After serching for a new mattress and finding prices way out of my budget... I am beyond pleased with the one I picked. It surprised me to have it come rolled up but after getting it on my box springs and letting it lay open for only 10 hours, I slept on it and managed to sleep through the entire night, never waking once for the first time in over a year. I have a herniated disc plus athritis in my lower back and my old mattress caused me more pain and discomfort than anyone could imagine. Thank you Overstock for helping me find a great bargan and a beautiful mattress.
