Our Best Mattress Size Guide

Other than personal taste, there are a number of factors to think about before selecting your mattress size. Have you considered: the dimensions of the bedroom, if you plan to share the bed with your partner or pets, the importance of open space versus sleep space to you? There are size descriptions below and a King Mattress size guide that will give you a better idea of how to choose a mattress online.

King Mattress

80"
76"

The biggest mattress in terms of width, the King mattress measures 76 inches wide and 80 inches long (193 x 191 cm). The King memory foam mattress offers plenty of space for couples and room to spare for children or medium-sized pets. We recommend having a larger master bedroom to fit the king of at least 12 x 10 square feet. Fun fact: the King mattress was invented in 1890 and could fit up to 15 people!
