FAQs About Full Size Mattresses

How big is a full size mattress?

A full size mattress measures 54 inches wide by 75 inches long. It offers more space than a twin and is ideal for solo sleepers who want extra room.

Should I buy a twin or full size mattress?

It depends on your needs. A twin is great for kids, teens, or smaller spaces, while a full offers more width and is better for adults or growing teens who want more room to stretch out.

Will a full size mattress fit a queen bed frame?

No, a full size mattress is smaller than a queen. It won’t fit properly and may slide around or leave gaps. For the best fit and support, match your mattress size to the frame.

How do full size mattresses compare to other mattress sizes?

Full size mattresses offer more space than a twin but are smaller than queen and king mattresses, making them ideal for smaller rooms or individual sleepers.

Do you offer full size mattresses in different comfort levels?

Yes, we offer full size mattresses in a range of comfort levels, from firm to plush, ensuring there’s an option to suit your specific sleep preference.
