6 inch mattress

Many 6-inch crib mattresses offer a dual-sided design with a firmer infant side and a softer toddler side, while other 6" models are sold as uniformly firm or extra-firm throughout.

Covers vary by model but commonly include removable, zip-off outer covers that are machine-washable or waterproof sleep surfaces. Other models specify spot-clean or wipe-clean care instructions.

Common certifications and standards shown for 6-inch mattresses include GREENGUARD Gold, CertiPUR-US, OEKO-TEX STANDARD 100, JPMA certification, and references to meeting ASTM or similar safety/testing standards.

Crib-sized 6-inch mattresses in these listings typically weigh between about 10 and 26 pounds; an adult 6" memory foam queen option is listed at about 40 pounds.

Both construction types are used in 6-inch mattresses: some models use coil systems (pocketed or Bonnell), while others use all-foam cores such as memory foam, high-density polyurethane foam, or latex.

Most crib-sized 6-inch mattresses are marketed for infants and toddlers, with common suggested ranges including 0–3 years, 1–5 years, and up to 0–6 years in some listings. Separate 6" options labeled as adult mattresses are intended for adult use.

Warranty lengths vary widely across 6-inch mattresses, ranging from about 1 year up to 10 years, with some listings indicating lifetime limited warranties.
