FAQ: Mattress Sizes & Dimensions

Q: What is the difference between a queen and a California king?
A: A queen mattress measures 80 inches long and 60 inches wide, while a California king is slightly longer at 84 inches but narrower at 72 inches. The California king is ideal for taller individuals, while the queen is a popular choice for couples and fits more easily in most standard bedrooms.

Q: How much bigger is a queen than a full?
A: A queen mattress measures 80 inches long and 60 inches wide, offering 6 inches of additional width and 5 inches of extra length compared to a full mattress, which measures 75 inches long and 54 inches wide. This added space can make a significant difference for couples or taller individuals.

Q: Can two people sleep on a full bed?
A: Technically, two people can sleep on a full bed, but it may feel cramped. Full beds are better suited for single sleepers or smaller spaces. Couples may find a queen or larger size more comfortable.

Q: Is there a difference between a 10 and 12-inch mattress?
A: Yes, the difference is in the mattress thickness. A 12-inch mattress typically offers more support layers, resulting in better pressure relief and a more luxurious feel than a 10-inch mattress. However, it depends on personal comfort preferences.

Q: Which type of mattress is best for sleeping?
A: The best type of mattress depends on individual preferences. Memory foam offers pressure relief and contouring, hybrid mattresses combine support and comfort layers, and innerspring mattresses provide a more traditional feel with bounce. Factors like sleeping position, firmness preference, and any special needs like back support should guide your choice.
