Mattress Size Comparison
Compare standard mattress sizes across regions by actual dimensions. Mattress names are regional standards — a "Queen" in one country is not necessarily the same size as a "Queen" in another.
Fit note:Mattress names are regional standards and are not universal conversions. A "Queen" in one country is not necessarily the same size as a "Queen" in another. Always compare actual width × length dimensions before purchasing.
