What are the different types of super king size mattresses?

Nearly all manufacturers make their mattresses in this size. So your choice is limited only by budget and other specific requirements you may have. We’re always on hand to help with suggestions if needed!

What is the best super king mattress?

This is something only you can answer! There are some stunning mattresses available on the market today. One thing a Super Kingsize mattress will easily afford, however, is the option for a dual-tension firmness. One side can be a different firmness level than the other, and so a bed shared by a couple can suit both. There are many suppliers who can offer this, and we’re on hand to help if you need some advice!

Who is a super king size mattress best suited for?

The Super Kingsize mattress is the largest ‘standard’ size in the UK and offers a large amount of space. This is a very important factor when it comes to having a good night’s sleep, as the body needs to be able to move freely, allowing for good circulation and proper recuperation from the days wear and tear.
