Hi Rosey,
While other people’s comments about the knowledge and service of a particular business can certainly be very helpful, I would always keep in mind that you are the only one that can feel what you feel on a mattress and I would be cautious about about using anyone else’s suggestions, experiences or reviews on a specific mattress (either positive or negative) or review sites in general as a reliable source of information or guidance about how you will feel on the same mattress or how suitable or how durable a mattress may be for you and in many if not most cases they can be more misleading than helpful because a mattress that would be a perfect choice for one person or even a larger group of people may be completely unsuitable for someone else to sleep on (even if they are in a similar weight range). In other words … reviews in general won’t tell you much if anything about the suitability, quality, durability, or “value” of a mattress for any particular person (see post #13 here).
You can read more about Pranasleep in general and the previous versions (up to version 4) of Pranasleep mattresses in post #3 here and in post #2 here and in post #3 here and in posts #1 and #2 here and a forum search on Prana (you can just click this) will also bring up more information and feedback about them as well.
The good news is that they changed the design in 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 than other similar mattresses and the top layers are still polyfoam so you would still be feeling and sleeping on polyfoam as much as latex but this could also be a “feel” that you prefer compared to sleeping more directly on latex . 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.
I would also treat the purchase of an adjustable bed and a mattress as two separate purchases so you can decide which one of each you prefer and make apples to apples comparisons with each of them instead of being locked in to a combination where you may prefer either the mattress or the adjustable but not both (unless of course you would purchase the same mattress and adjustable from the same source if you were buying them separately anyway or you are receiving a discount for buying both that would make purchasing the combination purchase worthwhile for you). If a mattress works well on one adjustable bed then the same mattress will “work” just as well on any adjustable bed.
There is more information about choosing an adjustable bed in post #3 here and the main adjustable bed topic that it links to that can help you choose an adjustable bed based on price vs features comparisons and also includes some retailers that you can use as good sources of information about the features of the adjustable beds they carry and as pricing references as well (in post #6 in the main adjustable bed topic). Of course there are many other sources as well and prices can change on a regular basis so I would also include some internet searching in your research. I would also keep in mind that online advertised prices are often price controlled so make sure you call the stores you are considering to find out their best prices rather than just looking at websites.
Subject to confirming that any retailer or manufacturer on the list is completely transparent (see this article) and to making sure that any mattress you are considering meets the quality/value guidelines here … the better options or possibilities I’m aware of in and around the Atlanta, GA area are listed in post #2 here.
