Hope you don’t mind me jumping in here, but we bought the exact same SleepEZ bed and received it about a week ago and we’re also starting to wonder if we might need a layer change or topper. I know it takes a few weeks to fully transition to the new material, but here’s where we are.
I have soft-soft-med (listed top to bottom) on my side, so my 3 layers can’t really get any softer but could be rearranged to be firmer. While I do find it pretty comfortable (I’m actually not all that picky about beds) I also have the feeling you described that I kind of roll to the center of the bed, rather than sinking into the softness, despite how incredibly soft and bouncy this mattress is.
When we tested other brands of latex mattresses in the stores, I felt more like I was sinking in and nestled into the latex, not bouncing and floundering on top of it.
My whole body does sink down, but I’m still getting some pressure points on my shoulders/hips so it doesn’t feel like the latex is conforming, even though there’s so much give. It kinda feels more like I’m on a trampoline than a bed. 
This is not causing pain, but I’m waking up a lot b/c can’t get in a position and stay in it.
My spouse’s side has soft-med-firm and he’s waking up with back pain every day and he thinks he might want softer. We are planning to switch sides tonight to see if he likes my softer side any better. But at the same time, he says it bothers him that when he sits on the mattress he feels the foundation underneath, so then he wondered if he wants firmer. Contradictory I know.
Or maybe he just needs it to be thicker?
So far the above is making me start to wonder about:
a) The cover. It’s a pretty tight fitting cover and the cover fabric is not very stretchy, and it has a little more quilting than I thought it would. We got the thinnest mattress protector possible (the waterproof, sheet-thin Halo type). Maybe I just need to be closer to the latex so I actually sink down some? Should we try unzipping the top so we are sleeping more directly on the latex (with a protective barrier of course) to see how that feels? If we prefer being closer to the latex, should we think about getting a topper with a thin stretch cover?
b) The softness/thickness of the layers: Is the rolling effect I’m having more a result of it being to firm or too soft; or could that also be related to the cover pulling the top surface of the bed taut, keeping me from sinking in much (I’m petite). Do I actually need the top layer to be extra soft (which SleepEz doesn’t have I don’t think)? Or would getting a topper solve this problem as well?
