A quality modern full size mattress offers a comfortable balance of space, support and value for bedrooms that need more room than a twin mattress without the footprint of a queen. Also called a double mattress, a full size mattress typically measures about 54 inches wide by 75 inches long, making it a practical choice for solo sleepers, guest rooms, teenagers and smaller primary bedrooms. Today’s full mattresses feature updated comfort technologies such as pressure-relieving memory foam, responsive hybrid coils, breathable foam layers and reinforced edge support. These materials can help promote proper spinal alignment, reduce motion transfer and create a more comfortable sleep surface for a restful night’s sleep. Finding the best modern full size mattress starts with choosing the right feel and support level for your sleep style. Side sleepers may prefer a medium or plush full mattress that cushions the shoulders and hips, while back and stomach sleepers often benefit from a medium-firm or firm mattress that helps keep the body supported. Hybrid full mattresses combine individually wrapped coils with foam comfort layers for a responsive feel and airflow, while all-foam full mattresses provide contouring comfort and quiet motion isolation. Mattress Firm makes it easy to compare quality full size mattresses from trusted brands, explore options for different budgets and find the comfortable support you need to get better zzz's.
