What Is a Firm Mattress Topper?

A firm mattress topper is typically denser and thicker than the average pads, thus, it’s less soft and more supportive. Due to the density and thickness of the foam material, it can also be heavier than the standard pads.

The general rule is that the thicker and denser the topper is, the firmer it will be. Thus, a firm mattress topper will likely be two inches in thickness while extra-firm toppers are thicker.

When chosen correctly, a firm topper can provide the following benefits:

• Aids in relieving back pain since the topper makes an existing mattress firmer and, thus, more supportive. You will then have a sleeping surface that will keep your back as straight as possible.
• Adds to the comfortable feeling of an existing mattress. You can place it on top of your older mattress, which likely have sagging areas, for a quick and affordable upgrade. Your sleeping experience will be better for it because the topper evens out, literally, the clumps and sags in your old mattress.

But we must also emphasize that firm mattress toppers have their drawbacks so these aren’t for everybody.  People who sleep on their sides and stomach and those who have joint-related issues (e.g., arthritis) shouldn’t use firm mattress toppers. These people will be better off with a more comfortable – or softer – mattress.

Why you should take a firm topper for mattress? The reason: A firm mattress topper will put more strain and stress on the pressure points and joints. Instead of relieving pain, it can worsen the symptoms, even cause new ones.

Manufacturers use several types of materials in making firm mattress topper, namely:

• Memory foam, a viscoelastic material developed by NASA for its aerospace program, is the most common material used because if its firm surface. The level of firmness, furthermore, will be affected by the density of the memory foam; the density for mattress toppers range from four to five per cubic feet. The higher the number, the firmer the mattress will likely be.
• Latex foam is a material known for its firmer surface than memory foam. This keeps the weight of the user within a localized area while providing a supportive surface, both of which are crucial in keeping the spine in its natural alignment.
• Polyurethane foam is the material used for traditional firm mattress toppers. This doesn’t have a plush feel, as well as suitable for people who have no specialized need for mattress support.

Your choice in the material will be determined by your budget, as well as your need for comfort and support.

What Is an Extra Firm Mattress Topper?

Many people want even firmer mattresses but don’t want to spend hundreds of dollars on a new mattress. This is where an extra-firm mattress topper comes in.

Just like the firm memory pads, it provides its user with a more supportive sleeping surface without sacrificing too much on the comfort. It isn’t as hard as, say, sleeping on a wooden bed or on the floor since it’s still made of one of three of the abovementioned materials. But it definitely isn’t for people who like to sleep on soft mattresses with a plush feel!

The difference between a firm and an extra-firm mattress topper mainly lies in their thickness. The former usually has a thickness of just two inches while the latter can range from three to four inches.

Again, the thicker the topper, the firmer it will likely be although its actual density and type of material will also affect its firmness level.  For example, a 3-inch memory foam topper may be firmer than a 3-inch latex foam topper if it has a higher density.

A 4-inch memory foam topper can be considered an extra-firm topper because it’s thicker than the 2-inch and 3-inch varieties. As such, it’s the best choice for a person weighing 250 pounds and up.

What Is Mattress Topper Firm Support?

Basically, it’s a mattress topper that makes a relatively old mattress firmer and, thus, more supportive. You may want it if your old mattress is already showing signs of wear and tear, such as sagging in the middle, but your budget doesn’t allow it yet.

What Do You Need To Check Before Buying?

A combination with firm topper for soft mattress can make you sleep well. Keep in mind that while firm mattress topper reviews are favorable, the toppers may not address your specific needs and wants in the product. You must then carefully consider whether a mattress topper with firm support is suitable for your lifestyle – and here are the features that must be considered.

The Price

Latex toppers are generally more expensive than memory toppers.

The Thickness and density

Thicker and denser toppers are suitable choices for people who like to sleep on their side, or who are on the heavy side, or who want to upgrade an aging mattress.

The Balance of support and comfort

The main purpose of a firm topper is to provide more support for people who cannot sleep well on softer mattresses, especially for health reasons. If possible, test the topper first in the store before making your decision. If not, ask about the return and exchange policy.

Remember, too, that comfort can also apply to the motion transfer, body heat transference, and allergy potential of the topper. Memory foam and latex foam toppers are popular because these have minimum motion transfer; a partner tossing and turning in his/her sleep will not make for significant sleep disturbance for the other.

But memory foam toppers can become too warm for some people’s liking while latex foam toppers are more likely to stay cool even after eight hours. Memory foam can also cause allergies for susceptible people due to their chemical smell after opening; just air for 72 hours to remove it.

Don’t forget to consider the ease of moving and cleaning the mattress topper, too. You have to consider whether it’s easy to move from and to the bed, as well as its ease of airing and possibly washing of the cover.

Conclusion

We have to emphasize that these firm mattress topper reviews are meant to be basic guides for making a smart choice in said product. In the end, you have to decide for your own which of these ten products will be the best firm mattress topper for mattress you are using.
