Hi Grateful,
As you can see in my comments at the end of post #13 here … I also think highly of Gardner Mattress.
If you plan to be in Massachusetts or Boston region anyway then post #2 here may also be helpful.
My Green Mattress is one of the manufacturing members of this site which means I also think very highly of them and they compete well with the best in the industry in terms of quality, value, and service.
