It's been too hot! We aren't going to walk when the outside temp is 90 plus. Shoot, we won't even take our boat out when it's that hot. Anyway, we really aren't walkers that much at all. We will walk thru a grocery store or, if we are in Vegas, around/thru the casinos, but other than that..........just not that much. It can be very hard to get some exercise when a person is tired from the lack of sleep the night before. Other than our boat, exercise isn't one of our favorite things to do. Really.
It's not the mattress, Babs, it's the Topper that lays on top of the mattress. I can sometimes wake up in the morning with some tailbone pain. We have both a 3 inch and 1 inch Toppers on the top of the mattress. Both are fairly old. When we bought our last mattress, we found out that it was way to firm, so that's why we bought the Toppers. For quite a while, we bought slept fine, but now........ One other thing, if it turns out the new Topper doesn't work, nice chances out of ten, it's her job and getting up too early. We will find that out once we get the new Topper and sleep on it.
No topper, just the right firmness of a memory foam mattress protected with a liner and a pad that adds a nice feel to it. Mine is adjustable and I sleep with my upper body elevated and on my back and don't change positions.
