The White Lotus Green Cotton & Wool Latex Core Mattress is a natural cotton and wool mattress built around a 3-inch natural latex core, surrounded above and below by layers of Green Cotton and wrapped in approximately 1.5 inches of pure wool. The latex core adds responsiveness and a medium-firm feel that is softer than the cotton-only Dreamton, while the wool wrap serves as a natural flame retardant, dust mite repellent, and year-round temperature regulator. Handmade by White Lotus and compatible with platform beds, box springs, and bi-fold frames, this mattress is available in Twin through King.
