Hi CarlBruh.
Welcome to our Mattress Forum.
I can see you have been given some great advice and resources from both GhostBed and ebs.
ebs has gotten you started with some great resources. In general, it is impossible for anyone to choose for you which softness would be best as only you can feel what you feel on a mattress; people with different body types, sleeping positions, or preferences can make very different mattress comfort choices from each other. So you’d first need to do some narrowing down based on your preference of materials, needs, and the other parts of your Mattress buying personal value equation and things that are most important to you.
ebs mentioned the Mattress Durability Guidelines, and I would add that you also take a look at this resource about the different comfort needs related to the different sleeping positions. We also have an article all about varying budgets, including lower budgets.
And, as ebs mentioned, it’s always a good idea to reach out directly to the manufacturer or retailer you’re looking to purchase from to share your sleep stats (height, weight, any special comfort needs, sleeping position, etc.) and ask for their guidance. This is also a good way to evaluate whether or not you truly wish to purchase from a specific company; what you are looking to find out is their ability and willingness to disclose the materials in their mattresses and their knowledge, experience, and ability to give you the guidance that is necessary to help you make meaningful comparisons and your best possible choices.
Finally, I’d also recommend looking at our Mattress Shopping Tutorial. There are a number of tips there that may be of use for you.
Hoping this helps assist you in moving forward with your mattress shopping!
