We can buy literally anything online these days, including quality mattresses at a fraction of the cost you’d pay in a retail store. You’ve probably heard of the Casper mattress. They are one of the leaders in the mattress industry. I recently got a chance to try out the queen-size Casper Original mattress and am excited to explore how more than 30 engineering changes have resulted in a product that did exceptionally well in heat transfer.

Like a number of other mattresses on the market, Casper incorporates measures to provide their customers that unique contour only memory foam can offer along with effective bounce to make it easy to move and get in and out of bed. Keep reading for a breakdown of each layer of the Casper Original to show you how it works.

Why You Should Trust Our Review Of The Casper Mattress

At The Sleep Judge, we bring you comprehensive reviews of mattresses so you can decide which one is right for you. Our staff thoroughly test every mattress we review. We unbox them, sleep on them, jump on them, and see if they live up to what the manufacturers claim. We have personal experience with each mattress, and the Casper Mattress is no exception. Our reviewers log sleep time on each mattress. If the manufacturer says the mattress will do something, or won’t do something, we try it out and give you our honest opinion.

Every mattress we review undergoes the same rigorous process. That way we can compare and contrast them and give you an honest review of what we think. You can learn more about how we evaluate each mattress in our Our Mattress Evaluation Process article.

Key Takeaways on the Casper Mattress

Pros	Cons
Good for hot sleeping. In our experience, it did a good job of making our editors feel cool at night.	❌ Some complaints of inadequate support for heavier people. There are better mattresses for heavier people  that we have reviewed previously.
Surprisingly easy to move considering the memory foam. We had no issues moving the mattress, unlike other heavier models.	❌ Not the right mattress if you like the bounce of innersprings. This is personal preference really.
Good motion isolation. Our experience was that we didn’t feel a sleep partner moving when on this mattress.	❌ No natural components. If you like all-natural items, this mattress is not for you.
Good value for your money

Casper Original Cover and Layer Construction

The Casper Original mattress is 12 inches thick and composed of four different layers. Here’s what they are and how they work.

The Cover

The cover is made of polyester and spandex. These premium-grade synthetics result in a cover that’s not only quite breathable but also thin enough to allow you to engage with the comfort layer. If you don’t weigh much, you may find it difficult to fully appreciate your mattress layers. However, the thin, stretchy, and rather pliable cover doesn’t create much of a barrier to the inside of this product.

It features a simple dotted pattern with grey edges. These neutral colors make it easy to work aesthetically in any setting. Unlike other thin covers I’ve experienced, the Casper Original doesn’t bunch up when you move around, and this is because it’s only a tenth of an inch thick (thin enough for engagement but thick enough to stay in place).

The Layers

Under the cover, the comfort layer starts off with a 1 ½ inches of open-cell comfort foam. This material is proprietary, so we won’t be getting into its composition. However, it works like latex to provide the bounce you need for easy mobility. When this aspect is missing, it can be difficult to change positions or get in and out of bed. This can cause serious problems for those who suffer from bone, joint, and muscle disorders.

The second layer makes up the remainder of the comfort zone of this product. It’s comprised of another 1 ½ inches of responsive memory foam. This layer has a slower response to pressure and offers pressure relief. Its strategic placement beneath the response foam allows it to do this without excessive sinkage. It also aids in breathability since memory foam has a reputation for trapping body heat.

To keep you properly supported, the Casper Original mattress then adds yet another 1 ½ inch layer of adaptive transition foam. It’s a little bit firmer than the first two layers. It works, as the name implies, to transition from comfort to support. Like the top layer, the transition foam also features quick response. I like the way Casper sandwiches the memory foam between two responsive layers that work to prevent sleepers from becoming enveloped.

Finally, we arrive at the last 5 ½ inches of the mattress. It’s made up of durable support foam and acts as the foundation of the mattress, supporting the layers above and providing the Casper Original with its basic shape. This layer also provides durability to the overall structure of the mattress.

You can see in this picture how this layer combination provides my body with contour and support. The heavier areas of my body are allowed to sink naturally into the mattress, but there’s a definite point when the support layers kick in. This layer combination is an excellent solution for those who change positions frequently as the response foam, transition foam, and support base all work to provide the bounce you need to keep you from getting stuck in the memory foam.

Casper Original Performance

Now that we understand the inner-workings of the Casper Original mattress, let’s talk about overall feel for a moment. If you’re used to having memory foam in the top layer, it’s going to feel a little strange (but in a good way!). My body clearly sinks into the entire comfort layer.

The top layer of response foam lacks viscoelasticity and offers more resistance to my body weight, and this makes it more bouncy. However, my body still experiences the contouring qualities of the memory foam. You can see how I sink in noticeably until my body force reaches the Adaptive Transition Foam layer. I felt very well supported.

