Hello, Valued Customer, We at SUVAY would like to thank you very much for your interest in our brand and products. The "Bamboo Waterproof Fitted Full-Elastic Sheet Mattress Protector" you inquired about features a breathable, specially designed bamboo-patterned fabric surface. The liquid-proof polyurethane membrane coating on the underside of our product protects your mattress, while the soft texture on the top surface provides a comfortable experience. Lying directly on it may restrict air circulation and cause sweating; however, when used with a standard sheet, you won’t experience this issue and will enjoy a dry and comfortable sleep all day long. We are always happy to assist you and wish you healthy and happy days. Best regards, SUVAY Customer Service
