What Is a Mattress Topper?

A mattress topper is an individual layer of cushioning that rests on top of the bed’s sleep surface. It provides additional support for mattresses that sag, as well as extra softness for mattresses that are overly firm.

Mattress toppers are popular with people suffering from back pain and sleeplessness. They use it to alleviate discomfort, pressure points, and aches that can occur night after night. Manufacturers make mattress toppers from a variety of materials. However, those made from latex or memory foam are considered the best for pressure relief and back pain. Mattress toppers vary depending on the mode, brand, high-quality foam and latex.

Causes and Symptoms of Back Pain for Sleepers

According to the Mayo Clinic, the following conditions are commons sources of back pains and restlessness in adults.


Arthritis is a joint inflammation that occurs anywhere in the body. When it occurs in the spine, it may cause the spinal column to become narrower. This can lead to a painful condition known as spinal stenosis.

Ruptured disc

Pads, known as discs, cushion our vertebrae. They are vulnerable to rupturing when pressed against the nerves in your lower back. The result is shooting pain along the spine.


Scoliosis is a skeletal irregularity that causes the spine to be S- or C- shaped. People that suffer from this condition experience some level of back pain.

Ligament and muscle strain

This can be caused by strenuous activity, awkward movements, lifting or sudden movements. This can cause some strain to your spinal ligaments or back muscles.


This condition causes pores to form in your bones. In effect, they will become brittle, deteriorating quickly. When this happens in the spinal column, it causes severe back pain.

Important Considerations Before Buying a Mattress Topper

Linenspa 2 Inch Memory Foam Mattress Topper, Gel Infused King Mattress...

In case you’re in the market for a new king mattress topper for your king bed, here are a few factors to consider before purchase.

Memory foam or latex?

Memory foam conforms more closely to your body’s shape than latex toppers. Sleepers are likely to experience more pressure and pain relief. However, foams may emit unpleasant gassing and sleep hotter than latex toppers. It’s also important to know that memory foam has a short lifespan. Latex toppers are more durable and cooler.

What is your budget?

A king mattress topper for a king-sized bed is on the high price range. Latex mattress toppers cost anywhere between low and average price range. Depending on your budget, you can decide on which mattress topper to buy that best serves your needs.

What is the density of the mattress topper?

This is a crucial consideration, as most mattress toppers will include ILD (Indentation Load Deflection) or density. The term ILD is used for latex while “density” is associated with foam. Some models have both ILD and density measurements. It’s important to note that the ILD and density cannot be used to determine the mattress topper firmness.

What is your weight?

If you weigh less than 130 pounds, softer toppers with lower ILD or density measurements are preferable. They allow you to sink deeply conforming closely to your sleep surface. However, if you weigh more than 230 pounds, a firmer, high-density king mattress topper size will be more comfortable.

Which topper thickness do you prefer?

People who suffer from back pains find king mattress toppers measuring two or three inches more comfortable. Depending on the model, brand, and material toppers may range from one to six inches.

What is the size of your mattress?

In case you sleep alone, the mattress topper needs to cover the entire length and width of the surface. Your topper size will correspond with your mattress size. For example, a king size bed will need a king mattress topper.

Do you sleep hot?

Memory foam will absorb more heat than latex. Gel-infused foams often feel cooler compared to standard foams. However, a cooling mattress topper with materials such as gel memory foam won’t be as warm for most sleepers.

What is the warranty?

The warranty on a king mattress topper will cover defects in your product for two to five years. It’s important to note that some toppers will not come with any warranties.

Choosing the Right Topper

ZINUS 4 Inch Swirl Gel Cooling Memory Foam Mattress Topper / Cooling,...

Mattress protectors and pads primarily protect your mattress from stains and spills, offering minimal cushioning. Toppers, on the other hand, are designed to offer extra comfort and support for mattress surfaces. When choosing a king mattress topper, you should consider the following attributes.

Composition and durability

Just like your mattress, your mattress topper will begin to sag as the materials wear out. This will cause the topper surface to become uneven making the experience uncomfortable for any sleeper. Different materials are used to make your mattress toppers, meaning different toppers will be suitable for different purposes.For example, fiber has poor durability, poor to fair conforming and fair to good for pain and pressure relief. Memory foam, on the other hand, is good for durability, good to excellent for conforming and excellent for pressure and pain relief. Understanding these variables will help you pick out the best king mattress topper for your needs.

Firmness, density, thickness, and comfort

Mattress toppers are designed to make your mattress feel softer. However, having too much softness is problematic for heavier people. You tend to sink in too deeply. Your mattress surface will eventually be uneven which may lead to back pain and uncomfortable sleep. An excessively firm mattress topper can cause stiffness and discomfort for lighter people. While individual preferences vary from one sleeper to the next, most individuals (120 to 230 pounds) find the medium firm topper as the right balance. Higher density foams will be firm while low-density foams will be excessively soft.Average weight sleepers find medium density foams of 3 to 5 PCF to be beneficial. Heavier sleepers prefer 4 to 6 PCF while light sleepers will prefer 2 to 3 PCF. Toppers measure anywhere from one to six inches, but this does not mean they are better. Thick toppers are soft and sink deep while thin toppers are firmer.


The size of your king mattress topper will depend on the size of your king mattress. If you don’t share your bed, your topper size needs to match the mattress. If you sleep with a partner, you can choose a topper that covers your side of the bed. This is particularly beneficial for couples who have different firmness preferences.
