Hi Matchmee,
I’ve never used an adjustable bed that has the features that you mentioned and they probably wouldn’t be all that important to me but the features that are important to each person may be very different from from someone else. Hopefully some of the members that have an adjustable with the features that you are mentioning will see your post and make some comments about how useful they find them.
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 and 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.
I would treat all the major adjustable bed manufacturers as being closely comparable in terms of reliability so choosing an adjustable bed is really a matter of choosing the model that has the features that are most important to you at the best price regardless of the manufacturer.
Post #4 here may be helpful as well if you are considering the Ergomotion/Softide 8300.
