How to Make a Memory Foam Mattress


Memory foam, a type of highly resilient foam, was first developed by NASA in the 1960s to make airplane seats more comfortable. Sleeping on this supportive foam may relieve the pressure placed on your joints when you lie flat, such as when you're in bed. Because of this, it may also help you sleep better. If you cannot spend thousands of dollars on a name-brand memory foam mattress, do not despair. You can put together a very close imitation yourself for a significantly lower price.

Things You'll Need

  • High resiliency foam
  • Upholstery foam
  • Egg crate mattress
  • Box spring or bed platform
  • Bedding
  • Purchase samples of high resiliency (HR) foam from a manufacturer. Buy one of each thickness available for purchase. Choose the correct thickness for your personal taste.

  • Order two pieces of HR foam in your chosen thickness, one with a density rating of at least 2.5 pounds per cubic foot. This measurement describes the concentrated weight that the foam can support in an area of 1 cubic foot, and one with a density rating of at least 3.5 pounds per cubic foot. Choose the correct length and width dimensions for your bed size.

  • Buy a piece of high-quality plain foam, such as upholstery foam, in the correct size for your bed. Also purchase an egg crate mattress large enough to cover your entire box spring or bed platform. Both are commonly available at discount stores.

  • Build your bed on an existing box spring or a platform bed base. Place one piece of the high resiliency foam on the bottom. If piece is thicker than the other, use the thicker piece.

  • Layer on the upholstery foam, egg crate mattress and remaining piece of HR foam in this order. Dress your bed with sheets and a blanket or comforter as you normally would. You may need a deep-pocket fitted sheet to fit over the layers of mattresses.

Tips & Warnings

  • When you buy memory foam mattress toppers, pay attention to the density rating. A good density rating is 4 pounds and the higher the rating, the higher-quality your memory foam mattress will be.
