How to Fix Memory Foam

Kent Page McGroarty

Memory foam was originally developed for NASA in the 1970s, however it was not marketed commercially until the 1990s. It is made from polyurethane and other chemicals to increase its density and viscosity.

Memory foam is used as mattress toppers to make harder mattresses more comfortable, as well as for seat cushions and the like. Occasionally rips and tears can occur in memory foam from any number of things, such as pet claws. Correct use of spray adhesive designed for memory foam will help seal such tears allowing for further use of the memory foam.

  1. Remove any and all sheets, pillows, seat cushions and bedding from the memory foam.

  2. Use an adhesive specifically made for repairing torn memory foam. The adhesive should come in spray glue form and can be purchased on commercial sites that sell memory foam. Push the tear or rip in the foam together and spray the adhesive on the tear.

  3. Allow the adhesive to dry, which should take a few seconds, before placing sheets or seat cushions back on memory foam.


The type of aerosol adhesive used for repairing memory foam can also be used to permanently bond foam to other surfaces such as fabric, wood, paper and Dacron surfaces. It is also waterproof.


Do not use memory foam adhesive on vinyl.

Ensure that the adhesive you are using is compatible with polyurethane, as some spray adhesives are designed for other types of foam and should not be used with polyurethane.
