Lull VS Casper: comparison image.

We all know that choosing the right mattress can be challenging. However, this Lull VS Casper comparison review will help you to make a decision. 

Both Casper and Lull are memory foam mattresses, however, they’re unique and come with its perks and quirks. While Lull offers only one mattress design, you should note that Casper has two additional models to their original bed - Casper Essential and Casper Wave. 

In this Casper VS Lull comparison, I’ll discuss each of the most crucial features of both beds, pricing, and, in the end, will help you to decide which product to pick. 

To make it even easier, you can check out all the technical Lull VS Casper characteristics here, and then move further into the details. 

Lull VS Casper: Aspects that You Should Pay Attention to

Even though there are many different aspects to consider, there are a few measures that you wouldn’t want to imagine your mattress without, or, at least, you shouldn’t.

So let me introduce you to Lull VS Casper measurements that I’ll be using to evaluate each of the beds:

  • Durability. It’s quite obvious that mattress durability mostly depends on its structure. Even though both beds are still relatively new (4-5 years in the market), it’s possible to evaluate them based on how good they look like after a few years of usage. What is more, I will check out each of their designs to see whether Casper or Lull serve longer. 
  • Firmness. While we pick a mattress not only based on what it feels like but also considering such aspects as health issues, it’s important to have the ability to pick different levels of support. 
  • Edge support. This measurement is crucial for couples. Some beds create this feeling as if you are falling when laying on the side of your bed. If you know this feeling, then your current bed lacks edge support. 
  • Cooling. No one likes to wake up in the middle of the night all soaked up in a sweat. So, one of the most crucial qualities that every good bed should offer is the ability to maintain neutral temperature throughout the night. 
  • Motion and noise isolation. Getting quality sleep without interruptions is crucial. However, if your mattress not only transfers motion but also produces various sounds when you toss and turn, then it’s pretty clear why you wake up tired. 
  • Suitability for sex. Mattress's bounciness and responsiveness to pressure are the two qualities that can show how good a bed is for sex. We’ll see which one of the two Lull VS Casper is the winner at this point. 
  • Best sleeping position. Not all mattresses are great for combo sleepers that the majority of us are. So, when picking a bed, this is also a crucial aspect to be considered. 

Now that we got each of the most crucial aspects that should be considered when picking a bed based on your needs, let’s move to the actual Lull VS Casper comparison and find out which one of them is better. 

Lull VS Casper: The Comparison

Just as I introduced you to the main factors, I’ll go through each of them one by one to make sure that this Lull mattress VS Casper comparison is not only detailed but also clear to each of you. But before rushing into it, check out the general evaluation of both mattresses:

Table: Lull VS Casper general comparison.

At first, they both might seem similarly good but you'll that there are some major distinctions. 


What’s important to understand is that even though there are so many memory foam mattresses in the market, each of them is unique - manufacturers use different techniques and foam density to create products. 

So, talking about Lull VS Casper, let’s take a look into their structure first. Casper Mattress is designed of four individual layers: 

  • 1.5" Latex Foam
  • 1.5" Memory Foam
  • 1.5" Polyfoam/Polyurethane Foam
  • 5" HD Polyfoam

Lull VS Casper: Casper mattress design.

And here’s how the Lull mattress is designed: 

  • 1.5" Memory Foam
  • 1.5" Polyfoam/Polyurethane Foam
  • 7" Support Layer

So, the main difference between the two Lull VS Casper mattresses is that Casper has an additional latex layer. Since latex is natural rubber, it might be a better alternative for those who are looking for more natural alternatives

All things considered, both beds are designed quite similarly, using durable materials. Now, based on the sleepers’ reviews, there's no visible sagging or deterioration after using the mattresses for at least 3-4 years. 

What is more, it’s crucial to mention the fact that both are completely sure about the quality of their products and offer a 10-year warranty. Needless to say, you can be sure to sleep on your new bed for at least this long. In case any manufacturing flaws appear, the providers promise to change your mattress to the new one.

Therefore, it can be difficult to say which one of the two Lull VS Casper offers a longer lifespan. However, I personally, tend to trust Casper mattress better due to its design that incorporates an additional latex layer.

You probably know already that picking the right mattress firmness is truly important. While lightweight sleepers should pick a bed that’s softer in order to feel the benefits of pressure point relief, heavier individuals should consider mattresses that are firmer and more supportive. This way, they won’t sink too much into the bed and the sagging will be much less noticeable. 

So, let’s compare Lull mattress VS Casper firmness. Both beds come in only one mattress firmness option. Casper is medium - 5.5 out of 10 on the mattress firmness scale, and Lull is medium-firm - 6.5. 

Considering the fact that average weight sleepers tend to pick a bed that’s about 5-6 on the firmness scale, it’s pretty clear that Casper can fit more individuals than Lull bed that can be slightly too firm. 

Lull VS Casper: mattress firmness

However, if considering different sleeping positions, one research revealed[1] that back sleepers, especially those who suffer from aches, find firmer alternatives, such as Lull, way more beneficial. 

On the other hand, since the majority of us like to sleep on the side, we usually need medium options that can hug our shoulders while keeping our spine in a straight position. So, when comparing Lull VS Casper suitability for side sleepers, it’s pretty clear that Lull mattress can be too firm for some of us. 

So, as you can probably guess, I would recommend choosing Casper. Even though both beds offer only one firmness option, Casper is a suitable alternative for more sleepers.

Have you ever wondered which mattresses are approved as the best for sleep?

