What is the best foam for Outdoor Cushions?

When it comes to creating comfortable and durable outdoor cushions, the choice of foam is crucial. Not all foam is created equal, and choosing the right type of foam can make a significant difference in the lifespan and quality of your outdoor cushions. In this post, we’ll explore the different types of foam available and discuss which is the best foam for outdoor cushions.

Types of Foam for Outdoor Cushions

  1. Polyurethane Foam: Polyurethane foam is a popular choice for outdoor cushions because it’s affordable and easy to find. This foam comes in different densities, from soft to firm, and is typically used for seat cushions. It’s resistant to moisture and mildew, which makes it suitable for outdoor use. However, it’s not as durable as other foam types and can start to break down after prolonged exposure to sunlight and rain.
  2. Open-Cell Foam: Open-cell foam is a more breathable and lightweight option than polyurethane foam. It’s also more resilient, making it a better choice for cushions that will see a lot of use. Open-cell foam is designed to allow air to flow through it, which helps it dry quickly and reduces the risk of mildew. This type of foam is typically used for back cushions and pillows.
  3. Closed-Cell Foam: Closed-cell foam is the most durable and long-lasting foam option for outdoor cushions. It’s made of a dense, non-porous material that’s resistant to water, sunlight, and chemicals. This foam is also more expensive than the other two types and is typically used for high-end outdoor furniture.

Which Foam is Best for Outdoor Cushions?

While all three types of foam can be used for outdoor cushions, closed-cell foam is the best option for durability and longevity. It’s more expensive, but it will last much longer than the other two options, even with constant exposure to the elements. Closed-cell foam is also more resistant to compression, which means it won’t lose its shape or support over time.

That being said, open-cell foam is a good choice if you’re looking for a more breathable and lightweight option. It’s also suitable for pillows and back cushions, where durability isn’t as much of a concern. Polyurethane foam is a more affordable option, but it’s not as durable as the other two types and may need to be replaced more frequently.


Choosing the right foam for your outdoor cushions is an essential step in creating comfortable and durable furniture. Closed-cell foam is the best option for longevity and durability, while open-cell foam is a good choice for breathability and weight. Polyurethane foam is a more affordable option, but it’s not as durable as the other two types. Consider your needs and budget when making your decision, and don’t hesitate to invest in high-quality foam for long-lasting, comfortable outdoor furniture.
