Why comparing mattress sizes matters
International sizing standards vary significantly. A "King" in the US is not the same as a "King" in the UK or Australia. Mistaking these can lead to purchasing bedding that doesn't fit or rugs that look awkward in your space.
Quick Rule of Thumb:
US sizes tend to be wider and longer than their UK/EU counterparts. Always check the CM measurements before buying fitted sheets or frames.
