Casper vs. Purple – Our 2021 Mattress Comparison

Written by Brad Nehring

The Bottom Line.

  • 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.

  • People who experience frequent neck, shoulder, or back pain.
  • Couples who awaken easily due to movement or noise.
The Purple Mattress Is Good for...
  • Side and back sleepers who weigh 130 pounds or more.
  • Hot sleepers, particularly those who find all-foam beds too warm.
  • Those who prefer firmer sleep surfaces that offer moderate conforming.

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.

Our Recommendations

Choose the Casper if...

  • You experience frequent aches and pains, particularly in your neck, shoulders, or lower back.
  • 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.

Choose the Purple Mattress if...

  • You tend to sleep hot, since the buckling-column gel layer promotes air circulation and the mattress sleeps fairly cool as a result.
  • You weigh at least 130 pounds.
  • 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.

How Is the Casper Built?

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.
