10 Best Sofa Bed Mattresses 2026 in the United States

The MAXYOYO Folding Sofa Bed is a versatile piece of furniture designed to function both as a sofa and a bed, making it a good pick for small rooms or spaces where flexibility is important. It comes with a full-size mattress that is 16 inches thick. The mattress uses shredded foam filling, which adapts to your body shape and offers medium firmness — this helps reduce pressure and provides decent comfort for sitting or sleeping. The dark grey fabric covering is durable and adds a contemporary look, while the metal frame ensures sturdy support. Included headrest and lumbar pillows enhance back support, improving comfort during longer use. Because it folds up, it’s easy to move around or store, which is great for multi-use spaces.

The Dyonery 4.5 Inch Memory Foam Mattress Replacement is designed specifically for full-size sleeper sofas and couch beds, offering a comfortable upgrade over typical thin or spring-based sofa cushions. Its 4.5-inch thickness combined with a dual-layer construction—gel-infused memory foam on top and supportive polyurethane foam below—helps provide good pressure relief and contouring to the body. The memory foam is infused with green tea extract for freshness and uses a breathable, fiberglass-free fabric to keep you cooler during sleep. This mattress is quite versatile and can also be used in RVs, campers, or futons, making it a practical choice if you need a lightweight, portable option. A removable, machine-washable cover adds convenience, and the non-slip bottom helps keep the mattress securely in place on your sofa frame. The mattress is OEKO-TEX certified, indicating it meets certain safety and environmental standards, and a 10-year warranty offers added peace of mind.

The Signature Design by Ashley Rannis 2-in-1 Sofa Sleeper offers a blend of modern style and practical functionality, making it a suitable choice for those with limited space. One of its standout features is the inclusion of a queen-sized memory foam mattress, which can be a comfortable solution for overnight guests. With a thickness of 4 inches, the mattress may not offer the plushness some users expect for longer-term sleeping arrangements, potentially requiring an additional topper for enhanced comfort.
