Experience is the most important factor in selecting a mattress, so before discussing how it is made, let me tell you how it feels. Just to be clear, this experience is based on a few minutes spent trying some out at a retail store. The Tempur-Pedic people had recommended lying down on it for 7 minutes and you will be happy. When you get up, the mattress slowly regains its shape, and supposedly that resilience lasts for its life. TEMPUR material responds to each sleeper’s unique shape, weight, and temperature, and automatically adapts to support each sleeper’s body. Whether you spend your nights sleeping on your back, side, stomach, or you change positions throughout the night, TEMPUR material conforms to your body to ensure you get the perfect amount of comfort and support in every position.Most comfortable mattress you can sleep on and if you have back pain or muscle spasms Tumpur-Pedic mattress is the best for you.
