Does a memory foam mattress need to be replaces faster than a spring mattress? Or is it just the same minus the metal?
I am not an expert, nor have I worked in the industry. Ever. All that follows is what I learned when shopping for my first latex mattress.
First, I want to clarify what a foam mattress is: latex. However, every day common latex it is not. This type of latex is a chemically PATENTED kind of latex. It is a "closed cell" type of latex. And this latex is a patented chemical compound. Thus, ALL LATEX FOAM MATTRESSES ARE NOT THE SAME! Patents make them different.
I cannot comment on the mattress Wooted; I don't know it's maker. I personally own THREE (3!) Tempur-Pedic king-size mattresses. None of them require: (1) turning; or (2) being "ditched" every 8 years. Why? 1. Because they never get 'worn-in'; and, 2. because sweat, dead skin cells and 'other factors' do not collect on the mattress (when the factory-provided cover of the mattress is treated as required by the owner's manual).
All 3 of my king mattresses came with a cheese-cloth-like cover over the mattress itself, and a removable and washable mattress cover that is to be periodically removed and washed according to the instructions provided. I'd suggest a sweaty person (such as myself) wash the cover more frequently than a less sweaty person (I wash my cover about every 2-4 months in the summer/fall, and every 3-6 months in the winter/spring). Washing removes dust mites and skin cells, as well as any sweat that soaks through bed sheets into the cover. The goal is to prevent sweat soak-through to the mattress. The mattress maker does not recommend using an additional mattress cover. I don't.
As to wearing-in (that is, making trenches in the mattress where bodies lay sleeping), traditional mattresses require turning because of spring break-in/loss of tension and padding compaction. Memory foam mattresses have neither springs nor padding. Therefor, turning foam yields only back injuries and disdain for the mattress. Turning a foam mattress is much like flipping Jell-O. Go with the odds-makers and bet against turning your foam mattress. Just say NO!
Humor aside, with no springs to wear out or padding to crush, foam does not yield trenching. The resilience of foam, logically, wears down or out, whatever is the term or process, right? Well, yes and no. Open cell foam, like a sponge, allows air to escape from within its "honeycomb" structure when compressed. All of the air once inside the sponge may not return to fill all of the spaces it did before being compressed. As compressions occur, resilience is lost -- trenches are formed in open-cell foam. Many foam mattresses are made with cheap latex that loses resilience over time -- trenches form. A quality latex mattress is made with CLOSED CELL technology. There is a big difference!
