Hi MelissaRz,
Like you I hope Bob manages to bring his business back and I know he has plans in the works but they have not yet happened.
The members here who sell latex mattresses online in various types and designs are listed in post #21 here. Several of these sell various types of components designs where you can choose your own layers or even split the layers. As GW208 mentioned … Flobeds also offers a custom zoning option with their vZone mattress although it’s different from the CSD zoning design.
They would certainly give you the chance to test the overall “feel” of talalay in the designs they offer although they would be different from other designs in terms of performance and how well they matched your needs and preferences in terms of PPP. A forum search on hcmattress (you can just click this) will bring up more about them.
Pure Latex Bliss also makes all Talalay latex mattresses in several designs (mostly blended Talalay) and you can find the nearest store that sells them in their retail store finder here.
Again bear in mind that every difference in design will result in a different feel and performance even if the material itself is the same but testing several different designs can give you a general sense of which mattresses you tend to do best with (firmer/softer in the deeper layers and firmer/softer in the upper layers etc).
You can read a little more in post #14 here about the potential benefits of a thicker mattress and post #2 here has more about the benefits of having more layers in the mattress (can provide more options but can also be more complex and may not be needed).
Post #2 here has links to some of the theory about how to design for different body types and sleeping styles but these are only generic and don’t apply to any specific person. The best and simplest way to choose a design is either based on your own personal testing for PPP (Posture and alignment, Pressure relief, and Personal preferences) or with more detailed conversations with a manufacturer that you are considering. There are too many unknowns and variables for “theory at a distance” to be an effective way to make a choice.
Some of the better options or possibilities I’m aware of in the Long Island area are listed in post #4 here but you will need to call them to find out what they have available in their showroom and make sure they carry the types of mattresses you want to test.
The better options in the New York region are listed in post #2 here and there is a more categorized list with more complete descriptions of some of them in the northern NJ list in post #7 here.
