About
Who they are.
Casper operates in the sleep products category, producing mattresses, bedding, and sleep-related technology, with an additional line of pet products. Its offerings include the Original Mattress, Contoured Memory Foam Pillow, Glow Light, and Casper Dog Bed, spanning both human and pet sleep environments.
Across its catalog, Casper is associated with cooling and breathable materials, zoned support, pressure relief, and portable or dimmable design elements, reflecting an emphasis on comfort and structural durability. Its pet-focused products extend this approach to dog beds designed to maintain form and withstand repeated washing, addressing the needs of dogs of varying sizes and ages, including those with joint sensitivity.
The verdict
Casper started in 2014, founded in the United States. The company makes mattresses. They shipped the first bed in a box, a compressed mattress rolled tight for delivery. This changed how people bought sleep. Today Casper sells across North America and Europe, a public company known for direct-to-consumer mattress sales. They are tracked weekly among 6649 brands across major AI platforms.

What reviewers say about the brand.
AI summary of 5 reviews · as of Jul 2026
Reviewers see Casper as a pioneering, well-engineered bed-in-a-box brand whose foam and hybrid mattresses balance support and comfort, though its softer beds can feel like a step down for pure side sleepers or those wanting a firmer feel.
What they praise
- Consistent use of solid-density foams and sturdy foam cores across the lineup, aiding durability
- Design and materials seen as sophisticated, backed by dedicated product testing
- Balanced, versatile feel that works well for combination sleepers and both back and side positions
- Good motion isolation and generally strong edge support across hybrid and foam models
- Cooling features and covers are effective at preventing overheating on higher-tier models
What they knock
- Firmer foam models can feel too firm or unaccommodating for dedicated side sleepers
- Stomach sleeping support is inconsistent and considered weak on several models
- Higher-tier hybrid and cooling models sit at a noticeably higher price point than entry models
- Mattress firmness numbers are hard to judge without trying the bed in person

Frequently asked
What buyers want to know.
What does Casper make?
Casper started in 2014 as a mattress company and pioneered the bed-in-a-box model. Today they sell mattresses, toppers, weighted blankets, dog beds, and bedding across North America and Europe.
What is Casper best known for?
Reviewers consistently praise Casper's foam construction for holding its shape over months of daily use without sagging or compression. The brand is also recognized for responsive returns and defect handling.
Who should buy Casper products?
Casper dog beds work well for owners of small to mid-size dogs, especially seniors or those with joint problems, who want a bed that survives washing and lasts. For mattresses, the brand ranks highest for hybrid designs and those seeking cooling and zoned support.
What are the limits of Casper products?
Casper's dog bed size range is narrow, making it a poor fit for owners of large or giant breeds. The foam is not waterproof, so spills are a concern. Color and design options are also limited.
Do Casper products need frequent replacement?
Reviewers note that Casper foam beds hold their structure over time and removable covers wash repeatedly without warping or fraying, which means they do not need replacing every few months like some rivals.
