10 Best Sofa Bed Mattresses 2025 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.

On the downside, the size is best suited for one person rather than couples, limiting its use as a double bed. Also, it comes vacuum-sealed, so you’ll need to wait about 48 hours after unpacking for it to fully expand and regain shape. The sofa lacks removable covers, which may make cleaning a bit harder. While it’s not customizable and offers only one reclining position, it is well suited for people needing a simple, space-saving solution that balances comfort with practicality.

The ZEIINPA Convertible Sleeper Sofa Bed is a versatile and modern piece of furniture designed for multiple uses, including lounging and sleeping. It features a soft and breathable Small Streak Corduroy upholstery that adds a touch of elegance while ensuring comfort. The sofa bed is built with high-density foam that offers good support and comes with plush pillows to enhance the lounging experience.

Its generous dimensions (78.5 inches in length as a sofa and 74 inches in width as a sleeper) make it spacious enough for comfortable seating and sleeping for up to four people. The non-slip pad beneath the sofa ensures stability on any surface, adding to the safety aspect of this product.

One of the standout features is its effortless setup; you can simply unfold it and it’s ready to use, which is convenient for those who dislike lengthy assembly processes. The ZEIINPA Convertible Sleeper Sofa Bed is ideal for living rooms, bedrooms, and studios, especially for those who appreciate multifunctional furniture pieces that combine style, comfort, and practicality.

The Greaton 6-Inch High-Density Foam RV Mattress Replacement is a medium-firm mattress designed primarily for short queen-sized sofa beds, camper vans, trailers, and other similar furniture. Its 6-inch thickness provides a comfortable balance, offering decent support without being too bulky. Made from high-density foam, this mattress is resilient and keeps its shape well over time, which is important if you plan to use it regularly. The foam's quality means it can quickly bounce back even after extended use, helping avoid sagging.

One of the most versatile features is how easy it is to customize the mattress by cutting or stacking layers, making it adaptable if you need a specific size or thickness. This flexibility makes it a good choice for various furniture beyond just sofa beds. The mattress comes with a cover and is shipped rolled up, so it requires a few days to fully expand after unpacking. However, the foam is medium firm, which might not suit those who prefer a softer or more plush feel. Also, at 6 inches thick, it may not offer the same cushioning as thicker mattress options.

Weighing 51 pounds, it’s relatively easy to handle compared to heavier sets. This mattress serves as a solid option for anyone needing a firm, supportive mattress replacement for a sofa bed or RV, especially if customization or space-saving is important.
