Hi nancymariec,
The bottom layer of the mattress seems to be unusually soft for a support layer (22 ILD is in a softer range) and could affect support/alignment when you are sleeping on the mattress over the course of the night but this is a comfort/support issue not a quality issue so I would make sure that you have done some careful testing on the mattress and confirmed that it’s a good match for you in terms of PPP.
In terms of the quality of the materials … the top 3" or so would be fine (about an inch of unknown materials in the quilting and then 2" of latex which would be a good quality and durable material).
Under this is 3" of 1.65 lb polyfoam which is a little on the low side (I would normally suggest 1.8 lbs as a guideline for a one sided mattress) but if you aren’t in a higher than average weight range where you are compressing the mattress more deeply than those that are in lower weight ranges and since it’s under 2" of a higher quality and more durable material which would take up most of the compression forces and is close to the guidelines I would suggest then it should be fine and and would be “in the range” where there wouldn’t be any significant or obvious weak links in the mattress.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here but “value” is always relative to the other mattresses that are available to you and that you are including in your list of finalists. It would also depend on the size of the mattress (larger sizes cost more), on whether this is a “mattress only” purchase or includes a foundation or anything else as part of the purchase that has value to you, on the exchange or return options you would have available after a purchase, and any of the other parts of your personal value equation that are important to you.
A mattress that may be relatively good value in one area of the country where choices are more limited or as part of one group of finalists that may not be as suitable, as durable, or compare as well to a mattress you are considering (based on all the other parts of your personal value equation that are important to you) may not compare as well with other mattresses in a different area of the country or as part of a different group of finalists that you are considering that may be more suitable, more durable, or would be a better “match” for your other criteria.
What size are you purchasing and is this a “mattress only” price or does your purchase include anything else besides just the mattress?
