Hi Nabates1,
The information you need to make sure a mattress doesn’t have any weak links and to make more meaningful comparisons with other mattresses is in this article.
I would be very cautious about these two layers …
2.25" plush Spring Air Quilting Foam
3/8" Gel infused memory foam lumbar support
… because they are likely to be a weak link in the mattress in terms of durability.
For a mattress with only 2" of latex as well (and with the type and blend of the latex unknown) it wouldn’t be in the best “value” range for most people either.
I would also make sure you’ve read the mattress shopping tutorial here which has all the basic information, steps, and guidelines that you will need to make the best possible choices … and know how and why to avoid the worst ones.
