Hi sunbird,
The only way to assess any mattress in terms of quality and value is to know the details of all the layers and components inside it. Unfortunately the major manufacturers (including Simmons) don’t disclose this information so when you purchase one of their mattresses you are making a completely blind purchase. if you do happen to be able to find out the specifics of the quality of their materials … in most cases you will find they use lower quality materials and sell for higher prices than similar mattresses made by smaller independent manufacturers across the country. As you can see in post #1 here (which includes all the basic information, steps, and guidelines that can help you make the best possible choices) I would always avoid a blind purchase where there is no way for you to know the quality or value of what you are buying. You can’t feel the quality of the materials inside a mattress in a showroom and lower density/quality foams will soften and impress more and more quickly than higher quality foams.
Only you can decide this but I’m happy to provide you with all the information and guidelines you need to make the most informed decisions. I can tell you that I personally wouldn’t purchase a mattress where there was no way to make meaningful quality or value comparisons with other mattresses because for me the risk would be too high but each person may use different criteria for their personal value equation.
The only way to know if it was a good choice would be to have the information you need to assess its quality and value and be able to make meaningful comparisons with other mattresses and unfortunately the information you need isn’t available. I can also tell you that price is not a good indicator of quality and that negotiating a “good price” (see post #6 here) may not always be what you believe it is.
There are too many variables and unknowns to use height and weight and the specs of a mattress to make the most suitable choice based on “theory” (see mattress firmness/comfort levels in post #2 here). The guidelines are more generic and not specific to any individual and meant to give you some insights into different types and designs of mattresses and some of the concepts that can help you make a good choice. Your own careful and objective personal testing (using the mattress testing guidelines) and ultimately your own long term experience on the mattress is the most reliable way to know which mattress is most suitable for you. In addition to this … Simmons also doesn’t provide any of the “comfort specs” of their mattress so personal testing is the only possible way to evaluate the mattress in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) and of course this still doesn’t deal with the quality of the materials and how long the mattress will maintain its comfort and support which is the reason you are buying it in the first place. i would also keep in mind that the biggest reason a mattress needs to be replaced is the loss of comfort and/or support and that neither of these are covered by warranty (see post #174 here).
I would treat any blind purchase as “buyer beware”.
