Hi Geekymom1,
As you know the mattress shopping tutorial includes a link to a list of the members here that sell mattresses online (in the optional online step) that all compete well with the best in the industry in terms of their quality, value, service, transparency, and knowledge and many of them sell latex and latex hybrid mattresses that use different types and blends of latex that have a wide range of different designs, options, features, return and exchange policies, and prices that that would be well worth considering.
Unfortunately I don’t know their manufacturing and shipping times off the top of my head so you would need to call them to find out how long it would take each of them to ship a mattress to your location.
