Lull vs. Casper
Today again, we’ll be comparing two all foam mattresses: Lull vs Casper. Although they look pretty similar, they are very different in terms of construction and feel.
The Lull mattress is a proprietary blend of highest-quality memory foams and polyfoams, while the Casper is an updated version of the old Casper model including Zoned support layer designed to provide support to the areas of the body where it is needed most and a comfortable and sound night’s sleep.
Read our review to see what we think about these mattresses and what are our experiences and pick the one that will best work for your specific needs and sleep preferences. Last updated
Construction and Materials
The Lull is a 10-inch universal comfort type memory foam mattress, designed to appeal to a wide range of sleepers, and it is composed of 3 layers of foam.
- A 1.5″ Top layer – The top layer is made of gel infused memory foam designed to provide cooling and comfort for the sleeper.
- A 1.5″ Middle layer – This layer is made up of conventional memory foam designed to support the body and provide even weight distribution and spinal alignment.
- A 7″ Bottom layer – This layer is made of dense support foam. It serves as the foundation for the mattress and works well with the top layers to provide a supportive sleeping surface.
The Lull has an extremely soft cover made of 90% polyester and 10% rayon. It provides breathability to the mattress and aids in cooling.
Firmness and Support
The Lull is a medium soft mattress coming in around a 5/6 out of 10 on the firmness scale (10 being firmness). But as we always tend to mention, firmness is largely weight dependent, and for me, this mattress was firmer than it was for my boyfriend Andrew. He is 230 lbs, and he compressed the top layers more than I did.
The Lull provides a pretty good support, and its combination of foam layers distributes body weight evenly across the mattress.
It isn’t too firm to cause pressure point pain, or too soft not to provide the support needed to sleep comfortably. It is, therefore, suitable for all sleeping positions.
The Lull mattress is a comfortable one, allowing a cool and comfortable night’s sleep. The foam within its layers offers enough give to mold to your body without causing you to feel enveloped by the mattress.
There is a good amount of bounce coming from the gel-infused memory foam layer which perfectly adapts to changes in sleep position as well.
The softness of the cover combined with the initial soft response from the memory foam layers really places this mattress among the most comfortable ones we have tried out to date.
The layer of gel-infused memory foam and soft breathable cover work together to prevent the build-up of heat and the feeling of stickiness usually present in many memory foam mattresses. They work together to create a cool and comfortable sleep surface and provide you with a restful and quality sleep.
Sinkage and Motion Transfer
As it has been already mentioned, sinkage is largely weight dependent and Andrew, being significantly heavier than me, sunk into the mattress more than I did. However, he did not sink down to the foundation, and I did not experience the feeling of sinking into a hole or rolling towards Andrew.
Edge support with this mattress is solid and prevented us from rolling off the sides.
There was a decent amount of motion transfer with this mattress when Andrew adjusted positions during the night which, again, is to be expected due to our weight disparity.
Smell / Off-Gassing
There was a small degree of smell when we opened and unpacked the Lull mattress, but it was nothing overpowering and dissipated within a few hours. This is to be expected due to its all foam nature and the fact that it is shipped compressed in a box.

Construction and Materials
The Casper mattress is a 10″ all foam mattress made up of 4 layers:
- 1.5″ Top Comfort Layer – This layer is 1.5″ of open cell foam designed to provide cooling and comfort to the mattress.
- 1.5″ Response Layer – This layer is 1.5″ of responsive memory foam which provides bounce and responsiveness.
- 1.5″ Support Layer – This layer is 1.5″ of Zoned Support memory foam, which provides primary support and multi-regional zoned support to the areas of body where it is needed most including back, hips, and shoulders.
- 5.0″ Foundation Layer – This layer is 5″ of durable support foam that acts as the foundation and provides deep compression support.
The cover of the Casper mattress is made of a soft polyester blend. It is thick and snaps back into place quickly and won’t bunch up when you move around at night. It is removable as well so that it can be taken off and cleaned.
The exterior small dimples give the mattress a good feel and aid in breathability and increased airflow through its various layers.
Firmness and Support
Just like the Lull, the Casper comes in one universal firmness option designed to appeal to around 80% of sleepers, and we rate it at a 6.5 out of 10 (10 being the firmest).
Unlike the original Casper we reviewed that incorporated latex in its comfort layers, this one has a more supportive, faster response top comfort layer made of responsive foam.
The underlying comfort and support foam layers provide the body contouring and “sinking in” sensation that memory foam is normally known for, without being too soft and causing us to sink down too much and feel trapped in foam.
This mattress also provides enough support in the comfort layers without making Andrew sink all the way down through them and come to rest on the base and core support layers beneath as this updated version is also much denser and better made.
Just like the Lull, it does a great job of providing body hug and contour without causing you to feel trapped in foam, and it is supportive enough for all sleeping positions. It has enough give in the top comfort layer to support your shoulders and hips and enough firmness if you switch to your stomach and back.
As I have already mentioned, this mattress now includes Zoned Support which provides your body with optimal support in the areas where it is needed most such as your hips, back, and shoulders.
The new Casper mattress is much more comfortable than its predecessor which is largely due to the removal of the latex layer and including highest-quality foam layers.
The open cell foam used in the top comfort layer provides cooling and breathability and makes the mattress feel very comfortable for all types of sleepers.
The layer of responsive foam provides enough bounce and responsiveness needed when switching positions during the night and supporting your weight with ease, especially if you are a heavier sleeper like Andrew (230lbs) without causing too much motion transfer. All this makes this mattress excellent for sex as well.
The Casper has that classic memory foam body contouring and hug feel without causing the “sinking down into a hole” feel that traditional memory foam mattresses often tend to cause.
Although some review sites describe the Casper as being firm, we feel it is of perfect firmness with its responsive memory foam providing necessary bounce and responsiveness while cradling your body and creating that well-known feeling of hug typical for memory foam.
All in all, the new Casper is a comfortable, supportive and cool sleeping mattress that will provide you with a comfortable and sound sleep and the much-needed rest.
Being designed to sleep cool through advanced testing and molecular engineering, the Casper mattress, just like the Lull, does a great job at not sleeping hot. The open-cell foam used in the top comfort and cooling layer helps promote airflow throughout the night and prevent heat retention.
Casper even went so far as to have the thermal resistance tested by a third party lab, Element Materials Technology, and found it outperformed competitors.
As a couple living in Texas, we are very tough when it comes to beds that sleep hot and don’t do what they advertise, but the Casper does exactly what it says – it does not sleep hot at all. The unique design and construction of this mattress prevents the buildup of heat and eliminates sweating during the night and the feeling of stickiness typical for most memory foam mattresses.
Sinkage and Motion Transfer
Although sinkage is largely weight dependent which means that heavier people will experience a larger degree of it than lighter people, the Casper does an excellent job at preventing excessive sinkage and preventing Andrew from bottoming out the mattress and rolling off its edges even though it is only 10″ thick.
Replacing the latex layer with foam did a great job at making the mattress responsive without causing excessive motion transfer, which makes it especially good for couples.
As mentioned, edge support is also great with this mattress, and better than in most all foam 10″ mattresses we have reviewed. The high-density foams used in its construction do a good job at providing even support throughout the mattress, including the edges and preventing us from rolling off them and Andrew from bottoming out the mattress.
Smell / Off-Gassing
The Casper mattress gets high marks in this category for not having too much of a noticeable smell upon opening the box which most memory foam mattresses tend to have due to their construction and their plastic packages. With this mattress, there was markedly less off-gassing and odor which was rather surprising to us given its all foam construction.
