How to glue two memory foam pieces together

Updated February 21, 2017

Gluing pieces of memory foam together requires special glue, but is essentially an simple task for ripped or torn memory foam mattresses or pillows. You can also join two pieces of memory foam together to create a larger piece, especially if you want to top a king-bed and that size is not available. The memory foam product is a combination of polyurethane and special chemicals that create the dense, absorbent material.

  1. Spread protective covers over the surface where you plan to glue the memory foam pieces together. The glue for memory foam is an aerosol and the spray could contact your floor or tabletop. Since it is glue, it can be hard to remove.

  2. Place one piece of the memory foam on the solid surface and the other next to it. Make sure you line the pieces up carefully so you create a level and square edge for both pieces.

  3. Shake the spray can thoroughly and lift up one side of the foam's edge. Spray it thoroughly and press both sides together. Inch your way down the edges of the memory foam until you have joined both pieces together. Let the memory foam pieces dry overnight without disturbing them.

  4. Tip

    You can clean up any excess glue on your hands by rubbing the glue with mineral oil. If you are laying two pieces of memory foam on top of each other, you do not need to glue them together. Memory foam seldom slips around on surfaces, especially when placed on top of a similar surface.


    Do not apply mineral oil to the memory foam, since the oil can penetrate the cells inside the foam. True memory foam contains organic volatile compounds. Before gluing new pieces of memory foam together, let them breathe in an outdoor setting or ventilated area.
