A super king mattress is the largest standard sleep surface available in Singapore. It offers exceptional width and is designed for those who want maximum space — whether for a couple who values personal sleeping room, a family that shares the bed, or a homeowner who simply wants the most generous option available in a large bedroom.
But a super king is a significant purchase, and it is not right for every situation. This guide helps you understand what a super king actually offers, whether it suits your home, and what to look for before you buy.
Super King Mattress Dimensions in Singapore
Super king dimensions in Singapore are not always standardised across brands. Most commonly, a super king measures approximately 200 cm wide by 200 cm long, though some brands offer a 183 cm x 200 cm configuration. Always confirm the exact centimetre dimensions of any mattress before purchasing, particularly if you are buying a matching bed frame.
The key distinction from a standard king — typically 183 cm x 190 cm — is both the width and, in some models, the additional length. This makes a noticeable difference for taller sleepers or those who want more room to move freely.
Who Is a Super King Mattress Best For?
• Couples in large master bedrooms in condos or landed properties who want maximum personal sleeping space.
• Families who regularly share the bed with young children and need room for everyone to sleep comfortably.
• Taller individuals who benefit from the extra length beyond the standard 190 cm.
• Homeowners upgrading a large bedroom where a standard king already fits and there is room for something larger.
A super king is not the right choice if your room cannot comfortably accommodate it. Unlike a standard king, which already requires a generous bedroom, a super king needs a substantially larger space to feel balanced and accessible.
Will a Super King Fit Your Room?
This is the most critical question before buying. At approximately 200 cm wide, a super king requires a bedroom that is at least 3.5 to 4 metres wide to allow comfortable access on both sides and a sense of balance in the room.
Most HDB master bedrooms are unlikely to accommodate a super king comfortably. Larger condo master bedrooms and landed property bedrooms are more suitable. Measure carefully and account for other furniture in the room before committing.
Also check your delivery access points — a super king mattress needs to navigate corridors, lifts, and doorways, which in some apartment buildings can be a challenge. Confirm this with the store before ordering.
What to Look for in a Super King Mattress
Edge-to-Edge Support
In a mattress this wide, consistent support from the centre through to the edges matters. A poorly constructed super king may feel well-supported in the middle but compressed and unsupported near the sides. Look for a mattress with reinforced edges or a construction designed to maintain consistent support across the full width.
Motion Isolation
With two people sharing such a large mattress, motion isolation remains important. A pocket spring construction where each spring moves more independently helps ensure that movement on one side does not disturb the other person.
The Somnuz pocketed spring mattress collection is designed with motion control in mind and is a practical starting point for couples sharing a large bed.
Breathability
A larger sleep surface can retain more heat if the materials are not designed for airflow. In Singapore's climate, this matters particularly. Look for natural materials, breathable cover fabrics, or pocket spring constructions that allow air to circulate more freely.
Quality and Durability
A super king is a significant investment. Choosing a mattress built with quality materials and backed by a meaningful warranty gives you confidence that the comfort and support will hold up over time.
The Somnuz Luxury Series offers elevated materials and a more refined construction, making it a considered option for those investing in a premium sleep surface.
Bedding for a Super King
Standard king bedding will not fit a super king mattress. Make sure you source fitted sheets, mattress protectors, and duvets specifically sized for super king dimensions. Not all retailers stock super king bedding in Singapore, so it is worth planning this alongside your mattress purchase.
Frequently Asked Questions
What is the size of a super king mattress in Singapore?
A super king mattress in Singapore is typically around 200 cm wide by 200 cm long, though dimensions can vary between brands. Always confirm the exact measurements in centimetres before purchasing, and ensure your bed frame is sized to match.
How is a super king different from a king?
A standard king is typically 183 cm wide by 190 cm long. A super king is wider — often 200 cm — and in some models, also longer. The super king offers significantly more sleeping space and requires a correspondingly larger bedroom.
Is a super king worth it for couples?
For couples in a room large enough to accommodate it, a super king can offer excellent sleeping comfort — more personal space, less disruption, and room for children who occasionally join. Whether it is worth the investment depends on your room size, budget, and how much space you genuinely want.
Will a super king mattress fit in a Singapore apartment?
It depends on the size of the apartment and the master bedroom. Standard HDB bedrooms are unlikely to accommodate a super king comfortably. Larger condo master bedrooms and landed property rooms are more suitable. Always measure before buying.

Yes. The Somnuz experience centre at 134 Joo Seng Road, Level 2, Singapore 368359 is open daily and allows you to try the range and compare options in person before making a decision.
