Hi jsuehl,
Hopefully Lackofzzz will see your post and share their comments but 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 other people’s experiences or reviews on a mattress (either positive or negative) or review sites in general (with or without videos) 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 most consumers have little knowledge about mattresses and mattress materials or how to assess the quality of the materials in a mattress and any 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 certainly 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).
As you know the Flobeds vZone mattress is great quality component mattress and you have many options available to customize the layering and zoning after a purchase. I would call them on the phone to discuss your situation and any “symptoms” you are experiencing so that they can make some suggestions and provide some guidance about how to customize your mattress so that the combination of layers and zones will be a better “match” for you in terms of PPP (Posture and alignment, Pressure relief, and your Personal preferences).
All the major brands (such as Sealy/Stearns & Foster, Simmons, and Serta) tend to use lower quality materials in their mattresses than most of their smaller competitors that will tend to soften or break down prematurely relative to the price you pay and I would generally suggest avoiding all of them completely (and the major retailers that focus on them) along with any mattress where you aren’t able to find out the type and quality/durability of the materials inside it (see the guidelines here along with post #3 here and post #12 here and post #404 here).
Buying a mattress that uses lower quality and/or “unknown” materials would be a very risky purchase and would have a very high chance of buyers remorse much too quickly after a purchase.
