Hi Janie,
The first place I would start your mattress research is the tutorial post 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.
I would also be very cautious about using reviews or other people’s experiences on a mattress (positive or negative) as a basis for your choice (see post #13 here) because they will tell you very little about how suitable or durable a mattress you are considering would be for you.
There is more about the most important parts of the “value” of a mattress purchase in post #13 here but outside of PPP (Posture and alignment, Pressure relief, and Personal preferences) which is always the most important part of any mattress purchase … a mattress is only as good as the quality of the materials inside it … regardless of the name of the manufacturer.
I would be very cautious about purchasing any mattress where you don’t know all the details of all the materials and components inside it (see this article) so you can compare them to the guidelines here and make sure there aren’t any weak links in the mattress and make more meaningful comparisons with other mattresses.
If you can find out the specifics of all the layers in the mattress you are looking at then I’d be happy to make some comments about the quality of the materials.
If you can’t find out the information you need to know to make an “informed choice” … I would pass the mattress by because the risks of making a “blind purchase” or a mattress that uses lower quality materials are much too high and are one of the most common causes of buyers remorse much too quickly after a purchase.
As I mentioned in one of my replies to your other posts … if you let me know your city or zip code I’d be happy to let you know about any of the better options or possibilities I’m aware of in your area.
