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.
