How thick should a mattress topper be?
Mattress toppers are available in a range of thicknesses. 🙌
Most mattress toppers start around 4 cm - 5 cm (1.57 - 1.9") deep.
An extra thick mattress topper can measure 7 - 10 cm (3 - 4"), almost double the thickness of a regular topper.
What is the thickest mattress topper?
The thickest mattress topper is around 10 cm (4") in depth.
A 10 cm (4") thick mattress topper can provide even more comfort than a standard mattress topper.
The additional depth moulds around your hips and shoulders and relieves pressure from these areas.
An extra thick mattress topper can even make a firm mattress feel softer. 😍
The Acrali Home mattress topper, made with soft microfibre, is one of the thickest toppers available.

What is a mattress topper?
A mattress topper sits on top of your mattress.
It is designed to improve the feeling of your mattress by adding an extra layer of comfort. ☁️
If your mattress lacks support or feels too firm, a mattress topper can help to enhance the overall feel. 💞
Extra deep mattress toppers come in various materials, including microfibre, wool, duck feather, and memory foam.
But what kind of thickness should you desire? 👇
Do you need a thick mattress topper?
So, what type of person requires a thick mattress topper?
Many people could benefit from a thick mattress topper, but it depends on your weight, sleeping position and firmness preference.
Thick mattress toppers are best for side sleepers
Deep mattress toppers are a perfect choice for side sleepers. ✔️
This is because side sleepers need a mattress that moulds around the hips and shoulders when sleeping in the side position.
The best extra thick mattress topper will contour to the body's shape and relieve pressure in the joints.
A thick memory foam mattress topper gently contours around the body's shape and provides a weightless feeling.
Thick mattress toppers are ideal for lighter people
Lighter-weight people may benefit from a thick mattress topper. 👌
Often, even medium-feel mattresses can feel too firm for lighter people. 🧱
A mattress that is too firm can put pressure on the hips and shoulders and have you waking up with aches and paints.
A deep mattress topper cushions those areas whilst encouraging better spinal support for those who weigh less.
Thick mattress toppers can help those with joint pain
Some people suffer from aches and pains in the hips, pelvic region, elbows, and shoulders.
A mattress that is too firm puts pressure on the joints and spine, which can have you tossing and turning throughout the night. 🙁
However, a thick mattress topper will cushion around these sensitive pressure points.
Those who are elderly, pregnant or suffer from chronic pain [2] could benefit from an extra-thick mattress topper.
Alternatively, those struggling to sleep during pregnancy should consider a body pillow for extra support.
Who is a thick mattress topper not suitable for?
A thick mattress topper (or any mattress topper) isn’t suitable for everyone. 👎
Some may find that a mattress topper makes their bed feel too soft.
If you are on the heavier side, you may experience too much sinking when using a deep mattress topper.
Likewise, stomach sleepers need a firm mattress that lifts their back and helps to keep the spine straight. 📏
A thick mattress topper could create a bend in the spine in this position, resulting in back pain.
If you’re trying to make a soft mattress feel firmer, then a mattress topper isn’t the way to go.
Whilst firm mattress toppers are available, a thick mattress topper typically creates a softer feel.
Instead, consider purchasing a firmer mattress like the DreamCloud Luxury Hybrid or Panda Hybrid Bamboo mattress.
When is it time to buy a new mattress?
It’s important to remember no matter how thick the mattress topper is, there is only so much that it can do.
An extra thick mattress topper can help relieve pressure and provide additional comfort.
However, if your mattress is old and dipping, it might be time to throw in the towel. 🙅
A mattress topper isn’t going to be a cure for indents or mattresses that provide no support.
Instead, consider replacing the mattress altogether.
Buying a mattress doesn’t have to be stressful, and most now come with sleep trials and extended warranties to keep you protected. 🤞
Our best mattress guide has the top UK mattress recommendations.
Can you wash a thick mattress topper?
Some thick mattress toppers are machine-washable or include washable covers. 🧼
This is great for those with allergies who need to keep on top of removing bacteria and dust mites [3]. 🦠
Simply pop your mattress topper into the washing machine with your laundry detergent on the recommended setting.
You should check the product label to see if the mattress topper you buy is washable or has a washable cover.
Can I wash a thick memory foam mattress topper?
Memory foam toppers are not washable. ❌
That’s because water can damage memory foam and void your warranty.
We recommend using a waterproof mattress protector over your mattress topper.
This will protect the material and prevent you from damaging the topper and losing your warranty. ☔

Thick mattress topper sizes
A deep mattress topper comes in standard UK sizes.
This includes:
- Thick mattress topper single: 90 x 190 cm (3’ x 6’3”)
- Thick mattress topper small double: 120 x 190 cm (4' x 6'3")
- Thick double mattress topper: 135 x 190 cm (4’6” x 6’3”)
- King size mattress topper thick: 150 x 200 cm (5’ x 6’6”)
- Thick mattress topper super king size: 180 x 200 cm (6’ x 6’6”)
You should choose a mattress topper to match the size of your current mattress.
For example, you should purchase a thick mattress topper king-size option if you have a king-size mattress.
On the other hand, those with a double mattress should opt for an extra thick mattress topper double size.
Thick mattress topper depths
Mattress toppers also come in a range of depths. ✅
Extra deep mattress toppers are usually 7 - 10 cm (2.7 - 3.9 inches) deep.
Thick mattress topper prices
Thick mattress topper prices vary from budget-friendly to high-end. 💰
IKEA mattress toppers are budget-friendly, but their quality and durability may not always meet expectations. 😟
Cheaper mattress toppers also don’t tend to include sleep trials or warranties that can protect you from wasting your money.
Luxury mattress toppers such as the Tempur topper include the best materials but can cost as much as a brand-new mattress.
Consider mid-range mattress toppers such as the Simba mattress topper if you are looking for a good quality topper that doesn't break the bank.⚖️
We recommend investing in a decent quality product that is within your means.

