Hi Jewels,
It would depend on the specifics of the mattress. If you can provide the information about any of their mattresses you are considering that is listed in this article I’d be happy to make some comments about the quality of the materials. Without this information I wouldn’t have enough information to make any meaningful comments about any mattress regardless of the name of the manufacturer.
If you can find out the density of the layers from Jeff I’d certainly be happy to make some comments about the quality of the materials. Once you have this information you could also compare them to the guidelines here. Jeff is also an expert (and one of the members here) and is very knowledgeable about his and other mattresses and will also give you good information about the materials in all his mattresses.
