  • OMG! Absolutely the best bed ever!!

    I have terrible back trouble and never sleep more than 4 hours. The first night I slept on this mattress, I slept for almost 9 hours! Without waking! It was crazy. I was so comfortable. I have arthritis and fibromyalgia and just had back surgery 3 months ago. Absolutely the best bed ever. I had a traditional mattress with foam topper before and a Sleep Number bed, which are horrible by the way, and this by far is the best mattress I have ever slept on. I wake up refreshed and not even needing coffee! WOW! A definite must buy!!
