Look for OEKO-TEX Standard 100 certification, which ensures the cover is free from harmful chemicals. CertiPUR-US certification is common for foam products, but for covers, OEKO-TEX is key. The Asthma and Allergy Friendly certification is also beneficial for allergy sufferers.
Most covers are machine washable on a gentle cycle with mild detergent. Avoid bleach and fabric softeners as they can damage the waterproof layer. Tumble dry on low heat or air dry. Always check the care label for specific instructions.
Breathability varies by model. Look for covers made with cotton terry, bamboo rayon, or other breathable fabrics combined with a waterproof membrane. Many modern covers are designed to be noiseless and breathable to minimize heat retention.
Yes, you can place a mattress pad or topper over the waterproof cover. However, ensure the cover fits snugly and the pad does not prevent the cover from sealing properly. Some covers have extra depth to accommodate toppers.
