What Size is a Super King Mattress?
A UK super king mattress measures 180cm wide by 200cm long (6ft x 6ft 6"). This makes it the largest standard mattress size in the UK - 30cm wider than a king size and 45cm wider than a double. To put it another way, a super king provides the same width as two single mattresses placed together, giving each sleeper their own generous space. You can visit our mattress size guide for more detailed advice.
What Are the Benefits of a Super King?
A super king mattress transforms your sleep experience in several ways:
- Maximum Personal Space - Each sleeper gets 90cm of width, so you're far less likely to invade your partner's side during the night.
- Reduced Partner Disturbance - The extra width means movement on one side of the bed is less likely to travel across and wake your partner.
- Room for the Whole Family - Ideal for parents with young children or pets who occasionally join them in bed.
- Better Sleep Quality - We all snooze better when we have enough space to get comfy!
- Luxury Feel - There's a reason hotels use larger beds - spreading out creates a more indulgent, restful sleep environment.
- Future-Proof Investment - If you're upgrading from a double or king, a super king ensures you won't outgrow your bed as circumstances change.

Super King Mattress Firmness Levels to Choose From
Choosing the right firmness ensures proper support and comfort throughout the night. In our range, you’ll find the following:
- Soft - Plush, cushioned feel that allows your body to sink in; recommended for side sleepers and lighter individuals who need pressure relief at the shoulders and hips.
- Medium Firm - The most versatile option, balancing cushioning with support; suits combination sleepers who change position throughout the night.
- Firm - Solid, supportive surface with minimal sinkage; best for back sleepers, front sleepers, and those needing extra lumbar support.
Will a Super King Mattress Fit My Bedroom?
A super king requires a generously sized room. At 180cm wide, you'll need space on either side for access. We recommend at least 60-75cm clearance between the bed and any walls or furniture. A bedroom of around 4m x 4m or larger works best. Don't forget to measure doorways, staircases, and hallway corners for delivery. Many of our mattresses arrive vacuum-packed and rolled, making them easier to manoeuvre through tighter spaces.
Will a Super King Mattress Fit My Bed Frame?
Yes, a super king mattress fits any standard UK super king bed frame with internal dimensions of 180cm x 200cm. This includes divans, ottomans, and sleigh beds. Always check your frame's internal measurements before ordering, as decorative bed frames (particularly upholstered or sleigh styles) may have external dimensions larger than the mattress itself.
