Half a year ago I bought 2 of these pads. After six months, the keels of feathers came from ticking. There were many, and they stung so are right at it. I complaining the cushion at the company, but they did not respond. As I turned to Amazon and was excellent helped. The next day I had 2 new pillows. This I test now. Currently, after about 3 weeks they are still ok.
