10 Best Mattress Topper For Pull Out Sofa Bed 2025 in the United States

The Ultra Soft Full Size Mattress Topper from Niagara Sleep Solution offers notable comfort and quality, making it suitable for pull-out sofa beds. Made from a blend of polyester and bamboo-derived viscose, this topper is designed to be gentle on sensitive skin and is naturally cooling, which is beneficial for hot sleepers. It measures 54x75 inches and fits mattresses that are 8-20 inches deep, providing flexibility for various mattress types.

The topper has a thickness of 0.5 inches, which may be on the thinner side for some users who prefer more cushioning. However, the breathable and ultra-soft materials can still enhance comfort and potentially alleviate back pain. The elasticity of the fabric helps it stay in place, even on thick mattresses, and its machine-washable feature ensures easy maintenance.

Although the topper is described as having a 'hard' firmness in one instance, the material is soft, which might be confusing. Additionally, it lacks water resistance, which might be a drawback for some users. Despite these minor concerns, the topper's cooling properties, ease of use, and positive customer reviews make it a favorable option for transforming a pull-out sofa bed into a more comfortable sleeping surface.

The DUMOS Memory Foam Mattress Topper is a 3-inch thick gel-infused memory foam pad designed to add comfort to queen-size beds, including pull-out sofa beds, RVs, and campers. Its high-density foam offers good support by evenly distributing body pressure, which helps improve sleep comfort on typically firmer or less cushioned surfaces. The gel infusion and vortex technology work together to keep the topper cooler than standard memory foam, which can otherwise trap heat and become uncomfortable during the night.

Made with CertiPUR-US certified materials, it’s a safe choice for sensitive skin without off-putting odors. The size fits standard queen beds (60 x 80 inches), which is convenient for many sofa beds that match this dimension. It comes with a breathable cover and is easy to set up after unpacking—just allow it to expand in a ventilated area for a day.

This topper is not water-resistant, so spills could be an issue, especially on pull-out sofas or RV beds where accidents happen more easily. Also, the firmness is on the softer side to provide cushion, which may not suit those who prefer a firmer sleeping surface. Its weight (over 21 pounds) might make handling or moving it a bit cumbersome. For those looking to upgrade the comfort of a pull-out sofa bed or a portable sleeping space, this mattress topper provides a good balance of softness, support, and cooling features, but care should be taken regarding its softness level and maintenance requirements.

The ViscoSoft 3 Inch Pillow Top Memory Foam Mattress Topper is designed to add comfort and support to beds, including pull-out sofa beds, with its queen size fitting standard dimensions well. It features a 3-inch thickness combining gel-infused memory foam for cooling and pressure relief, topped with a plush pillow cover made from Tencel fiber — a material that’s more breathable and moisture-wicking than cotton, helping keep you cool and comfortable at night. The memory foam is CertiPur-US certified, ensuring safe and durable foam quality that resists sagging and maintains a flat sleep surface over time.

The topper’s firmness leans toward plush, making it a good choice if your sofa bed mattress feels too firm or needs a softer, more inviting layer. Its design includes an 18-inch skirt with elastic to secure it snugly around mattresses, which helps prevent slipping and is handy for the often thinner mattresses in pull-out beds. One nice eco-friendly touch is the pillowtop’s filling made from recycled ocean plastics, adding some sustainability to comfort. However, it isn’t water resistant, so spills or accidents require care, and the cover needs hand washing rather than machine cleaning, which might be less convenient. The topper is also on the heavier side at about 23 pounds, which is worth considering if you plan to move or store it regularly.

If you want a softer or more supportive feel, there’s a 4-inch version available, but this 3-inch model strikes a good balance for many users. The topper is easy to set up and comes with a 60-day return policy, so you can try it risk-free. This mattress topper represents a solid choice for improving pull-out sofa beds by adding softness, cooling properties, and a secure fit, especially if you prefer a plush sleeping surface.
