Hi ttran,
I would have a hard time imagining a worse way to choose a mattress than going by other people’s “votes” or based on the reviews and experiences of other people whose needs and preferences or experiences may be very different from your own (see post #13 here). This would be a lot like choosing the food you ate or the clothes or shoes you buy based on other people’s “votes” that may have little knowledge about you or your circumstances, the options you are considering, and may have very different tastes, sizes, or preferences than your own
Even if some of the members here have purchased one of the mattresses you are considering … they would probably have little knowledge or experience with any of the others and a mattress that is “perfect” for one person may be completely unsuitable for someone else to sleep on because of differences in body types, sleeping positions, sensitivity, physiology, or preferences.
If you follow the steps in the tutorial post one by one along with the suggestions in my reply here in your other topic you will have a much higher chance of success than asking others to “vote” on your choices.
