It’s important that the mattress you bring home will be something that you’re going to be happy with for years to come. Buying the right bed and a comfortable mattress for your home is a serious investment.

Measure the length and width of the area where the new mattress is going to sit in your home. Many customers purchase a mattress, only to discover it’s way too big or small.

The right mattress size will align with for your physical needs and sleeping habits. You can refer to our Bed Buying Guide for more information to help you when buying a new mattress.

Mattress Size Guide

The bed should be the right size so you have adequate freedom of movement. Here are some tips for choosing the best size mattress for you:

  • Measure yourself and your sleeping partner.
  • The bed should be 10cm longer than the tallest person who will be sleeping in it.
  • If both partners sleep on their sides, there’s a good chance they pull their legs up and get into the foetal position. If this is the case, you may be able to get away with less than 10cm.
