Can a mattress topper make a bed more firm?
Are you in search of a mattress topper to make your bed firmer?
A mattress topper typically adds a 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 (such as your hips and shoulders) 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 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 a very firm mattress topper can do.
- 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. 😨
Our guide on the best mattresses explores the most suitable bed for your sleeping position.
Firm mattress topper buying guide
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.
Consider the following:
- 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 individual needs for your sleep.
Our buying guide below can help you find the perfect mattress topper for your requirements. 👇
Some materials can 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.
Likewise, sleeping with a lower tog duvet can help you have a cooler sleep.
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 a medium-firm level of comfort. 🤯
As a general guideline when choosing mattress topper materials:
- Soft mattress topper materials include memory foam, feather and down, hollowfibre
- Medium to firm bed topper materials include Latex, gel foam, hybrid/pocket springs
However, this also depends on other factors, such as the quality of the material and its structural makeup.
Some materials last much longer than others.
You’ll want to invest in the most durable materials to ensure your mattress or topper lasts. 💪
Our guide on material durability:
|Latex||12 - 15 years|
|Feather and down||8 - 10 years|
|Memory foam||6 - 10 years|
|Hollowfibre||3 - 5 years|
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.
As a conscious consumer in a world of mass-produced products, you may be interested in your firm mattress topper’s impact on the environment. 🌎
- 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 has become one of the most popular sleeping products in recent years, it’s not the most sustainable. 👎
Memory foam is a type of polyurethane foam that is often manufactured with volatile organic compounds (VOCs), a chemical gas that can harm you and the environment.
In addition, 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 natural latex are the best sustainability options. 🐼🌱🐑
Latex is manufactured from rubber trees that can produce latex sap for up to 30 years and is 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.
The foam used in the Simba topper is CertiPUR-certified, ensuring it contains no TCPP, phosphates, parabens, biocides, or other harmful chemicals.
How much are firm mattress toppers?
Firm mattress topper prices vary. 💰
Typically, a mattress topper will cost anywhere from £100 or more depending on your size.
Generally, the more you spend, the better the quality of the topper.
However, some toppers are fantastic value for money. 🤯
The Inofia Gel mattress topper is an excellent option for those who need a firm topper and can't quite stretch their budget.
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 adding any other bedding.
You should also ensure the firm mattress topper is the right side up, particularly a mattress topper with different layers. 👀
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 LinkDream topper includes a 100-night trial and a 10-year guarantee:
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.
