Hi bertiebus,
Unfortunately there is no way for anyone else to know how a mattress will feel and perform for someone else based on specs and you will need to trust your own personal testing which is really the only accurate way to know. Post #1 here has some suggestions about how to test a mattress as objectively as possible (rather than testing for the much more subjective “feel” of a mattress) which can improve your odds of making a suitable choice. The only thing I can speak to is the quality and value of a mattress. It may also be worth reading post #2 here and post #5 here.
From a quality perspective the materials are good and there are no obvious weak links in the mattress. From a “commodity value” point of view the value is also great. There are also many other parts to value though which may be part of your personal value equation and only you can know your own confidence level in the suitability of the mattress as well as all the other objective, subjective, and intangible parts of a mattress purchase that are most important to you. If the mattress is suitable for your needs and preferences it would seem to me to be great value. If it’s not … then no matter what it’s “commodity value” … it would have little value for you regardless of the price you paid. This is the question you would need to decide based on your own personal testing.
The adjustable bed thread here may also help you with making choices between adjustable beds and has some good value references as well.
