Hi GiantsFan2029,
Welcome to the Mattress Forum! 
There is more information about choosing an adjustable bed in post #3 here and the main adjustable bed topic that it links to that can help you choose an adjustable bed based on price vs features comparisons and also includes some retailers that you can use as good sources of information about the features of the adjustable beds they carry and as pricing references as well (in post #6 in the main adjustable bed topic). Of course there are many other sources as well and prices can change on a regular basis so I would also include some internet searching in your research. I would also keep in mind that online advertised prices are often price controlled so make sure you call the stores you are considering to find out their best prices rather than just looking at websites. Here is another adjustable bed base thread with some manufacturers listed.
I would consider all the major adjustable bed manufacturers to be closely comparable in terms of reliability, so I would use price and feature comparisons to choose between them. I would also give some careful consideration to the type of features that you may find useful over a longer period of time because some of the features they offer may seem very “enticing” when you are shopping but some people may find that they don’t use them as much as they thought they would once the novelty has worn off.
While I’m happy you found a new mattress :cheer: , I would be more cautious with Amerisleep , as they tend to use some lower quality materials than what I would normally suggest in the durability guidelines . Hopefully you were able to learn the density of all of the foam layers within your mattress before making your purchase. Amerisleep, along with Astrabeds and Simplyrest, is part of onemallgroup, which specializes in viral marketing in partnership with Kim Tyrone Agapito. The good news is that you did make a smart decision to purchase a mattress that does allow for a return should it not turn out as well as you had hoped for.
I hope the adjustable bed base information helps you on your search, and you should have no issues with your new mattress bending with any power foundation.
