Hi ademuzzy,
Welcome to the Mattress Forum! 
The best place to start your research is the mattress shopping tutorial here which includes all the basic information, steps, and guidelines that you will need to make the best possible choice … and perhaps more importantly know how and why to avoid the worst ones.
Two of the most important links in the tutorial that I would especially make sure you’ve read are post #2 here which has more about the different ways to choose a suitable mattress (either locally or online) that is the best “match” for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability, durability, and value.
[quote]Anyway I have been looking and tested the following:
Sleepeezee comfortm gel 3000 - cant find this on their website
Posturepedic ultimate latex - can’t find this on their website
Mammoth super soft medical grade foam(sounds like a trademark sales tactic) - never heard of them before
Posturepedic hybrid pocket ultima 2800 - seems a nice bed but not sure what geltex is?
Tempur Cloud platinum - very comfortable but very expensive and wasn’t that much better than the Posturepedic [/quote]
Outside of PPP (which is all about how well you will sleep on a mattress) … the most important part of the value of a mattress is it’s durability and a mattress is only as good as its construction and the quality and durability of the materials inside it (which is all about how long you will sleep well) regardless of the name of the manufacturer on the label.
I would avoid all the major brands (such as Simmons, Sealy, or Serta) or any other mattress that uses lower quality or “unknown” materials in the comfort layers especially which could be a weak link in the mattress in terms of durability (see the guidelines here). No matter how it may feel in a showroom … if you purchase a mattress that uses lower quality and less durable materials that would be a weak link in the mattress then they can soften or break down and you may need to replace the mattress much too quickly relative to the price you paid because the premature loss of the comfort and support which was the reason you purchased the mattress isn’t covered by mattress warranties (see post #174 here).
If you let me know your city or zip code I’d also be happy to let you know about the better options or possibilities I’m aware of in your area.
The mattress labels only specify the type of materials in a mattress but don’t provide any meaningful information about the design or the quality of the materials in the mattress so they aren’t particularly helpful when it comes to choosing a mattress.
You may need to reduce the size of your images to post them on the forum (see the help section here).
I’m looking forward to finding out what you end up deciding … and of course any comments or questions you may have along the way.
