The Firmest Mattress We Make The Boulder Dreamton is a deluxe upgrade of our Green Cotton & Wool Dreamton—with 15% more cotton and double the tufting for exceptional firmness and durability. It's a mattress built for support, with a dense Green Cotton core and a thick wrap of our luxurious, chemical-free natural wool. This is the mattress to choose if you want a solid, stable surface that keeps your body aligned and supported through the night. Available in all standard and custom sizes, from 6" to 8" thick. What Is Green Cotton? Green Cotton is a more affordable, U.S.-grown alternative to organic cotton. It isn't certified organic, but it's still clean, safe, and firm—without any of the nasties you'd find in conventional cotton. That means: NO dyes NO perfumes NO flame retardants Grown responsibly in the U.S., Green Cotton is a smart, chemical-free choice that saves money without compromising on purity or performance. Wool from Happy Sheep At White Lotus Home, our wool comes from sheep raised on rotating pastures, ensuring ethical animal treatment and land sustainability. This wool is: Naturally antimicrobial & dust mite resistant Free from chemical treatments or flame retardants Thermal regulating—cool in summer, warm in winter Wool provides a cozy, breathable layer and helps the mattress meet flame safety standards naturally. What to Expect from Sleeping on the Boulder The Boulder Dreamton is a spring-free mattress, which means no motion transfer between sleepers—a big plus for couples and pet parents. With its ultra-firm feel, it's especially beneficial for those with chronic pain, spinal alignment needs, or anyone who wants a mattress that truly holds you up instead of letting you sink in. How to Use It To get the best performance and longevity from your mattress, we recommend placing it on a: Box spring Platform bed Slatted bed frame (slats no more than 2"-2.5" apart) Directly on the floor Using slats spaced wider than 2.5" may reduce support and shorten the mattress's lifespan.
