**Thuma Hybrid Mattress Review: A Firm, Eco-Conscious Choice for Select Sleepers**
Thuma, a brand best known for its elegant, tool-free bed frames inspired by Japanese joinery, has expanded its product lineup with the introduction of the Thuma Hybrid Mattress. The brand’s bed frames have long been favorites among WIRED’s review team for their minimalist design, sturdy construction, and easy assembly. With the launch of the Thuma Hybrid Mattress, the company aims to offer a sleep system that matches the high standards set by its furniture. But does the new mattress live up to Thuma’s reputation for quality and innovation?
**A Five-Layer Hybrid Build**
The Thuma Hybrid Mattress stands out for its complex, five-layer construction—more than typical hybrid mattresses, which usually feature only two or three materials. The mattress is topped with a breathable, temperature-regulating cover made from eucalyptus-derived Tencel, spandex, and rayon. Beneath the cover lies a layer of organic wool, which serves as a natural fire barrier and provides additional cushioning without trapping heat, unlike traditional fire-retardant materials. This is followed by a “biobased” memory foam layer that adds pressure relief and softness, though it isn’t entirely plant-based. The next layer features GOLS-certified organic Dunlop latex, known for its firm, bouncy feel. At the mattress’s core are pocketed coils made of recycled steel, each individually wrapped to offer targeted support and limit motion transfer. The edges are reinforced with slimmer, firmer “pencil coils” to provide secure support when sitting or lying near the sides.
While the mattress primarily uses natural materials, it is not fully organic. The memory foam includes plant-based oils, but is not entirely derived from renewable sources. For eco-conscious consumers seeking a completely organic sleep surface, this may be a drawback. However, Thuma’s commitment to sustainability is evident in its sourcing practices. The latex used in the mattress comes from the same rubberwood trees as the brand’s bed frames and other furniture, creating a closed-loop system that minimizes waste and improves traceability. Additionally, the mattress is hand-tufted, a detail discovered during setup, which helps keep the internal layers from shifting over time and maintains structural integrity.
**Simple Setup and Minimalist Appeal**
The Thuma Hybrid Mattress arrives as a bed-in-a-box and is easy to set up—on par with most mattresses available online. Although Thuma offers a white-glove delivery option, the setup process is straightforward enough that most users won’t need it. The reviewer noted minimal off-gassing from the mattress itself, with any odors dissipating within 24 hours. When paired with Thuma’s Classic Bed Frame, the mattress’s low 10-inch profile contributed to a clean, modern look that didn’t overwhelm the space, even in a king size.
**Firmness and Feel: Who Is It For?**
The Thuma Hybrid is available in three firmness options: Plush
