Hi GW208,
The urban Sleep Store carries OMI, Pure Latex Bliss, Technogel, and Tempurpedic according to their site and all of these use good quality materials (Tempurpedic for the most part but not in their Tempur - Choice line). Tempurpedic is poor value compared to other similar mattresses. OMI generally carry premium prices compared to other similar latex mattresses and they carry a fairly significant “organic” premium. The Technogel mattresses are also very costly (a forum search on Technogel will bring up much more comments and feedback about them).
Pure Latex Bliss is owned by Latex International who makes the Talalay latex used by many manufacturers and is also uses high quality materials but are also not always in the “best value range”. They have been quite popular and a topic of frequent discussion on this site. They have MAP pricing (minimum advertised pricing) so there is a wide range of “real” prices that various retailers charge throughout the country so I would make some careful comparisons.
Overall Urban Sleep Store would certainly be a good place to test some high quality latex mattresses but I would make sure you make some careful value comparisons to other similar mattresses (or with other retailers) based on your personal value equation.
