Hi twade,
I think that the poster you are replying to has already purchased a mattress and was just looking for some guidance about using the foundation that they built not about which types of mattresses work well with a platform bed.
This type of advice says very little because it’s much too generic and lacks specifics about what to look for or how to choose a mattress that is a good “match” in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) what to look for in terms of the quality and durability of the materials, or any of the other preferences that may be an important part of someone’s personal value equation.
I would also be very wary of suggesting that someone choose a mattress based on “showroom feel” or “comfort” which can often be very misleading and may not do a particularly good job of predicting how well someone will actually sleep on a mattress in “real life”. There is more about the most important parts of the “value” of a mattress purchase in post #13 here that can help consumers make more meaningful comparisons between mattresses in terms of suitability, durability, and “value”.
I would also be very cautious about using other people’s reviews or experiences on a mattress (either positive or negative) as a reliable source of information or guidance about how suitable a mattress may be for any particular person or the durability of a mattress and in many cases they can be more misleading than helpful because a mattress that would be a perfect choice for one person may be completely unsuitable for someone else to sleep on or vice versa (see post #13 here).
