We're looking for a reliable manufacturer to produce a custom fitted-sheet style mattress protector for our brand. We need it in white, specifically for a queen size with dimensions of 60 inches wide by 80 inches long and a depth of 23 inches. The fabric should be 100% cotton on top, with a 100% non-woven bottom and filled with a down alternative. Key features include a deep pocket design, a pillow top, and washable material. Please ensure the stitching is strong, particularly where the hoop and hook are attached, to withstand regular stretching during laundry. The protector should be designed to accommodate a 21-inch deep pocket with 49 oz of elastic and hollow down alternative microfiber for enhanced softness. A 30 oz down alternative filling will provide comfort while the 300TC cotton surface is breathable and absorbs sweat, making it skin-friendly. Additionally, we'd like the deep pocket to stretch easily up to 21 inches using 130GSM single-track elastic fabric. Looking forward to your response!
