LifCratms 4 Pcs Round Furniture Bed Risers, Self-Adhesive Sofa Tables Risers Adds 1/2" Height with Felt Pad (Black, 2.56" Width)

We use them to raise the height of a bed so that the cleaning robot can pass underneath. You have to buy extras because over time and due to their weight, they lose height since they are made of foam and not a hard material.

These are not really risers, they're actually just foam pads. I'll be lucky if they last a week.

These worked instantly! As soon as I slid one of them under each front foot of my cabinet, the bottom drawer has not come open by itself since. Inexpensive fix for a multi year issue.

These really do the job. I have large feet on my couch and need to raise it so I could store a foam mattress under it for when my grandkids come to visit. Works very well.
