At Charleston Mattress, we are committed to building every mattress with the finest U.S.-sourced materials. We carefully select components that deliver support, comfort, and durability—while also being environmentally responsible. Once crafted, we price our mattresses transparently and affordably, so more people can enjoy a better night’s sleep.
All Materials Sourced in the U.S.A.
Every material used in a Charleston Mattress® is sourced from American companies with long-standing reputations for quality and innovation.
Coils are made by Leggett & Platt in St. Louis, Missouri, using up to 95% recycled steel. Each year, nearly one million tons of scrap steel are repurposed into new mattress coils.
Renew™ Foam is produced by Carpenter Company in Richmond, Virginia, using Natural Foam Technology™. This bio-based process reduces environmental impact while maintaining the consistent performance our customers expect.
HARVEST® Foam is manufactured by Future Foam, with facilities in High Point, North Carolina, and Bluffs, Iowa. It blends natural soy-based oils with traditional polyols, supporting farmers and reducing reliance on petroleum-based materials.
Natural Latex is processed by Mountain Top Foam in Mountain Top, Pennsylvania. Their continuous-pour method keeps latex in constant motion during production, ensuring quality and preventing settling. Naturally resistant to mold and microbes, latex is also biodegradable.
Quilted Covers are crafted by Culp in High Point, North Carolina. For more than four decades, they have been leaders in upholstery fabrics. All covers meet the STANDARD 100 by OEKO-TEX® for safety and quality.
Certified Safe & Responsible
All foams used in Charleston Mattress products carry the CertiPUR-US® certification, which ensures:
All foams used in Charleston Mattress products are CertiPUR-US® certified, ensuring they are low in emissions for better indoor air quality and completely free from harmful substances. They contain no ozone-depleting chemicals, no formaldehyde or phthalates of concern, and no PBDEs or heavy metals such as lead or mercury.
Caring for Your Mattress
To protect your investment and extend the life of your mattress, rotate it regularly to encourage even wear and always use a proper foundation or frame with center support for queen and king sizes. We recommend using a breathable mattress protector to guard against spills, stains, and allergens. For cleaning, avoid harsh chemicals; instead, spot clean with mild soap and water when needed.
