What is GSM Fabric in a mattress?

GSM or Grams per Square Meter is a dimensional attribute required for determining how heavy the fabric is. For example, a woollen yarn will have higher GSM in comparison to satin or silk. This is because the total amount of matter in one square meter of wool is far more than the silk/satin. 

Similarly, when we talk about the GSM of a mattress top fabric, we usually determine its weight and other related features.
