Hi msalerno,
The description you linked on their website has most of the specifications that you need (see here). You can see some general comments about Golden in post #2 here and the 6" Reflections mattress has 6" of 100% natural Dunlop latex over an 8" polyfoam support core (see posts #4 and #5 here) and there are no lower quality materials or weak links in the mattress. Depending on the retailer that sells it and assuming that it’s a good match for you in terms of PPP … it would typically be in a relatively good “value” range.
