Taped edge vs zipper?
I looked at a pure LatexBliss Beautiful and the tapped cover actually had a rise/rounding to it. I had mentioned a rigid poly foam border on my current S&F and I guess i was expecting that with latex zippered covers that the sides of the cover would be inherently more rigid. Now I did notice that the location of the zipper differs between the online retailers. Some are located at the top edge (ex, Sleep EZ) and others are located about half way up the side (Flobeds?).
The Beautiful doesn't have a tape edge and the cover is removable. The sides of any cover wouldn't be "stiff" like the rigid polyfoam in the S&F but I don't think any of the covers you are mentioning would have an issue with becoming loose or wrinkled over time (possibly the Bliss more than the other two because they are a stretch material and aren't quilted).
Plus...doesn't it get kind of gross in there after awhile? Even with a cover it seems like sweat and skin flakes would accumulate over time, and there's no way to really clean the latex (right?)
I'm just wondering how this works out in real life...I like the idea but wonder if it's something I'd really use. In my case, my bed would be softer, so I guess the layers might break down faster, but I'm also 135, so not sure I'm stressing them as much.
I could also see spilling something on the cover and needing to wash it, although I never take liquid anywhere near my bed except water.
Toppers are added to a new mattress for a variety of reasons; changing needs of sleepers, aging, softening a guest room mattress, and also prolonging the life of a mattress. I have seen some consulting data, that shows the millions and millions of topper units sold through Costco, Bedbath Beyond, WalMart, Target, etc etc. The specific reasons people purchase and how many fall in each category is relatively unknown.
Adding a layer to an existing mattress within a zipper cover is really a small niche of people, but on the TMU we hear from many of these people because some of our more loyal members have specialized in this.
Any bedding, including pillows, can get kind of gross after a while from sweat, skin, dust mites, etc., If the cover is a zipper cover, most of these can be washed, and latex can be washed by hand and air dried, but very few people ever do this. Also, most people put the layer/topper under a mattress pad, so it is protected somewhat.
I have a spare topper that's been out unprotected for three weeks while I've been messing with my build, and would potentially want to wash it before putting it into a mattress bag for long term storage.
Do I need to use distilled water - I would imagine the mineral deposits and chlorine from tap water would be a no no?
For that matter, is there any truth to latex failing from "drying out" and if so what could someone do to prevent this.
Regarding washing latex I will refer to a couple of things. The law tag for the Talalay latex pillows, which consumers generally ask about more often than topper/mattress, here is one version of wash/care instructions I found:
"This pillow is made of a sterile hygienic material that does not require washing. It can be spot cleaned with warm water and mild soap. Rinse with warm water and dry thoroughly at room temperature away from heat and light. Never place in a machine washer or dryer."
I personally do not have any information about distilled water, my instinct says that this is not a big deal, as its used for wiping, and then air dry, cant see a light cleaning with minimal chlorine would make a huge difference.
Most data of "latex failing" from what some people may refer to as "drying out" would be from Thermal Oxidative Degradation of Rubber..... I dont actually know what that means I just wanted to write it to sound smart....just kidding...rubber exposed to heat, light and oxygen. I do sometimes refer to the polymer websites for my rubber chemical stuff... polymer database link here.
Again just letting you know message received, you have the general best practice for latex foam...out of sunlight, but also out of direct home UV lights, not just sunlight. Again thank you for your participation in these forums.
