Hi BKpcam1999,
Welcome to the Mattress Forum!
Nature’s Rest is made by Spring Air and it may be Spring Air’s bankruptcy you are referring to. Consolidated Bedding who owned Spring Air (and Nature’s Rest) went bankrupt in 2009 but it was quickly purchased by one of the original owners of Spring Air and re-launched soon after . Nature’s Rest was relaunched in 2010 .
You can read more about Pranasleep by doing a forum search on Prana. The good news is that they changed the design in their newer version 5 and the top layers of polyfoam are now higher quality/density and are no longer what I would consider to be a weak link in the mattress in terms of durability. Having said that they are still in a significantly higher budget range (as you mentioned) than other similar mattresses. There is more about the new version 5 in post #19 here but I would certainly make some very careful “value” comparisons with other latex mattresses that use similar materials and are in a much lower budget range before considering one of their mattresses to be the “best value” choice available to you.
Foam Sweet Foam is a member here, which means that I think highly of them, their products and their knowledge.
You can see some of my comments about Plushbeds in post #2 here. They generally use good quality and durable materials in their mattresses and they would certainly be a much “better than average” choice compared to most of the mainstream mattresses that most people end up buying. However, they do a lot of internet advertising so they do attract a lot of online attention with large “discounts”, so I would make some careful “value comparisons” with some of the other options that are available to you because they may not be in the “best value” range for many of the members here that are aware of the many other similar options that are available to them.
Another great online option would be the members of this site listed in post #21 here who are all very experienced and knowledgeable and specialize in providing the type of help and guidance on the phone that can help you make good choices. Many of these manufacturers offer latex component systems like what you are desiring, and I believe that all of them compete well with the best in the industry in terms of their quality, value, service, and transparency.
If you provide me your zip code, I can see if I am aware of any better brick and mortar retailers in your area.
I understand if you might find assembling a component system difficult or awkward, regardless of your age or ability. While it certainly can be accomplished by one person, I always recommend two people to make the task easier to perform. And ordering a product in a “split” configuration, even if you desire the same feel on each side of the mattress, can also make it easier when assembling a component system mattress.
It sounds like you are looking specifically for what is called “White Glove” delivery by the industry, where your mattress will be delivered and set up for you. Post #3 here, while not totally inclusive, includes a list of some online latex mattresses that have it available as of the last time I checked. I would also note that many manufacturers do have a White Glove option, but don’t list it on their web site, so you’d have to give them a phone call to see if it is available and how much extra it might cost.
