Hi HariS,
Unfortunately the specs you listed don’t contain any meaningful information that would make it possible to make any meaningful comments about the quality or durability of the materials. I would also guess that the coils aren’t 11" thick so there are probably some additional layers that are missing in the description. If you can find out the information listed here and post it on the forum I’d be happy to let you know if there are any lower quality materials or weak links that could compromise the durability and useful life of the mattress. In many cases you may be more successful in finding out the information that you need from your retailer (who should be the ones providing this information to their customers anyway) instead of directly through Restonic because there are many wholesale manufacturers that don’t provide this information directly to consumers and will only provide it to their retailers through their reps.
If for any reason they are either unwilling or unable to provide the information you would need to make an informed choice and to make meaningful comparisons with other mattresses I would pass the mattress by because buying a mattress where you don’t know the quality and durability of the materials inside it would be a very risky purchase.
These are all good quality materials that meet the minimum guidelines I would suggest for people that are in more “average” weight ranges although I would be cautious with this mattress for those that are in higher weight ranges (mid 200’s or higher). If you have confirmed that it’s a good “match” for you in terms of comfort, firmness, and PPP and that it compares well to your other finalists based on all the parts of your personal value equation that are important to you then it would certainly be well worth considering.
I don’t know the specifics of the protectors you are looking at so I really can’t make any comments about them but there is more about the pros and cons of different types of mattress protectors and some examples of each of them in post #89 here.
There is more about the 3 most important parts of the “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on suitability, durability, and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
While nobody can speak to how any specific mattress will “feel” for someone else because this is too subjective and relative to different body types, sleeping positions, and individual preferences, sensitivities, and circumstances and you are the only one that can feel what you feel on a mattress … outside of PPP (which is the most important part of the “value” of a mattress purchase), the next most important part of the value of a mattress purchase is durability which is all about how long you will sleep well on a mattress. This is the part of your research that you can’t see or “feel” and assessing the durability and useful life of a mattress depends on knowing the specifics of its construction and the type and quality of the materials inside it regardless of the name of the manufacturer on the label (or how a mattress feels in a showroom or when it is relatively new). There is more about the type and quality of the materials in the Helix and the BestMattressEver along with many of the other simplified choice mattresses in post #2 here in the simplified choice topic. Post #1 in the same topic would be well worth reading as well.
Both of them have great return/refund policies so you can try the mattress in your bedroom instead of testing it in a showroom with little risk outside of the time you spend sleeping on it or returning it should that become necessary.
When you can’t test a mattress in person then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help “talk you through” the specifics of their mattresses and the properties and “feel” of the materials they are using (fast or slow response, resilience, firmness etc) and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked or other mattresses you are considering that they are familiar with, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs and firmness levels to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with) than anyone else.
