Geez, haysdb--chill out!

First I want to say I have no relationship to anyone using the name cloud9 selling anything on Ebay or anywhere else. If I was selling memory foam there I wouldn't be buying retail at Mervyn's or Overstock.com. It seems like you got the runaround fron this vendor and you're coming down on me because we have the same username.

That being said. I get it. Making an "informed" decision is very important to you. That's fine to a point--we use this forum to keep informed, but I'm not sure that most people want or need to be quite that "informed." In fact, I kind of doubt most people make their bedding decisions with a 4-function calculator.

I bought a latex mattress kit after researching the subject to death and thought I was making an informed decision. Adjustable firmness, comfort exchanges--how could I go wrong? The only thing I didn't consider was that I just couldn't sleep on the thing without a backache.

I didn't waste another two months pointlessly over-researching the next mattress I bought. Sometime you just have to back away from all the facts and concentrate on how it feels.

Verysleepy just wanted to soften up a too firm mattress. It doesn't have to be rocket science. Unless, of course, you need it to be. I didn't get the impression from her post that she did.  So if you want to split hairs and insist it's not visco (according to the Polyurethane Foam Association... whose members are... Tempurdedic... Sensus..?) unless it conforms to a Tempurpedic or Sensus model of what visco is "supposed" to be, or that most foam being sold is "garbage" be my guest.  

Frankly I don't care what the density or the ILD is, and I'm going to make a leap of pure faith and accept that it's 4 lb foam because that's what it was sold as. Sorry I left my scale and calculator at home when I went shopping so I couldn't verify it. Oh well.... What ever the hell it is, it's wonderfully comfortable and  that's all that's really important to me, so I am recommending it on that basis. Some people just want comfort. Not calculus.

And yeah, I did offer alternatives to latex, Tempurpedic, Sensus--which some people don't like specifically because of their temperture sensitve and slow recovery factors. My conclusion was that the memory foam toppers available from places like Bed & Bath & Beyond, Overstock.com or Mervyn's would probably be just fine, mainly because I have read posts from owners of Tempurpedic and Sensus products who have complained that they began sagging in a few years, so why pay a premium for it?

That's what I was considering to get for the latex mattress that I am putting together right now: http://cgi.ebay.com/ZIPPERED-VELOUR-COVER-for-8-KING-MEMORY-FOAM-MATTRESS_W0QQitemZ120153700910QQihZ002QQcategoryZ20479QQtcZphotoQQcmdZViewItem
It looks exactly like I am on our S. memory foam mattress from the store. And I know that it is flexible and it does not interfere with the latex feel. I am not so sure about the wool pad, being quilted and not flexible if it would not interfere with the softness of the mattress. I am considering adding one later, though.
I surely hope it will keep it together because the topper is sliding off the main core... Plus the kids started to pull the sheet out and punch and rip little pieces of the latex foam...it's a whole history!
