I've been sleeping on a $300 Ikea foam mattress for 5 years in what can only be described as a relatively spartan sleeping comfort level. Basically, I got maybe 7 hours of sleep on average before I was uncomfortable enough to wake up. Since I got CopPure X-3, my average sleeping time on the weekend has gone up at least an hour, and I actually find myself wanting to stay in bed. That's all the proof I need that this was a worthy investment!
