Pretty good, especially for the price
There was initially a strong natural wool smell which I wasn't expecting. The smell of lanolin. A delicate wash and a few days later it's almost gone. The pillow got a lot lower after washing, but I was expecting that and it actually works better for me. I was sent a defective one (some yellowing and loose threads), asked customer service about it and they immediate apologized saying it shouldn't be like that and sent me a new one. Didn't even need to sent the defective back! So hopefully if it doesn't fall apart I have 2 very comfortable natural wool pillows! I know people say that you don't need to wash pillows, but honestly I don't trust a thin piece of fabric to block 100% of bacterial, oil, contaminants etc. so finding a natural, inexpensive and Aussie made washable pillow has been a great change. Highly recommended!
