So far so good. I have not washed it yet and not sure if I think it’s necessary. (Some reviewers say it stunk after washing then smell went away when it dried but it’s cold and wet here so maybe I’ll wait until summer) It doesn’t have any weird odors to it and I will have my sheets on it anyway.  What I really love about this wool fleece pad is that it’s not bumpy and lumpy like other ones I had ordered from the stitchings I think, and I ended up returning.  So this pad was a little more expensive than what I initially wanted to spend on this type of thing, but I think it’s worth it. Just knowing that it’s smooth and not bumpy was my main concern, and Wayfair was also very prompt and attentive when I inquired about that.
