Casper and Lull are both relatively young start-ups that have risen to the top of the mattress industry in a short amount of time. In the five years since its launch, Casper has consistently been at the forefront of the push towards online retail, setting the standard for the brands that have followed. Meanwhile, although it’s less of a household name, Lull has become a strong disruptor in its own right by taking a different approach than most of its competitors.
Specializing in all-foam and hybrid mattresses, Casper offers three models: the Casper, the Essential, and the Wave. Lull, on the other hand, offers only one: the memory foam Lull Mattress. In this guide, we’ll just be comparing Lull’s signature mattress with Casper’s flagship model, the Casper.
To help you pick the foam mattress that best suits your needs, we’ll go over the essential details of both mattresses, as well as the important things to look out for when making your final decision.
Mattress Construction Comparison
Casper’s flagship mattress is made out of four layers of foam: The 5-inch core layer on the bottom is made out of poly support foam, which is the standard material used for a support layer in memory foam mattresses. Then comes a 1.5-inch transition layer made out of foam with zoned support, meaning it’s softer around the shoulders and firmer near the hips. A high-density 1.5-inch memory foam, for pressure relief, contouring, and responsiveness, sits on top of the transitional layer. Finally, topping the mattress is a 1.5-inch comfort layer made out of breathable, open-cell foam that keeps out heat.
For an additional fee, you can also add on hybrid technology, a layer of inner springs that gives the Casper more lift, edge support, and better cooling properties.
The Lull’s flagship mattress is made out of three layers of foam. Its 7-inch core layer of poly support foam makes it especially firm, durable, and supportive. Its 1.5-inch transition layer, made out of a blended foam, provides additional support and superior motion isolation. Topping both of these is a 1.5-inch comfort layer made out of a gel-infused memory foam that provides cooling properties, as well as pressure-point relief, comfort, and responsiveness. All three work together to prevent the sag and sinkage you’ll find in traditional memory foam mattresses.
The most important factor when it comes to buying a mattress is firmness. This determines how stiff or yielding a mattress is, which directly impacts how comfortable you’ll be. Some people prefer firmer mattresses, while others prefer softer ones, and these softness/firmness ratings may feel unique to everyone. Other factors, like your weight and sleeping position, will affect the firmness of the mattress you’ll need. For example, heavier sleepers tend to require medium-firm to firm mattresses to receive adequate support and comfort. In this guide, we’ve assigned a rating on a scale of 1 to 10, with 1 being extremely soft and 10 being extremely firm, to Casper and Lull’s mattresses.
The Casper’s top three layers, made of types of foam aimed at providing maximum comfort, contour, and softness, earn it a 4 in firmness. The Lull, with its 7 inches of supportive poly foam, lands at a 6. This puts both mattresses in the “medium firm” category, a common firmness level assigned to mattresses that offer some plushness but not as much sinkage It is a solid choice for all types of sleeping positions and sexual activity, as well as sleepers who weigh between 130 pounds and 230 pounds. That said, the Lull is the noticeably firmer choice, and we rank it as uniquely firm for a memory foam mattress.
Firmness is just one of many elements you should take into account when shopping for a mattress. Temperature control, motion transfer, responsiveness, resilience and bounce, edge support, and off-gassing all impact the sleep experience you have, so you should research all of these important pieces of information before making a decision.
Keeping your mattress cool and comfortable throughout the night is essential for a good night’s sleep, especially if you’re sensitive to heat, or if you get night sweats. It isn’t simply a matter of comfort–warmth interferes with your sleep-wake cycles. Therefore, it’s essential that you find a mattress that doesn’t cut off airflow around your body or retain heat. This depends on the mattress’ material, density, and contouring ability.
While foam mattresses are notorious for trapping heat and preventing airflow, Casper and Lull both have fixes in place to try and combat this. The Casper’s open-cell foam top layer keeps it from retaining heat and its bounciness keeps the sleeper from sinking in too far and blocking airflow. Meanwhile, the Lull’s top layer is infused with a cooling gel. We recommend the Casper over Lull for those who tend to sleep especially hot.
Motion transfer is an important deciding factor for those who share a bed because it dictates how much you can feel the movement of your bedmate. Therefore, you’ll want to pick a mattress that has quality motion isolation.
The Casper has less motion isolation than most traditional memory foam mattresses, because of its bounce and responsiveness. The Lull’s thick foam layers provide superior motion isolation. We recommend the Lull over the Casper if you’re a light sleeper who is easily disturbed.
Responsiveness applies to how responsive a mattress is to the weight of different parts of your body. This is essential to keeping your spine aligned and properly supported.
Working with zoned support levels (softer in the shoulder and firmer near the hips), the Casper’s comfort layers of memory and open-cell foam provide targeted contouring and pressure relief to different parts of your body. Meanwhile, the Lull’s three layers of foam are a little firmer than traditional memory foam, lacking its signature “hugging” contour. Therefore, we recommend the Casper over the Lull if responsiveness is important to you.
