Evidence boundary
What this comparison cannot tell you
It cannot determine which mattress your body will find most comfortable, predict individual pain relief, or establish long-term defect rates. Those outcomes require physical, version-matched testing and representative owner data.
It can show which build is documented, how firmness choices differ, what exiting the trial costs, which warranty rules apply, and what the companies still do not disclose.
Detailed research
Check each mattress before deciding
Memory Foam Hybrid
A lower-profile hybrid with a waved AirCradle memory-foam layer, lumbar crown, and size-specific pocket-coil counts. Its layer order changed after a 2023 independent test generation.
- 1.5-inch AirCradle thickness and current published layer order
- 616 queen-size coils at 15 gauge
Helix Midnight
Helix Midnight is the balanced side sleepers entry in the Core tier. That positioning is Helix’s fit taxonomy, not a result of our physical testing.
- Medium 5–6 published comfort range
- 11.5 in published overall height
