How Thick Should A Mattress Topper Be? A Guide to Get It Right Update 05/2024

Adding a mattress topper to your bed is one of the finest ways to upgrade your bed without spending a lot of money. A mattress pad’s primary function is to provide an additional layer of comfort and support that will allow you to sleep soundly at night. Choosing a pad can be confusing, especially when there are so many different types of toppers to choose from. Thickness is also an important consideration when looking for a pad.

In that case, how much of a mattress topper should you expect to need?

In this article, we’ll examine the various alternatives available to you so that you may make the best selection and select the appropriate thickness for you.

The Importance of Mattress Topper Thickness

The thickness of a mattress topper is critical to its ability to provide comfort. If the mattress is too thin, users will feel the bed frame beneath them. In addition, customers who purchase an innerspring mattress will feel the springs pricking them all over.

The right mattress thickness helps the user have a good night’s sleep. As a result, a mattress topper serves a purpose. It is possible to get a good night’s sleep on even the firmest mattress with the help of a mattress topper.

So, how can the average consumer figure out what thickness of mattress topper is right for them?

Consider the weight of the individual you’re buying a mattress topper for while making your purchase. Too thin a mattress topper will have no effect on obese people. If you’re heavier, a thicker mattress topper may cause you to sink in. Consequently, the user should take their weight into account before purchasing a mattress pad.

Choosing a mattress topper for a specific purpose is something else to keep in mind. Adding a thicker mattress topper to a person’s bed may actually make their back discomfort worse. As with hard bed toppers, thickness and body weight must be considered when selecting one for lower back pain.

Additionally, side sleepers require a mattress that is just the right thickness to allow them to move easily. Someone will be “swallowed” by a mattress topper that’s too thick. Side sleepers need mattresses that are wide enough to be comfortable, but not so thick that they are pinned down.

Mattress Topper Thickness Options

In case you’ve never purchased one before or if it’s been a while, you may be startled to learn that mattress toppers don’t come in one size fits all.

2 inches

The types of sleep that individuals prefer are as diverse as the people themselves. If you prefer a firm mattress but need a little extra body support, consider a 2 inch mattress topper. The typical thickness of a mattress topper is 2 to 4 inches. A 2-inch pad may increase support, but it won’t necessarily be a game-changer. In this scenario, the thicker your topping is, the more noticeable it will be.

3 inches

Goldilocks and the Three Bears is a well-known fairy tale. In this children’s story, the middle type was always just right, and you may find yourself in the same situation when shopping for a mattress topper. If you haven’t decided on a pad thickness yet, a three-inch pad is an excellent choice. In addition, the 3-inch mattress topper is a popular choice among buyers.

4 inches

Of course, 4 inches of mattress pad width is at the other extreme of the scale. For people who desire a noticeable increase in support while they sleep, a 4-inch bed topper is the best option. Side sleepers and persons who tend to be heavier may benefit from mattress toppers that are 4 inches thick since they provide additional pressure point relief, allowing for a more restful night’s sleep.

What Types of Mattress Toppers Are There?

Memory Foam Mattress Toppers

In the United States and around the world, memory foam mattress toppers are extremely popular. There is a wide variety of brands, firmness levels, alternatives, and sizes to choose from.

Most other types of toppers are more expensive than this one. As the mattress airs out, chemicals are released into the air. This is the main risk with memory foam.

Mattresses that are environmentally friendly, non-toxic, and completely safe are becoming more common. It is extremely important to confirm that the mattress has been certified by CertiPUR-US, Greenguard, or OEKO-TEX.

Latex Mattress Toppers

Natural latex mattress toppers are also readily accessible and come in a wide range of possibilities. They’re also great at isolating movement. Comfortable and supportive for all sleepers of all ages, thanks to the breathable material.

There are a number of certifications for latex mattress toppers (CertiPUR, OEKO-TEX or Greenguard) to check for as well.

Wool Mattress Toppers

With a wool mattress topper, your body will remain cool while you sleep. The wool mattress topper will also keep you toasty during the winter.

