Firmness Info Three levels of firmness let you decide the level of support you need. It rates as a medium-firm mattress, but really combines the best of both firm and soft products. It's the perfect balance of comfort and support. Our provides superior pressure relief, with little bounce, and zero motion transfer. Essentially you feel like you're floating on a cloud. Unlike other memory foam mattresses, we sped up our foam's response rate so that you don't sink too far down into the core, and so you don't feel stuck in the foam. Two comfort levels within the one mattress, 80% of latex customers choose a Luxury Plush comfort range (a 4-5 on the firmness scale). It conforms and supports your body effortlessly while still maintaining an ultra-luxurious, plush feel. The Gentle Firm side is 18% firmer than Luxury Plush, for those who want a slightly firmer feel. Gentle Firm still provides uplifting, pressure-free support (a 7-8 on the firmness scale). How do you choose a Zenhaven comfort level? You simply flip the mattress over.

  • 6" 1.8lb Density 30 ILD Base Foam.
Pure tree-tapped latex and advanced 2-in-1 comfort innovation create the ultimate sleep experience.
  • 1" Organic Wool Layer (both sides of Zenhaven have a flame-retardent barrier made of 100% organic New Zealand wool, not chemicals, which also adds breathability and moisture-wicking properties)
  • 2x 1.5" 100% Talalay Latex "5-Zone" Comfort Layers (N2 - gentle firm side, N1 - luxury plush side)
  • 2x 3" 100% Talalay Latex Support Cores (N4 - gentle firm side, N3 - luxury plush side).
Comfort Info Patented Energex™ is paired with TitanCool™, a water-based surface infusion with high conductivity properties that draw excess heat away from the body, maintaining optimal comfort for each individual sleeper. An infusion of copper helps promote an antibacterial sleeping environment.
Combining an elite performance fabric, registered with the FDA, with the patented advanced cooling of TitanCool™, the Spartan helps you reset and rejuvenate quicker by harnessing and recycling the body's natural energy throughout the sleep cycle.
Four layers of high-density memory foam, refined through two years of R&D and 27 rounds of prototyping to provide the perfect balance of comfort, support, responsiveness, and breathability. Zenhaven's American-made Talalay latex offers a range of health benefits. It's naturally hypoallergenic and resistant to mold, microbes and dust mites. It contains no volatile organic compounds or other harmful substances found in chemical-based bed foams. And it has a uniquely resilient feel that elevates and conforms to your body for perfect support, total comfort, and a truly restorative night's sleep.
Support Info A transitional layer of swirl memory foam provides enhanced contouring and deeper compression support with added cooling. Our four-layer weightless foam system combines a plush top layer with increasingly firmer base layers, to deliver an optimal combination of comfort and support. We refined our mattress through 27 rounds of testing, optimizing for pressure-relief at all five key pressure points. We tested a range of body types and sizes, ensuring that the W1.27 would be supremely comfortable for almost all people, while still providing full body support. By varying the size and distribution of the "pinholes" formed during the Talalay process, we created a seamless mattress layer with 5 distinct zones of density, providing Zenhaven with firmer support beneath the torso and shoulders and more subtle support elsewhere. The result is pressure-free support and better spinal alignment.
Comfort Specs A second 2" layer of hyper-elastic TitanFlex™ foam provides cloud-like comfort with immediate response technology that adjusts to your body each time you move.
A patented phase change molecule surface infusion of TitanCool™ maintains body temperature at an ideal 88 degrees.
To keep our mattress from overheating, we developed an extraordinary new foam called 3BELOW™. It's a fully breathable, open-cell material, infused with heat-conductive gel particles. That means it actually draws heat from your body and disperses it throughout the mattress so it escapes more quickly. As a result, the W1.27 sleeps three degrees cooler than other foam mattresses, right in the sweet spot for deep, uninterrupted sleep. Latex has an open cell structure that allows air to circulate freely, countering body heat and providing cool, comfortable sleep. This natural air flow gives you a mattress that's seven times more breathable than other types of latex.
Support Specs A 1.5" top layer of patented CopperGel Energex™ foam provides responsive contouring with targeted pressure point relief and the highly conductive, antimicrobial properties of copper.
A third 1" Swirl Visco-Elastic Memory Foam layer provides enhanced contouring and deeper compression support with added cooling.
An 8" base of up to 1,189 individually encased Quantum™ Edge coils delivers ultimate pressure point relief while decreasing motion transfer.
The core of our W1.27 is 100% viscoelastic memory foam. We tested every possible material, including memory foam, latex foam, coils, coil / foam hybrids, hand-rolled cotton, horsehair, and found that memory foam gives us the greatest precision in crafting a truly great product. We've made the best memory foam mattress on the market. The W1.27 achieves unparalleled balance, meaning that it's supremely comfortable to lay on, but also provides better body support than other products. Natural latex is the best-kept secret in sleep, and once you have experienced it, nothing else will do. It instantly responds to every curve of your body for pressure-free support and incomparable comfort on both traditional and adjustable bases.  A Zenhaven exclusive, our Talalay latex comfort layers feature a proprietary 5-zone design that gives you firmer support where you need it for the ultimate in comfort and spinal alignment.
Fabric Specs An exclusive performance top, made of patented Nanobionic RE-3™ technology, transforms your body's heat into waves of energy, reflected back to you through the medium of fibers - using technology that has been clinically proven to increase oxygenation and improve circulation as well as sleep quality, health and wellness. Organic Cotton Cover
A cover of quilted organic cotton completes one of the world's healthiest and most comfortable natural latex mattresses.
