cliffwade, It's now been about 2 weeks or so since the wife and I got our first memory foam mattress, which we decided on a Nectar brand.
During these two weeks or so, I've been sleeping considerably better. I sleep a bit later than I was there for a while as I now wake up around 6am instead of between 4am - 5am.
I also don't wake up with a sore back, headaches or feeling like I want to immediately go lay down on the couch and take a nap. (cont...)
