  • Polyurethane foam is an excellent choice for custom sized mattresses for RVs, boats, camping trailers, where unique angles and cutouts are needed.
  • In our custom mattresses, high density polyurethane foam makes an excellent base layer for our premium natural latex and memory foam comfort layers.

Natural Latex Foam

  • FoamSource is the premier website for both pricing and ordering 100% natural Talalay latex cushions online.
  • Natural latex is the only completely natural foam available, making it the perfect choice for those who wish to avoid petroleum based foams.
  • Natural latex is the most durable foam available, sleeps cooler than memory foam, resists mold and mildew, and is antimicrobial and hypoallergenic.
  • The amazing properties of natural Talalay latex foam provide unmatched comfort, durability, and is available in three different firmness levels.
  • Natural latex, also known as latex rubber, is a sustainable natural resource, and provides a number of impressive health benefits.

Memory Foam

  • Please Note: When used in a custom cushion or mattress, memory foam must be used in conjunction with a firmer base layer for support.
  • Memory foam is considered medium in firmness, and responds to your body's pressure and temperature.
  • Memory foam conforms to the curves of the body, offering support without discernible pressure on bones and joints, improving both comfort and circulation.
  • Memory foam is a conforming layer for the top of a mattress or cushion, a support layer will be necessary.
