Hi NeedABedASAP14,
Unfortunately (or fortunately depending on your perspective) final choices are something that only you can decide based on the parts of your personal value equation that are most important to you. Just like ordering a good meal at a restaurant … you are the best judge about which of the preferences or options that each manufacturer provides are most attractive to you. You really are choosing between “good and good” and helping you reach that point where there are no “bad” options is the goal of the site but past that it’s really up to you.
Post #21 here includes the members of this site that sell latex mattresses online.
I would keep in mind that a latex mattress will be nothing like any of the Tempurpedic mattresses and it may be a good idea to test some latex mattresses locally to make sure that latex really is your preference over memory foam (you can read more about how they compare in post #2 here). Both can make good choices as long as they use good quality materials. If you let me know your city or zip code I’d be happy to let you know of any of the better options or possibilities I’m aware of in your area so you can have some reference points based on personal experience that may help you decide.
