Where they differ
The Leesa is evenly medium-firm with a memory-foam recovery layer; the Casper is softer up top but zoned to be firmer under the waist. In practice that makes the Leesa the better back-sleeper bed and the Casper the better side-sleeper bed, with lower back pain sufferers in both groups well served.

- A slightly longer trial (120 vs 100 nights) matters.
Pick Casper if
- You sleep on your side or switch.
