What mattress size do you need?

Getting the right size mattress can transform your sleep experience. Here is what you should consider when finding the best mattress size for you:

  1. Room dimensions: Ensure there’s enough space around the bed for easy movement and comfort. We recommend leaving at least 1m distance between the walls and your bed.
  2. Number of sleepers: Are you a single sleeper, or do you share your bed with a partner your children or pets? The more people in the bed, the more space you’ll need to sleep undisturbed.
  3. Body size and shape: Taller sleepers, or those who prefer extra space to stretch out, should consider a mattress with more length, like a queen, king, super king or California king. We recommend to allow 15cm from the edge of the mattress to your feet. Similarly, we recommend more width for a wider body frame.
  4. Sleeping positions: Side sleepers may need extra room to move, whilst back or stomach sleepers might be comfortable with less width. This consideration may also affect your preferred comfort level.

Single mattress

Sealy single mattresses are a great choice for children of all ages, and can also accommodate adults. Our single mattresses are 915mm wide and 1900mm (that’s nearly two metres) long so they make a great first bed, but still give adults enough room to move around. Single beds are also great space savers, and are perfect for smaller bedrooms.

Single XL mattress

Children grow fast and single XL beds are a popular choice for parents who want to get the most out of our ten-year lifespan. The single XL is the same width as a single (915mm), but offer extra length at 2030mm (compared to 1900mm). This provides extra room to stretch out, without taking up too much precious bedroom space. Single XL beds are great for holiday homes and guest rooms, as they can comfortably sleep both adults and children.

King single mattress

King single mattresses have both extra width (1055mm, compared to 915mm for regular singles) and length (2030mm, compared to 1900mm for regular singles), making them ideal for older children. This size is a great option for growing teenagers and taller adults who want more space, but don’t have room for a double or queen bed. While you’ll appreciate the extra sleep space, king single beds fit neatly into most bedrooms and are effective space-savers in apartments.

Double mattress

If it’s time to move out of your single bed, a double size (1385mm x 1900mm) is a great step-up. The extra width will feel luxurious for one person and can also accommodate couples. Although, we do recommend a queen mattress (or larger) if you regularly sleep with a partner. Double mattresses are great space-savers and are a versatile option if you’re looking for a guest bed; they are also a popular choice for teenagers as many bedrooms will accommodate a double size.

Queen mattress

There’s a good reason why our queen size mattresses are so popular, they offer a great size for couples at 1525mm x 2030mm and fit into most bedroom spaces. Cosy in winter, but with enough personal space in summer, queen size mattresses are a great choice. Delivering both comfort and practicality.

King mattress

Our Sealy king size mattress dimension is 1685mm x 2030mm, making it perfect for those who like a little more space. While it is the same length as a queen, the king size mattress delivers extra width, which means it’s large enough to provide a night of disturbance-free sleep – especially if you have young ones visiting your bed.

If you’ve got a bedroom with enough space to accommodate a king bed, it is an ideal choice. The mattress sits on two separate bases, which means you can get in and out of bed with less partner disturbance, making ‘king’ beds ideal for shift workers, early risers and restless sleepers.
