When that Bruno Clair Stearns & Foster mattress was made, this was a legitimate industry.
Manufacturers competed with one another to make a better mattress.
Retailers competed with one another to bring those mattresses to you at a better price.
All of the name brands could be trusted to provide quality, with S&F among the best of them.
In fact, S&F had been considered "The Cadillac of the Industry" for many decades.
Those days are long gone....starting around the turn of the century.
Memory foam was introduced a couple years before. Name brand mattresses went from being two sided to one sided, a couple years after.
As the years went by, the name brands began adding memory foam to some of their mattresses.
Later, all of the name brands were sold to investors, who use memory foam to increase profit and recoup their investment.
As it became clear that there was lots of money to be made, in this industry, new brands sprang up...like your Nolah mattress.
Every one of them claimed a product that was the latest greatest thing...claiming "State of the Art" technology.
One line of BS after another produced interest from people, like you, who fell into all the hype.
(That was not a personal attack. You are but one of millions who have been taken in by all that hype.)
All of the name brands, once sold, became companies making products that need frequent replacing...thanks to all the memory foam.
Sealy/S&F was purchased by Tempurpedic in 2013. By January of 2014, S&F went from "The Best" to being nothing more than expensive junk.
As a Sealy/S&F retailer, I was greatly disappointed. We dropped both lines and went shopping at the trade shows for something better.
Good quality wasn't easy to find. You'd be amazed at all the new brands that popped up...all promoting memory foam.
We did find some that suited my desire for quality.
One, was The Wolf Company...which turned out to be the oldest mattress manufacturer in the country, that has been owned and operated by the same family...since 1873. They make a good quality mattress, but nothing like the quality of those old S&F mattress.
The best, we've encountered, is an old brand from Canada..."Natura".
My wife and I have been sleeping on a Natura of Canada Greenspring mattress for the last 3+ years.
We are heavier than you. My wife with a sensitive hip and me with lots of disc related back problems.
We sleep without pain, and this mattress is STILL in like new condition.
Their Ultra Plush model is what we have and what I am recommending for you.
