Casper The One vs Glacier Apex Hybrid (2026)
A detailed side-by-side comparison to help you decide which mattress is right for you.
Our Pick
Glacier Apex Hybrid wins
The Glacier Apex Hybrid is the most serious cooling mattress we've tested. The layered copper, graphite, and gel system isn't marketing — it actually sleeps cold. Pair that with a lifetime warranty, 365-night trial, and fiberglass-free construction, and it earns its flagship status.
