Overview
The Casper Original is one of the most recognizable bed-in-a-box mattresses on the market. First launched in 2014, it has gone through several updates, and the 2025 version features an improved three-layer all-foam construction designed to balance comfort with support.
Comfort and Feel
The Casper Original delivers a balanced medium feel that we rate at 6 out of 10 on the firmness scale. The top AirScape foam layer provides initial cushioning, while the memory foam transition layer contours to your body for pressure relief.
Side sleepers will appreciate how the mattress cradles the shoulders and hips without creating pressure points. Back sleepers get adequate lumbar support, though those over 230 lbs may find they sink a bit too deep.
Motion Isolation
This is where the Casper Original truly shines. The all-foam construction absorbs movement exceptionally well. During our partner disturbance tests, the sleeping partner reported almost no disruption when the other person changed positions.
Temperature Regulation
The perforated AirScape foam helps with airflow compared to traditional memory foam, but this is still an all-foam mattress. If you tend to sleep hot, you may notice some heat retention. Consider a cooling mattress pad or look at hybrid alternatives.
Edge Support
Edge support is the weakest area for the Casper Original. Sitting on the edge causes noticeable compression, and sleeping near the perimeter may feel less secure. If you frequently sit on the side of your bed or sleep near the edge, a hybrid mattress would serve you better.
Who Should Buy the Casper Original
The Casper Original is an excellent choice for side sleepers, couples who need motion isolation, and anyone looking for a well-rounded mattress at a reasonable price. Its balanced medium feel works for most body types in the 130-230 lb range.
Who Should Skip It
Stomach sleepers over 200 lbs, hot sleepers who need maximum cooling, and anyone who prioritizes edge support should look elsewhere. We recommend the Saatva Classic or WinkBed for those needs.