Edge Support

Not all beds provide enough resistance around the corners. You might experience this issue more often when sleeping with your partner rather than alone. What is more, sitting on your bed could also be not the greatest experience as you might feel trapped. 

The lack of edge support is often associated with memory foam mattresses. Since both Casper VS Lull beds are made of foam, it might be a serious issue. So, let’s find out whatever the case is with these two beds. 

It seems that Casper managed to find a way to deal with this obstacle. Compared to the majority of memory foam mattresses, it will support you pretty well. I believe it has to do with a fact that it uses a latex layer that assists pretty well. 

Lull VS Casper: sleeping on the side of the bed.

Now, Lull didn’t surprise me. Even though it doesn’t trap much heat, it performs averagely. But I doubt that anyone wants and “average” product rather than looking for the best

Therefore, the Lull VS Casper battle for the best edge support wins Casper - it will make you feel safe, even when sleeping on the edge of your bed. 


Mattress’s ability to maintain the neutral body temperature is crucial due to the fact that we sleep way better in the neutral environment rather than a hot and cold one. What is more, when heat exposure was compared to coolness, the results revealed[2] that we sleep better in a cooler environment. 

Now, even though many people claim that memory foam mattresses “hug” us and sleep rather hot, it’s necessary to compare Lull VS Casper to find out which one of them can cool your body better. 

Since Casper has a latex layer, I was hoping that it helps this memory foam mattress to sleep cooler. However, the sleepers’ reviews showed that the bed does trap some heat. So, even though Casper performs averagely, I was expecting better results. 

Lull VS Casper: Casper cooling properties

Lull mattress, on the other hand, surprised me by providing great thermoregulation. Even though it seems like a regular memory foam mattress, the fact that it’s firmer than the average bed makes all the difference - it creates less sinkage than Casper mattress and you will feel like sleeping “on the mattress” rather than “in” it, feeling way cooler. 

So, the Lull mattress VS Casper temperature neutrality competition wins the Lull memory foam mattress.

Motion and Noise Isolation

Sleeping with a partner who keeps dreaming nightmares and moves throughout the night, can be truly disturbing. Most of the couples know that. So, instead of sleeping on the couch, you should get a mattress with minimal motion transfer and great noise isolation. 

Without further ado, it became pretty clear when comparing Casper VS Lull that they’re silent when bearing weight due to the memory foam structure. However, when talking about motion transfer, only Lull performed as expected and transferred very minimal movement. 

Now, Casper did a pretty mediocre job. Due to the latex layer, it’s more responsive to pressure, however, also transfers more movement. 

On the same note, let’s continue further. 

Suitability for Sex

Two main aspects that show how good a mattress is for sex are responsiveness and bounciness. Even though memory foam mattresses tend to lack such qualities, you already know that Casper is quite responsive to pressure. Lull, on the other hand, is not that fast at reacting. 

Lull VS Casper: couple sleep

Sadly, it seems that the lack of bounciness in both beds doesn’t make them the best option for sex. However, if choosing from the two Lull VS Casper, I would go with Casper mattress as it offers better responsiveness that’s not only great for the private time but also allows the mattress to adapt to different sleeping positions quickly. 


Just like every measurement that I provided you before, mattress pricing can also make a difference when deciding which bed to choose.

All things considered, both Lull and Casper are quite great options, however, the results showed that Casper is a better option for average weight sleepers. What is more, it has better responsiveness and edge support that many memory foam mattresses lack. 

Even though Lull offers a few factors that are better than Casper's, it does lack pressure relief that is crucial to every sleeper. I would only recommend Lull bed for heavier individuals and those who prefer sleeping on their back.

Which is better Lull or Casper?

Both mattresses are durable and made of quality materials, however, Casper is a more optimal option as it's medium on the firmness scale, whereas, Lull can be too firm for some. What is more, Lull uses the first memory foam layer that will give you that sinking feeling. Casper, on the other hand, is more responsive to pressure due to the first latex layer.

What is a memory foam mattress?

Memory foam mattresses are created mostly from polyurethane and have additional chemicals added that increase its viscosity and density. It’s also often called “viscoelastic polyurethane foam”. In order to create the air movement and let your body “breath” while you sleep, it has open foam bubbles. Memory foam mattresses are created in a way to adapt to your body curves and to also recover their original shape after you get up. Therefore, this kind of top mattresses offer you the feeling as if is created specifically for you.

Do top rated mattresses offer a money-back guarantee? Is there a catch?

All of the top mattress brands offer a money-back guarantee. The free trial usually starts from 90 to 100 nights, and if you don’t like the mattress, you can simply give it back. The majority of best mattress providers will not only give your money back but will also come to get it for free. If the mattress provider is reputable, there won’t be any catch - everyone understands that you have to try the mattress before knowing if it fits you.

What is off-gassing? Is it poisonous?

Off-gassing refers to the odor which comes from a new mattress. It’s the process that happens when volatile organic chemicals (VOCs) leak out of the mattress foam into the air. Those chemicals include both human-made and natural components, including formaldehyde, chlorofluorocarbons (CFCs), benzene, trichloroethane, and perfluorocarbons. Top rated mattresses will have zero or very minimal off-gassing. Many of them are sent to the customer already after the off-gassing. Is it dangerous, though? Even though the smell can be unpleasant, there’s usually only a very small amount of chemicals that can do no harm to your health.

How long do top rated mattresses serve?

The durability of a mattress depends on the provider and the quality of the materials used. Usually, you get a 10-year warranty, which will be valid in case of any defects. Normally, mattresses will serve you from 7 to 10 years, or even longer. Thus, when you buy the best mattress, you should take it as a long-term investment.
