Hi Lnr103,
Hollandia used to be on the list but they don’t appear to be in business any longer in Philadelphia. They had some fairly interesting mattresses that were more European in design (with zoned layers that used different types of cutouts or surface modifications) but they were also quite pricey. Duxiana is in a much more premium price range and while they use good quality materials and have good designs, they would need to be significantly better than any of the other options you have available to justify their higher prices IMO.
Vita Talalay is made by Radium which are one of the two main manufacturers of Talalay latex in the western world (the other is Latex International). Like all Talalay latex they are a very high quality and durable material. I would treat the Talalay made by LI and by Radium as close equivalents.
[quote]I’ve made some notes in case we are steered in another direction: must have less than 1" low density polyfoam (meaning <1.8"), memory foam (meaning alb low density) or unknown foam.
With memory foam, thicker layers are not as good as thinner layers (<4" is better)
avoid all polyfoam in comfort layer (which is the top layer on the mattress).[/quote]
These are a little bit confused but close. If you are comfortable with polyfoam I would look for 1.8 lb density polyfoam or higher in a one sided mattress or 1.5 lb in a two sided mattress and no more than “an inch or so” of lower density (or unknown) materials in the comfort layers or quilting. Polyfoam can be a very good option in a lower budget mattress and I certainly wouldn’t avoid it for quality reasons in a suitable density. If you are comfortable with memory foam then the minimum guideline I would use for memory foam is 4 lbs or higher (again with the exception of "around an inch or so of lower quality materials in a mattress). It’s not so much that thicker layers of memory foam are “not as good” (for some people they may be fine) but that they can be “more risky” for some people because you may continue to sink in more deeply over the course of the night which can sometimes risk alignment.
I would tend to avoid overthinking all of this or “pre designing” your mattress and use your testing (backed up by making sure the materials are good quality) as your main consideration or as the best way to decide which type of mattresses you prefer.
This would depend entirely on which one was a good match for you in terms of PPP. The innerspring in a mattress is rarely the weak link of a mattress and any type of innerspring can make a good choice depending on the rest of the mattress design and the budget range. I never recommend specific mattresses (see mattress firmness/comfort levels in post #2 here) because it’s impossible for anyone to know which one is the best match for you based on specs or theory.
You should have many good options available for under $2200 yes but your choice would also depend on what you mean by “eco frendly” because this is one of those “marketing terms” that is used for almost everything in the industry and doesn’t really have a specific meaning and is mostly just “sales talk”. If you are looking for more “natural” materials for personal reasons then innersprings, 100% natural latex, and natural fibers are probably the most natural choices in terms of materials although I would also keep in mind that natural and eco friendly aren’t necessarily the same thing and if safety is your main concern then there are some synthetic or partly synthetic materials that may be just as “safe” as natural materials.
