I am about a week into sleeping on the Ravelli and IMO it does a good job matching the grandbed in feel, as advertised. I tested all of the Tempurpedic line in the stores, so I have a pretty good reference point. So I would trust what they have written on the site for comparable models.
So far my impression is good. It feels like it is high quality, it does not have bad off-gasing, and the purchase experience was good.
I was going to update my own thread, but I was waiting on some additional construction information from them. That is my one disappointment, on the phone they were not able to get very detailed, so I sent an e-mail a couple weeks ago. I got a response saying it was “sent to management” and have followed up multiple times with no reply. Supposedly the customer service are “mattress experts”, yet are unable to handle a pretty simple request on their own and need to consult management?
Anyway, they come with a label with the construction materials. That led to my second gripe, as in the absence of any response decided to review it. I am no expert, but the thicknesses do not appear to match the website description in both the totals and potentially the materials.

This is the best I was able to determine regarding their thicknesses and purpose, though I don’t know it the exact order is discernible:
Comfort layer:
2 x 1" (Blue Gel" (guessing it is a gel memory foam)
1 x .9375" (TG Adaptaflex memory foam, guessing another gel formulation?)
1 x 2.68" (TG Adaptaflex memory foam, guessing another gel formulation?)
Total of 5.6175 inches, 6" on the website. But the website shows a 3" & 2" (same materials) and a 1" layer in-between (different material), but looking at the label I can’t seem to make it match their advertised construction, even if pieces were glued. The label shows ~2" and ~4" of materials, not 5" and 1" as the website shows.
Support:
1 x 5.75" (Crushed, guessing that is the thicker layer of poly-foam)
1 x .9375" (FE, guessing this is the firmer poly-foam)
1 x 1.875 (FE’ guessing this is the firmer poly-foam)
Total of 8.56 inches, 9" on the website, but the materials/proportions seem more consistent with what is advertised.
Total mattress: 14.1775 (this matched my actual measurement on the bed, slightly over 14")
On the website the layers add up to 15". Overall the upper portion doesn’t really seem to match the description exactly, but it is hard to tell since they use a proprietary naming system and everything is “cool touch” or “cool logic” etc. When I looked up Adaptaflex (http://flexiblefoam.com/), there is quite a variety of options they sell, and I assume they make custom blends, I don’t know if much can be gleamed from the tag on the actual material qualities.
Overall I am happy with it. But I think their website and customer service knowledge/accuracy is a bit lacking. Their use of special names and rounding up of thicknesses is a bit misleading and my gut feeling is that the pictures shown may be different than the actual construction, it seems close, but off.
