Hi davo32683,
The Arizona Premium Ultimate Hybrid uses a Leggett and Platt Quantum pocketed coil innerspring unit, above which is 3" of latex. You can choose between firm, medium and plush, and either natural Dunlop or natural Talalay. The covering is a zippered bamboo/wool stretch knit. There is a 60 day trial period.
The closest Luma mattress to the Ultimate hybrid would be their Latex Hybrid Slumber System. This uses a pocketed spring unit with a 1" base of polyfoam (1.8 Lb High Density). On top of this spring unit is 1.5" of blended Talalay latex. The cover is a tencel stretch knit. On top of this is a separate topper called their Talalay Latex Comfort layer that is 3" of blended Talalay. Mattress comfort choices can be made in plush, medium firm, or firm. There is a one year comfort/return period.
Both of these mattresses use good quality materials and there would be no “weak links” in their construction. I think highly of both of these companies, and Arizona Premium is a member here of the site.
Every mattress purchase though includes more than just the “material value” of the mattress and all the many tradeoffs involved in the mattress itself as well as all the other options and services that are part of every mattress purchase are all part of what I call your “personal value equation” . There is also more about the most important parts of the “value” of a mattress purchase in post #13 here but in the end everyone will need to decide what is most important to them and attach a “value” to all the objective, subjective, and intangible factors that are part of any final decision. There is no “best and worst” any longer at this point … only best for YOU. In terms of quality and value there are really no “bad choices” or “mistakes” here and there are no clear winners between your finalists, so the odds are higher that any one of them would be a good choice that you would be happy with.