Is an ultra thick mattress topper out of your price range? 🤔

Should you buy a thick mattress topper?
Whether or not you need a thick mattress topper depends on your needs and lifestyle.
A thick mattress topper is an excellent choice for side sleepers, those with joint pain, or lighter weight sleepers who will experience a good night’s sleep on a thick topper.
But they’re not for everyone.🤔
For many, a regular mattress topper or a brand new mattress might be more appropriate.

Frequently asked questions

How to attach a mattress topper
Most mattress toppers come with 4 corner straps.
To attach your mattress topper, wrap the elasticated straps around each mattress corner.
Ensure you secure your mattress topper before placing it on your mattress protector, sheets, and duvet.
Most mattress topper straps are stretchy enough to fit deep mattresses.
Ensure your mattress topper is the same size as your mattress.
Our size guide:
- Single mattress topper thick: 90 x 190 cm (3’ x 6’3”)
- Small double mattress topper thick: 120 x 190 cm (4' x 6'3")

Thick mattress topper materials
Deep mattress toppers come in a variety of materials that have different benefits.
Thick mattress topper materials include:
- Thick mattress topper memory foam
- Goose feather and down mattress toppers
- Gel memory foam mattress toppers
- Hollowfibre mattress toppers
You should consider your individual needs when choosing the materials.
For example, memory foam mattress toppers are hypoallergenic, making them a great anti-allergy choice.
Memory foam is dense and adapts to the body better than most other materials.
However, they also tend to be much warmer than regular mattress toppers.
Natural mattress toppers with a cotton cover are more breathable.
Yet, they can be expensive, particularly if they have a high thread count.
Alternatively, hollowfibre is much more budget-friendly but made with lower-quality materials.
You should determine the essential requirements for your thick mattress topper and what kind of budget you have in mind.
-
Where can I buy a thick mattress topper?
Extra thick bed toppers are available online and in many brick-and-mortar stores that sell bedding products.
This includes:
- Thick mattress topper Argos
- Thick mattress topper Wilko
- Thick mattress topper Dunelm
- Thick mattress topper Dreams
- Thick mattress topper Bensons for Beds
- Thick mattress topper John Lewis
- Thick mattress topper Amazon
There are also lots of popular UK brands that stock thick mattress toppers.
Look at our article on the best mattress toppers for more info.

How thick should a mattress topper be for side sleepers?
Side sleepers will often highly benefit from an extra thick mattress topper.
When sleeping on your side, the weight of your body puts a lot of pressure on your hip and shoulder. ⬇️
The thicker the mattress topper, the more material there is to contour around these pressure point areas and prevent aches in your joints.
But the thickness you need depends on your weight and body shape.
Those with larger shoulders and hips may require a thicker mattress topper than those with smaller shoulders and hips.
Likewise, lighter people may require a softer topper to sink in the topper more deeply.
But a side sleeper with a soft to medium-firm mattress may not require a mattress topper if they're already getting the right level of support.
If you're unsure, we recommend opting for a thick topper with a sleep trial period. ⌛
-
What thickness is best for a memory foam topper?
Memory foam mattress toppers provide a softer more body-hugging feel than other mattress toppers.
However, the ideal thickness for a memory foam topper varies based on your comfort needs.
For a subtle increase in softness, a topper with a depth of 4 to 5 cm (1.57" to 1.9") should suffice.
On the other hand, side sleepers who need extra cushioning to alleviate discomfort might opt for a thicker topper, 7 cm (2.7") or more, which allows for a deeper sink and additional joint-embracing support.
We've yet to see a memory foam mattress topper 10 cm (3.9") or more in thickness.
The Emma Premium topper is an excellent extra thick mattress topper UK at 9 cm (3.5") deep.
-
Are thick mattress toppers bad for your back?
Some may be concerned that a thick mattress topper is terrible for the back, as a firm mattress is often recommended.
However, this depends on your sleeping position, weight, and pressure sensitivity.
Side and back sleepers usually feel more comfortable on a thick mattress topper as it should mould around the body without creating a dip in the spine.
Yet, stomach sleepers need a firm mattress without additional sinking to help keep the spine and neck aligned.
Lighter-weight sleepers will experience more comfort with the addition of a thick mattress topper.
But heavier-weight sleepers may sink too deeply into a thick topper, creating a hammock effect on the spine.
Luckily, many thick mattress toppers include sleep trials so that you can test them out first.
-
What thickness of mattress topper is best for back pain?
If you're waking up with back pain, it may be a sign that your mattress or pillow is not correctly supporting your spine.
Opt for a thick mattress topper with sufficient padding to mould your body's shape while ensuring your spine and neck remain aligned.
The ideal thickness of your mattress topper should consider factors like your body weight, preferred sleeping position, and support from your existing mattress.
Our article offers guidance on topper thickness based on specific needs.
-
Can you get extra thick mattress protectors?
While mattress toppers are known for their depth-enhancing comfort, a mattress protector thick in design can offer some additional comfort.
These are often called quilted mattress protectors.
Nevertheless, the main goal of a mattress protector is to safeguard the mattress.
Selecting a mattress protector with a waterproof layer is advisable instead of prioritising thickness for superior protection.
