Hi Jas,
I haven’t “analyzed” all the memory foam choices on the list but there is a small list of memory foam sources that I consider to be good quality and value in post #12 here. I would also give priority to any of these mattresses that disclosed all their layering (so you can make meaningful comparisons) or that were available locally (a local purchase can be less risky).
The guidelines that I use to compare mattresses are listed in post #10 here (one of which is CertiPur certification or as a minimum alternative North American poured foam) so once you know the layering and the quality specs of each mattress you are considering it becomes much easier to quality/value comparisons to another mattress. While this doesn’t say anything about the suitability of a particular mattress for your body type and sleeping positions or your preferences (there are many different types of memory foam that can each perform and feel differently) and also doesn’t take into account the ability of the retailer to help you make the best choice … it will at least provide a way to make more meaningful mattress comparisons.
Some of my thoughts about Novosbeds are in post #4 here but since that time they appear to have added the CertiPur certification to their site. They were apparently using Chinese memory foam from URE Plastics but it now appears that this is not the case. They were not so helpful when I last talked with them about the source or safety of their foam so its nice to see they’ve had a change of heart. I would consider them as a realistic option (and compare their mattresses, knowledge, and service to the other memory foam sources I listed) since they’ve at least “met” the criteria that are important to me and they also seem to have a good return policy.
