This was very helpful. I will check to see if Dreamstar/Tor is using Certipur certified polyfoam in their hybrid. All the other options I’m looking at are 100% latex.
This right here is what it’s coming down to for me. I have talked to a few different sellers. One said no exchanges/refunds. Another said there would be a $100 fee and a limit of 7 days. I need to be working with someone who will at least be willing to try to get me into another mattress if the one I purchase isn’t working. I am willing to commit to buying from that seller - i.e. I am willing to waive the right to a refund. All I want is the ability to exchange if it really doesn’t feel right. Is 7 days enough to know? I’m not sure but that’s about the best I can do or so it seems right now.
Thanks again for all the good information.
