Duvet Covers for Super Caesar Beds

A Super Caesar bed needs bedding on the same scale. Standard UK duvet covers are far too small for a 350 x 245cm duvet, so a specialist cover is essential for a proper fit and even distribution of the filling.

Our Super Caesar duvet covers are made specifically for oversized duvets, helping the filling sit evenly inside the cover without bunching or pulling at the corners.

What Size Is a Super Caesar Duvet Cover?

Our Super Caesar duvet covers measure 350 x 245cm. This generous size is designed for very large beds around 9ft wide and gives the extra width needed for comfortable coverage across two sleepers.

Because oversized-bed terminology is not completely standardised, we recommend choosing your cover by the actual duvet dimensions rather than relying only on the bed-size name.

Super Caesar and Alaskan King Duvet Covers

Super Caesar and Alaskan King are commonly used for similarly sized oversized beds. In our range, both names refer to duvet covers made for a 350 x 245cm duvet.

If your bed was specifically sold as an Alaskan King, you can also browse our dedicated Alaskan King duvet covers collection.

Choose Your Fabric

Our Super Caesar duvet covers are available in a range of fabrics to suit different preferences, budgets and bedroom styles.

Easy Care Percale

A practical everyday choice with a smooth, crisp feel. Easy-care polycotton is straightforward to wash and dry and requires less ironing than pure cotton.

100% Cotton Percale

Cool, breathable and naturally comfortable, cotton percale has a fresh feel and a classic matt finish.

400 Thread Count Cotton Sateen

For a softer, silkier surface, cotton sateen offers a smoother feel and a subtle lustre that gives the bed a more luxurious finish.

Bamboo & Cotton

Bamboo-blend bedding is particularly soft and smooth and makes an excellent choice if you prefer breathable bedding with a more fluid drape.

1000 Thread Count Cotton

For a more substantial luxury finish, our 1000 thread count duvet covers offer a dense, smooth feel that suits the scale of an impressive Super Caesar bed.

Zip Closure Options

Selected Super Caesar duvet covers are available with a zip fastening. On a duvet this large, a zip closure can make changing the cover easier and helps keep the duvet securely enclosed.

It also creates a neat finish along the bottom edge and reduces the chance of the duvet working its way out of the cover during the night.

Made to Order in the UK

Our specialist oversized duvet covers are made to order in the UK. Working from the roll allows us to produce bedding in sizes that are rarely available from standard high-street ranges.

This means we can cater for Super Caesar, Alaskan King and other non-standard bed sizes without compromising on fabric choice or finish.

Complete Your Super Caesar Bedding

Pair your duvet cover with one of our Super Caesar duvets and complete the bed with matching Super Caesar fitted sheets.

You can also browse the complete Super Caesar bedding collection for sheets, duvets, pillowcases and other oversized bedding.

Frequently Asked Questions

What size is a Super Caesar duvet cover?

Our Super Caesar duvet covers measure 350 x 245cm and are designed to fit duvets of the same dimensions.

Is a Super Caesar duvet cover the same as an Alaskan King duvet cover?

In our range, yes. Both names are used for duvet covers measuring 350 x 245cm, although terminology can vary between manufacturers.

Can I use a standard UK duvet cover on a Super Caesar bed?

No. Standard UK duvet covers are considerably smaller than a 350 x 245cm Super Caesar duvet and will not fit correctly.

Do Super Caesar duvet covers come with zip closures?

Selected styles are available with a zip fastening, which can make changing and securing an oversized duvet much easier.

Are Super Caesar duvet covers made in the UK?

Yes. Our specialist oversized duvet covers are made to order in the UK.
