heat or regulate body temperature, whilst others retain heat and keep you warm.

A latex and gel-infused mattress topper will provide an overall cooler sleep as latex is breathable and gel absorbs heat for temperature regulation. ❄️
The type of mattress you sleep on will also affect the overall temperature.
You are more likely to experience overheating on a memory foam mattress, whilst pocket springs provide better circulation. 🌬️

Likewise, sleeping with a lower tog duvet can help you have an overall cooler sleep.
🧱 Firmness
Different materials can come in soft and firm options that provide different comfort levels.

You should also consider your mattress and its firmness level, as this will affect the overall feeling of your sleep.
For example, a soft mattress topper paired with an extra firm mattress will likely create an overall medium-firm level of comfort. 🤯
As a general guideline:
- Soft mattress toppers: memory foam, feather and down, hollowfibre
- Medium to firm mattress toppers: Latex, gel foam, hybrid/pocket springs
However, this is dependent on other factors such as the quality of the material and its structural make-up.
⌛ Lifespan
Some materials last much longer than others.
If you want your topper or mattress to last as long as possible, then you’ll want to invest in the most durable materials. 💪
Our guide on material durability:
Material | Lifespan | We recommend |
Latex | 12 - 15 years | BUY EVERGREEN TOPPER£ 139 |
Feather and down | 8 - 10 years | BUY GOOSE TOPPER£ 125 |
Memory foam | 6 - 10 years | 10% OFF PANDA TOPPER£ 89.96 |
Hollowfibre | 3 - 5 years | BUY DUAL LAYER TOPPER£ 94 |
As you can see, a latex topper is the most durable, but this is also one of the most expensive mattress toppers you can buy.
♻️ Sustainability
As a conscious consumer in a world of mass-produced products, you should also consider your firm mattress topper’s impact on the environment. 🌎
Consider the following:
- How is my product manufactured?
- Is the material recyclable?
- Is the packaging recyclable?
- Will it last a long time?
- Do the materials contain chemicals?
Whilst memory foam is one of the most popular sleeping products in recent years, it’s not the most sustainable. 👎
Polyurethane foam is often manufactured with volatile organic compounds (VOC’s), a chemical gas that can be harmful to you and the environment.
Although they can be made into carpet underlay, they aren’t the easiest material to recycle and often end up in landfills.
Natural fibre products are much more eco-friendly. 👍

Cotton, wool, bamboo and pure natural latex are amongst the best options for sustainability. 🐼🌱🐑
Latex is manufactured from rubber trees that can produce latex sap for up to 30 years and are fully biodegradable.

Likewise, bamboo is a fast-growing crop that uses less water than cotton in the manufacturing process. 💧
However, as these materials are often grown overseas, you should also consider the overall carbon footprint.
You should look for a firm mattress topper that is CERTIPUR-US or OEKO-TEX certified, as the materials have been tested against harmful chemicals. ✔️

How to attach a mattress topper
A mattress topper can be easily attached without any fuss. 🤗
Most mattress toppers come with elastic straps on each corner.
Simply tuck the strap over the corner of the mattress before you add any other bedding.
You should also ensure the firm mattress topper is the right side up, particularly a layered mattress topper. 👀
Can you wash a mattress topper?
Unfortunately, most mattress toppers are not washable. ❌
This is because getting liquid onto materials such as memory foam or gel can damage the fabric.
However, many firm mattress toppers come with washable covers.

You can take the cover off the topper and pop it into the washing machine with your regular bedding. 🧼
You should check the care instructions on your firm mattress topper before removing the cover or washing the topper.
Below are our favourite toppers that are washable or have washable covers!
How long do firm mattress toppers last?
Many mattress toppers come with a guarantee. 🤞
This means you’ll be protected for a specified amount of time against any manufacturing faults.
These faults include material dipping, seams coming apart or any other faults not caused by accidents or general wear and tear. 🛠️

If a fault is found, the mattress topper will usually be replaced with a new one. ✨
The Panda mattress topper comes with a 10-year warranty and a 30-night sleep trial.
What is the best mattress topper for a firm mattress?
The best mattress topper for a too-firm mattress will be soft and body-hugging. 🤗
It will mould around pressure-point areas such as the hips and shoulders and prevent aches and pains.

It will be soft enough to keep the back straight without sinking too much to create a bend in the spine.

Do firm mattress toppers work?
A firm mattress topper is an excellent solution for those who need extra support during sleep.
They’re a great choice for:
- Side and back sleepers
- Those with a mattress under 7 years old
- Those with a thin or soft mattress that is in otherwise good condition
However, even a very firm mattress topper cannot compensate for an old, sagging mattress with indentations or other faults. 👀
Instead, you should consider replacing the mattress altogether.
