Hi cprice88,
Thanks for all the updates on the Austin list … I appreciate it 
One of the forum members here visited them in Austin in late December and they were still open (see here) so it must have been very recent. They are also no longer listed on the Clean Bedroom site and I’ve removed them from the Austin list.
they still list Restonic which would be a good “possibility” … just not their latex models.
They didn’t have a local store at all after the ownership changed (see post #29 here). Have they re-opened a local store in Austin now (just not with latex)? If you can confirm this I’ll update the description on the Austin list to mention that at least some of their mattresses are once again available to test locally.
I’ve updated their listing as well including their non latex options.
Any type or blend of latex would be a good quality and durable material relative to other types of foam materials and any mattress that is “all latex” wouldn’t have any weak links in terms of durability.
Pure Latex Bliss mattresses have MAP pricing (minimum advertised pricing) and there are some dealers that sell them for this but dealers are allowed to sell for less as long as they don’t advertise it and they are certainly available for less than their suggested retail prices. If you do decide on one of their mattresses there are some PLB dealers that will ship across the country listed in post #32 here that you can call to use as a pricing reference point for any “negotiation” and I would start by giving Jeff a call at Matt-To-Go who is one of the members of this site.
You are certainly looking at some good options and when your final choices are “tough” and there are no clear winners between them then it usually means that you’ve done some very good research
