The Casper is a memory foam mattress that offers a medium feel, close body conforming, and consistent pain and pressure relief.
The Purple Mattress is built with a Smart Grid comfort layer with a medium-firm feel. The bed sleeps cooler and provides more support for heavier individuals.
Both beds isolate motion transfer for couples.
Casper vs. Purple Mattress Overview
Casper vs. Purple Mattress Overview
Casper first launched in 2014. The brand’s flagship mattress, known as the Casper, features a triple-layer memory foam and polyfoam comfort system, along with a high-density foam support core.
Purple was founded in 2015 following a successful Kickstarter campaign. The Purple Mattress, its flagship model, is constructed with a comfort layer of buckling-column gel dispersed throughout an elastic polymer grid. The support core is made of high-density polyfoam.
Please note: Both Casper and Purple sell other beds in addition to their flagship models.
Casper offers two other models: the Casper Essential is a memory foam mattress; and the Casper Wave is a mixed memory foam/latex mattress.
Purple offers the Purple Hybrid and the Purple Hybrid Premier, a hybrid mattress constructed with a buckling-column gel and elastic polymer comfort layer, as well as a pocketed coil support core.
This comparison page will exclusively look at the Casper and the Purple Mattress. For more information about the brand’s other models, please visit our Casper Mattress Reviews and Purple Mattress Reviews pages.
Both the Casper and the Purple Mattress offer body-conforming sleep surfaces that alleviate aches and pains in sleepers and isolate motion transfer fairly well. However, both mattresses have unique characteristics, advantages, and drawbacks. This page will compare the Casper and Purple Mattress in terms of construction, performance, and pricing, as well as the policies and overall reputations of both companies.
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.

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.

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.

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

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
Casper Mattress
As you can see, the Casper – like many mattresses with thick foam comfort layers – is ideal for sleepers with frequent aches and pains. Because it is ‘Medium’ in terms of firmness, people who weigh 230 pounds or less tend to feel the most comfortable; people who are heavier than 230 pounds may find the mattress sinks too deeply. The Casper also isolates motion well and produces no noise, making it a good option for couples.
Purple Mattress
The Purple’s buckling-column gel/grid comfort system mimics the pressure-relieving properties of memory foam and latex. However, the mattress is ‘Medium Firm’ and conforms to a moderate extent. People who weigh at least 130 pounds tend to feel most comfortable on the Purple; those who are lighter – particularly side sleepers – may find the bed feels excessively firm.

You weigh 230 pounds or less.
You sleep on your side, back, stomach, or any combination of the three.
You and/or your sleep partner wake up easily due to movement or noise.

Mattress Construction
Next we’ll look at how the Casper and Purple mattresses are made. The table below lists specs for each bed’s firmness, thickness, materials, and other construction details.
The Casper features a comfort system consisting of three layers: a top layer of polyfoam, a middle layer of memory foam, and a bottom layer of medium-density polyfoam. The mattress is ‘Medium,’ and most sleepers experience close conforming from the three comfort layers. The cover is made of polyester.
The Casper’s support core is constructed from high-density polyfoam. This 5-inch layer reinforces the bed and helps maintain a flat, even sleep surface. The Casper is exceptionally light at 71 pounds in a queen size, making it fairly easy for most owners to move and rotate as needed.
How Is the Purple Built?
The Purple’s comfort system has two components, a top layer of buckling-column gel dispersed through an elastic polymer grid and a bottom layer of high-density polyfoam. The gel layer’s conforming and pressure-relieving abilities are on par with those of most memory foam and latex beds, but the material is more durable and less likely to develop indentations.
The support core of the Purple contains four inches of high-density polyfoam, which is less thick that the base layers in most competing models. Its cover is made from a soft, breathable blend of polyester, viscose and Lycra® spandex.
