The plushest latex mattress in this collection blends a four-layer design, starting with a Dunlop-based Serenity core and adding a Harmony latex topper for a soft, enveloping surface. The total height reaches 13 inches, and the top soft layer sits in its own organic casing to create a luxurious, customizable feel. This surface is especially popular with side sleepers for its pressure-point relief and soothing cradle.

This model offers extensive customization: each of the four 3-inch layers can be chosen for firmness (firm, medium, or soft), with optional side customization for Queen and King sizes. The outer cover is 100% certified organic cotton, paired with certified organic Dunlop latex and a wool flame barrier. It’s easy to assemble and compatible with adjustable bases, and a 90-day layer-exchange program helps dial in the perfect feel, backed by a 20-year limited warranty. Optional Talalay latex can also be selected for the topper or layers if desired.
