Side sleepers of most body weights — the position tested 8.5–9 across all three weight bands, the strongest fit result. Consider the limitations: You sleep on your back or stomach and weigh over 230 lb — testers found it too soft to stay supported (5.5–6/10 fit).

Side sleepers of any weight — 9 to 9.5 out of 10 in every band, and the deeper memory foam is exactly what the Classic Hybrid’s lighter side sleepers were missing. Consider the limitations: You are upgrading for cooling. Temperature control measured 7/10 — identical to the Classic Hybrid — so the "2x cooling fibers" claim did not show up in the test result.
