On the advice of my physiotherapist, I decided to buy an ergonomic pillow. I knew the reputation of the brand TEMPUR because I had tested their super mattresses and pillows at a show. It is very strong at first and may seem impossible to sleep comfortably, but gradually it takes the force of your head. For a softer comfort, we must pay the price and increase the budget for a few dollars in range. This made me decide to buy it from Amazon's offer refurbished products and also enjoy free return. I do not regret. Indeed, the package was opened and closed but the product remained impeccable. Congratulations again to the speed of delivery!
