Hi coast,
The first thing I would suggest for the first couple of weeks is to make as few changes as possible so you can adjust to the feel and performance of a new mattress that is quite different from what you are used to and to let the mattress break in a little. If you make changes too quickly then things can become quite confusing as you may not be able to tell if any change in your experience is because of adjusting to a new mattress or from the change itself and your body won’t have the time to “catch up” to the changes you are making.
Once you have spent some time sleeping on your new mattress … if you feel that you want to make some changes to the layering then the first step is always a more detailed conversation with the manufacturer to talk about your experience so they can use their knowledge and experience with their mattresses to make some suggestions about the type of changes that may be most helpful. There are also a few other suggestions in post #2 here that may also be helpful.
[quote]After sleeping two nights on side 2 I felt a little lower back pain. I did not experience this on the firmer Sealy.
I slept one night on side 2: this was a bit better.[/quote]
Both of your comments here are about side 2. Did you start on side 1 or side 2?
Just to clarify … the layering you listed for side 1 would be softer than the layering for side 2.
[quote]I could replace the middle firm with medium in side 2. However, it don’t think I like the “sink in feel”.
Are there other avenues to explore?[/quote]
When the time comes, some of the other possibilities that may be worth considering depending on your experience and any “symptoms” you are experiencing on your mattress would be slightly firmer comfort layers where you won’t sink in quite as much such as (top to bottom) M/S/F or M/M/F (you would probably need another M layer for this). M/F/F would also have a firmer comfort layer but would be firmer overall than any of your other configurations.
Once again though … I would wait a little longer before making any changes and then I would make any changes after that slowly and incrementally so you give your body time to catch up to the changes you are making and so you can make more accurate assessments about the effect of each change you make.
