1. What are the main differences between a 'Double' and a 'King' size mattress? Are there specific size differences/ shapes?

“When looking to purchase a new bed or mattress, you must first consider its size. Beds that are too small for you can really affect the quality of your sleep, whilst a larger bed may present some challenges depending on ease of accessibility to your house.


“In Britain, Single, Double, King, Super King, and Emperor sizes are most common, but each mattress size may differ depending on the brand and country of origin. A ‘Queen’ size mattress is more commonly found in America and is a close equivalent to a UK ‘King’ size mattress in the UK (150cm X 200cm). A British ‘Super King’ (180cm x 200cm) is similar to a ‘King’ size mattress in the USA.”


“The terminology for mattress sizes differ across Britain, Europe, and America so it is crucial when choosing a new bed frame, mattress, duvet, or bed linen that you double check sizes first before purchasing.”


2. What type/age of person would each suit?

“Having the space to get settled and sleep uninterrupted is universally key for everyone. You should feel supported across the whole width of the bed and be able to move freely. And, if you share your bed, this is even more important so you can minimise disturbing each other.


“A classic single bed is perfect for solo adult sleepers and older children. It is typically 90cm x 190cm and is great for a smaller bedroom as it leaves plenty of floor space free.

“A standard double mattress size offers just enough space for couples at 135cm x 190cm, so each person has just 67cm of space, which is actually smaller than a standard single bed. So, if you enjoy your space or are broader or taller it is definitely worth upgrading to a larger size mattress.


“If you like to stretch out a little more, a King-sized mattress could be a good fit as, at 150cm x 200cm, it provides extra room both lengthways and across. It is also one of the most popular sizes sold in the UK.


“Offering couples the opportunity to truly spread out and delight in luxurious personal space, a Super King mattress, which is 180cm x 200cm, allows for the same amount of space as a single bed per person to offer uninterrupted comfort.


3. Is there a price difference?

“Sleep is pivotal to our health, both physically and mentally, so mattresses are a positive investment in your wellbeing. It’s recommended that you change your mattress every seven years, so finding the right perfect mattress once rather than purchasing a new one multiple times over within that period makes better financial sense.
