HI S. You can read my experience here: Sealy Posturepedic Reserve, Firm - Reserve, Queen size, Firm
I had a $500 or so Serta that lasted for seven or so years and served me well. Instead of letting the company of my new bed haul it away, I kept it, and I decided to tear it apart to look inside. From bottom up:
(1) a little over 12 springs/ sq foot.
(2) 1/2" layer of cotton batting
(3) 1/2" layer of polyurethane (PU)
(4) padded quilted cover (probably some PU in it)
Compare with my new firm Sealy Posturepedic Reserve
(1) 25 springs per square foot.
(2) a thin 1/8" sheet of a polyethylene.
(3) 1" layer of egg-crated polyurethane foam (dense.)
(4) a 2.5" layer of egg-crated polyurethane foam (soft) with a strip of Visco memory foam 1/2" x 19.5" x 59" going across the hip section.
(6) There is an edge guard running around the perimeter of polyethylene 2.5" width.
(5) Then the quilted top which feels like it has some fairly dense polyurethane in it.
This was way too much padding for me. I was jack-kniving into it.
The old Serta was comfortable for seven years because the tension of the springs was perfect for comfort and support. From there it only needed a little bit of foam. Conversely the springs on my new bed are firmer, so extra foam was added for comfort. I ended up jack kniving into this foam. So I took out the PU and put in one 1" layer of 32ILD talalay latex and it gave great support. I recently added another 1" layer of 32ILD talalay and it is very comfortable and still good support.
I've heard Dunlop is very good. If he had incentive to lie, he'd have told you Dunlop was Talalay, not vise versa. You need to know the ILD. I would've suggested you simply get a firmer latex topper on your latex bed.
Basically, I believe there is a delicate balance between comfort and support, and it's different for every person. I can only relay you my experience, which is, too much padding caused my lower back pain.
I doubt very seriously that the problem is your bed frame. My sales guy told me that too; I think he just wanted me to go away. They will tell you anything except they sold you a bed that was poorly designed.
