Mattress size chart summary

How to Measure your Mattress

There’s no such thing called the perfect size for a mattress. The main reason is that choosing the right mattress size is mainly a choice based on personal preferences.

Factors like room size, how active a sleeper you are, and whether or not you share a bed influence which sizes best suit your needs. Understanding the dimensions and names will help you narrow down the options to help you find the right bed size to suit your specific needs.
Remember that height/thickness varies depending on the manufacturer and model, so there is no universal thickness for each mattress size.
