Our take on the Casper Sleep Original California King Mattress

The Casper Original is an all-foam mattress with four layers of memory and polyurethane foam, a tight top and an 11-inch profile. It is built with firmer foam under the hips, waist and lower back to keep the spine aligned, and it has a medium-firm feel with a little bounce rather than a deep sink. It suits side and back sleepers and couples who want a simple bed-in-a-box without springs. Against hybrid rivals it trades springy edge support and airflow for a quieter, motion-isolating foam build, and owners generally report it holds up well over several years.

About the Casper Sleep Original California King Mattress

The Casper Sleep Original is an all-foam California King mattress. It is built from four layers of foam and has a tight top. The fill material is memory foam, and the construction is breathable.

Firmer foam sits under the hips, waist, and lower back to support spinal alignment. The feel is Medium-Firm, with a responsive bounce.

The mattress comes in a box. To set it up, take it out of the box and unwrap it. It then decompresses, and jumping, walking, or sleeping on it can speed this up. It is backed by a 10-year limited warranty.

Questions and answers

Is the Casper Original good for side sleepers?
Yes. The medium-firm foam cushions the shoulders and hips while the firmer zone under the lower back keeps the spine aligned. Back sleepers also tend to do well on it.
Does it need a box spring?
No. It works on a platform bed, slatted frame or adjustable base. A solid, supportive foundation is what matters.
How long does it take to expand?
It decompresses within hours of unboxing. Walking or lying on it speeds the process, and it reaches full height within a day or so.
Is it hot to sleep on?
The foam is breathable, but all-foam beds retain more heat than coil hybrids. Hot sleepers may prefer a cooler cover or a hybrid.
How does it compare with the Casper hybrid?
The Original is all foam, so it isolates motion better and has a plusher feel. The hybrid adds coils for more bounce and stronger edges.
What is the warranty?
Casper backs it with a 10-year limited warranty covering manufacturing defects.
