What Is a Casper Mattress? A Clear, Simple FAQ Guide

If you’re typing “What Is a Casper Mattress” into a search bar, you’re likely trying to understand what makes this type of mattress different, what it’s made of, and whether it might suit your sleeping style. This FAQ-style guide breaks down the basics in plain language.

What Is a Casper Mattress in Simple Terms?

A Casper mattress is a type of bed-in-a-box mattress designed to be ordered online and delivered compressed to your door. The brand is known for using foam-based constructions (and sometimes foam combined with springs) to create a balance of comfort, pressure relief, and support.

Most options under this name are:

All-foam mattresses: Multiple layers of different foams.
Hybrid mattresses: Foam comfort layers combined with a coil support core.

The exact feel depends on the specific model, but they generally aim for a medium or medium-firm comfort level to appeal to a wide range of sleepers.

What Materials Are Used in a Casper Mattress?

Foam Layers

Many Casper mattresses use several distinct foam layers, each serving a different purpose:

A top comfort layer that feels softer and more cushioning.
A transition layer that helps ease the body into the firmer support below.
A support core that keeps the mattress from sagging and supports body weight.

These foams may include memory-style foams, more responsive foams, or zoned foams designed to feel slightly different under various parts of the body.

Hybrid Construction (Foam + Coils)

Some versions combine foam with pocketed coils. This is called a hybrid design and is often chosen by sleepers who want:

A bit more bounce than pure foam.
Potentially stronger edge support.
A blend of contouring and support.

How Does a Casper Mattress Typically Feel?

While comfort is subjective, people often describe these mattresses as:

Moderately contouring: The foam tends to cradle the body without a deep “stuck” feeling in many models.
Medium to medium-firm: Aiming to support many body types and positions.
Evenly supportive: Some designs use zoned support, which means the mattress feels firmer in some areas (like under the hips) and softer in others (like under the shoulders).

Side, back, and combination sleepers may experience this feel differently, but the general goal is a balanced, all-purpose comfort.

Who Might a Casper Mattress Be Good For?

Choosing a mattress is personal, but people who often consider this style tend to be:

Mixed-position sleepers who change positions at night.
Couples seeking a middle-ground firmness.
Those new to online mattresses who want a widely recognized, general-purpose feel.

It may suit sleepers who want foam comfort but do not want a mattress that feels extremely soft or extremely firm.

What Are Common Questions About “What Is a Casper Mattress”?

Is a Casper Mattress All Foam or Hybrid?

Knowing which type you’re looking at helps you predict the level of bounce, edge support, and responsiveness.

How Is It Delivered?

Most Casper mattresses are:

Compressed and rolled into a box
Designed to expand to full size after being unwrapped
Typically used on platform beds, slatted frames, or foundations that provide a flat, supportive surface

Does It Sleep Hot?

Many foam mattresses aim to address temperature with features like:

Breathable covers
Air channels or perforations in the foam
Special foams that seek to reduce heat buildup

Actual temperature experience can vary by person, bedding, and room environment.
