Should you buy a Full Size Bed?

Whether you have growing kids, are furnishing a guest room, or are sharing a bed with a partner in a compact space, a full size is a practical choice.

Full size mattresses, also known as double beds, really are ideal for larger dorm rooms, first apartments, single sleepers who desire more sleeping space than a twin bed provides, couples who really enjoy cuddling, growing kids/young adults, and even guest rooms.

Beautyrest offers a wide range of full sized mattresses to choose from, including hybrid and innerspring options, so whether your preference is to shop online or to actually buy in-person after laying on the bed, we’re confident that you’ll find the perfect fit for you and your needs.
