I purchased a Series 600 in May, my wife and me really love the bed. I like soft mattress, but my last mattress made me suffer.
until i went to mega courts to look for mattress, i knew about this brand. So many brands around, i also dunno which one to select,
but at least the computer, tell me what is the postural support i required, and i choose the Series i feel comfortable on.
I recommended 2 of my friends to buy from them, so far so good. We are still friends!
