Casper Mattress Reviews

Overview

The Casper mattress is designed with multiple foam layers, including a Zoned Support memory foam layer that provides custom firmness for optimal support. Softer foam under the hips helps prevent excessive sinkage in the lower back, while firmer foam around the shoulders and arms offers targeted pressure relief.

While this design suits many sleepers, it may feel too soft for back sleepers who prefer a firmer surface. Lightweight side sleepers seeking more sinkage for pressure relief may also find the Casper mattress less satisfactory.

Comfort and Support

The Casper mattress provides a medium-firm feel, making it suitable for most sleepers. Its cover is simple and durable, and all foam layers are CertiPUR-US certified, ensuring low VOC emissions and no ozone-depleting chemicals.

• The first layer is a proprietary latex-like foam that cradles the body for pressure relief.
• The memory foam layer contours to the body, amplifying support and comfort.
• The zoned transition design offers firmer support at the hips and softer comfort at the shoulders, promoting healthy spinal alignment.

This medium-firm feel is ideal for side sleepers and combination sleepers. However, side sleepers under 150 pounds may find the mattress too soft, which could lead to excessive sinkage and poor spinal alignment.

Back sleepers generally prefer firmer mattresses, but Casper's zoned support helps address common pressure points.

Durability

Casper has established itself as a leading bed-in-a-box brand, offering quality at accessible prices. In 2026, Casper continues to provide:

• A 100-night risk-free trial
• A warranty for added peace of mind
• Showrooms and Target locations for in-person testing

The Casper Original mattress features:

• 1.5 inches of perforated memory foam for cooling and pressure relief
• 2 inches of zoned support foam with tailored firmness for hips and shoulders
• A sturdy base layer of high-density foam for long-term durability

While suitable for most sleepers, those over 230 pounds may prefer a firmer mattress to avoid excessive sinkage. Like many foam mattresses, the Casper may have a slight odor upon unboxing, but this dissipates with proper ventilation.

Cooling Features

Casper mattresses are made in the USA and use non-allergenic latex and safe fire barriers, avoiding toxic chemical flame retardants.

• Open-cell AirScape foam layers encourage airflow and help prevent heat retention.
• This design also minimizes motion transfer, making it suitable for couples and those with joint or back pain.
• The mattress offers a responsive bounce and a firmer feel than many traditional memory foam options.
• Any off-gassing smell should fade within a few hours if the room is well-ventilated.
• CertiPUR-US certification guarantees the mattress is free from VOCs, formaldehyde, and ozone depleters.

Motion Transfer and Edge Support

Like most bed-in-a-box options, the Casper mattress arrives compressed and requires at least an hour to fully expand. Some initial VOC off-gassing may occur, but this is temporary.

• The mattress provides adequate edge support for foam construction, though not as much as hybrid or innerspring models.
• Motion isolation is a strong point, making the Casper a good choice for couples.

For specific sleep positions:

• Back sleepers over 230 pounds may need a firmer mattress to prevent hip sinkage and maintain spinal alignment.
• Stomach sleepers generally require firmer mattresses to avoid midsection sinkage. The Casper's medium feel may be too soft for some stomach sleepers, though its high-density polyurethane foundation layer adds durability.

Overall Impression

Casper mattresses combine multiple foam layers to create a supportive, stable, and comfortable sleeping surface. The design includes:

• A conforming polyfoam top layer
• A zoned transition layer for targeted support—softer at the head and shoulders, firmer at the hips

This structure helps maintain spinal alignment. However, heavier individuals may find the Casper mattress too soft, as their weight can compress the comfort layers more easily. Firmness is subjective, so experiences may vary.

Couples will appreciate the Casper's edge support, which reduces roll-off when sleeping near the edge. Casper's 100% USA production and use of eco-friendly materials reflect a strong commitment to quality and sustainability in 2026.
