How Thick Of A Mattress Topper Do I Need

If you’re looking to buy a mattress topper, you might be wondering how thick it should be. It’s hard to generalize, but this manual offers three different thickness options to play with.

A mattress topper’s thickness is an important consideration when shopping for a new mattress topper.

However, many shoppers are unsure of the ideal thickness for a mattress topper.

Would you consider yourself to be one of them?

Don’t fret; this page will help you determine the ideal mattress depth for your situation.

What A Mattress Topper Is

A mattress topper is not the same as a mattress cover, mattress protector, or mattress encasement, and this must be stressed before we continue.

As the name implies, a mattress topper is meant to be placed on top of an existing mattress to offer an extra layer of cushioning and support.

Different materials are used to create it. Nonetheless, they all accomplish the same thing.

They are commonly used on sagging or otherwise worn mattresses.

Also, this can help hide any imperfections in your mattress that you’d prefer to remain concealed.

Moreover, mattress toppers can be easily removed.

If your mattress is feeling saggy or soft, consider investing in a quality topper to provide you the extra support you need.

Mattress thickness is often determined by the type of material used in its construction.

Depending on your requirements, you should select the appropriate thickness.

Now, let us get into more detail down here.

6 benefits of a mattress topper

Using a mattress topper can do a number of things, from increasing your level of comfort to extending the life of your mattress. Keep reading to learn how one can help you get a better night’s rest.

1. It increases the lifespan of your mattress

By relieving some of the weight off your mattress, toppers can extend its life. So that you may get more out of your mattress and continue to enjoy it for longer!

2. It provides extra comfort

Adding a mattress topper can revitalize an old mattress and restore its softness if you find that you no longer get the same level of comfort from it. They are similar to a thin mattress and can be placed on top of your regular one to extend its useful life.

Some mattress toppers are designed to alleviate pain while you sleep. Why not try out the memory foam options? They conform to your body and provide relief where it’s needed.

3. Your mattress will stay clean and fresh

Since dust and filth are kept from penetrating your mattress by using a mattress topper, your mattress will maintain its cleanliness and freshness for a longer period of time. Some of them, especially those filled with hollow fiber, are fully hypoallergenic, so you may sleep soundly without worrying about triggering your allergies.

Some of them feature removable coverings that may be washed in the machine. Keeping them spotless is a breeze thanks to this feature. It’s a lot faster than vacuuming your mattress, too!

4. It can save you money!

When you add a mattress topper, it might be like getting a new mattress. You won’t have to replace your mattress as soon, and it’ll feel like new.

5. It can change the feel of your mattress

If your mattress is on the firm side, you may want to consider purchasing a mattress topper to help soften the surface. After a long day, this can provide a welcome cushion.

The same holds true if you’re a light sleeper who needs a firmer mattress. A mattress topper with increased firmness will give you the additional support you need.

6. They’re versatile!

Mattress toppers, in contrast to mattresses, can be easily removed and replaced. Even if you find that it makes you too hot in the spring or early summer, you can always store it away and wear it again when the temperature drops. How you employ one is entirely up to you.

How Thick Of A Mattress Topper Do You Need?

There is a wide range of thicknesses available for mattress toppers, from two to four inches.

In addition, a few would extend to around a six-inch depth.

In addition to variations in overall thickness, mattress toppers can also be found in a range of foam densities.

However, the available sizes and thicknesses will be the main points of this post.

Keep in mind that the density and thickness of a mattress topper are crucial factors to think about before making a purchase.

Mattress toppers are often sold in three different thicknesses: two inches, three inches, and four inches.

On the other hand, you might try searching for those one-of-a-kind six-inch toppers if you’d prefer.

Can you recommend a thickness for a mattress pad?

Here’s a quick rundown of the several options for mattress topper thickness:

Thickness #1. Two-inch thick mattress topper

If you’re looking for the thinnest mattress topper, you should know that the thinnest one available is two inches thick.

A mattress with that much thickness can be extremely plush and relaxing.

Additionally, it can provide an additional layer of opulence and softness.

If you’ve just bought a new mattress, and only if you’ve just bought a new mattress, you should get a two-inch mattress topper.

A mattress topper can be used to soften a mattress that is too firm when first purchased.

You shouldn’t use a heavy mattress topper on an old, thin mattress.

For the simple reason that it cannot provide the necessary assistance.

That’s about all it can do, and it won’t prevent flaws like sagging from showing.

Thickness #2. Three-inch thick mattress topper

Although it may seem inconsequential, an extra inch can make a substantial impact.

A three-inch topper is significantly more substantial than a standard mattress, depending on the material you select.

