Frequently asked questions
Are bed sizes the same in every country?
No. The US, UK and Europe use different standard sizes, so check the chart for your region and the product’s own measurements.
Why do inches and centimeters not match exactly?
Products are made to round numbers in one system, so the other system’s figures are rounded conversions.
