I LOVE this mattress! I previously owned a Tempur-Pedic which was over $2k. It was great except for the fact that it got real hot and the price was so high. I then tried a cheap version from a local furniture store but it was only 6 inches thick and eventually started adding to my back pain. I couldn't take it anymore so I started to research mattresses and came across this one. The price and reviews made it hard to pass up. I never thought to order a mattress online before and my husband was skeptical but we decided to take a chance. We are so glad we did! The thickness of this mattress is good and the medium firmness is perfect! We've slept on it for 3 nights so far and I am already noticing a reduction in my back pain and I'm also experiencing deeper sleep. It's so comfy that it's hard to get out of bed in the morning! I highly recommend this mattress!
