Super King Size Bed: Dimensions & Irish Buying Guide

Anyone who’s ever woken up clinging to the edge of a king-size mattress knows the feeling of wanting more horizontal real estate. That extra 30 cm of width — the full width of a standard pillow — is exactly what a super king size bed delivers, and in Ireland it’s the widest standard option you can buy, so this guide lays out the exact dimensions, the real differences from a king, and what Irish retailers actually stock.

What size is a super king bed?

A super king size bed measures exactly 180 cm wide by 200 cm long — that’s 6 feet by 6 feet 6 inches. This is the same footprint used across Ireland and the UK, and multiple Irish retailers confirm the standard. Caseys Furniture (Irish furniture retailer) says a typical super king “measures 180 cm by 200 cm,” while Des Kelly (Irish bed specialist) and Right Price Beds (bed retailer) give the same numbers.

• Width: 180 cm (6 ft) — 30 cm wider than a king
• Length: 200 cm (6 ft 6 in) — same as a king
• Area: 3.6 square metres

The super king is sometimes called a “6ft super king” because of its 6-foot width, and Irish shoppers will see both terms used interchangeably at stores like Harvey Norman Ireland.

The implication: the extra width is substantial for couples.

Which is bigger, super king or king size bed?

Three key numbers, one clear pattern: super king and king share the same length, but super king offers substantially more width.

Snooze Mattress (Irish mattress retailer) confirms the super king is 30 cm wider than a king mattress. BigMickey.ie (Irish bed frame specialist) puts it more directly: “Superking mattresses are a whole foot wider than king size.”

What this means: If you’re deciding between king and super king, the choice really comes down to width. Both beds offer the same 200 cm length, so taller individuals won’t gain legroom — but couples who find themselves fighting for space on a king will notice the difference immediately.

What is the largest bed size in Ireland?

The super king is the largest standard mattress size available in Ireland. Homeline Furniture (Irish furniture retailer) states this directly, and no other common standard size exceeds 180 cm × 200 cm.

• Super king: 180 × 200 cm (largest standard)
• King: 150 × 200 cm
• Double: 135 × 190 cm

Custom-made beds larger than super king do exist — but they are not standard sizes and typically require bespoke orders from specialised manufacturers.

The catch: custom sizes are an option but require planning.

What size is a super king bed in Ireland?

Ireland uses the same bed-sizing standards as the UK. A super king in Ireland means the same 180 cm × 200 cm footprint you’d find in any British retailer. Snooze Mattress confirms: “UK and Ireland follow the same sizing standards.”

Alternative names for 180×200 bed

The naming varies by region:

• Ireland / UK: super king size
• Europe (mainland): often called “queen” or simply “180×200”
• Australia: sometimes referred to as “king size”

What this means: If you’re shopping online from a European site and see an 180×200 cm bed, it will fit a super king mattress — but make sure the seller confirms the mattress size matches Irish standards.

How much space do you need for a super king bed?

A super king bed needs more than just floor space for the mattress. Mattress Reviews Ireland recommends:

These recommendations are practical: less than 60 cm on one side makes it difficult to make the bed or move around. Mattress Reviews Ireland also advises measuring doorways and stairwells before purchase — a super king mattress may not fit up a narrow staircase.

The takeaway: measure carefully before buying.

For Irish shoppers, the super king size bed is the clear winner if bedroom space allows. The decision is straightforward: if your room measures at least 4 m × 4 m and you value personal sleeping space, the extra 30 cm of width is worth every euro. For anyone in a smaller room, a king-size will still provide the same length — just 30 cm less room to roam.
