Hi thecallmebill,
I think the first suggestion I would make is to read post #1 here which is a step by step process that can greatly help improve the odds of finding the best quality/value mattress in your area that is the most suitable for your needs and preferences.
As you can see from the information that is linked in the post … I would personally avoid all of the brands you are mentioning.
I would also never shop by brand or brand recommendations (except for the major brands which I would exclude) but only by the combination of materials that are in a mattress and how well they meet your needs and preferences. These materials are available to any manufacturer and a mattress is only as good as the materials that are in it and how well they suit your body type, sleeping positions, and individual preferences regardless of the brand label on the mattress. No matter what materials you prefer … making sure they are the highest quality available in your budget is the key to quality, value and durability.
Because the quality of the materials that are in your mattress is the most important part of it’s long term performance … who you buy from can be even more important than what you buy.
Arming yourself with some basic information about the different materials and types of mattress and then working with either manufacturers or better sleep shops that offer good quality, value, and service and will fully disclose the details of every layer of the mattresses will lead to the best possible choices available … regardless of the brand.
