2. Detailed Comparison Of Casper vs Eight:

CASPER

EIGHT SLEEP

U

Top Cover

Casper: The cover features a two-tone shade with the top in white while the sides in grey. Expect the top material to be thin and porous which is great for breathability but also snags easily. The side fabrics can handle rough handling.

Eight Mattress: The top of the mattress is a polyester mattress cover that includes the technology that makes the Eight mattress so unique. The technology cover goes over the mattress’ own white knitted encasement. The final look is modern and sleek.

Foam Layers

Casper 9,5-inches total, uses 4 layers: top layer is 1.5-inch poly foam creating a cool surface, acting like latex. Second layer is 1.5-inch memory foam with support and pressure relief. Third layer is the 1.5-inch support foam and the last bottom is 5-inch foam support and base layer. (This is the new updated Casper layers, as of June 2017)

The Eight Mattress 10-inches total uses 4 layers as well. Although similar materials, the design is makes the difference: The top layer is 2-inch reactive poly foam that bounces like latex but feels like foam. The second layer is a 2-inch contouring memory foam that provides pressure relief; third layer is a 2-inch supportive transition poly foam for weight distribution. The bottom layer is a 4 inch high density support base foam for foundation that is highly breathable.

Firmness

The Casper firmness: Provides medium firmness, a 6.5 out of 10 on the scale.

The Eight Mattress feels just right; it is medium firm (6 out of 10) provides the right comfort and firmness.

Body Support

Casper body support: Good body support with pronounced hug and contour but not to the same extreme as you would feel with memory foam.

Eight body support: Highly supportive, shapes to your body to provide the right support for you.

Motion Transfer

Like Eight, Casper has minimal motion transfer because of the foam construction. You wouldn’t easily feel your partner is moving on the other side of the bed.

Eight motion transfer: Does not easily transfer movement between bedsides – so you don’t feel your partner moving next to you – but it still provides the right amount of bounce.