The extra thickness can be beneficial for both support and comfort, regardless of whether you choose a firm or soft topper.

In addition to that, this can make up for the flaws in your current mattress.

The specific mattress topper you go through will determine this, though.

If you already have a latex mattress at home and want to add a memory foam layer on top, you’ll want to get a three-inch thick foam topper.

That mattress you have now is going to get a lot softer and more comfortable.

Or, if you like, you can make it firmer.

Get a topping of your choice, once more.

Thickness #3. Four-inch mattress topper

The maximum thickness for a mattress topper is typically agreed upon as being four inches.

That is because anything thicker than that is not classified as a mattress topper anymore. Instead, it would be a mattress.

That is because anything thicker than that is not classified as a mattress topper anymore. Instead, it would be a mattress.

That’s because federal regulations no longer consider anything thicker than four inches to be a mattress topper. It would be a mattress instead.

A mattress of this thickness can provide a layer that is both supportive and comfortable.

That being the case, you should expect a more restful night’s sleep.

Also, you won’t have any aches or pains when you lie down or wake up.

It would be ideal if one could reap the benefits of a memory foam mattress without having to actually purchase one.

Anyone else think it’s a good idea? The Saatva Mattress Topper has been recommended by numerous sources, including TechRadar, the Sleep Foundation, and Good Housekeeping. 123

The Saatva Mattress Topper is one of the best options for most people after many hours of testing. Our reviewers were impressed by its plush comfort and the firm support it provided. Its weight and density also suggest that it is constructed from high-quality materials meant to last.

Although this topper was rather lumpy and had an awful odor upon first inspection, it was easily smoothed out after being removed from its packaging. While it lacks the softness of certain memory foam mattresses, its excellent support makes it a good choice for people who prefer to sleep in a variety of positions. Our experts gave it a 4.5/5 rating for comfort because they couldn’t feel the weight of an object placed under it. The organic cotton cover and graphite-infused foam make this topper feel significantly cooler than conventional memory foam, which is why our testers scored it 5 out of 5 stars for airflow.

In contrast to its shorter guarantee period, this high-end mattress offers a generous 180-night sleep trial with no restocking fees. The Saatva Graphite Mattress Topper is, in general, a good investment if you want to upgrade your sleep for a higher price.

Runner-Up, Best Overall: Sleep Innovations Dual Layer Memory Foam Mattress Topper

Likes and Favorites

• Design with two layers
• Super soft and cushioned for maximum comfort.
• Designed to remain in place while sleeping
• Assurance for ten years

Our Dislikes

• The top layer has a negligible effect on cooling.

We also found that the Sleep Innovations Gel Memory Foam Mattress Topper was a fan favorite. This one-of-a-kind topper comprises a 2-inch layer of gel memory foam and a 2-inch pillow topper with an attached skirt that functions like a mattress pad. Our panel of experts found that the feel of the two layers greatly improved the topper’s ability to remain in place on the mattress. The topper offered just the right amount of padding without being too thick, and the extra comfort supplied by the top layer made it preferable to plain old memory foam. For comfort, it received a perfect score of five stars from our experts.

This mattress topper has a sticky sensation due to the gel memory foam, but it is simple to set up on a bed and thus earns 4 stars in that category. Thankfully, the foam is concealed by the upper layer. One thing we didn’t like about this mattress topper was that the polyester filling negated the cooling benefits of the gel memory foam. This topping wasn’t the warmest we tried, but after just five minutes of use, its surface temperature had risen by several degrees.

This mattress topper is CertiPUR-US certified, which means that the foam used in its construction satisfies rigorous standards for composition, emissions, and durability. It also comes with a long guarantee of 10 years.

Best Budget: LUCID 3-inch Gel Memory Foam Mattress Topper

Gel memory foam; three-inch height; available in twin, twin XL, full, full XL, queen, king, and California king sizes; CertiPUR-US and retailer-specific return/exchange policies; three-year warranty

Likes and Favorites

• Quite a bargain
• Safe and supportive seating
• Airy feel thanks to ventilation holes

Our Dislikes

• There is a discernable gaseous emission.

The LUCID Memory Foam Mattress Topper is an affordable alternative to high-end memory foam mattresses, offering the same supportive and relaxing sleeping experience for a fraction of the price. Our panel of experts appreciated how breathable and light it was because it was crafted from open-cell gel memory foam (though it did feel slightly tacky to the touch). Its firmer feel than the other alternatives we tried makes this topper a terrific pick for side sleepers or anyone who prefers a more supportive mattress.

Our mattress topper had an odor at initial packaging, so we let it off-gas for the suggested 48 hours before putting it to the test. Our tester mattress fit perfectly. Our sleep testers didn’t report any pain while lying down, despite the fact that we could see bumps when we put objects on top of the topper.

