Hi snl42,
I added one more option to my earlier reply, the M+K. I also found the Pure Posture. There are quite a few more listed in a google search here. But most are not available in the USA.
I’m not sure what size you are considering, but many of the site members listed here in post #21 offer component latex mattress systems, and they allow you to choose a mix of Dunlop and Talalay, they have great return/exchange policies, and their pricing is very affordable. They are all very experienced and knowledgeable and specialize in providing the type of help and guidance on the phone that can help you make good choices. There are a wide range of latex options included in the choices there and I believe that all of them compete well with the best in the industry in terms of their quality, value, service, and transparency.
I understand. Only you can determine what is part of your personal value equation, and the weight to give to each item on that list.
