Hi mirpags,
There are some very good choices within about 60 miles or so of you but none that are really close. I believe it would be well worth your time to make a few calls though and then visit the ones that were most appealing to you (after asking about options, prices, types of latex mattresses etc). They would involve some driving time to Connecticut but in the end would save you a lot of time, money, and frustration overall.
comfortss.com/index.html Branford, CT. Local factory direct manufacturer which also makes a full range of high quality traditional innerspring, latex, and memory foam mattresses (including two side mattresses). They also have a custom zoned mattress which can be made in a side to side split design as well. They are also a member of this site which means I think highly of them and I believe they compete well with the best in the industry in terms of quality, value, and service. Post #17 here also has more about them and some of Nissanman’s posts include more feedback about their mattresses and their service.
