3 inch Bed Risers Set of 4, Heavy Duty Stackable Furniture Risers Lifters for Beds, Sofa, Tables and Chairs, Black Bed Elevator with 2.8" Square Recess

Works like it should.I put these under my bed to raise it about 3" so I could fit some larger storage units under the bed. Once I finally got them situated they were not wobbly. Be careful though if you plan to slide the bed around though once you have the bed on them. I did manage to tip them over when I did that. As a result situate whatever you are putting them under where you want to put it. If you have to move it lift the furniture and use your foot to slide the riser over then put the furniture back down.There is a pad where you can peel off the back so you can put inside the top of the riser to help smaller legs not slide around.

Bought them for a elder relative that wanted to store extra photo/art frames under the bed while not having the bed too high off the floor. These 3" bed risers worked perfectly! :)

Love these! Great fit. Strong and sturdy. Highly recommend!

Still holding up my desk after so many months

Only disappointment is the size of the opening... maybe they could include inserts? The bed frame has small metal legs, but the openings would accommodate something much, much bigger. These are even bigger than my couch legs. Inserts would keep the bed from moving around on the lifts.

I have purchased 4 sets of these chair risers. Due to rheumatoid arthritis, I have problems rising out of chairs sometimes. Raising the chairs 3” makes that task so much easier.

Arrived in a timely manner, worked perfectly

As would apply to any product's expectations: this particular product are exactly what I was looking for. Including: near exact dimensions fit, "no-worry" sturdiness and aesthetically inconspicuous.
