UK Grand Super King Mattresses

The UK grand super king (213 x 200cm) takes width beyond the super king: a full 7ft across, usually made to order by specialist British bed makers.

Why choose a grand super king?

  • It adds another 33cm of width over a super king, the largest standard UK size.
  • It's a specialist size, typically handmade to order rather than kept in stock, so lead times are longer than for standard sizes.
  • Two adults get over a metre of width each, enough that a child or a dog climbing in at night doesn't push anyone to the edge.
  • Mattresses this size often come in two sections, which makes delivery and turning more manageable.

Allow at least 3.4m x 2.9m of floor space; bedding comes in bespoke or emperor sizes from specialist suppliers.

How big is a grand super king mattress?

213 x 200cm, or 7ft wide by 6ft 6in long.

What base does a grand super king need?

A specialist 7ft base, usually a zip-and-link divan. Check stair and door access before ordering, as mattresses this size are often delivered in sections.

Grand super king or emperor?

The grand super king is 13cm wider; both are 200cm long. The emperor's square 200 x 200cm footprint is easier to find bases and bedding for.

What bedding fits a grand super king?

Standard super king sheets are 33cm too narrow, so you need bespoke fitted sheets or emperor bedding from specialist suppliers. An emperor duvet covers the width comfortably.

How long does a grand super king take to arrive?

Longer than a standard size, because most are made to order. Ask the retailer for the lead time before you plan around a delivery date.
