What is the correct way to measure the height of a mattress?

We have prepared a number of recommendations to help you measure your favorite mattress at home or in a salon. To correctly determine the height of the product, you should measure the distance between the two sides. This figure will be the height. 

You can do this with a ruler, a construction level or a sheet of stiff cardboard. Place the mattress on a flat horizontal surface (floor or a sheet of chipboard). Place a light, straight object on top of the mattress. Measure the distance between the bottom and top object (between the floor and the ruler).
