Is a King Size Mattress Right for You?
A king mattress is a spacious mattress size measuring 76 inches wide by 80 inches long. It's ideal for couples, master bedrooms, and sleepers who want room to stretch out comfortably.
A Cal king mattress measures 72 inches wide by 84 inches long. It’s narrower but longer than a standard king, making it a great choice for taller sleepers or long master bedrooms.
A queen mattress measures 60 inches wide by 80 inches long. It’s a popular choice for couples, guest rooms, and sleepers who want extra space without the larger footprint of a king.
