I actually got these to raise up a gate leg folding table so it could work next to a plush carpet. They're nice and stable, just the right height, and I can use my table again without stacking unstable rubber bits! Lifted the bed just as described. Attached firmly! Excellent product, sturdy and blends in well with square table legs Bought for an Ikea file cabinet because the bottom drawer wouldn’t slide out. Easy to apply to bottom of the unit and worked well to fix the sliding drawer problem. Very solid, supports a lot of weight. Adhesive is strong and felt on the bottom keeps the floor from getting damaged; so far so good.
