Hi Bruzer,
I would be very cautious about using other people’s experiences as a guideline because each person will have their own needs and preferences in terms of PPP and a mattress that is “perfect” for one person may be completely unsuitable for someone else to sleep on (see mattress firmness/comfort levels in post #2 here).
The best way to find out which types of mattresses you tend to prefer and that work best for you would be based on your own careful and objective testing using the testing guidelines that are linked in the mattress shopping tutorial.
There is also more about the many variables that can affect sleeping temperature in post #2 here that you can also use as a guideline as well.
Again I would treat the type of materials in your mattress as a personal preference issue rather than a “better worse” issue and I would use your testing to decide which type of mattresses you tend to do best with. Memory foam and latex are also very different “animals” and there is more about the differences between them in post #2 here. There is also more about the most important parts of the “value” of a mattress purchase in post #13 here but in most cases all the mattresses that are made by the same manufacturer would have a similar “commodity value” based on the cost of the materials and components inside them (although mattresses in a higher budget range will often have a little bit higher margins).
I believe that they closed their outlet store some time ago (see this post).
I’m looking forward to your feedback after your visit.
