The Casper is the superior choice if you’re looking for a softer, higher-conforming mattress.
The Lull is suited to fans of all-foam mattresses looking for a firmer option.
Both mattresses absorb motion and produce minimal noise.
Casper vs. Lull Mattress Overview
Casper vs. Lull Mattress Overview
Casper was founded 2014. Casper’s flagship mattress, the Casper, is made with comfort layers of polyfoam and memory foam, along with a support core constructed from high-density polyfoam and a polyester cover. This bed is considered ‘Medium,’ or a 5.5 on the 1-10 firmness scale.
Lull first launched in 2015. The brand’s flagship bed, known as the Lull Mattress, is a mixed-foam model featuring comfort layers of gel memory foam and transitional polyfoam, as well as a high-density polyfoam support core. This mattress is considered ‘Medium Firm’ (6.5).
Please note: Casper offers two other mattresses in addition to their flagship model: the Casper Essential, a memory foam mattress; and the Casper Wave, a memory foam and latex mattress. This comparison page will exclusively compare the Casper and Lull Mattress. For more information about other Casper models, please visit our Casper Mattress Reviews page.
The Casper and Lull Mattress share some similarities regarding construction and performance, but they also differ in terms of firmness, pricing, and other factors. This page compares the unique pros and cons of both beds, as well as the individual policies and overall reputations of their manufacturers.
Specifies how long the product maintains structure, providing comfort and support before it begins to deteriorate. For reference, the average mattress lifespan is 6-8 years.
The Casper is built with a strong support system that gives it a longer-than-average expected lifespan of about seven years, though some body impressions may form over time.

Off-gassing
x
Most new products emit chemical smells after being removed from packaging. Off-gassing odors are considered non-toxic, but can be quite unpleasant nonetheless.
The Casper may emit moderate off-gassing when new, but persistent odors should not be a major issue.

Pressure Relief

This refers to the degree to which a mattress molds to or cradles the contours of the body. This helps alleviate pressure point pain, especially on the hips and shoulders.
The Casper offers comfortable conforming and targeted pressure relief for most sleepers, particularly lighter side and back sleepers.

Temperature Neutrality
x
The temperature of a mattress throughout the night is affected by how much body heat is retained. Several factors affect temperature neutrality, including material composition, layer thickness, and dissipation of heat through airflow.
Casper mattresses absorb minimal body heat and sleep fairly cool compared to other memory foam mattresses.

Edge Support
x
The degree to which the perimeter of the mattress supports body weight. In some cases, mattresses may sink when weight is applied. This sinkage, often called “roll-off”, affects how closely you might sleep to the edge of the bed.
The Casper offers good edge support due to its thicker support core, but some sinkage around the perimeter is likely over time.

Noise

Certain mattresses – particularly those with coils – can be quite noisy when bearing weight. Others are nearly silent. Material composition is often the limiting factor for noise potential.
Casper mattresses are virtually silent when bearing weight.

Sex
x
Mattresses that are bouncier and more responsive tend to be better for sex, as they’re easier to change positions on. In contrast, unresponsive mattresses can cause couples to have trouble switching positions.
Our testing indicates that The Casper isn't particularly responsive or bouncy, given it's construction. This may make is insufficiently bouncy for some couples, but this is on par with other mixed-foam beds.

Sleep Position Ratings
The Casper Mattress
The Casper’s ‘Medium’ (5.5) firmness and average profile make the mattress most suitable for sleepers who weigh 230 pounds or less; heavier individuals may find the mattress is too soft. The Casper also isolates motion transfer exceptionally well and produces no noise when bearing weight, making it a good option for couples who experience sleep disturbances due to noise or movement.
The Lull Mattress
The Lull Mattress has a ‘Medium Firm’ (6.5) feel that is optimal for sleepers who are considered average weight (130 to 230 pounds) or heavier than average (more than 230 pounds). It may be too firm for those weighing less than 130 pounds, or those who like mattresses that hug the body closely. The Lull Mattress also isolates motion fairly well and does not make any noise when bearing weight.

How Is the Casper Built?
The Casper features a mixed-foam comfort system with top and bottom polyfoam layers and a middle memory foam layer. These materials create a ‘Medium’ feel that offers close body conforming. A high-density polyfoam support core reinforces the bed and helps maintain an even, sag-free sleep surface.
At 12 inches thick, the Casper’s profile is considered average. It is also much lighter than the average all-foam bed (71 pounds in a queen size), making it easy to lift and rotate for most owners.
How Is the Lull Mattress Built?
The Lull Mattress has a 3-inch comfort system with a top layer of gel memory foam and a second layer of transitional polyfoam. These layers create a ‘Medium Firm’ feel that provides some conforming, but not as much as the Casper and most other all-foam beds. It also contains a 7-inch high-density foam base that provides great sleeper support.
The mattress measures 10 inches thick, which is on par with the average bed profile. Like the Casper, the Lull Mattress is relatively light (74 pounds in a queen size) and easy to lift and rotate as recommended.
