Hi Kathy and Dan,
The foundation and frame that you have, has no give.
So, it shouldn’t need to be replaced.
Just check it to make sure that it’s still nice and solid.
Our two sided mattresses will work for Kathy, but not recommended for someone Dan’s size.
Let me recommend to you the mattress that my wife and I have.
We are, each, over 200 lbs., and our mattress is now 9 years old and still in excellent condition. I have had a very bad back for 20 years.
Yet, I sleep and wake without back pain, since having this mattress.
Here is a link to the Natura of Canada Greenspring Ultra Plush Mattress.
It has pocketed coil support and 3” of Talalay Latex upholstery.
Due to the high quality and resiliency of the components, it’s not as soft as it sounds.
In fact, about 10% of the people who have purchased this mattress have gone on to add a soft mattress topper. It is not too soft, by anyone’s standards.
We added a soft topper to ours to further cushion my wife’s sensitive hip.
I don’t recommend getting a topper right away.
I suggest waiting until you’ve had this mattress for a week before deciding if further softening of the sleep surface is even necessary.
It takes about a week for two things to happen…for a new mattress to loosen up, as a new mattress is a little stiff in the beginning…and for your bodies to get used to their new home. The second part of that can even be a little painful for the first couple of nights…as your bodies are forced back into their proper alignment.
