Casper Mattress Topper Firmness And Feel

Each sleeper has their own unique preferences, which is why we always pay close attention to a mattress topper’s firmness and feel. This way, we can help you make the best purchase for your sleep needs!

What’s The Casper Mattress Topper Firmness?

The Casper mattress topper should soften your existing mattress by two points. On our firmness scale, 6.5/10 is considered medium-firm. If you’re currently sleeping on a firm mattress and need some additional pressure relief, this topper could provide a quick and easy fix.

What Does The Casper Mattress Topper Feel Like?

When lying down on the Casper mattress topper, most people will sink into the foam layers slightly. This creates excellent pressure relief along shoulders and nice body contouring around the lower back. However, because most people will sink into the foam, it can be a bit difficult to move around on top of it.

Sleeping On The Casper Mattress Topper

Overall, the Casper mattress topper is a great pick for back and side sleepers. Stomach sleepers will probably think this topper makes their current mattress feel too soft.

Casper mattress topper - back sleeping

Of course, comfortability greatly depends on each individual’s height and weight. Let’s take a closer look at how the Casper mattress topper will work for different people.

Average Weight Sleepers – 130lbs – 230lbs

Average weight back sleepers should feel some nice body contouring, especially around the hips. Because it has three layers of comfort, the Casper topper is a great pick for average weight back sleepers. It lets you sink in without bottoming out and offers good lumbar support.

It’s also a nice choice for average weight side sleepers. In this sleeping position, average weight people should feel their shoulders gently sinking into the top foam layer, which creates relief for pressure points.

The Casper mattress topper will soften a mattress, so it’s not a good pick for average weight stomach sleepers. For this sleeping position, people should look for a firm mattress that will help the spine stay in alignment throughout the night. For more information, look at our list of the best mattresses for stomach sleepers.

Heavyweight Sleepers – Over 230lbs

While back sleeping, heavyweight people should feel some nice support under their lower backs. The Casper mattress topper is taller than others on the market, so heavier sleepers shouldn’t sink too deeply into the comfort layers.

Because of its height, the Casper is also a great pick for heavier side sleepers. People in this category will likely sink into the top layer and feel the comfort of the second foam layer underneath. The memory foam base helps prevent people from bottoming out.

Heavier stomach sleepers, though, will find the Casper topper makes their mattress too soft. In this sleeping position, heavier sleepers may need a product that adds firmness such as the Lift By Amerisleep Support topper.

Lightweight Sleepers – Under 130lbs

Lightweight sleepers should feel quite comfortable while back and side sleeping. The three foam layers help cushion pressure points and alleviate back pain.

Some lightweight stomach sleepers may feel comfortable on the Casper topper, but most will find it still makes their bed too soft.

Casper Mattress Topper Construction

Now, we’ll peel back the covers and look inside the Casper mattress topper. Here’s more information about its construction.

The removable cover is made out of a polyester blend material.

Comfort Layers

The Casper has three comfort layers. First, there’s a layer of Alt-Latex foam for added plushness and body contouring. Then, there’s a layer of graphite-infused latex foam for cooling. The top layers rest on a base of memory foam.

Casper Mattress Topper Performance

Let’s check out the Casper mattress topper’s performance. We’ll learn more about its cooling features, durability, and more.

Sleeping Hot or Cold

Casper’s foams have tiny pores throughout, so they promote airflow and breathability. Casper also has a layer of graphite-infused latex foam, which is meant to pull heat away from the body. Unlike traditional memory foam mattress toppers, the Casper shouldn’t trap heat.

Durability

The Casper mattress topper is made with high-quality materials, and it should last longer than many other toppers on the market. Overall, we expect it to last about five years.

Off-Gassing

Like Casper’s bed-in-a-box mattresses, the topper needs 48 hours to off-gas and expand before use. You may notice a slight chemical smell when you first take it out of the box, but it will completely fade after two days.

Fit

The Casper mattress topper doesn’t have straps to help it secure it to the sides of the mattress. To prevent it from sliding around, we recommend placing a Casper mattress protector around it.

Cleaning

The Casper has a removable cover, but it is not machine washable. Users will only be able to spot clean this mattress topper.
To protect against spills, we recommend placing a fitted sheet or mattress pad around the top of it.

Allergens

Because Casper utilizes latex foam, it’s a great pick for those who suffer from allergies. The latex is hypoallergenic and won’t trap allergens the way other foams can.

Topper Complaints

While the majority of Casper mattress topper reviews are positive, we occasionally come across some negative feedback. Some people complain that the topper isn’t great for stomach sleepers. Because the topper utilizes soft foam comfort layers, it will make a mattress feel softer. Stomach sleepers should look for a topper that makes a bed feel firmer.

Some customers complained about the way Casper fits on their mattresses. The topper doesn’t have straps on the corners, so it will need a fitted sheet around it.

How Does The Casper Mattress Topper Compare To Other Toppers?

Before buying a brand new mattress topper, we always recommend shoppers look at several different options. Let’s see how the Casper compares with other popular mattress toppers on the market.

Casper Mattress Topper Vs. Dreamfoam Gel Swirl Mattress Topper

Even though they both contain memory foam, the Casper and Dreamfoam toppers have many differences. The Casper mattress topper is 3″ tall and has three different comfort layers. The middle layer is infused with graphite for extra cooling.

dreamfoam mattress topper construction

The Dreamfoam is a 2″ gel memory foam topper, which is meant to promote temperature regulation. It is just one layer of solid memory foam. The Casper will soften a mattress by two points, and the Dreamfoam topper will make a bed one point softer.

The Casper offers more pressure relief, but it does cost more. The Dreamfoam is a great option for those on a budget, and it’s available on Amazon.

Who Should Get The Casper Mattress Topper?

  • Those who need additional pressure relief
  • People who want to make their mattress much softer
  • Those who are looking for a topper that will last a long time

Who Should Get The Dreamfoam Mattress Topper?

  • Those who only want to soften their mattress a little bit
  • People who are on a budget
  • Lightweight sleepers

Casper Mattress Topper Vs. Lucid Lavender Mattress Topper

The Casper mattress topper should soften a bed by two points, and the Lucid Lavender should make a bed 1.5 points softer. The Casper has a cover made with a polyester blend material, and the Lucid topper doesn’t have a cover.

Lucid Lavender Mattress Topper - Construction

The Lucid topper has a zoned construction, so it should provide the right amount of cushioning across the body. It’s infused with lavender essential oils, which are thought to promote relaxation and restful sleep. The Casper topper has three comfort layers that are designed to provide optimal pressure relief.

The Casper has a graphite-infused layer, which is meant to promote airflow and keep sleepers cool. The Lucid topper has a tendency to trap heat, so it’s not a great pick for those who tend to sleep hot at night. The Lucid Lavender topper isn’t as durable as the Casper topper, but it has a lower price point.

Who Should Get The Casper Mattress Topper?

  • Hot sleepers
  • Those who need additional pressure relief
  • People who want a more durable mattress topper

Who Should Get The Lucid Lavender Topper?

  • People who love the smell of lavender
  • Those who want a budget-friendly option
  • Sleepers who don’t want to soften their mattress too much
