Here is the link for the Sealy Posturepedic you asked about.
The model name is different at every store and most hotels.
So, to continue to shop for it at other stores, you’ll ask for a “Classic Posturepedic Level A-3, in Plush”.
Old mattresses are two sided. They all went one sided about 13 years ago.
And since then, they’ve been adding memory foam…designed to sell and need frequent replacing.
When I meet someone, like yourself, with an old mattress that is perfectly fine, other than being too firm, we suggest considering a latex topper for it, in lieu of buying a new mattress.
Latex is and has been the best upholstery material available, anywhere on the planet for the last 100 years. This will make what you have comfortable…sleeps cool, and lasts for many years…for a fraction of the cost of a new mattress.
The one to choose is the EverEden All Natural 2″ Soft Talalay Latex Topper.

Lastly, I want to address your neck pain.
This issue is better addressed with a pillow.
Our PureBliss 100% finely chopped latex does the best job of relieving chronic neck pain.
The finely chopped latex is easy to mold around your head and neck.
I use one at home. It is the only thing that has relieved the pain of arthritis in my neck.
