Green Organic BOULDER FIRM Label Discover luxurious comfort with our ultimate blend of Organic Cotton and Wool Deluxe Springless Mattress. Meticulously hand-crafted from premium, US-grown cotton and rich, natural wool, this mattress offers a premiere sleep experience. The addition of luxurious wool enhances the softness of the cotton while providing natural insulation, creating a cozy and inviting retreat. Each layer is expertly hand-tufted into a soft cotton twill shell, ensuring unparalleled comfort and lasting quality throughout the night. *This mattress is a firm feel. It's available in our Standard "Green" Cotton or GOTS Certified Organic. What's the difference? While they are both made under extremely strict non-toxic conditions, the "Green" version is not GOTS certified. This means it just doesn't pay for the certificate which makes it more affordable. Regardless of which option you choose you are getting NO Dyes! NO Perfumes! and NO Toxic chemicals! **What makes this mattress so firm? The Boulder version of a tufted mattress is twice the number of tufts as the regular mattress which make it firmer. *WOOL FROM HAPPY SHEEP: We hold our shepherds to the highest standards of quality and ethics. Our sheep are raised on rotating pastures to prevent erosion and overgrazing, and their beautiful wool is never treated with chemicals. Wrapped in a layer of the finest wool we source, the Cotton and Wool mattresses are naturally hypoallergenic, and require no chemical treatments to be safe. Wool is comfortable in the summer and winter, thanks to its natural insulative properties. We recommend putting it on a box spring set or platform bed, or even using it as a floor bed. A slatted bed frame is recommended for air circulation and the slats should be at least no more than 2" - 2.5" apart from each other. When the slats are more than 2.5" apart, that may affect the longevity and comfort of your mattress. **PRODUCT FEATURES: *Layered US-grown organic cotton and wool expertly built inside of a cotton twill shell and hand-tufted in place. *Balanced support with plush softness from cotton and/or wool tufted layers *Hypoallergenic, resistant to allergens, ideal for sensitive sleepers and those who prioritize health and sustainability *EASY MAINTENANCE: flip every few months and add a topper for extra plushness **DETAILS: *DELIVERY: rolled and compressed for easy delivery; expands fully within 72 hours. *USAGE: not suitable for Bifold frames due to its softness.
