Mattress Guide

Size does matter

The first decision to make is the size of your mattress. There are many options available but here are some handy tips to factor in when choosing the best size that suits you:

  • A mattress should be at least 10cm longer than the height of the tallest person using it.
  • The width of the mattress should allow you to be able to put both your hands under your head without your elbows touching the edge of the mattress or the person sleeping next to you.
  • European mattress sizes differ from UK mattress sizes.

The Perfect Mattress size


Size: 70cm x 140cm

Best suited for: Toddlers

A toddler sized mattress is the perfect size for kids aged between one and three and is a great starter for kids ready to move out of their cots. Care should be taken to ensure that the mattress fits perfectly in your kids' bed. Turning the mattress regularly will also reduce wear over time.

The small single will fit narrower kids' bed frames and guest beds. It's the perfect size if you're trying to save on space and is great for a spare room as it can be easily moved when you have guests and visitors.

This size is great for people who sleep on their own and is a good longer term option for a child as it will last well into their teens. Single sized mattresses are also a great option for larger spare rooms and guest bedrooms.
