Hi chicagorob,
I’m not so sure that I would have taken the same approach since you lose some of the main benefits of choosing a component mattress in the first place where you can use your bedroom as a testing ground instead of having to go to a showroom to try different mattresses and different firmness levels but of course these types of choices are always up to each person and what they believe is best for them.
Now that you are starting over again … the first place I would start (if you haven’t read it already) is the mattress shopping tutorial here which has all the basic information, steps, and guidelines that can help you make the best possible choices … and know how and why to avoid the worst ones.
You certainly have more options that just these two (the Casper or an innerspring mattress) either online or locally and there are also many hundreds of innerspring mattresses that are very different from each other that may use different types of springs and have different types of comfort layers with different firmness levels as well so even if this is the type of mattress that you tend to prefer it would still be important to make sure that you do some careful testing to choose the one that is the best “match” for you in terms of PPP and to check and make sure that it also uses good quality materials so that it doesn’t end up softening or breaking down much too quickly.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here.
The Casper mattress is an “all or nothing” choice and with companies that only offer a single mattress it would be the “best” choice for a relatively small percentage of the population, a “good” choice for a slightly larger percentage, and an “OK” choice for a larger percentage yet so it depends on whether you are confident that it’s “the best” or a “good” or an “OK” choice for you compared to any other mattresses you are considering. Of course if it’s not a “good enough” choice for you then they have a great return policy so you can just return it and begin your search over again. A forum search on Casper (you can just click this) will bring up more information and feedback about them as well.
If you let me know your city or zip code I’d also be happy to let you know about any of the better options or possibilities I’m aware of in your area.
