How Big Super King Size Bed? – Mattress Designer Explains All

What Is Super King Size in Cm?

Hello, I am Dr. Lawrence Woods, the head mattress designer at The Spinery, and I have dedicated my career to understanding the nuances of sleep and creating mattresses that cater to diverse needs. Today, I want to discuss an often overlooked factor in sleep quality – the size of your mattress. Specifically, I will explore the Super King mattress and how it can affect your sleep experience.

A super king size bed typically measures around 180cm (72 inches) wide by 200cm (78 inches) long, although sizes may vary slightly depending on the region or country. This size is larger than a standard king size bed and provides ample space for couples or individuals who prefer extra room while sleeping. It’s important to check the exact measurements before purchasing a bed to ensure it fits comfortably in your bedroom.

As a mattress designer, I recognize the importance of a good night’s sleep for our physical and mental health. The appropriate mattress size can make a significant difference, and the Super King mattress has become a popular option for those seeking additional space and comfort. So, what are the dimensions of a Super King mattress, and why might you consider it for your personal sleep haven?

Super King Mattress Dimensions

A Super King mattress typically measures 180cm x 200cm (71″ x 79″) or 200cm x 200cm (79″ x 79″), depending on the specific model and region. These dimensions make it the largest standard mattress size in many countries, offering abundant space for couples, families, and individuals who desire the luxury of extra room.

Super King Mattress Advantages

As a mattress designer, I can identify several benefits of choosing a Super King mattress:

Decreased sleep disturbances:

Sleeping in a smaller bed with a partner can cause frequent sleep disruptions, as tossing and turning can easily disturb the other person. A Super King mattress provides ample space for each person to move without disrupting the other, resulting in fewer sleep disturbances.

Enhanced sleep posture:

A larger mattress enables you to spread out and discover the most comfortable sleep position. This is especially crucial for those with chronic pain or orthopedic issues, as maintaining a proper sleep posture can alleviate pressure on the spine and joints.

Optimal sleep quality for taller individuals:

Taller people often have difficulties with smaller mattress sizes, as their feet might hang off the edge or they may feel cramped. The generous length of a Super King mattress accommodates taller sleepers, ensuring a comfortable and restorative sleep.


A Super King mattress provides the space necessary for families with young children or pets to sleep comfortably together. This can be especially helpful during times of illness, sleep training, or simply for weekend snuggles.

Super King Mattress Considerations

While a Super King mattress offers numerous benefits, there are also some factors to consider:

Space requirements:

Make sure your bedroom has sufficient space to accommodate a Super King mattress without compromising the room’s functionality. Take into account the layout and other furniture when making your decision.


A larger mattress often comes with a higher price tag, so be prepared for a greater initial investment. However, the advantages of improved sleep and increased comfort may be well worth the expense.

Bedding and accessories:

Super King mattresses necessitate larger sheets, duvet covers, and other bedding items, which can be more expensive and harder to find. Keep this in mind when shopping for your new sleep arrangement.

Moving and transportation:

Due to their size, Super King mattresses can be difficult to move and transport. If you anticipate frequent moves or have limited access to your bedroom, a smaller mattress size may be more practical.

In conclusion, a Super King mattress can significantly enhance the sleep experience for those seeking extra space and comfort. As a mattress designer, I encourage you to carefully weigh your personal needs, room dimensions, and budget before making a decision. Remember, investing in a mattress is an investment in your health, and selecting the right size can profoundly impact your sleep quality and overall well-being.

What is the difference between a King and a Super King mattress?

A King mattress typically measures 150cm x 200cm (59″ x 79″), while a Super King mattress measures 180cm x 200cm (71″ x 79″). The Super King offers more width and/or length for added sleeping space.

Can a Super King mattress fit into a standard bedroom?

While a Super King mattress is larger than other standard mattress sizes, it can fit into a standard bedroom as long as there is enough space for it and other essential furniture. Carefully measure your room and consider the layout before purchasing a Super King mattress.

Do I need a specific bed frame for a Super King mattress?

Yes, you will need a bed frame specifically designed to accommodate a Super King mattress. Make sure to check the dimensions of the bed frame before purchasing to ensure it matches the size of your chosen mattress.

Are Super King mattresses suitable for people with back pain?

A Super King mattress can potentially benefit individuals with back pain by providing more space to find a comfortable sleep position. However, it’s essential to choose a mattress with the appropriate firmness and support for your specific needs.

Is a Super King mattress worth the investment?

The value of a Super King mattress depends on your personal preferences, sleep requirements, and budget. If you prioritize space, comfort, and reduced sleep disturbances, a Super King mattress may be worth the investment.

Are there any special care instructions for a Super King mattress?

Care instructions for a Super King mattress are generally similar to those for other mattress sizes. Regularly rotate or flip the mattress (if recommended by the manufacturer), use a mattress protector, and clean spills promptly to maintain its quality and longevity.

Can I use a mattress topper on a Super King mattress?

Yes, you can use a mattress topper on a Super King mattress. Ensure that you purchase a topper specifically designed for a Super King size to achieve the best fit and comfort.

How do I move or transport a Super King mattress?

Moving a Super King mattress can be challenging due to its size. It is best to enlist the help of others, use proper lifting techniques, and consider using a mattress bag or cover for protection during transport. If possible, hire professional movers to ensure safe and efficient transportation.

Can a Super King mattress help with snoring and sleep apnea?

While a Super King mattress may provide more space to find a comfortable sleep position, it is not a direct solution for snoring or sleep apnea. Consult a medical professional for appropriate treatment options and consider a mattress with proper support to maintain airway alignment.

How often should I replace my Super King mattress?

The recommended lifespan for most mattresses, including Super King mattresses, is around 7-10 years. Factors such as the mattress quality, usage, and maintenance can impact its longevity. Replace your mattress when it no longer provides adequate support and comfort.

Is King Size the Same as Super King?

As a general rule, King Size beds and Super King beds are not the same sizes. King Size beds typically measure 150cm x 200cm, while Super King beds usually measure 180cm x 200cm. It’s important to check the exact measurements of a bed before purchasing, to ensure it will meet your needs and fit comfortably in your space.
