Casper Mattress Topper Review

Find Out What Makes the Casper Mattress Topper Unique

The Mattress Nerd’s Take: The Casper mattress topper is great for hot sleepers who want to give their mattress a softer, more comfortable feel without sacrificing breathability. However, it is one of the pricier toppers out there, so it isn’t the best option for budget-conscious shoppers. Based on the high quality materials and thickness, we believe it’s worth some extra money, but we also recognize that its price point may be out of range for some folks.

Mattress toppers are a great way to make your firm mattress a bit softer or change the general feel of the top of your mattress. For instance, if you have an innerspring mattress but you love the “hugging” sensation of memory foam, you can get a memory foam mattress topper. It won’t change the feel of your mattress completely, but it will give you more of that hugging feeling.

The mattress topper from Casper, one of the most popular bed-in-a-box companies, is a great option for all kinds of sleepers because of its unique materials. The Casper mattress topper provides some of the same pressure relieving qualities as the Original Casper Mattress. It combines latex and foam for a plush feel that still offers support, and it is designed for premium breathability. In this review, we’ll take a look at some of the benefits and drawbacks of this unique mattress topper.

What Makes the Casper Mattress Topper Stand Out?

Pros of the Casper Mattress Topper

Cooling Properties
If your current mattress gets hot throughout the night, then you might need the Casper mattress topper. A mattress topper can’t change the breathability of your mattress, but it can provide a more breathable buffer between you and your hot mattress. The Casper mattress topper is made from a blend of breathable foam and latex and it is punctured with very small holes. This allows for effective airflow and prevents overheating. Many memory foam toppers have the opposite effect, so Casper is a unique product thanks to its cooling properties.

Pressure Relief
Another reason we appreciate the Casper mattress topper is because it is designed for pressure relief. When we sleep, pressure can build up in various pressure points, like the hips, lower back and shoulders. This is especially problematic for side sleepers, and back pain is often the result of sleeping without a mattress designed to relieve pressure. If you’ve noticed back pain or stiffness, you may not need to buy a whole new mattress. The Casper mattress topper has three layers of latex/foam blend and viscoelastic material which absorbs excess pressure to keep it from building up in your joints.

Low Motion Transfer
Foam mattress toppers, even those mixed with latex like the Casper, are great for isolating motion. This is very important for couples where one or both people tend to toss and turn at night. If your restless partner keeps waking you up on your current mattress, it may be time to invest in a mattress topper that prevents motion transfer. The Casper’s latex and foam blend isolates motion by contouring to your body’s shape, even as you move, which helps prevent the movement from reaching the other side of the bed.

Cons of the Casper Mattress Topper

Price Tag
Mattresses are a sizable investment; if you aren’t comfortable on your mattress, you will likely lose sleep and energy. Those who can’t afford a new mattress might find the perfect solution in a mattress topper. Overall, the Casper mattress topper is great for hot sleepers and side sleepers, but it isn’t the best option for people on a tight budget. It comes in six sizes and the price ranges from $195 to $355. If you’re hoping to stay under $200, then the Casper isn’t going to work for you.

Plush Feel
Many people buy mattress toppers specifically because they have a comfy, plush feel that can soften up a firm or medium-firm mattress. But if you don’t like a plush mattress, then this mattress topper is probably not going to be a good fit for you. Many stomach sleepers prefer a firmer mattress because it supports their lower back better, without making them feel stuck in the topper.

Non-Removable Cover
If you are an accident-prone person known for occasionally spilling things on your bed, then the Casper mattress topper may present a challenge for you: the cover is not removable. If there’s a spill, you can spot clean it with a mild detergent and water, but the cover can’t be machine-washed. 

What is the Casper Mattress Topper Made Of?


The top layer of the Casper mattress topper is made from Alt-Latex, which is a blend of both latex and foam that is designed to be soft and plush, contouring to the natural curve of your spine and providing pressure relief.

Graphite Latex

The second layer of the Casper topper is made from Graphite Latex, which is latex infused with graphite to help reduce heat buildup and keep you cool.

Viscoelastic Material

Finally, the base layer is made from a viscoelastic material which is not too firm and great for comfortable support.

Polyester Blend Fabric

The whole topper comes together with the polyester blend cover. It is made with a combination of polyester, rayon, lycra and acrylic latex.

What does the Casper Mattress Topper Feel Like?

When you lie down on the Casper mattress topper, it feels soft, yet buoyant thanks to the latex and foam blend. After sleeping on it for a while, the temperature remains relatively neutral because latex is naturally breathable, and the graphite in the second layer helps keep you extra cool.

Unlike all-foam mattress toppers and mattresses, the blend of latex should keep sleepers from feeling trapped inside the topper. If you are looking for a very plush, sinking memory foam feel, check out our favorite Pillow Top Mattresses.

When it comes to usability, this topper does not have any ties on the corners to keep it from sliding. According to the website, the material on the bottom of the topper keeps it from sliding without needing ties. This is a common concern with mattress toppers, but sleepers should feel confident in the Casper Mattress Topper to stay in place.

Most toppers ship within 1 to 2 days of your order, at which point you can track your package through a UPS tracking number.

Sleep Trial

If you like the sound of the Casper mattress topper but you aren’t sure if you’re going to like it, Casper has you covered. Their mattress topper comes with a 100-night sleep trial where you can try the topper and, if you don’t like it, you can send it back for a full refund. All returns within the sleep trial window are free to ship back, even if you live in one of the areas where the inisial shipping cost isn’t free.

Warranty Coverage

This mattress topper is backed by a 10-year limited warranty. If you believe there is a manufacturing defect in your topper during that time frame, you can file a warranty claim with Casper to receive a repair or replacement.

Casper Mattress Topper FAQs

Do I get the 100-night trial if I purchase my Casper mattress topper from Amazon?

Unfortunately, each retailer has their own return policy, and Amazon does not honor the Casper 100-night sleep trial. If you want to make sure you have time to test it out, we recommend buying the topper directly from Casper.

Is the foam in the Casper mattress topper CertiPUR-US certified?

Yes! All Casper foams are CertiPUR-US certified, meaning they meet rigorous standards for emissions and performance.

Is the Casper mattress topper a pillow-top topper?

No, a pillow-top mattress topper is typically much softer because it’s stuffed with down or down alternative materials. The Casper mattress topper is made from latex and foam, which are soft and comfortable, but will not have the same feel as a pillow top topper.

The Nerd’s Final Take

Overall, the Casper mattress topper is a great addition to any mattress, especially if you’re a hot sleeper or a side sleeper. Unlike toppers made from memory foam, the Casper mattress topper sleeps cool thanks to its latex construction. However, this improved construction comes at a considerably higher price compared to other mattress toppers, making it a poor choice for many budget shoppers. Because of its plush feel, it also might not be great for stomach sleepers who tend to need a firm sleeping surface.