The Casper Original mattress doesn’t have a weight limit as long as you use the right base. If you carry a lot of weight and are worried about sinking too much into your support layers, Casper recommends the Casper Foundation designed to work well with their different mattress lines. It’s best to use a firm, flat, supportive base such as a platform bed or sturdy wooden slats 3-4 inches apart for longevity.

Firmness and Sinkage

Casper Original comes in one firmness setting, and the indentation load deflections of this product are proprietary. This information should have given us an idea of firmness expectations. However, we can still take a look at sinkage when I stand in the middle of the mattress. On a typical medium firm product, I sink 6 ½ inches standing in the middle. On Casper Original, I sink right at six inches, making this slightly firmer than a standard medium. It’s still pretty close, though.

This firmness level should works well for the average shopper. Those who don’t weigh a whole lot may find they aren’t able to engage with the second layer of memory foam as well. In this case, a memory foam topper could be beneficial. Heavier folks who really need something on the firmer side of the spectrum may want to seek out a product that offers more firmness options or an innerspring unit.

Motion Isolation Capabilities

Sleep partners, pay attention. Even in the most secure of relationships, it’s never pleasant to be woken up in the middle of the night on a mattress that allows you to feel your partner’s every move. All-foam products typically do a pretty good job at keeping motion transfer minimal, especially those containing memory foam. In the case of Casper Original, I first tested it out by having someone move around rather aggressively next to me. Their movement wasn’t very disruptive, and you couldn’t see much movement in my body until they started jumping up and down. Watch our video to see for yourself. You can also watch as I drop a 20-pound medicine ball from eye-level next to a resting one of the same weight. The dropped ball experienced a decent degree of bounce for a foam product, but the other ball stays relatively still. Considering the combination of motion isolation and medium firmness, this could make this an attractive option for those with sleep partners.

Heat Transfer Capabilities

Most mattress companies take measures to help you sleep cool. Overheating while you sleep prevents you from experiencing REM sleep, and this is where the most restorative processes take place. The thin cover is naturally breathable. The open cell structure of the comfort foam allows for good circulation using convection and conduction to navigate heat away from your body, while the memory foam leverages airflow to pull heat out of the top layer.

I was pretty impressed when we took a look at the Casper mattress with our thermal imaging camera. I monitored the cooldown process after I had laid on the product for 30 minutes at a room temperature of 64 degrees Fahrenheit. Average cool down time is right around 10 minutes, and Casper Original cooled off in nine. So, Casper’s efforts to keep their product sleeping cool are pretty effective. If you sleep hot and want a product that balances contour and support, Casper Original’s definitely worthy of your consideration.

Edge Support

Sleep partners rely on the entire sleep surface of the mattress, and this includes the edge. Since products made entirely of foam sometimes struggle in this area, let’s look at how the Casper Original holds up.

Laying on the edge, I enjoyed consistent support. I don’t feel uneven or like I was falling out of bed. This is the case whether I laid on my side or back. Now, we often sit on the edge of the mattress. I know I do every time I fold laundry and we all do when we get out of bed. Even with all my weight concentrated to a smaller area, the mattress still does a pretty good job at keeping me supported.

I sink into the comfort layers, but both support layers kick in to keep me from bottoming out. For an all-foam product, I think Casper Original holds up quite well. If you carry a lot of weight and need something with a strong focus on edge support, I’d recommend looking into a product with a strong innerspring unit. But  for the average person, Casper Original’s edge support is definitely competitive.

Maintenance, Protection, Care and Warranty

Unboxing is pretty easy as it doesn’t weigh a whole lot. However, if you don’t want to deal with it, white glove delivery is available nationwide. Either way, you can expect the very slight off-gassing but will subside after a few hours based on experience. This is because foams are Certi-Pur US certified, meaning they are made without ozone depleters and regulated by the Consumer Product Safety Commission. They are also Greenguard Gold certified, the standard for child and infant safety in sleep products. Casper also offers a 100-night sleep trial along with a 10-Year Limited Warranty.

Our Final Verdict

If you’re a combination sleeper who doesn’t have a favorite sleep position, I think you’ll really enjoy the way the comfort layers work together to help you move around easily to find that perfect spot. The combination of support and pressure relief along with the medium firmness is designed to accommodate a wide range of preference. This makes the mattress a great option for anyone with sleep partners. I’d also highly recommend Casper Original if you struggle with hot sleeping. If you’re particularly fond of the degree of added bounce offered by traditional innerspring mattresses or are looking for something with natural components, this probably isn’t the right mattress for you. However, the average shopper on a budget has a lot to gain with the Casper Original mattress.
