The Casper has a zoned support system and is softer at the head and shoulders and firmer at the back and hips. The Casper sleeps a bit cooler than the Puffy. Its perforated Airscape Foam has a bit more airflow than the Puffy’s Cooling Cloud Foam. The Casper is a bit less expensive than the Puffy.

If you’re an average-weight (150–230 pounds) sleeper or heavyweight (over 230 pounds), we recommend either mattress depending on personal preference: The Puffy is slightly softer and more accommodating, while the Nectar offers better pressure relief but may be too soft for some heavier people who share their bed.
