Hi thecountofzero,
Unfortunately the information you linked is incomplete and not detailed or specific enough to make any meaningful comments about either mattress.
Post #4 here describes the information you need to assess the quality/durability of the materials in a mattress and make more meaningful comparisons between them.
The good news is that Boston Bed is generally transparent about their materials and will probably provide them to you if you ask. If you can list the more detailed specifics of each mattress on the forum I’d be happy to make some comments or help you identify any obvious weak links in either mattress.
