Hi xpnsvtoys,
Clawdia has already suggested a forum search on Savvy Rest (you can just click this) which will provide much more information and feedback about your mattress.
What I can tell you is that your mattress uses very high quality and durable materials and components (natural or organic latex and an organic wool quilted cotton cover) and the design of your mattress (individual components that can be re-arranged or exchanged after a purchase to fine tune the mattress to your specific needs and preferences) is also very flexible and gives you good options both before and after a purchase. As you mentioned … the suitability of a mattress in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) is one of the most important parts if not the most important part of a mattress purchase and your personal value equation.
You have hopefully also tested the specific mattress you purchased in the specific combination of layers and type of latex you chose and as long as your testing was careful and objective then your odds are higher that you made a suitable choice than choosing a mattress that you haven’t tested in person. Every difference in a mattress can affect the feel and performance of a mattress and while the SleepEz mattresses are also very high quality and they are great “value” … they may not be exactly the same even though the design and materials are very similar.
Years down the road you will remember much more about how well you slept on the mattress and how long it lasted than you will about how much you paid for it although of course the initial cost is also an important consideration in any mattress purchase.
Only you can decide on what you “should” do based on your own “best judgement” and it may not be possible to cancel your purchase (you would need to call the retailer to find out) but if your primary considerations are the quality of your mattress and the materials and components that it uses and the flexibility to make changes after a purchase then you certainly made a better choice than the large majority of consumers make with a mainstream mattress purchase … even if there are other similar mattresses that would cost you less.