Resilience and Bounce
When it comes to mattresses, resilience refers to how easily a mattress will bounce back to its original shape. This is an important factor because it can contribute to how easy it is to change your sleep position or have sex.
While traditional memory foam mattresses tend to have less resilience and bounce than other types, both the Casper and the Lull are designed to take this on. One of the Casper’s selling points is its unique bounce and responsiveness, partly due to its open-cell foam. The Lull is noticeably firmer and less “hugging” than most memory foam mattresses. We would rate them both as excellent choices for a resilient, bouncy mattress.
As you might imagine, edge support refers to how well the edges of the mattress support your weight when you sit or sleep there. TMemory foam mattresses typically provide less edge support than mattresses made from other materials, and both the Casper and the Lull are no exceptions. If you go for either of these mattresses, you’ll have to keep in mind that you’ll experience some sinkage when moving to their respective edges. A more traditional innerspring or hybrid bed may be a better option if you’re especially concerned with edge support.
Off-gassing and Smell
Off-gassing is the temporary smell that comes from a mattress after you take off the packaging, so will only be a problem when you first receive it. That said, if you’re trying to use your mattress immediately, and don’t have a few days to air it out, this can be an annoying obstacle. Because the Casper’s off-gassing goes away after a few hours, while the Lull’s sticks around for a day or two, we’d recommend the Casper over the Lull when it comes to smell.
Shipping, Trial, Warranty, and Returns
While the physical aspects of a mattress are the most important when it comes to making a choice, you might also want to consider shipping, sleep trials, warranties, and return policies. These impact how quickly or easily you can get from ordering a mattress to having it set up and ready to go. They also dictate whether you can try out several mattresses before making a final choice, as well as whether you can replace your mattress if anything happens to it.

Prices, Sizes, and Value
When shopping for a mattress, you definitely want to take price into account. Whether you can stay within the budget you’ve set, get a mattress that’s worth its price, and buy a larger mattress at a discounted price-tag, are all some factors that might impact your final decision.
Whether the Casper or the Lull is more expensive depends on what size you get. The Casper starts off being more affordable than the Lull when it comes to Twin and Twin XL mattresses but ends up being almost $300 more expensive than the Lull when we reach the King and California King sizes. This difference gets even bigger if you want to add hybrid technology (inner springs, cooling, and more edge support) to your Casper, with this luxury addition tacking on $200 to your total bill.
Whether this higher price tag is justifiable is entirely up to what you’re looking for in a mattress. Since the Casper and the Lull offer two different sleeping experiences. Opting for a Lull when you don’t like firmer mattresses just because it’s cheaper, or splurging on the Casper when you actually need heavy motion isolation, doesn’t necessarily make sense.
Casper Mattress vs. Lull Mattress – Which One Should You Buy?
Even with all of these factors laid out, it might still be hard to choose between the two great options. Therefore, we’ve laid out some guidelines so that you can better decide on the mattress that best suits you and your specific preferences.
Buy the Casper mattress if you:
- Want a mattress that stays cooler: The Casper’s open-cell foam comfort layer and increased bounce makes it a cooler choice than the Lull, whose gel-infused top layer may still be an issue for people who sleep hot.
- Want a more responsive mattress: he Casper’s targeted pressure relief and zoned support make it a more responsive choice than the Lull, which offers less contouring and more firmness throughout than a traditional memory foam mattress.
- Care about brand recognition: Casper is the more well-known (as well as more expensive) of the two companies, so if a name-brand matters to you, you might want to opt for the Casper.
Buy the Lull mattress if you:
- Want superior motion isolation: The Lull’s thick foam layers give it superior motion isolation qualities to the Casper, which isolates motion less than traditional memory foam mattresses due to its bounce and responsiveness.
- Want a firmer mattress: At a 6 in firmness, the Lull is a noticeably firmer mattress than the plusher Casper, which ranks at a 4. So if you’re looking for more overall support and less sinkage, you’ll want to go with the Lull.
- Want foam that “hugs” you less than traditional memory foam: Due to its firmness, the Lull will “hug” you less than the Casper, which is hyper-responsive when it comes to contouring.
Both the Casper and the Lull are excellent medium-firm foam mattresses that are superior in many ways to traditional memory foam mattresses and offer similar delivery, trial, warranty, and return policies. Which one you decide to go with depends entirely on if you prefer a responsive, plush foam mattress that sleeps cool, maintains its bounce, and has a highly recognizable brand name (Casper), or an affordable, supportive foam mattress whose exceptional firmness and motion isolation set it apart from other mattresses in this material (Lull).
Because both companies offer a 100-night-long trial, you can test them both out before determining which mattress best suits your needs. Ultimately, though, if you’re simply looking for a high-quality mattress that provides all the comfort of a memory foam mattress with few of the downsides, then either one of Casper and Lull’s flagship models would make a solid choice.
