请帮我翻译一段话,请不要用软件翻译!
We have owned Tempur Pedic products for 15 years and have been more than pleased with every one of them except these pillows. I bought the Grandbed and the pillows to match, we love the bed but the pillows never have any give. We have to keep our regular Tempur Pedic pillows for sleeping. I only use these for decoration.Huge waste of money for that purpose. I have complained to the company when I have called to purchase sheets and they just glaze over it. If you want great sleep, buy a different one of their pillows.
