Many homeowners wonder whether outdoor sofas can be placed on interlocking foam surfaces, especially for patios, decks, or poolside areas. The short answer is yes, but with some considerations.

Interlocking foam tiles are lightweight, cushioned, and easy to install, making them a popular choice for outdoor flooring. They provide comfort underfoot and can protect furniture legs from hard surfaces. However, their softness may cause stability issues for heavier outdoor sofas. To prevent wobbling or sinking, opt for high-density foam tiles designed for heavy furniture.

Additionally, ensure the foam is UV-resistant and waterproof to withstand outdoor conditions. For better stability, place a rigid base (like plywood) beneath the sofa or choose interlocking tiles with reinforced edges. Regularly check for wear and tear, as prolonged exposure to moisture or sun can degrade foam over time.

In summary, while interlocking foam works for outdoor sofas, selecting the right type and taking precautions will ensure durability and comfort.
