Exactly what I was looking for for my daughter's bed. She suffers from allergies and I can already tell this is much better quality than mattress protectors we've purchased in the past. The weave is very high quality which is important for blocking dust mites, pet dander, etc. but it feels very breathable and soft at the same time. I love that it is a full zippered encasement so the entire mattress is protected and there are no chemicals or treatments on the fabric. Just natural 100% cotton. Highly recommend!
