AUAUY Furniture Risers 4 inchs, Bed Risers with Adjustable Screw Clamp, Sofa Bed Tables Heavy Duty Risers fit Square or Round Sofa Leg Diameter from 0''–1.5'', Supports 20,000 lbs (Black, 4Pack)

Excellent product. I was skeptical at first for the furniture balance, but I am very happy with my new Bar table that from 90 cm height increased to 103cm.

Terrible design. The raisers aren't wide enough to be stable. Certainly not for raising furniture such as chairs or beds as the slightest movement forward or backwards will result in the clamp snapping and collapse. Expensive compared to other raisers.

Lifted my wife's computer desk. Easy to fit and seem sturdy enough. Does the job, and she's very happy.

Used this to raise console table above radiator. Perfect for the job and don't look ugly .

Bought these to attach to the legs of a bathroom sink cabinet. Easy to clamp to each leg and raise the cabinet sufficiently to be flush with the sink. The product is very sturdy and overall represents value for money.

I needed a bit more height on my cats feeding station and these were super easy to fit and worked out perfect. They are plastic so i can't comment on heavier uses, but for a lightweight shelving system they were just the job. (I've had a back op so have to avoid stooping)

The media could not be loaded. They are awful. I am sorry that I bought them.

Very strong and durable. Secures perfectly to desk legs. Recommended. Great price.
