Hi Bedseeker,
The first place to start your research is the tutorial post here which has all the basic information, steps, and guidelines that can help you make the best possible choices, know how and why to avoid the worst ones, and make more meaningful comparisons between mattresses.
Yes … the tutorial post includes a link to some of the members here that sell latex mattresses online that include many different features, options, and in a wide range of budgets that would be well worth considering if you are looking at online latex mattresses.
A forum search on Plushbeds (you can just click this) will bring up more comments and feedback about them. They certainly use good quality materials with no weak links in their construction and would be a “better than average” choice compared to most mainstream options but I would make some very careful value comparisons with some of the other options you have available here that use the same or similar materials and offer more options and/or lower prices and don’t spend as much on online advertising.
Each company that offers component mattresses has their own exchange policy which may be even more important than a return policy for people who know they like latex and only need to fine tune their mattress rather than return. They also have a good return policy and I certainly agree that it’s a good idea to factor both of these into the “value” of the mattress purchase as of the important parts of each person’s personal value equation. They are certainly not alone in having good exchange and/or return policies. I should also mention that while it can be costly to return a whole mattress with a common carrier (they are too large to ship with courier), component mattresses that can be shipped through courier are much less costly to ship.
This depends entirely on what you mean by “a truly organic mattress” since this is probably more of a marketing term than anything else. There is more about organic Dunlop latex in post #6 here and more about organic certifications in post #2 here and post #2 here that may help you decide if an organic latex certification or which level or organic certification may be worth the extra cost to you. Some of their mattresses include GOLS certified organic Dunlop but there isn’t any certified organic Talalay and their mattress isn’t made in an organic factory so it would be more accurate to say that some of their mattresses include some organic components.
Warranties are also mostly about marketing and have very little to do with the useful life of a mattress or how long you will sleep well on it before you need to replace it. Warranties only cover manufacturing defects which will generally happen very early in the life of a mattress … not the gradual (or sometimes rapid) loss of comfort and support that will be the most likely reason you will need to replace any mattress. There is more about warranties in post #174 here but I would pay much more attention to the type and quality of the materials in a mattress than the length of a warranty.
While all foam materials will soften or impress to some degree over time but latex is the most durable of all the foam materials and will do so less and over a longer period of time than other types of foam materials such as memory foam or polyfoam (even if they are good quality) There is more about all the factors that can affect the durability and useful life of a mattress in post #4 here and the other posts it links to. There is also more about the different types and blends of latex in this article and in post #6 here.
There are too many unknowns, variables, and personal preferences involved in terms of PPP for me (or anyone) to use only specs (yours or the mattress) or “theory at a distance” to choose a mattress for someone else (see mattress firmness/comfort levels in post #2 here). When you can’t test a mattress in person for PPP then the best source of guidance would be more detailed phone conversations with the online retailer or manufacturer you are working with who know more about their mattresses, the options they have available, and which ones are likely to be the best “match” for different people based on “averages” than anyone else.
All the layers and components of a mattress including the comfort layers, any transition layers, and the support layers are an important part of choosing a mattress that is the best match for you in terms of PPP yes.
There may also be some local options available to you as well and if you let me know your city or zip code I’d be happy to let you know of the better options or possibilities I’m aware of in your area. Either way … you have some very good options to choose from.
