Hi austinsoul2012,
I’m a little confused why you are looking at the uncertainty of an online purchase (especially when it may end up the same as your experience in the stores) when there is such good value available locally. For example at Sleepworld, the 7" blended Dunlop mattress is similar to the one you are looking at (although it is blended Dunlop not natural) and could probably be chosen in a firm ILD and it is $699 for a twin XL set. The 9" talalay could probably also be made in a firm configuration is $1299 for the set and there are others as well. These are all better value than what you are looking at so I’m thinking I must be missing something.
If you are looking for an an online mattress purchase though for whatever reason, then my recommendations are in post #21 here which has a list of the members of the site which, specialize in working with their customers over the phone, and have some of the best online mattress values in the country. There are a wide range of latex choices here but there is also better value here than what you are looking at.
Although Olejo has some very good value in adjustable beds and some of their mattresses have above average value as well (including the Eclipse that you mentioned) … they are not in the same value range for mattresses as what you will find locally or from members of the site. Some of these also offer layer exchanges (where you can exchange a layer of a multiple layer mattress to make adjustments after a purchase if it’s needed).
If I was in your shoes I would be speaking with the two outlets you have talked with locally and find your best choice between them because they would have pretty much anything in latex you could buy at Olejo and probably better value but if you are looking to purchase online then I would look at the outlets that are in the list.
