Advice from our Expert on a "still awesome" mattress question

Hi Pete,
I've been searching for a mattress that will last longer than all these horrible reviews I keep reading.  
I've had my current Cal King mattress. a Serta Perfect Sleeper, Artistry Collection for over 20 yrs. 
Yes, it's still awesome and I'm still sleeping on it and of course they do not make them anymore. 
I'm about to move into my new house, so I'm ready to say goodbye and replace it.  
I've been looking at Stearns and Foster and after doing reviews on numerous websites and the BBB I learned a few things:
 
1.  Weight restrictions on beds.  Some beds only hold the weight of 500 lbs., so if you and your partner's combined weight exceed this don't buy certain mattresses.
2.  Make sure the frame for the bed will hold you and your partner and the weight of the mattress and box springs.  
3.  Make sure if you do not purchase a box spring that you pay attention to the frame the mattress will sit on.  
The spacing in the planks will also cause the mattress to sag in time.
 
With this being said, I was told by numerous people in the mattress industry, as well as reviews, that Stearns and Foster mattresses sag in the middle because they weren't made with enough support in that area. 
Tragic, most people eventually migrate to the center of the mattress during the night.  
So, moving on from them. It just seems every mattress I look at the reviews always state how the bed sags within the first 2-3 yrs. of owning it.  
I've tried three mattresses at this store in Huntsville, AL. 
Of course, there is no literature online about them and the company's salespeople do not know anything about them, except for the fact that they were made exclusively for that store. So, I can't even read reviews on them.  
I am looking for a pillow top mattress over 14" high, med/firm
Thanks, Tiffany
 
Hi Tiffany,
The only thing that’s true, about the information you have so far, is that most mattresses aren’t made nearly as well as they had been. Your notion as to why is completely wrong.
What most of today’s mattresses have in them that your 20 year old Serta doesn’t have in it, is memory foam upholstery.
 
All of the mattresses that you’ve asked me about are upholstered with memory foam.
All of the name brand mattresses that you could once trust to make a quality product have been sold. 
Sealy and Stearns & Foster were purchased by Tempurpedic.
The investment group that bought Serta also bought Simmons.
 
Memory foam is specifically designed to cause a mattress to need frequent replacing. 
Not only is it a poor quality product, memory foam also off gasses the toxic chemicals from which memory foam is made…creating a health hazard.
 
And, a mattress with a pillowtop will show wear faster than one without.
 
What you say you want won’t work for you for very long.
Since your mattress is "Still Awesome" I recommend that you take it with you when you move.
DO NOT BUY A NEW MATTRESS!
 
Thanks, Pete 
 
A waterproof mattress protector will extend the life of any mattress, keeping it clean and dry.
