longevity of memory foam

I'm wondering if anyone can tell me how long (in general -- and assuming higher densities and decent quality) memory foam toppers can be expected to last. And how does one tell when they are 'losing their memory' and need to be replaced? I have an Overstock 2" topper that is a year old -- supposed to be one of the good ones. Right now our bed is so uncomfortable I can't tell much about how the mem foam is functioning, but once our latex from FBM gets here I'd like to see how the memory foam fares in the mix.  I want to know what I should be looking out for to tell when it is no longer doing what it's supposed to. 

thanks!

I resonate with your question. Unfortunately I cannot help specifically, but I'll share what little I've been learning. I ran across an interesting article yesterday that provides atleast a relative understanding of how different mattress toppers might compare. see the following link: http://www.beddingcomponents.com/pdf/innersprings/softech-chart.pdf

Wow - that really is an interesting link. Correct me if I'm wrong but is that a topper made of pocketed coils? First time I've seen that!

Ok there is LOTS of crazy and interesting talk here http://www.bedtimesmagazine.com/Articles/2011/August/coverstory.html about the next (supposed) latest great thing in mattress. 

This quote was interesting -- considering it was their change in their products that led to the "ubiquitous" problem beds have with impressions.

 

"Low-profile innersprings are helping mattress makers battle the ubiquitous body impression problem and springs suppliers proudly extol the virtues of their product in preventing this cause of so many mattress returns.

“We are all charged with making sure our mattress products don’t come back due to body impressions,”

I've had 5 mattresses in home since May this year.  All of them 3 to 4 weeks.  Every one of them forms 'normal body impressions'.  I can press on different areas, and they all become a little softer in the area where hips and torso lay.  This includes memory foam, latex and a Stearns and Foster innerspring with its quilt batting and regular comfort foam.

I've said it before and here it is again - nothing was easier on my right shoulder than memory foam.  The all latex had good support for sure, but pressing down on it, I could feel the immediate response and resilient pushback.  It was fairly easy on my left side, but too much pressure on my right.  I suppose most people without a bad joint can sleep on all latex.  If I were to decide against the TP, I would go back to the all latex and stick with it, but I doubt that will happen.   btw, it was 80 F in my room at 11pm and I didn't have a temp problem sleeping in the TP.

I wanted to bump this up to ask the question of whether or not I need to put in additional support under our box springs? If I did so, should I just wedge some 2x4's on end (cut to size of course) in the center of each box spring? (we have a split king) I just can't really find any info about this online or here and don't know if it's needed or not. Our box springs are about 6-7 yrs old and I think they are fine -- but I don't know how I'd know if they weren't!

I should add that even with our new latex foam (from FBM -- need to start another post on that!) the bed is still a bit firmer in the very center. I don't know if that's because it's the area with the least wear (ie we tend to sleep on our own sides) or if it's from the support of the center rail on the metal bed frame between our split box springs.

I just sent back my 3 layer all latex bed today.  I had it on a twin XL S&F box spring with frame center rail that was completely supporting the head to toe slat of the box spring.  The latex was softer in the middle of the bed, firmer on the sides and there was a tendency to kinda sorta make me roll back to center if I scooched close to the edge.  One of the reasons I returned it.

Think I said this above, but I've found that all mattresses break in where you sleep and are softer in that area.  Even the Tempurpedic Cloud, however, if I lay near the edge of it, I'm securely in place.

Should you put a piece of wood to support the center slat?  I don't know.  Sounds like a pain to do.
