Mattress Sagging is a common complaint found across the Mattress Industry, Jamison Bedding does many things to try and alleviate this problem.
I don't care if you buy a $500 Mattress or a $2000 Mattress, many customers have problems with Mattress Sagging. There are several reasons for this. Mattress Manufacturers are making mattresses softer and softer. This requires greater thicknesses of foam to less dense foam products which tend to lose their shape quicker.
Jamison Mattresses use combinations of foam/Latex/Memory Foam on thicker Mattresses to curb the Mattress Sag issue. Latex is one of the greatest properties to find in a Mattress as Latex bounces back better and thus reduces Mattress Sagging. Jamison uses Latex in many models, even on their less expensive models, regardless of the fact that Latex in more expensive than traditional foam.
Another Problem causing Mattress Sagging is a rather touchy issue. We will just say that larger customers have a increased likelihood of Mattress Sagging. This is why it is of great importance to flip or rotate your Mattress so you switch sides, allowing your mattress to wear more evenly, especially if your spouse is smaller than you.
Another problem, I am guilty of this one, is sitting on the side of your bed, even if it is to tie your shoes. This causes your bed to Sag on the sides instead of in the middle. Jamison, on almost all models wraps the side of the Mattress, often called "Foam Encased". This allows a firm foam around the edge that will hold up better and reduce Mattress Sags at the edge.
These are a few problems causing Mattress Sagging, but let me say this. It is Impossible to eliminate all Mattress Sagging. Let me say that again. IMPOSSIBLE to eliminate ALL Mattress Sagging. Foams settle and will cradle some because we always sleep in the same spot. If we slept from side to side and moved every night and slept in a different spot, Mattress Sagging would be less noticeable. But, we sleep in the same exact spot night after night. If you have OCD and cannot stand seeing the Sagging spot in your Mattress, change where you sleep every night. .
