Good Morning John,
You have stepped out of, what can only be described as, a time warp.
That old S&F mattress was made at a time when manufacturers competed with one another to make a quality product.
Those days no longer exists...and haven't for quite some time.
Your old S&F mattress was one of the last great mattresses made by "The Cadillac of the Industry".
Today, S&F is nothing more than expensive junk.
S&F is not alone in this. All of the name brands have been sold...Sealy and S&F were purchased by Tempurpedic in 1013.
Simmons and Serta were bought by the same investment group.
All have loaded their mattresses with memory foam.
Memory foam is used for the express purpose of causing a mattress to need frequent replacing.
Despite all the hype to the contrary, memory foam is thee worst upholstery material ever invented.
Besides being a lousy product in terms of performance, it's also a health hazard...off gassing the toxic chemicals from which it's made.
(Adding injury to insult).
Your mistake was in assuming that a new mattress would be as good as your old one.
We used to be a Sealy/S&F retailer...exclusively. We dropped both lines when Tempurpedic bought them and turned them into junk mattresses.
We spent a good amount of time and effort at the trade shows, looking for high quality alternatives.
Over the years, we home tested a number of different mattresses...with varying results.
The one we have now, we like very much. It's 3 years old, now, and still like new....with each of us in the 225 lb. range.
I have lots of disc related back problems and my wife commonly suffers with hip pain.
For these last three years, our pains have been relieved, thanks to this mattress....The Natura of Canada Greenspring Ultra Plush.
There are 4 choices of comfort in that line, with the ultra plush model providing the greatest degree of surface comfort.
All 4 provide the same excellent, firm support.
Here is a link to that line of mattresses:
