Its all about the Size

Bed Size refers to the dimensions of a mattress and the names by which standard sizes are called.

 Beds themselves vary widely in size according to the size of the frame and degree of ornamentation but are sold according to the size of mattress they take. The dimensions and names vary considerably around the world, with most countries having their own standards and terminology.


 Modern sizes in metric system countries are 200 centimetres (79 in) long. The traditional "double" size standard among English speaking countries, based on Imperial units, is

 4'6" by 6'3" (54 by 75 inches (137 by 191 cm), but the sizes for other bed types tend to vary.

Swedish Sizes are sold in the UK; in particular they are the standard sizes supplied by IKEA. The length of "standard" single and double mattresses is 200 cm, rather than the usual 190 cm.

The European king size (160 cm × 200 cm) as well as contemporary Italian beds and furniture have become more popular.

Other sizes (bespoke beds) can be made to order; bed, mattress, and bed linen must all be of compatible size.

 

It is also important to note that the actual size of the mattress or base could vary. This is the nature of mattresses, particularly if made with organic and/or natural fillings, as this is very hard to keep to actual sizes. The actual size of the mattress could be as much as 1-3% bigger or smaller than the required size. 

Please be mindful of this if ordering mattresses to fit inside a bed-frame.

Please note bespoke sizes will be as close to 1-2 cm.
