Hi Musebell,
Post #3 here talks about trying to compare one mattress to another in terms of comfort and performance and some of the difficulties involved.
It’s much easier to compare mattresses in terms of quality, durability, and value because knowing the quality details of the materials in a mattress allows you to do this but small differences in the types of material, layering, and design can make a big change in the feel and performance of a mattress even if the quality of the material and the design is similar. In addition to this, different people have different body types, sleeping styles, and different perceptions which can all affect how a mattress feels so in many cases it’s not possible to predict how a specific person may feel on a mattress that has some differences from another one that one person may think makes a big difference and someone else may not feel at all. It’s usually much more effective to compare every mattress to a more defined set of personal “ratings” instead of trying to compare them to another mattress.
The only way to approximate how close two mattresses may be for you is either in personal side by side testing or with a more detailed conversation with an online retailer or manufacturer who knows all the details of their mattresses and may know how their various models compare in terms of feel and performance to some of the more popular mattresses in the general market.
While it’s usually a good idea to test and research locally first to get a good idea of how different combinations of materials can feel to you (which may uncover some very good local quality/value that you can test in person or can help an online manufacturer or retailer help you make better choices) … if you are looking in an online direction then some of the better memory foam choices I’m aware of are listed in post #12 here.
If you let me know your zip or city I’d be happy to let you know about any of the better local options or possibilities I’m aware of.
Hope this helps.
