Hi Littlehouse,
Probably not 
The first place to start your research is the mattress shopping tutorial here which includes all the basic information, steps, and guidelines that can help you make the best possible choice … and perhaps more importantly know how and why to avoid the worst ones.
Two of the most important links in the tutorial that I would especially make sure you’ve read are post #2 here which has more about the different ways to choose a suitable mattress (either locally or online) that is the best “match” for you in terms of “comfort” and PPP (Posture and alignment, Pressure relief, and Personal preferences) that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists (based on all the parts of your personal value equation that are most important to you).
I would keep in mind that Foam Sweet Foam no longer has a local showroom where you can test their mattresses in person and they are only sold online.
If you are looking at online mattresses then the tutorial includes a link to a list of the members here that sell component mattresses online and many of them (including SleepEZ and Foam Sweet Foam) sell mattresses that have a similar design and use the same or very similar materials, components, and types and blends of latex as the Savvy Rest mattresses. There is more about how Savvy Rest compares to SleepEz in post #4 here and a forum search on Savvy Rest SleepEZ (you can just click the link) will bring up all the forum posts that mention both of them as well.
Foam Sweet Foam provides a choice between certified organic Dunlop and 100% natural Talalay similar to Savvy Rest as well (the Dunlop in SleepEZ mattresses is 100% natural but isn’t certified organic like Foam Sweet foam or Savvy Rest).
There is also a list that includes many of the component latex mattresses that are available online in post #3 here that may be helpful and if you let me know your city or zip code I’d be happy to let you know about any of the better options or possibilities I’m aware of in your area as well.
I would always keep in mind that the only reliable way to know for certain whether any mattress or combination of materials will be a good “match” for you in terms of “feel”, “comfort”, firmness, and PPP will be based on your own careful testing or personal experience but when you can’t test a mattress in person then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help “talk you through” the specifics of their mattresses and the properties and “feel” of the materials they are using (fast or slow response, resilience, firmness etc) and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked or other mattresses you are considering that they are familiar with, and the “averages” of other customers that are similar to you. They will also know more about “matching” their specific mattress designs and firmness levels to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with such as Savvy Rest) than anyone else.
