Materials

Our mattresses are crafted with premium materials designed for comfort and durability. Depending on the model, you may find layers of cooling gel-infused memory foam, natural latex, individually wrapped coils, and breathable organic cotton covers. Each material is carefully selected to provide optimal support, pressure relief, and temperature regulation throughout the night.

Dimensions

Mattress dimensions vary by size. Twin: 38" x 75", Twin XL: 38" x 80", Full: 54" x 75", Queen: 60" x 80", King: 76" x 80", Cal King: 72" x 84". Height and weight vary by model. Check the individual product listing for specific measurements. All our mattresses are designed to fit standard bed frames and foundations.

Care Instructions

To keep your mattress in top condition, rotate it 180 degrees every 3-6 months to ensure even wear. Use a mattress protector to guard against spills and stains. For spot cleaning, gently blot with a mild detergent and warm water. Avoid soaking the mattress. Allow adequate ventilation by occasionally removing bedding to air out the mattress. Do not fold or bend the mattress, and always use a supportive foundation or bed frame.
