My wife and I purchased a Cal King Wynkoop St Plush from Sleep Nation in Lone Tree, Colorado back in January 2015. I’m a larger guy at 6’3" 265lb and my wife is 5’10" at 130lb and we loved the bed at first. It was very soft and we just melted into it. However, in the past couple years the bed has become much firmer than we wanted. This model is not flippable. However, it looks like SleepUnion (again, looks like the same company as Sleep Nation) has the same mattresses, but at least the new Wynkoop is flippable. However, it’s very expensive.
I’m disappointed that our current mattress appears to be one solid piece. I unzipped the cover today and saw that the bottom appears to be standard yellow foam. There is certainly latex on the top, and through the middle, but again it appears to be one thick piece.
For these reasons, I’m looking at DIYing the bed in several layers. A DIY approach appears to be more than 50% cheaper than the current offering at Sleep Union. But because they never told us what the layers were, I can’t really replicate what we had. With that said, we’re really wanting something that will allow us to melt into the bed and still give us support on the lower back and in the hips to ribs regions like our mattress originally did. I’m OK with replacing the top layer every 5-8 years, but I’m hoping I won’t have to do that.
I am curious about these layers. Do the layers tend to move over time? Like, do they slide sideways and need to be reoriented? I’ve also read that there was a particular brand latex layer that had a glue seam running down the middle of the bed. Do all brands have this?
With all this said, does anyone have any recommendations? Should I just start emailing some companies (Latex Mattress Factory, Arizona Premium Mattresses)? Thank you!
EDIT TO ADD:
I forgot to mention that we have a nice platform now with many firm slats that allow air flow and central support. We also have two twin box frames (metal rod and wood) under the latex mattress. These have fabric covers but allow the mattress to breathe.