This mattress topper is available in a 2-inch foam layer, which we did not test. The manufacturer backs the product with a three-year guarantee and certification from CertiPUR-US.

Best Foam: Tuft & Needle Mattress Topper

Sizes available in Twin, Twin XL, Full, Queen, King, and California King; Open-cell foam construction; 2-inch height; CertiPUR-US, UL GREENGUARD Gold, and Intertek Clean Air Certification; 100-day trial period and 3-year warranty.

Likes and Favorites

• the perfect thickness
• Useful for those who prefer to sleep on mattresses with some bumps
• Silicone beading maintains the position of the cap.
• Very fashionable outward appearance

Our Dislikes

• A minimum of two individuals are needed for setup.
• Unboxing reveals a powerful odor

The Tuft & Needle Mattress Topper uses an open-cell foam that does not retain heat as much as memory foam, making it a more comfortable option for those who find traditional memory foam to be too hot. The 2 inch thickness was deemed ideal by our panel of experts because it was neither too thick nor too thin. Additionally, we were not able to detect any hard objects placed under the topper, making it a decent option for anyone seeking a solution to a lumpy or unpleasant mattress.

Although the manufacturer doesn’t suggest it, you should probably let this mattress topper air out for a while once you first unpack it because of the strong odor it gives out. We recommend finding a friend to assist you set up the topper, as the cover is equipped with silicone beads to secure it to the bed.

This topper has been certified as low-emitting to help maintain a healthy indoor environment by organizations like CertiPUR-US and UL GREENGUARD. Tuft & Needle has a 3-year warranty and provides a 100-night sleep trial with no hassle returns.

Best Memory Foam: ViscoSoft Active Cooling Memory Foam Mattress Topper

Copper-infused memory foam, 4 inches high; available in twin, twin XL, full, queen, king, and California king sizes; CertiPUR-US and GreenGuard Gold certifications; 60-day trial period; 5-year warranty (when purchased from ViscoSoft)

Likes and Favorites

• A thick and cushiony texture.
• Dissipation of all motion is impossible.
• Comparatively poor heat retention
• All-machine-washable cover

Our Dislikes

• Feeling of slight descent

Because of its softness and buoyancy, memory foam is frequently used as a mattress topper. The ViscoSoft Mattress Topper performed exceptionally well in our tests against other memory foam products. Our sleep testers didn’t report feeling any lumps when we positioned a hard object beneath the topper, attesting to its plush, supporting feel. Since this is the case, it is the best option for those who suffer from a mattress with lumps.

This topper required a 48-hour off-gassing period due to the memory foam material. Because the memory foam requires a cover made of cooling cloth, assembly is also slightly more complicated. While memory foam mattresses tend to get rather hot, this topper kept far cooler than many others we tried thanks to its permeable cover and copper-infused foam. The lack of motion transmission made it an excellent alternative for anyone who is disturbed by their partner’s tossing and turning. It was just a tad too big for the bed.

Both the construction and CertiPUR-US certification of this topper’s materials are made in the USA. Cover may be machine washed for simple upkeep and comes with a 5-year warranty from the manufacturer.

Best Mattress Pad: Nestwell Double Layer Fiberbed Mattress Topper

Cotton and polyester construction; 2″ high; Twin, Twin XL, Full, Queen, King, and California King sizes; STANDARD 100 by OEKO-TEX certification; 90-day money-back guarantee.

Likes and Favorites

• Portable and simple to set up
• Easily maintained
• A plush, pillowy experience is guaranteed.

Our Dislikes

• That’s not a good idea for mattresses that make you feel awkward or uncomfortable.

Toppers are often thicker and more supporting than mattress pads, but they are otherwise very similar. The Nestwell Mattress Topper, for instance, provides a soft, pillow-top effect on top of a hard mattress. Although it is called a mattress topper, our experts said it was more like a mattress pad and didn’t perform like the others they tried.

This one-of-a-kind product is constructed with a polyester fiber-filled gusseted support layer that extends 2 inches from the base and a quilted, snap-fastening cover. Our evaluation team observed that the topper was held in place by elastic bands at each corner, and that objects placed beneath the surface were immediately discernible and felt. This mattress topper’s top layer may be unzipped and washed in the washing machine; after washing, it simply snaps back into place.

Honorable Mention: Nest Bedding Cooling Topper

Certified by CertiPUR-US and available in multiple sizes (including twin, twin XL, full, queen, king, and California king), EnergexTM Foam mattresses have a 2-inch profile and a 30-day trial period.

