Some pics of the updated foam mattresses, taken in the San DIego store 4/13/2014. I’ve posted some comments in post #58 here.
Morgedal 2-layer poly, probably medium firm (mislabeled firmness per salesperson)
Morgedal 2-layer poly, firm. Look closely to see the dividing line between the layers at about 4.5" on the measuring tape.
Here is a closeup where you can see the dividing line a little better:
Matrand memory foam + poly
Matrand latex + poly
Matrand latex label - 12cm (4.7") Mountaintop C3 foam
Myrbacka memory foam + poly
Myrbacka latex + poly
Top of Myrbacka latex sample unzipped. Note sample is only half the length of mattress. Zoning is not as evident on top of latex, but bottom is glued to polyfoam so can’t take a picture of that.
Morgonava latex
Bottom of Morgongava latex sample unzipped. Full length of mattress. You can see the seven zones created by different-sized holes.
