Hi kyle1125,
The number of layers in a mattress is not a particularly meaningful spec so I would completely disregard this.
The most important layers in a mattress are the comfort layers and the Boyd uses less memory foam and overall the quality/density of the memory foam is less than the Ultimate Dreams (it only uses 4 lb memory foam while the Ultimate Dreams uses a combination of 4 and 5 lb memory foams).
I would also be aware that the “engineered latex” in the Boyd mattresses are not latex at all but polyfoam. Their use of this terminology is completely misleading IMO and is one of the cautions I have mentioned about Boyd in many forum posts. There is no latex in this mattress and you would need to know the density of the polyfoam to make an informed purchase decision.
Boyd memory foam mattresses are Level 1 certified by the Specialty Sleep Association but the criteria they list for Level 1 here says that Level 1 includes CertiPur certification which is different from the criteria on the Specialty Sleep Association site here which doesn’t mention anything about CertiPur certification for Level 1) and unlike Dreamfoam they are not not listed on the CertiPur site here* as a manufacturer so it’s unclear to me if their polyfoam and memory foam is CertiPur certified.

Dreamfoam mentions and feedback seems to confirm (for the most part) that their 13" gel memory foam mattress is similar in terms of its softness level to the Tempurpedic Luxe except perhaps a little firmer. Boyd doesn’t make any comparisons at all to the Tempurpedic line and since I haven’t tried either mattress and have no personal experience with either of them I really don’t know.
Your own personal testing or experience is the only way to know this (see mattress firmness/comfort levels in post #2 here). Theory at a distance is not an effective way to know which mattress is the best “match” for anyone in terms of PPP or any particular back issues but if you are prone to back pain then good alignment on a mattress is particularly important and I would tend to be cautious with mattresses that are too soft. If you aren’t able to test a mattress in person then the return policy of the retailer or manufacturer may become a more important part of your personal value equation.