Likes and Favorites

• Soft and squishy
• Tender and mushy

Our Dislikes

• Definitely not the best deal

While it did not fare as well as some of the other foam toppers we tested, the Nest Bedding Cooling Topper is still one we’d recommend for those who need a little extra softness on a hard mattress. The innovative foam used in its construction was well received by our panel of taste testers. It’s CertiPUR-US certified, created in the USA, and has a sleek design to boot.

This topper was little too short for the mattress and had a faint odor upon opening the packaging. Test objects placed beneath the surface were easily detected, and the material warmed up significantly due to its thinness (less than 2 inches). To make a firm mattress more comfortable, it’s not a terrible solution, although it is more expensive than similar products.

How We Tested the Toppers

The editors of The Spruce spent two days at The Lab putting 11 recommended products through their paces. On a scale from 1 to 5, we ranked the toppers based on their simplicity of assembly, level of comfort, and air circulation. The final list includes eight of the original eleven suggestions.

By timing how long it took to unpack and set up each topper and making mental notes of any odors or faults, we were able to gauge how well they fared in terms of design and convenience of use. The tester’s level of comfort was determined by determining how easily they could feel objects put between the mattress and the topper. Using a surface temperature tester to compare the temperature of the tester’s body to that of the mattress when he or she was not there, we determined the topper’s breathability and ability to retain heat.

What to Look for in a Mattress Topper

Thickness

A thicker mattress topper will offer additional padding and comfort. If you just need a little extra support while sleeping, a thin choice (1 to 2 inches) may be all you need. Conversely, if your bed is exceptionally unpleasant, you may want to invest in a thick mattress pad (up to six inches in some cases).

Material

You can find mattress toppers stuffed with anything from memory foam to down feathers to standard pillow stuffing. There are benefits and drawbacks to each potential course of action: Memory foam mattresses tend to give off an odor when first unwrapped, while down pillows might shed their filling over time. The advantages and disadvantages of each material should be weighed carefully before a final decision is made.

Temperature regulation

How hot are you usually at night? It’s important to keep in mind that different mattress toppers have varying degrees of success in controlling body temperature. In particular, down feathers are far better at maintaining a normal temperature than memory foam, which might lead you to overheat during the night.

Are mattress toppers hot to sleep in?

Most mattress toppers will not make your bed too warm during the night. Since there are numerous options, it stands to reason that some will be warmer than others.

It’s possible that memory foam mattresses will be cozier than their hollow-fibre counterparts at night. But those filled with natural materials, like down or feathers, provide their own insulation. Because of this, you can use them year-round without worrying about overheating. Natural fillings are also highly permeable, allowing for increased ventilation and breathability.

If the memory foam topper you have is excessively warm, you can counteract its effect by using a lesser tog duvet, even though many people like a warmer sensation.

FAQs

How thick should a mattress topper be?

Most mattress toppers are between 2 and 4 inches thick, and the best thickness is determined by individual preference. Mattress toppers constructed from thick, dense foam are your best bet for hiding imperfections in your current bed set. People who just want a bit more cushion on their mattress can get by with a thinner topper.

Are mattress toppers hot to sleep on?

Most mattress toppers are heated because memory foam traps heat. In any case, there are many of temperature-regulating mattress pads on the market. Memory foam with gel or copper infusion is one method of heat dissipation; ventilation holes and cool fabrics are two others. In addition, open-cell foam or latex mattresses are better for hot sleepers because they don’t absorb heat as much.

How long do mattress toppers last?

To a significant extent, the durability of your mattress topper will be determined by the material it is constructed from. Foam of poor quality often degrades after a year or two, while memory foam of higher quality lasts for three to five years. Topping mattresses with latex can extend their lifespan by five years or more.

Can mattress toppers be washed?

Some mattress toppers have removable coverings that can be washed in the washing machine, making them more convenient for frequent cleaning. However, foam toppers can be spot cleaned with baking soda or laundry detergent if they get dirty.

Do mattress toppers help with back pain?

If you suffer from back pain, a mattress topper may be able to assist. This is because they add a firm, even layer to your mattress. Sleeping on a firmer surface may help reduce back pain, according to research.

It’s A Wrap!

One of the main functions of a mattress topper is to improve the comfort, luxury, and support of your mattress.

It’ll be like an extra blanket of support. Also, it can help the bed last longer than it would otherwise.

Again, your individual requirements are the only thing you need to keep in mind when deciding on the thickness.

Some people prefer a softer bed, while others want something harder.

Think about your needs and your desired mattress’s shape before making a final decision on mattress thickness.

The question of “how thick of a mattress topper do I need?” has been discussed to its conclusion.
