Final Components: Topper and Cover

Hi ryanneedsabed,

I got tired just reading about your fitness activities. You’re certainly more dedicated than I am :slight_smile:

Latex International is no longer making Talalay GL slow response so it’s not likely that you will be able to order it unless someone still has some old stock remaining. It just wasn’t popular enough for Latex International to continue making it because people that preferred a slow response material generally tended to choose memory foam and those that like the feel and resilience of latex tend to avoid slow response materials. If you can’t find any Talalay GL slow response then it may be worthwhile checking with Ken at Arizona Premium because he may have access to some slow response Dunlop that is made by Latexco.

There would be little difference between 19 ILD and 21 ILD. ILD differences less than about 4 would be less than most people would notice and a difference of 2 ILD is less than the normal ILD variation across the surface of a layer anyway (see here for an example of the differences between 9 measurements in different parts of a core).

The temperature difference in Talalay GL would generally be “slight” (see post #2 here) and may be a less significant part of how warm or cool your mattress sleeps than the type of cover, mattress protector, or sheets and bedding you use.

If you are working on a DIY mattress then I would start by reading option 3 in post #15 here so that you have more realistic expectations of success with your initial layering and the trial and error and learning curve and in some cases the additional expense that can be involved in a DIY mattress. My choices would likely be very different from someone else but if you aren’t working on a specific design as a target that you have tested and are confident is a good match for you in terms of PPP and you are uncertain about the layering that will work well for you then I would use a “bottom up” approach where you can use your actual sleeping experience on a particular layer or combination to help you decide on the next “piece of the puzzle” to add on top. As long as any of the combinations aren’t too soft then you would have “room” to add an additional layer until you are down to very small “fine tuning” choices.

The type of cover would be strictly a preference choice. There is more about wool quilted covers vs a stretch knit cover in post #6 here and there is more about quilted covers in general in post #12 here and the posts it links to. The components post here includes the better sources for mattress components including covers that I’m aware of and if you decide on a stretch knit cover then post #4 here includes the sources I’m aware of that carry them.
