Hi cindy,
The better options and possibilities I’m aware of in the Buffalo area are in post #29 here.
The most effective way to bypass “information overwhelm” and to find the best possible mattress for your particular needs and preferences is to identify and connect with the “experts” in your area. They already know what you would otherwise need to learn and will generally give you the best possible help and guidance.
Since there is a high quality/value factory direct manufacturer very close to you … that’s where I’d start
