Last Updated on December 4, 2025 by Cassie Moorhead

Finding the best mattress topper for a sofa bed can improve sleep comfort instantly. A good topper adds softness and support to thin or firm sofa mattresses.

Sofa beds often have thin mattresses that feel hard or uneven. Adding a mattress topper can soften the surface and provide better support for your back. Some toppers use memory foam to contour to your body, while others offer cooling materials to keep you comfortable all night.

For example, bamboo-viscose toppers help with cooling and relieve back pain. Gel-infused memory foam toppers reduce heat and add softness. Support boards strengthen the mattress base for better durability. Choosing the right topper depends on your comfort needs and mattress size. This guide covers top options to help you rest better on your sofa bed.
