I have a problem with a cushion on my sofa.

It constantly moves forward within minutes of sitting on

have to keep pushing it back.

I tried attaching 4 inch wide strips of velcro but it
would not hold.

Any other ideas ?

Thanks,

Is it fabric, leather or vinyl? You can try some drawer
liner mesh/waffle pad or some thin carpet pad that they use
for area rugs. The only other solution would be to attach D
rings to the back of the cushionc and clips with elastic or
fabric straps to the back of the sofa under the bottom
inside back rail.
