Apart from saving you extra expenses on a new foundation, it saves you the stress of sleeping on an unbalanced bed.

Cleaning and Design

Even if your bed is heavy and you know what your mattress weighs, you can prepare for times like this and even get extra hands if necessary.

What is the heaviest mattress size?

The heaviest mattress size is the king-sized mattress based on the surface area alone. However, this is not the only determining factor of a mattress weight.

Does a dense mattress mean better quality?

The answer is no. Weight is a byproduct of a good mattress, but the denseness does not indicate better quality. Other variables that affect a mattress"s weight, like the materials it"s made of, must be considered to determine the mattress"s quality.


While some factors determine mattress weight, the mattress weight in itself doesn"t resolve the quality of the bed. And, in extension, the quality of sleep.
