Hi terminaldawn,
This is an online outlet for Boyd Specialty Sleep.
They use CertiPur certified foams (you can see the email exchange I had with them in post #5 here) but I would still want to know the quality/density of the materials they use (all the memory foam layers and the polyfoam layers) so you can determine the quality of their mattresses (they only list some of them). A forum search on Boyd will bring more information about them.
So with the caution that the density of the layers is the only way to know the quality and make meaningful comparisons with other mattresses … and if you are OK with materials that are sourced in China … they may be worth further research to see if you can ask the questions and get the answers you would need to make meaningful comparisons and a good decision.
Just FYI … post #12 here lists a few of the better online memory foam options.
