Not surprisingly considering their knowledge and experience … you are being given accurate information all around.
You can read more about the differences between 100% natural Talalay and blended Talalay in post #2 here. As they indicated … most people who order 100% natural do so because they prefer a more natural product for personal reasons … not because it is a better or “safer” material.
Again he is correct that with a suitable cover you won’t feel the split in the layers. There is more about split layers in post #2 here.
I don’t have any personal experience with their specific protectors but you can read more about the pros and cons of different types of protectors in post #89 here. If the one you are looking at is this one then it is one of the membrane type of protectors that will work well for most people that are looking for waterproof protection and that has little effect on the “feel” of the mattress.
Once again they are right that most people at your weights wouldn’t “need” a latex mattress that was thicker than 9" although some people may still prefer it. There is more about the pros and cons of a thicker latex mattress in post #14 here and more about the pros and cons of having more layers in post #2 here.
There is no problem mentioning names and you were probably talking with either Shawn or Jeremy … both of whom are very knowledgeable and experienced and provide great information and guidance to their customers. As you probably know from your reading on the site … there are many members that have been very happy with their purchase from SleepEZ and they are certainly a great quality/value choice. These types of savings compared to more mainstream manufacturers are the “norm” for the members here that have learned how and where to shop for a mattress
