The search for the perfect mattress…would be a never-ending search if you’re looking for one that fits all of the check boxes in your criteria.
While many mattresses can remain in top quality and shape up to a few years, the truth of the matter is that over time, these do sag and lose its form and shape. This is because the mattresses are made and produced using old technology. And they come from a softer material that doesn’t “bounce back” after use. The mattresses become less resistant, which is what happens when it starts to sag and lose its shape. Then you would start feeling pain every time you sleep. Sagging is one of the causes of discomfort and back pain.
