Hi dchuck,
I don’t keep a record of the specs of individual mattresses at each store (that would be impossible for one person to keep up with) so you would need to call each of them with the specs you are looking for to see if any of them have anything similar in terms of the type of latex, layer thickness, ILD of each layer, and type of cover. There are so many latex mattress variations It may not be possible to find a close match or you may find some mattresses that are reasonable approximations but not the same.
The materials they use are good quality and they have a good comfort layer exchange policy and return policy so they would be well worth considering although I would also make some careful comparisons with other similar mattresses made by other manufacturers based on the parts of your own personal value equation that are most important to you. A forum search on Plushbeds (you can just click this) will also bring up more information and feedback about them.
The Boston list in post #2 here includes the factory direct manufacturers I’m aware of that are closest to you.
I’ve included a few of the more local retail possibilities in the Providence / Warwick region within about 35 miles or so that may be worth considering on a mattress by mattress basis. Make sure if you visit them that you call and check first to find out the specifics of what they currently carry and to make sure they will provide you with the specifics of the materials and layers in each mattress. The list includes the manufacturers they list on their site that I would consider but they will also require further research into their knowledge and transparency and to find out if their websites are up to date.
http://www.redstarmat.com/ is an upholstery shop in Cumberland, RI that carries some traditional two sided innerspring mattresses on her floor that are better quality/value. They can also make custom sizes for RV’s, boats, and trailers. Their mattresses are manufactured by Ecin Industries in Fall River so they can also order any of their other mattresses as well. They are upholsterers so they are familiar with and knowledgeable about foam quality and mattress materials.
http://www.mastersonupholstery.com/ Pawtucket, RI. Foam shop but carries Comfort Bedding mattresses. Very hesitant about disclosing foam densities (strangely enough) and I would avoid any mattress where you aren’t able to find out the type and quality of the materials inside it. Also has two sided basic innersprings.
http://www.jordans.com/ Warwick, RI. Carries their own Jordans brand along with Naturepedic and Pranasleep although some of these are in higher budget ranges than other similar mattresses so I would make some careful value comparisons here.
