What bed size should I choose?

What DFI bed size should I choose?

Now that you have made that important decision to purchase a new bed or mattress either for your new home or perhaps you or your loved ones have been experiencing some restless nights.

DFI Beds are Irelands leading online retailer and we hold a massive amount of stock in our warehouses for immediate dispatch.

Most beds that are available in the UK and Ireland are manufactured using imperial measurements but are usually sold using the approximate equivalents. This anomaly can cause confusion for some customers.

All the Mattresses and Divans we sell here at DFI are handmade in Ireland and all sizes displayed on our website are approximate. For customers who need more precise dimensions or advice please give our friendly sleep advisors a call or send us an email   www.dfibeds.com/pages/contact-us and we will be happy to advise.

Our standard sizes are:

3ft  Single. 90cm x 190cm / 3' x 6'3"

4ft  Small double. 120cm x 190cm / 4' x 6'3"

4ft6  Double. 135cm x 190cm / 4'6 x 6'3"

5ft  King size. 150cm x 200cm / 5' x 6'6"

6ft  Superking size. 180cm x 200cm / 6' x 6'6"


Single (3'0'') 

Suitable for both children and adults, ‘single’ (3’0”) beds provide a good amount of room for a single sleeper. This is the most common size for children’s beds, including bunk beds.

Small Double (4'0'') 

A ‘small double’ (4’0”) bed (also known as a ‘Queen’ or a ‘Three Quarter’) is wider than a single bed but smaller in width than a double. It provides plenty of space for one or enough room for two (although two adults may find it a little ‘cosy’). Great for smaller bedrooms and guestrooms where a standard double won’t quite fit.

Standard Double (4'6'') 

A ‘double’ bed (4’6”) is designed to sleep two adults comfortably. This is the most common and widely available size for all bed types available in Ireland.

King Size (5'0'')

A standard ‘King Size’ (5’0”) bed includes a longer length than the standard ‘double’ (6’6” instead of 6’3”).  A king-size bed will provide plenty of room for two adult sleepers, but should only be used in larger bedrooms with more space. 

Super King Size (6'0'')

The largest of all, the ‘super king’ (6’0”) sized bed provides an abundance of space for two sleeping adults; perfect for couples who prefer their own space!

These are the standard sizes of beds and mattresses in the UK, but be sure to always double-check – just in case. Some retailers have their own bed and mattresses, which is REALLY annoying because it means you have to buy both the bed frame and the mattress from the same store, instead of being able to mix and match.



If you are choosing a new divan bed from DFI (with or without a mattress ) remember that our 4FT Small Double, 4FT6 Double,  5FT Kingsize, and 6FT Superking size divans come in two easy to manage parts. These are easily joined together with our plastic U clips which you will find attached in a plastic bag and located underneath your new divan.
