Purpose-built for heavier sleepers: reinforced TitanCaliber coils, a genuinely firm surface, and durability the average hybrid can't match. Its luxe sibling dethroned the Helix Plus as a top heavy-person pick in expert testing. Best for back and stomach sleepers and higher body weights who need real lift and no bottoming-out; too firm for lightweight or strict side sleepers. Strong value, with a cooling-cover upgrade for hot sleepers. 120-night trial.
