Materials & Technology

When you hear “ergonomic support,” you might think of fancy office chairs or standing desks. But honestly? Your bed plays an even bigger role in how your spine feels every day. In fact, after testing dozens of mattresses over the last five years, I’ve learned that one of the single most important materials is high-resilience foam — the kind that bounces back instead of sagging, and keeps your back aligned while you sleep.

Whether you’re dealing with mild morning stiffness or serious back pain, understanding what high-resilience foam does — and why it works — can change the way you shop for your next mattress.
