Hi Pierce,
The better options or possibilities I’m aware of in and around the Washington, DC area (which has some overlap with the Baltimore list) are listed in post #2 here.
The specs you listed are probably from the law tag and don’t provide any meaningful information about the the type or quality of all the materials and layers in the mattress.
If you can find out the information listed in this article and post it on the forum I’d be happy to make some comments about the quality and durability of the materials inside the Juliet but unfortunately it’s not likely that you will be able to find out the information you need either from Kingsdown or from your retailer (see here). If a retailer or manufacturer either can’t or won’t provide this information then it’s not possible to make any meaningful comments about the quality or durability of any mattress or make an informed choice and I would pass the mattress by.
