These are the most durable most washable organic pads around. Most companies use just carded organic cotton. Unfortunately after several washes it starts to lump up. Our quilting is needle punched organic cotton. This holds the fibers together through all that washing and drying in the machine. No special care needed. Our outer organic cotton sateen feels great, not scratchy. These organic Cotton quilted mattress pads have organic cotton inside and out. Protect your mattress from the moisture your body gives off at night by using a pad that you can machine wash and dry. Perfect to use with the wool moisture pad.