It’s a long-term solution that’s also good for the environment. Wool is made from living animals, is biodegradable, and has a minimal impact on the environment.

Since this topper is made of hypoallergenic material, it is ideal for those who suffer from allergies or asthma.

Down and Down Alternative Mattress Toppers

Down is one of the most luxurious fabrics you’ll find in a bed. Since it’s naturally insulating, it’s great for summer months when you need a lot of fresh air.

In addition to its long-term usefulness, down is also extremely long-lasting. Consider the environmental impact of your down topper before purchasing it. That’s what a ‘RDS’ label would ensure. This signifies that the birds from which your feathers were sourced were not unduly hurt in the process. Due to the chicken farming sector, most down is collected.

Even if you don’t want to go down, you can always go up instead. Most down replacements are made of synthetic materials like polyester or rayon, although it is possible to find natural down alternatives such as cotton, wool, and silk as well.

What to Consider When Looking for a Thick Bed Topper

You’ve made up your mind to get a new mattress topper now. However, the thickness is only one aspect; there are other others as well.

What is the Best Thickness for a Memory Foam Mattress Topper? - The Sleep Judge

Size of the Mattress

As an extra layer on top of your mattress, your toppers should be perfectly aligned. Queen-sized beds, for example, necessitate the purchase of a mattress topper. The good news here is that mattress toppers come in a variety of sizes, making it easy to find the correct one for your bed.

The Condition of the Mattress

Your mattress should be taken into account while determining the thickness of a topper. If you have a new mattress, a 2-inch mattress topper will be fine. However, if your current mattress is more than a few years old, you may want to consider a 3-4 inch thick mattress topper.

The Foam Density

The mass of an object divided by the volume is how you calculate its density. This is because the density of a box with a lot of objects is higher in comparison to the density of a box with few objects. When it comes to bedding, manufacturers use the weight per cubic foot to estimate foam density. The density of a memory foam topper can tell you how long it will last and how it will affect the way your bed feels.

Who Would Benefit the Most?

Choosing the correct mattress topper isn’t simply for those who sleep on their sides.

People with Health Conditions

Just as important as a balanced diet and regular physical activity are obtaining enough sleep and maintaining a regular sleep schedule. An excellent night’s sleep is critical for those who suffer from certain medical ailments. A mattress topper can help tremendously in this regard. Consider a thick mattress topper if you’re overweight or suffer from back pain while you sleep.

People with Allergies

One of the most common places for dust mites to congregate is in mattresses. It is possible, however, to reduce discomfort by adding a mattress topper. If you have allergies, you should also think about memory foam or latex while making a decision. The best course of action is to speak with your doctor before implementing any natural latex alternatives.

Hot Sleepers

A mattress topper can be an energy-efficient solution to keep you cool while you sleep, and fortunately, there are a number of alternatives specifically intended for that purpose.’ Instead of rushing to turn on the fan or the air conditioner every time you wake up sweaty, save money on your utility bills.

People Who Share the Bed With an Active Sleeper

The person next to you may be a night owl, keeping you and your partner awake all night. A thick bed topper can help alleviate your partner’s insomnia by providing an extra layer of comfort and a higher chance of getting a good night’s sleep.
How To Choose A Mattress Topper


It might be as simple as A-B-C – or in this case, 2-3-4 – to choose a mattress topper thickness (inches). There are several variables to consider while choosing the right mattress topper. Everything from the size of your mattress to your overall health and well-being is at stake. Your topping materials are also important. Is it appropriate to use a latex topper? Or perhaps you’re more of a fan of memory foam? Additionally, it has economical advantages. Mattress toppers are not only environmentally friendly, but they can help extend the lifespan of your mattress. Getting the best one is simply one technique to obtain a better night’s sleep, so don’t worry about it.


Can you DIY a mattress topper with custom thickness?

You can make your own mattress toppers, yes. A ready-made mattress topper, on the other hand, might be more cost-effective. You’ll spend more money and time doing it yourself, and the end result may be less than satisfactory. To ensure your satisfaction, a mattress topper that is mass-produced comes with a money-back guarantee and is made by professionals.
