  • WHY GOTS-CERTIFIED ORGANIC COTTON MATTERS A baby’s skin is extra delicate — thinner, more sensitive, and more absorbent than ours, making it especially vulnerable to residues in fabrics.That’s why we use only GOTS-certified organic cotton. GOTS is the world’s strictest standard for textiles, verifying every step from organic farming to safe dyeing and ethical processing. No chemicals, no heavy metals, no synthetic fibers. Every stage is tested, traceable, and transparent. Certified by Control Union (License No: 1139680)
  • PREMIUM QUALITY & DOUBLE THICKNESS Made from double-knit interlock fabric with 190 GSM, this bedding offers exceptional thickness for added softness and comfort. The double-sided knit construction ensures durability and a luxurious feel — no more thin, disappointing sheets!
  • ENHANCED TEMPERATURE REGULATION: We use combed cotton with longer, smoother fibers that remove short threads and impurities. The result is a uniform, soft, and long-lasting fabric. Organic cotton also improves temperature regulation, enhances airflow, and provides year-round comfort.
  • EASY CARE & DURABILITY Machine washable at 40 °C and tumble dry safe. Made from high-quality, durable cotton that stands up to wash after wash — no thinning, no fading, no pilling, no holes. Just long-lasting softness and total comfort for many peaceful nights.
